Reset MySQL / MariaDB password on OSX - mysql

I have installed MariaDB via Homebrew after following this guide. It has been working fine, however today the root password has expired and I cannot seem to reset it with any of the —skip-grant-tables —skip-networking type options.
So far I have tried:
brew services stop mariadb
mysqld_safe --skip-grant-tables --skip-networking
mysql_secure_installation
also tried
mysql_secure_installation --connect-expired-password
Which gives me:
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
/usr/local/Cellar/mariadb/10.3.13_1/bin/mysql: unknown option '--connect-expired-password'
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
/usr/local/Cellar/mariadb/10.3.13_1/bin/mysql: unknown option '--connect-expired-password'
Password update failed!
Cleaning up...
I've also added:
[mysqld]
default_password_lifetime=0
skip-grant-tables
to /usr/local/etc/my.cnf
Still doesn't let me update the root password with the above commands.
Brew doctor comes back clean and I'm running out of things to try.

Ended up running /usr/local/mysql/bin/mysqladmin -u root -p password and set a new password.

Log in
mysql -uroot
Then do
set password = password("your_password");

How can I successfully login with root after running mysql_secure_installation?

I am currently unable to login as root on mysql and I am not quite sure about what's going on. Here's what happened:
I ran mysql_secure_installation as recommended, to secure my mysql installation. Afterwards, I typed the default root password that was asked and then I entered:
No to setting a password for root
Yes on removing anonymous users
Yes on disallowing remote root login
Yes on removing the test database and access to it
Yes on reloading privilege tables
After completing this process, I tried accessing mysql with mysql -u root -p (entered the default password) and received this message:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
Do you have any ideas on what might have went wrong?
I also tried resetting the root password by starting mysql with --skip-grant-tables, but I am still not able to login.
I am using Ubuntu 14.04 and mysql 14.14 (LAMP stack).
I know this is an old post but the main answer is outdated and did not solve my issue.
Below my steps for future reference if anybody is having similar problems.
Stop mysql if it's running
$ sudo service mysql stop
Start mysql in safe mode
$ sudo mysqld_safe --skip-grant-tables --skip-syslog --skip-networking
If you get the error
"mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists"
Just create that folder:
$ mkdir -p /var/run/mysqld
$ chown mysql:mysql /var/run/mysqld
Open a new terminal window and log into mysql service + select mysql database:
$ mysql -u root
mysql> use mysql;
Set new password for root user:
mysql> update user set authentication_string=password('new-password') where user='root';
Flush privileges and exit mysql:
mysql> FLUSH PRIVILEGES;
mysql> exit;
Stop the safemode mysql (from the second terminal, you will see it stop in the first terminal)
$ mysqladmin -u root -p shutdown
Restart mysql
$ sudo service mysql start
You should be able to use the root user with password now to login to mysql/phpmyadmin
CentOS/Redhat:
From what I read in docs, when you run mysql_secure_installation, a temporary root password is generated and is stored in some log file.
sudo grep 'temporary password' /var/log/mysqld.log
Debian/Ubuntu:
During the packages installation, you get a prompt asking for the root password. If you don’t set it up, MySQL’s root user is created without a password. We can read the following line in package installation output:
Shell
2016-05-16T07:27:21.532619Z 1 [Warning] root#localhost is created with
an empty password ! Please consider switching off the
--initialize-insecure option.
but it is configured with the auth_socket plugin. You will only be able to connect using the UNIX socket, therefore any attempt to connect using your local IP or the network fails. Later on, you can change the password to allow connections from the network (as explained in this blog post).
Source
All we can do now is to see the root password. Lets change the root password since you cannot understand hashed password even if we can see it:
sudo service mysql stop
sudo mysqld_safe --skip-grant-tables --skip-syslog --skip-networking
then run mysql in a new terminal
mysql -u root
and run the following query, after changing the password
UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
FLUSH PRIVILEGES;
quit the mysql safe mode and start mysql service by
mysqladmin shutdown
sudo service mysql start
just run this script by root , you need custormize you password
mysqlpassword=password
/usr/bin/mysqladmin -u root password "$mysqlpassword"
#configure mysql login privileges
echo "grant all privileges on *.* to root#\"localhost\" identified by \"$mysqlpassword\";show databases;" |mysql -u root -p$mysqlpassword

Unable to access MySQL after it automatically generated a temporary password

I have erased and installed OSX 10.11 El Capitan and I have been following through this tutorial to get MySQL up and running on the new OS X. The first step was to download MySQL For Mac OS X 10.9 (x86, 64-bit), DMG Archive (works on 10.11, they recommended in the tutorial). While I were finishing installing the MySQL, I got the message saying that :
2015-10-25T02:10:54.549219Z 1 [Note] A temporary password is generated for root#localhost: R>gFySuiu23U
If you lose this password, please consult the section How to Reset the Root Password in the MySQL reference manual.
That was weird, I have never seen that kind of message. After that, I started MySQL via the Preference Pane and then use /usr/local/mysql/bin/mysql -v command on the terminal for another step. I got an error message saying that :
ERROR 1045 (28000): Access denied for user 'cheetah'#'localhost' (using password: NO)
I have also tried to access database through Sequel Pro using root as username and blank password, I got access denied message saying that :
Unable to connect to host 127.0.0.1 because access was denied.
Double-check your username and password and ensure that access from your current location is permitted.
MySQL said: Access denied for user 'root'#'localhost' (using password: NO)
Okay, I also tried this again using root as a username but 'R>gFySuiu23U' as a password (which was generated from MySQL). I got connection failed message saying that :
Unable to connect to host 127.0.0.1, or the request timed out.
Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).
MySQL said: Your password has expired. To log in you must change it using a client that supports expired passwords.
How could I solve this problem? I remember that MySQL has never got automatically generated a temporary password like this, hasn't it ?
Try this:
mysql -u root -h 127.0.0.1 -p
Enter password: (enter the random password here)
Ref:https://dev.mysql.com/doc/refman/5.7/en/data-directory-initialization-mysqld.html
Following this, you may reset your password using
ALTER USER 'root'#'localhost' IDENTIFIED BY 'new-password';
This is what worked for me on OS X Yosemite running MySql v5.7 (installed from the .dmg).
cd /usr/local/mysql/bin
./mysql -u root -p --connect-expired-password
(Enter the temporary password generated by the installer.)
This gets you into sandbox mode and mysql> prompt. Then set desired root password with SET PASSWORD:
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('mySuperSecretPassword');
Now that the password MySQL had generated is expired, the problem is reduced to getting this password to work again (1) or generate a new one (2). This can be accomplished by running MySQL with the skip-grant-tables option which would make it ignore the access rights:
Stop your MySQL server.
Add the below at the end of the [mysqld] section of my.cnf file and save it.
skip-grant-tables
Start MySQL server.
In terminal, type
mysql -u root -p
to get into MySQL command prompt.
In the command prompt, type
USE mysql;
to get into the mysql database where it keeps database users.
Type
UPDATE user SET password_expired = 'N' WHERE User = 'root';
to let MySQL know the password is not expired (1) or
UPDATE user SET authentication_string = PASSWORD('YourNewPassword'), password_expired = 'N' WHERE User = 'root';
to assign a new password YourNewPassword to root (2).
Doing these steps under OSX 10.11 El Capitan and MySQL 5.7.X, should do the trick.
Considering that you already have MySQL installed then..
Open a terminal window and type:
sudo /usr/local/mysql/support-files/mysql.server stop
sudo mysqld_safe --skip-grant-tables
Since the command fired in the step 2 will be under on going state, you need to open another terminal window and then type:
mysql -u root -p
UPDATE mysql.user SET password_expired='N', authentication_string=PASSWORD('') WHERE User='root';
quit;
sudo /usr/local/mysql/support-files/mysql.server restart
Important: in the step 2 you must replace for your password.
Hope it will wok for you.
MySQL password expired
Resetting the password will solve the problem temporarily, however, from MySQL 5.7.4 to 5.7.10 (I think to encourage better security) the default value for the default_password_lifetime variable is 360 (about a year). For those versions, if you make no changes to this variable (or to individual user accounts) all user passwords expire after 360 days.
Typically, from a script you might get the message: "Your password has expired. To log in you must change it using a client that supports expired passwords."
So, to prevent automatic password expiry, log in as root (mysql -u root -p), then, for clients that automatically connect to the server (e.g. scripts.) change the password expiration settings for those clients:
ALTER USER 'script'#'localhost' PASSWORD EXPIRE NEVER;
or you can disable automatic password expiration for all users:
SET GLOBAL default_password_lifetime = 0;

I'm running macOS Sierra(10.12.3) and I installed mysql-5.7.17-macos10.12-x86_64.dmg.
The answer from #lesley worked for me with the exception that I needed to add ./ to ensure I was calling the mysql binary in my current working directory. Which is where the aforementioned package was installed.
If you cd to /usr/local/mysql/bin and run mysql -u root -p --connect-expired-password, you could receive the following error.
mysql: unknown option '--connect-expired-password'
I did. Because simply running mysql without providing a path, called a previously installed version of the MariaDB client.
So to ensure you are executing the correct binary, you can either
provide the absolute path
/usr/local/mysql/bin/mysql -u root -p --connect-expired-password
or the relative path after changing directories
cd /usr/local/mysql/bin
./mysql -u root -p --connect-expired-password
Both ways should work. Once you are connected to the client, the instruction are the same as above from #lesley.
Enter your temporary password generated by the installer and set your new password.
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('yourNewPassword');
I faced the same problem. I followed the installation process guide from https://www.ntu.edu.sg/home/ehchua/programming/sql/MySQL_HowTo.html and downloaded DMG archive and installed MySQL on my MAC OS X 10.12.2.
Finally executed the following commands on new Terminal.
cd /usr/local/mysql/bin
./mysql -u root -p --connect-expired-password
It worked.
Answer 7 worked for me: El capitan, MySQL installed from dmg and autogenerated password, but made sure to cd to /usr/local/bin/mysql before entering ./mysql -root -p Obvious, but I didn't the first time.
Now to find where all my databases and tables are and how to link them in.
For Mysql 5.7 I use
shell $ > sudo grep 'temporary password' /var/log/mysqld.log
This particular one did the trick for me:
As specified in this link: https://www.variphy.com/kb/mac-os-x-reset-mysql-root-password
Do all the steps except executing
UPDATE mysql.user SET Password=PASSWORD('NewPassword') WHERE User='root';
Execute
UPDATE mysql.user
SET authentication_string = PASSWORD('MyNewPass'), password_expired = 'N'
WHERE User = 'root' AND Host = 'localhost';
And then execute
FLUSH PRIVILEGES;
The another way to solve this issue is to use an older version of MySQL instead.
I have uninstalled MySQL version 5.7.9 for Mac OS X 10.9 (x86, 64-bit), DMG Archive and then install the older version, MySQL version 5.6.7 for Mac OS X 10.9 (x86, 64-bit), DMG Archive. This issue is solved. The given autogenerated password before finishing installation of this older version is gone and I can ultimately access the database using root as username and a blank password. Everything is working like a charm!
I installed view brew, and I had the same error message until I noticed this caveat:
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
To connect run:
mysql -uroot
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
I got around this problem by running
'mysql -u root -p --connect-expired-password'
Then input the expired auto-gen password from mysql. Finally got in. Selected mysql db with
'use mysql'
and then updated user 'root' pw with
'ALTER USER 'root'#'localhost' IDENTIFIED BY 'your new password'
Installing MySQL manually by downloading packages for the first time generates a default password for root. Copy and save that. If not done somehow on successive re-installations it does not show that password.
Thus you cannot login to root.
Do the following :
Find mysql related entries from system
sudo find / -name mysql
Remove all mysql related entries by doing rm -rf <mysql_entries_above>
Download latest mysql-server and intall it.
You will be promted with a default password which you need to copy.
Run mysql_secure_installation and paste that password when asked for root.
Subsequently follow the steps and change admin password when prompted for.
Restarting Mysql server worked for me.
But in Mysql80-Server, it is more complicated than 5.7. In MySQL80 not allow you to update or change password during the config in my.cnf in state "skip grant table". So you need 3 big steps to do
I) change my.cnf to skip-grant-table
II) login MySQL with blank password & update table to blank password
III) restart mysql and login with blank password and update to new password
Step to do: (whatever, you forgot root password, temporary password gen by installation not work, etc. please follow the steps below) In my case on FreeBSD 12.2
stop your mysql server by
/usr/local/etc/rc.d/mysql-server stop
recheck again whether it is really stop (in case more serious problem than that)
/usr/local/etc/rc.d/mysql-server status
mysql is not running.
find your my.cnf file and add "skip-grant-tables" to it.
(normally before [Mysqldump] head)
restart mysql
/usr/local/etc/rc.d/mysql-server start
login to mysql
mysql -u root -p
when it ask for password, just press enter and you will log into mysql
select DB to use
use mysql
look at the table user
select user, authentication_string,password_expired from user;
update to blank password
UPDATE user SET authentication_string = '', password_expired='N' WHERE User = 'root';
quit mysql and make mysql stop
goto file my.cnf then take "skip-grant-tables" out of file.
restart mysql again with "mysql -u root -p" enter the blank password
then
ALTER USER 'root'#'localhost' IDENTIFIED WITH
caching_sha2_password BY 'YourNewPassword';
quit mysql and make mysql stop
restart mysql again then you will login with your new password
This may happens when you have installed mysql before.
Try the password you set for the last version of mysql.
This did work for me.

How do I access PHPMyAdmin in Ubuntu?

I am trying to log into phpmyadmin however when I type username as "root" and password as blank, I get the error:
Login without a password is forbidden by configuration
I had a look at the accepted answer here: Can anyone confirm that phpMyAdmin AllowNoPassword works with MySQL databases?
I uncommented the line (in /etc/phpmyadmin/config.inc.php) :
$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
but to no avail
Any help would be appreciated.
Try to reset your password in your MySQL like this:
Set / change / reset the MySQL root password on Ubuntu Linux. Enter the following lines in your terminal.
Stop the MySQL Server.
sudo /etc/init.d/mysql stop
Start the mysqld configuration.
sudo mysqld --skip-grant-tables &
Login to MySQL as root.
mysql -u root mysql
Replace YOURNEWPASSWORD with your new password!
UPDATE user SET
Password=PASSWORD('YOURNEWPASSWORD') WHERE User='root'; FLUSH
PRIVILEGES; exit;
Note: This method is not regarded as the securest way of resetting the password. However it works.

How to Reset the Root Password

ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)

I have been following a manual to install a software suite on Ubuntu. I have no knowledge of MySQL at all. I have done the following installations on my Ubuntu.
sudo apt-get update
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-client-5.5
sudo apt-get install mysql-common
sudo apt-get install glade
sudo apt-get install ntp
Then I do
cd ~/Desktop/iPDC-v1.3.1/DBServer-1.1
mysql -uroot -proot <"Db.sql"
I ended up with the following error message.
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
How may I fix it and continue?
Note: For MySQL 5.7+, please see the answer from Lahiru to this question. That contains more current information.
For MySQL < 5.7:
The default root password is blank (i.e., an empty string), not root. So you can just log in as:
mysql -u root
You should obviously change your root password after installation:
mysqladmin -u root password [newpassword]
In most cases you should also set up individual user accounts before working extensively with the database as well.
I was recently faced with the same problem, but in my case, I remember my password quite alright, but it kept on giving me the same error. I tried so many solutions, but still none helped. Then I tried this:
mysql -u root -p
After which it asks you for a password like this
Enter password:
And then I typed in the password I used. That's all.
I was able to solve this problem by executing this statement
sudo dpkg-reconfigure mysql-server-5.5
Which will change the root password.
You have to reset the password! Steps for Mac OS X (tested and working) and Ubuntu:
Stop MySQL using
sudo service mysql stop
or
sudo /usr/local/mysql/support-files/mysql.server stop
Start it in safe mode:
sudo mysqld_safe --skip-grant-tables --skip-networking
(the above line is the whole command)
This will be an ongoing command until the process is finished, so open another shell/terminal window, log in without a password:
mysql -u root
mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
As per #IberoMedia's comment, for newer versions of MySQL, the field is called authentication_string:
mysql> UPDATE mysql.user SET authentication_string =PASSWORD('password') WHERE User='root';
Start MySQL using:
sudo service mysql start
or
sudo /usr/local/mysql/support-files/mysql.server start
Your new password is 'password'.
Note: for version of MySQL > 5.7 try this:
update mysql.user set authentication_string='password' where user='root';
It happens when your password is missing.
Steps to change the password when you have forgotten it:
Stop MySQL Server (on Linux):
sudo systemctl stop mysql
Start the database without loading the grant tables or enabling networking:
sudo mysqld_safe --skip-grant-tables --skip-networking &
The ampersand at the end of this command will make this process run in the background, so you can continue to use your terminal and run mysql -u root (as root). It will not ask for a password.
If you get error like as below:
2018-02-12T08:57:39.826071Z mysqld_safe Directory '/var/run/mysqld' for UNIX
socket file don't exists.
mysql -u root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)
[1]+ Exit 1
Make MySQL service directory.
sudo mkdir /var/run/mysqld
Give MySQL user permission to write to the service directory.
sudo chown mysql: /var/run/mysqld
Run the same command in step 2 to run MySQL in background.
Run mysql -u root. You will get the MySQL console without entering a password.
Run these commands
FLUSH PRIVILEGES;
For MySQL 5.7.6 and newer
ALTER USER 'root'#'localhost' IDENTIFIED BY 'new_password';
For MySQL 5.7.5 and older
SET PASSWORD FOR 'root'#'localhost' = PASSWORD('new_password');
If the ALTER USER command doesn't work use:
UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';
Now exit
To stop the instance started manually:
sudo kill `cat /var/run/mysqld/mysqld.pid`
Restart MySQL
sudo systemctl start mysql
At the initial start up of the server the following happens, given that the data directory of the server is empty:
The server is initialized.
SSL certificate and key files are generated in the data directory.
The validate_password plugin is installed and enabled.
The superuser account 'root'#'localhost' is created. The password for the superuser is set and stored in the error log file.
To reveal it, use the following command:
shell> sudo grep 'temporary password' /var/log/mysqld.log
Change the root password as soon as possible by logging in with the generated temporary password and set a custom password for the superuser account:
shell> mysql -u root -p
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass5!';
If the problem still exists, try to force changing the password:
/etc/init.d/mysql stop
mysqld_safe --skip-grant-tables &
mysql -u root
Set up a new MySQL root user password:
use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;
Stop the MySQL server:
/etc/init.d/mysql stop
Start the MySQL server and test it:
mysql -u root -p
If none of the other answers work for you, and you received this error:
mysqld_safe Logging to '/var/log/mysql/error.log'.
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
[1]+ Exit 1 sudo mysqld_safe --skip-grant-tables
Follow the below commands step by step until you reset your password:
# Stop your server first
sudo service mysql stop
# Make the MySQL service directory.
sudo mkdir /var/run/mysqld
# Give MySQL permission to work with the created directory
sudo chown mysql: /var/run/mysqld
# Start MySQL, without permission and network checking
sudo mysqld_safe --skip-grant-tables --skip-networking &
# Log in to your server without any password.
mysql -u root mysql
# Update the password for the root user:
UPDATE mysql.user SET authentication_string=PASSWORD('YourNewPasswordBuddy'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';
# If you omit (AND Host='localhost') section, it updates
# the root password regardless of its host
FLUSH PRIVILEGES;
EXIT;
# Kill the mysqld_safe process
sudo service mysql restart
# Now you can use your new password to log in to your server
mysql -u root -p
# Take note for remote access. You should create a remote
# user and then grant all privileges to that remote user
I came across this very annoying problem and found many answers that did not work. The best solution I came across was to completely uninstall MySQL and reinstall it. On reinstall you set a root password and this fixed the problem.
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.5 mysql-client-core-5.5
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get autoremove
sudo apt-get autoclean
I found this code elsewhere, so I don't take any credit for it. But it works. To install MySQL after uninstalling it, I think DigitalOcean has a good tutorial on it. Checkout my gist for this.
How to install MySQL on Ubuntu (which works)
I am using Ubuntu 16.04 (Xenial Xerus) and installed MySQL 5.7.
I had the same issue
Login denied for root user.
I tried the below steps:
dpkg --get-selections | grep mysql (to get the version of MySQL).
dpkg-reconfigure mysql-server-5.7
mysql -u root -p
Without -p that doesn't prompt you to ask password. Once you are in, you can create a user with a password by following steps:
CREATE USER 'your_new_username'#'your-hostname' IDENTIFIED BY 'your-password';
GRANT ALL PRIVILEGES ON *.* to 'your_new_username'#'your-hostname' WITH GRANT OPTION;
Exit from the root and log in from the <name> you gave above.
mysql -u <your_new_username> -p
For some reason still just typing MySQL does not work. At all. I suggest to make it a habit to use mysql -u <name> -p.
In the terminal, just enter:
mysql -u root -p
Then it will ask the password from you.
I installed MySQL as root user ($SUDO) and got this same issue
Here is how I fixed it:
sudo cat /etc/mysql/debian.cnf
This will show details as:
# Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock
Above we can see the password. But we are just going to use(GUx0RblkD3sPhHL5) that in the prompt.
`mysql -u debian-sys-maint -p
Enter password: `
Now provide the password (GUx0RblkD3sPhHL5).
Now exit from MySQL and log in again as:
`mysql -u root -p
Enter password: `
Now provide the new password. That's all. We have a new password for further uses.
It worked for me.
For those for whom the current answers didn't work can try this (tested on macOS):
mysql -h localhost -u root -p --protocol=TCP
After this, a password will be asked from you and you should use your OS user password. Then when you get into MySQL you can run:
select Host, User from mysql.user;
And you should see:
MySQL [(none)]> select Host, User from mysql.user;
+-----------+------------------+
| Host | User |
+-----------+------------------+
| localhost | mysql.infoschema |
| localhost | mysql.session |
| localhost | mysql.sys |
| localhost | root |
+-----------+------------------+
And from here you can change the configurations and edit the password or modify the grants.
Please read the official documentation: MySQL: How to Reset the Root Password
If you have access to a terminal:
MySQL 5.7.6 and later:
mysql
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
MySQL 5.7.5 and earlier:
mysql
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
I am using mysql-5.7.12-osx10.11-x86_64.dmg on Mac OS X.
The installation process automatically sets up a temporary password for the root user. You should save the password. The password can not be recovered.
Follow the instructions:
Go to cd /usr/local/mysql/bin/
Enter the temporary password (which would look something like, "tsO07JF1=>3")
You should get the mysql> prompt.
Run, SET PASSWORD FOR 'root'#'localhost' = PASSWORD('{YOUR_PASSWORD}'); If you wish to set your password: "root" then the command would be, SET PASSWORD FOR 'root'#'localhost' = PASSWORD('root');
Run ALTER USER 'root'#'localhost' PASSWORD EXPIRE NEVER;
Run exit
Run ./mysql -u root -p
Type your password. In my case I would type, "root" (without quote)
That's all.
For convenience, you should add "/usr/local/mysql/bin" to your PATH environment variable.
Now from anywhere you can type ./mysql -u root -p and then type the password and you will get the mysql> prompt.
The answer may sound silly, but after wasting hours of time, this is how I got it to work:
mysql -u root -p
I got the error message
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
Even though I was typing the correct password (the temporary password you get when you first install MySQL).
I got it right when I typed in the password when the password prompt was blinking.
If you have MySQL as part of a Docker image (say on port 6606) and an Ubuntu install (on port 3306) specifying the port is not enough:
mysql -u root -p -P 6606
will throw:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
as it's trying to connect to localhost by default, specifying your local IP address fixes the issue:
mysql -u root -p -P 6606 -h 127.0.0.1

Answer for Ubuntu 20.04 (Focal Fossa) (maybe other distributions as well).
After days of wandering around... and having none of those answers working for me, I did this and it worked!
Always in a Bash shell:
sudo systemctl disable mysql
In order to stop the daemon from starting on boot.
sudo apt purge mysql-server
and
sudo apt purge mysql-community-server*
There, it warns you you'll erase configuration files... so it's working! Because those are the ones making trouble!
sudo autoremove
To delete all the left behind packages.
Then (maybe it's optional, but I did it) reboot.
Also, I downloaded mysql-server-8.0 from the official MySQL webpage:
sudo apt install mysql-server
A signal that it's working is that when you enter the command above, the system asks you to enter the root password.
Finally:
mysql -u root -p
And the password you entered before.
If the problem still exists, try to force changing the password.
Stop MySQL Server (on Linux):
/etc/init.d/mysql stop
Stop MySQL Server (on Mac OS X):
mysql.server stop
Start the mysqld_safe daemon with --skip-grant-tables:
mysqld_safe --skip-grant-tables &
mysql -u root
Set up a new MySQL root user password:
use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;
Stop MySQL Server (on Linux):
/etc/init.d/mysql stop
Stop MySQL Server (on Mac OS X):
mysql.server stop
Start the MySQL server service and test to log in by root:
mysql -u root -p
I also came across the same problem. I did:
Open your cmd
Navigate to C:\Program Files\MySQL\MySQL Server 8.0\bin>
(where MySQL Server 8.0 may be different depending on the server you installed)
Then put the following command mysql -u root -p
It will prompt for the password... simply hit Enter, as sometimes the password you entered while installing is changed by to blank.
Now you can simply access the database.
This solution worked for me on the Windows platform.
By default, the password will be null, so you have to change the password by doing the below steps.
Connect to MySQL
root# mysql
Use mysql
mysql> update user set password=PASSWORD('root') where User='root';
Finally, reload the privileges:
mysql> flush privileges;
mysql> quit
Just one line and it solved my issue.
sudo dpkg-reconfigure mysql-server-5.5
In Ubuntu 16.04 (Xenial Xerus) and MySQL version 5.7.13, I was able to resolve the problem with the steps below:
Follow the instructions from section B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems
MySQL 5.7 reference manual
When I tried #sudo mysqld_safe --init-file=/home/me/mysql-init & it failed. The error was in /var/log/mysql/error.log:
2016-08-10T11:41:20.421946Z 0 [Note] Execution of init_file '/home/me/mysql/mysql-init' started.
2016-08-10T11:41:20.422070Z 0 [ERROR] /usr/sbin/mysqld: File '/home/me/mysql/mysql-init' not found (Errcode: 13 - Permission denied)
2016-08-10T11:41:20.422096Z 0 [ERROR] Aborting
The file permission of mysql-init was not the problem. We need to edit AppArmor permissions.
Edit by sudo vi /etc/apparmor.d/usr.sbin.mysqld
....
/var/log/mysql/ r,
/var/log/mysql/** rw,
# Allow user init file
/home/pranab/mysql/* r,
# Site-specific additions and overrides. See local/README for details.
#include <local/usr.sbin.mysqld>
}
Do sudo /etc/init.d/apparmor reload
Start mysqld_safe again. Try step 2 above. Check file /var/log/mysql/error.log. Make sure there is no error and the mysqld is successfully started.
Run mysql -u root -p
Enter password:
Enter the password that you specified in mysql-init. You should be able to log in as root now.
Shutdown mysqld_safe by sudo mysqladmin -u root -p shutdown
Start mysqld the normal way by sudo systemctl start mysql
While the top answer (with mysqladmin) worked on macOS v10.15 (Catalina), it did not work on Ubuntu. Then I tried many of the other options, including a safe start for MySQL, but none worked.
Here is one that does:
At least for the version I got 5.7.28-0ubuntu0.18.04.4 answers were lacking IDENTIFIED WITH mysql_native_password. 5.7.28 is the default on the current LTS and thus should be the default for most new new systems (till Ubuntu 20.04 (Focal Fossa) LTS comes out).
I found Can't set root password MySQL Server and now applied
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'your_pass_here';
which does work.
The error that I faced was:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO)
It was a problem with the port running on.
By default, MySQL is running on port 3306.
You can check that on by running
in a 32-bit system:
sudo /opt/lampp/manager-linux.run
in a 64-bit system:
sudo /opt/lampp/manager-linux-x64.run
and click on the Configure button.
In my case the port was running on 3307, and I used the command
mysql -u root -p -P 3307 -h 127.0.0.1
Copied from this link, I had the same problem and this solved the problem. After we add a password for the database, we need to add -p (password-based login), and then enter the password. Otherwise, it will return this error:
mysql -u root -p
Because your error message says "PASSWORD: YES" this means you are are using the wrong password. This happened to me also. Luckily I remembered my correct password, and was able to make the DB connection work.
In recent MySQL versions there isn't any password in the mysql.user table.
So you need to execute ALTER USER. Put this one line command into the file.
ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
And execute it as an init file (as the root or mysql user):
mysqld_safe --init-file=/home/me/mysql-init &
MySQL server need to be stopped to start mysqld_safe.
Also, there may be a problem with AppArmor permissions to load this init file. Read more in AppArmor and MySQL.
If you haven't set password yet, then run mysql -uroot. It works for me.
On Mac, if you have a problem in logging in with the first password you were given in installation, maybe you can just simply kill the MySQL process and then try.
So:
run the following command to find the PID of MySQL:
ps -aef | grep mysql | grep -v grep
kill the process:
kill -15 [process id]
Then you can log in with the initial password using this command:
mysql -uroot -p
Which asks you to enter your password. Just enter the initial password.

Problems installing openEMM on Centos 6 running Plesk 11

I am trying to install openEMM on a Centos 6 VDS and have run into a snag. I am following the instructions on this page: http://www.roothelp.net/install-openemm-on-centos-6-x/. Everything has gone along fine until I reached the following commands:
service mysqld start
/usr/bin/mysql_secure_installation
cd /usr/share/doc/OpenEMM-2013/
mysqladmin -u root -p create openemm
The service starts fine, but when I run /usr/bin/mysql_secure_installation I get the following:
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and you
haven't set the root password yet, the password will be blank, so you
should just press enter here.
Enter current password for root (enter for none):
This is where the problems start. Apparently Plesk 11 does not create a root user account, using "admin" instead. None of my passwords work here, neither my actual SSH root password, my admin password, or any other password I've assigned. I even started mysql with this script to ensure I had the correct root password:
>UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
>FLUSH PRIVILEGES;
I tried this to ensure I had the correct password: /usr/local/psa/bin/admin --show-password
None of this has worked, and I am unable to run the command. How can I get around this? If I skip that command (GoDaddy support advised me that it was only configuring MySql, which is already installed with Plesk) and try to run
mysqladmin -u root -p create openemm
I am again asked for a root password and none work. I also tried this command instead, using the admin password but still had the same problem.
mysqladmin -u admin -p create openemm
I suspect I'll have to create a database called openemm through Plesk. Any ideas?
If you haven't set the mysql root password you can set it through the command
`$> mysqladmin -u root password "yourpassword"`
and if you want to change (or update) a root password, then you need to use the following command:
$> mysqladmin -u root -p'oldpassword' password newpass
Then you can create your database. In your case I think the mysql root password is just entered as the secure script asked you.
