so i installed the MySQL application for the first time. firstly i saw the command line client is not opening so i searched for solutions. they said i must go to the bin directory and run it manually. and after i run the cmd mysql -uroot -p and run it and enter password, it gives me the error: ERROR 1045 (28000): Access denied for user 'root'#'localhost' i tried every single solution on stackoverflow including disabling permissions, running manually which i mentioned above, starting the service from service.msc, running it with password and without.... it just doesnt want to work.
appreciate any help in advance.
GENERIC MYSQL INFO
To start with, read the mysql manual: https://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html
The steps will show you how to shut down the service and start it with an overriding command that doesn't require passwords, then you reset the password. From the manual:
Stop the MySQL server, then restart it with the --skip-grant-tables option. This enables anyone to connect without a password and with all privileges and disables account-management statements such as ALTER USER and SET PASSWORD. Because this is insecure, you might want to use --skip-grant-tables in conjunction with --skip-networking to prevent remote clients from connecting.
Connect to the MySQL server using the mysql client; no password is necessary because the server was started with --skip-grant-tables:
shell> mysql
In the mysql client, tell the server to reload the grant tables so that account-management statements work:
mysql> FLUSH PRIVILEGES;
Then change the 'root'#'localhost' account password. Replace the password with the password that you want to use. To change the password for a root account with a different hostname part, modify the instructions to use that hostname.
MySQL 5.7.6 and later:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
MySQL 5.7.5 and earlier:
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass');
Or directly on the user table:
UPDATE mysql.user SET password=PASSWORD('mynewpassword') WHERE user='root';
XAMPP SPECIFIC
Stop the MySQL service. Open a command window. Change to the XAMPP MySQL directory:
> cd \xampp\mysql\bin\
Run the service without security (note you are running mysqld, not mysql):
> mysqld.exe --skip-grant-tables
The MySQL service will be running in this window, so open another command window and switch to the XAMPP MySQL directory:
> cd \xampp\mysql\bin\
Run the MySQL client:
> mysql
Update the password:
mysql> UPDATE mysql.user SET password=PASSWORD('mynewpassword') WHERE user='root';
Exit MySQL:
mysql> \q
Use task manager to cancel the mysqld.exe that is still running. Restart the mysql service.
I got the answer myself. Seemingly, if you get this error, it means that you need to reset your password. You can learn how to do that in MySQL from this link.
And don't forget to change the 5.7 version with your currently installed version in using commands (mine was 8.0).
After that, everything was working fine for me.

I have installed mysql with Homebrew and I just can't access it.
When I run mysql -uroot, it says, I can't access. So I though maybe there was a password set. So I deleted /usr/local/var/mysql and ran mysqld --initialize. This output, besides other things:
A temporary password is generated for root#localhost: randomPassword
So I tried mysql -uroot -p'randomPassword'. But this still doesn't work. What is my password? I may have installedmysql` with Homebrew before that, but I can't imagine that the old password is still saved somewhere.
I don't have experience of MacOS installs. In my experience of Linux installs, it prompts for the user to enter a root password on install.
There are however a wealth of instructions around on how to reset the root password if not known. I have used the --skip-grant-tables method many times.
Stop the MySQL server
Restart it with --skip-grant-tables
Open up the mysql command line client
mysql> FLUSH PRIVILEGES;
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass'; for MySQL 5.7.6 and later, or
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('MyNewPass'); for MySQL 5.7.5 and earlier

MySQL Manual
I've just installed xampp, and am using command line to write mySQL.
I am using 'root' with no password and can connect to mysql but cannot CREATE DATABASE as I get the error 1044 access denied for user '' # 'localhost'. I am logged in as -uroot.
I have privileges in phpMyadmin to do what I want, but, in command line I seem to have no write privileges. I've looked at all the other related posts on this topic but to no avail. I cannot GRANT privileges as I have none anyway.
Are you logging into MySQL as root? You have to explicitly grant privileges to your "regular" MySQL user account while logged in as MySQL root.
First set up a root account for your MySQL database.
In the terminal type:
mysqladmin -u root password 'password'
To log into MySQL, use this:
mysql -u root -p
To set the privileges manually start the server with the skip-grant-tables option, open mysql client and manually update the mysql.user table and/or the mysql.db tables. This can be a tedious task though so if what you need is an account with all privs I would do the following.
Start the server with the skip-grant-tables option
Start mysql client (without a username/password)
Issue the command
flush privileges;
which forces the grant tables to be loaded.
Create a new account with the GRANT command something like this (but replacing username and password with whatever you want to use.
GRANT ALL on *.* to 'username'#'localhost' identified by 'password';
Restart the server in normal mode (without skip-grant-tables) and log in with your newly created account.
Refer this MySQL docs.
navigate do C:\xampp\mysql\bin\ and make sure the file mysql.exe is in that folder.
mysql -uroot -p
if dont have a password just press enter.
the prompt changes to
mysql>
do your mysql commands
By default there is no password is set for root user in XAMPP.
You can set password for root user of MySQL.
Navigate to
localhost:80/security/index.php
and set password for root user.
Note:Please change the port number in above url if your Apache in on different port.
Open XAMPP control panel Click "Shell" button
Command prompt window will open now in that window type
mysql -u root -p;
It will ask for password type the password which you have set for root user.
There you go ur logged in as root user :D Now do what u want to do :P
Gain access to a MariaDB 10 database server
After stopping the database server, the next step is to gain access to the server through a backdoor by starting the database server and skipping networking and permission tables. This can be done by running the commands below.
sudo mysqld_safe --skip-grant-tables --skip-networking &
Reset MariaDB root Password
Now that the database server is started in safe mode, run the commands below to logon as root without password prompt. To do that, run the commands below
sudo mysql -u root
Then run the commands below to use the mysql database.
use mysql;
Finally, run the commands below to reset the root password.
update user set password=PASSWORD("new_password_here") where User='root';
Replace new_password _here with the new password you want to create for the root account, then press Enter.
After that, run the commands below to update the permissions and save your changes to disk.
flush privileges;
Exit (CTRL + D) and you’re done.
Next start MariaDB normally and test the new password you just created.
sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
Logon to the database by running the commands below.
sudo mysql -u root -p
source: https://websiteforstudents.com/reset-mariadb-root-password-ubuntu-17-04-17-10/
I had the same issue, and it turned out to be that MariaDB was set to allow only root to log in locally via the unix_socket plug-in, so clearing that setting allowed successfully logging in with the user specified on the command line, provided a correct password is entered, of course.
See this answer on Ask Ubuntu
I re-installed the ODBC connector msi and re-installed mySQL directly (aside from xampp) and it now works. It was a connector problem I think, as SHOW DATABASES wasn't actually showing my databases at all.
My 'root' login wasn't getting access to the DB, which made it seem like it had limited priviliges but it actually wasn't connected properly.
Server file only change name folder
etc/mysql
rename
mysql-
this might help on Ubuntu:
go to /etc/mysql/my.cnf and comment this line:
bind-address = 127.0.0.1
Hope this helps someone, I've been searching for this a while too
Cheers
You mustn't have a space character between -u and the username:
mysql -uroot -p
# or
mysql --user=root --password
I have installed MySQL server 5 on redhat linux. I can't login as root so I can't change the root password.
mysql -u root -p
Enter password: <blank>
ERROR 1045 (28000): Access denied for user 'root'#'localhost'
(using password: NO)
When I try to set one like this:
mysqladmin -u root password 'newpass'
I get an error:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'#'localhost'
(using password: NO)'
As if there is a root password set.
I have also tried resetting the password using (described here)
/sbin/service mysqld start --skip-grant-tables
And then making:
mysql> UPDATE mysql.user SET Password=PASSWORD('newpass')
-> WHERE User='root';
ERROR 1142 (42000): UPDATE command denied to user ''#'localhost' for table 'user'
I even uninstalled mysql-server (using yum) and then reinstalled it but that did not help.
How do I force reset the root password?
One option is to save UPDATE mysql.user SET Password=PASSWORD('newpass') WHERE User='root'; into a file and then manually start mysqld with --init-file=FILENAME. Once the server starts, it should reset your password, and then you should be able to log in. After this, you should shut down the server and start it normally.
A little late to the game, but I had the same issue on a raspberry pi install and found out that it needs elevation. Adding a sudo to the front of the password change allowed it to work.
sudo mysqladmin -u root password 'newpass'
followed by an elevated sql access
sudo mysql -u root -p
If either are not run as sudo, it will fail.
The root user password is an empty string by default.
And (using password: NO) says that there is no password.
Do you try to login from another system? I imagine you can only login as root user locally.
I removed the MySQL installation and deleted the data files, and then reinstalled it.
Then I was able to set the root password. Once you set the root password to something. mysqladmin won't let you reset it if you don't know it.
To reset it, you've got to have ownership over how mysqld is executed, and feed it an init file to change the root password:
https://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html
This helped me on Windows with MySQL Server 5.6. Make sure you change the mysqld path to point to where you have installed MySql Server, for me it was "C:\Program Files\mysql\MySQL Server 5.6\bin\mysqld.exe":
Log on to your system as Administrator.
Stop the MySQL server if it is running. For a server that is
running as a Windows service, go to the Services manager:
From the Start menu, select Control Panel, then
Administrative Tools, then Services. Find the MySQL
service in the list and stop it.
If your server is not running as a service, you may need to use
the Task Manager to force it to stop.
Create a text file containing the following statements.
Replace the password with the password that you want to use.
UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;
Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.
Save the file. For this example, the file will be named C:\mysql-init.txt.
Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.
Start the MySQL server with the special --init-file option (notice that the backslash in the option value is doubled):
C:\> C:\mysql\bin\mysqld --init-file=C:\\mysql-init.txt
If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.
The server executes the contents of the file named by the --init-file option at startup, changing each root account password.
You can also add the --console option to the command if you want server output to appear in the console window rather than in a log file.
If you installed MySQL using the MySQL Installation Wizard, you may need to specify a --defaults-file option:
C:\> "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld.exe"
--defaults-file="C:\\Program Files\\MySQL\\MySQL Server 5.5\\my.ini"
--init-file=C:\\mysql-init.txt
The appropriate --defaults-file setting can be found using the Services Manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable field contains the --defaults-file setting.
After the server has started successfully, delete C:\mysql-init.txt.
http://docs.oracle.com/cd/E17952_01/refman-5.5-en/resetting-permissions.html
Remove the -p from your command. -p forces the prompt for password.
Use :
mysql -u root
This will resolve your problem.
Probably a bit late here , but here is what I did :
create file resetpass.sh which has :
UPDATE mysql.user SET Password=PASSWORD('newpassword') WHERE User='root';
# mysqld_safe --init-file=resetpass.sh
# service mysqld start --skip-grant-tables
# mysql -u root -p
Enter pass
mysql > change root pass ; flush privs;
quit
# restart mysql service
The MySQL version I was using was 5.1.73 under centos6
Try do this:
mysql -u root
and then:
mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass')
-> WHERE User='root';
mysql> FLUSH PRIVILEGES;
Worked fine for me!
According to the docs, in MySQL 5.7 the temp password gets put in /var/log/mysqld, but this is evidently not the case in 5.6.
With MySQL version 5.6 installed on RHEL 6.7, I finally found the temporary root password set during install was placed in the file /root/.mysql_secret.
open mysql
now enter the following commands :
use mysql;
update user set PASSWORD=password("updated password") where User='root';
flush privileges;
I tried to deploy web application on my server and I am getting this mysql database exception
Access denied for user 'root'#'localhost' (using password: YES) (Mysql::Error)
I tried to access the database from the command prompt using mysql -u root -p I am able to do all the database operations.
what is the error

You need to grant access to root from localhost. Check this ubuntu help
try using root like..
mysql -uroot
then you can check different user and host after you logged in by using
select user,host,password from mysql.user;
check you are putting blank space in password.
From my answer here, thought this might be useful:
I tried many steps to get this issue corrected. There are so many sources for possible solutions to this issue that is is hard to filter out the sense from the nonsense. I finally found a good solution here:
Step 1: Identify the Database Version
$ mysql --version
You'll see some output like this with MySQL:
$ mysql Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using EditLine wrapper
Or output like this for MariaDB:
mysql Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1
Make note of which database and which version you're running, as you'll use them later. Next, you need to stop the database so you can access it manually.
Step 2: Stopping the Database Server
To change the root password, you have to shut down the database server beforehand.
You can do that for MySQL with:
$ sudo systemctl stop mysql
And for MariaDB with:
$ sudo systemctl stop mariadb
Step 3: Restarting the Database Server Without Permission Checking
If you run MySQL and MariaDB without loading information about user privileges, it will allow you to access the database command line with root privileges without providing a password. This will allow you to gain access to the database without knowing it.
To do this, you need to stop the database from loading the grant tables, which store user privilege information. Because this is a bit of a security risk, you should also skip networking as well to prevent other clients from connecting.
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.
Now you can connect to the database as the root user, which should not ask for a password.
$ mysql -u root
You'll immediately see a database shell prompt instead.
MySQL Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
MariaDB Prompt
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
MariaDB [(none)]>
Now that you have root access, you can change the root password.
Step 4: Changing the Root Password
mysql> FLUSH PRIVILEGES;
Now we can actually change the root password.
For MySQL 5.7.6 and newer as well as MariaDB 10.1.20 and newer, use the following command:
mysql> ALTER USER 'root'#'localhost' IDENTIFIED BY 'new_password';
For MySQL 5.7.5 and older as well as MariaDB 10.1.20 and older, use:
mysql> SET PASSWORD FOR 'root'#'localhost' = PASSWORD('new_password');
Make sure to replace new_password with your new password of choice.
Note: If the ALTER USER command doesn't work, it's usually indicative of a bigger problem. However, you can try UPDATE ... SET to reset the root password instead.
[IMPORTANT] This is the specific line that fixed my particular issue:
mysql> UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';
Remember to reload the grant tables after this.
In either case, you should see confirmation that the command has been successfully executed.
Query OK, 0 rows affected (0.00 sec)
The password has been changed, so you can now stop the manual instance of the database server and restart it as it was before.
Step 5: Restart the Database Server Normally
The tutorial goes into some further steps to restart the database, but the only piece I used was this:
For MySQL, use:
$ sudo systemctl start mysql
For MariaDB, use:
$ sudo systemctl start mariadb
Now you can confirm that the new password has been applied correctly by running:
$ mysql -u root -p
The command should now prompt for the newly assigned password. Enter it, and you should gain access to the database prompt as expected.
Conclusion
You now have administrative access to the MySQL or MariaDB server restored. Make sure the new root password you choose is strong and secure and keep it in safe place.
I faced the same error after upgrading MySQL server from 5.1.73 to 5.5.45
There is another way to fix that error.
In my case I was able to connect to MySQL using root password but MySQL actively refused to GRANT PRIVILEGES to any user;
Connect to MySQL as root
mysql -u root -p
then enter your MySQL root password;
Select database;
use mysql;
Most probably there is only one record for root in mysql.user table allowing to connect only from localhost (that was in my case) but by the default there should be two records for root, one for localhost and another one for 127.0.0.1;
Create additional record for root user with Host='127.0.0.1' if it's not there;
SET #s = CONCAT('INSERT INTO mysql.user SELECT ',
REPLACE((SELECT GROUP_CONCAT(COLUMN_NAME)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'user' AND TABLE_SCHEMA = 'mysql')
,"Host","'127.0.0.1'"),
' FROM mysql.user WHERE User="root"');
PREPARE stmt FROM #s;
EXECUTE stmt;
Additionally to that you can execute mysql_upgrade -u -p
to see if everything is ok.
This error happens if you did not set the password on install, in this case the mysql using unix-socket plugin.
But if delete the plugin link from settings (table mysql.user) will other problem. This does not fix the problem and creates another problem. To fix the deleted link and set password ("PWD") do:
1) Run with --skip-grant-tables as said above.
If it doesnt works then add the string skip-grant-tables in section [mysqld] of /etc/mysql/mysql.conf.d/mysqld.cnf. Then do sudo service mysql restart.
2) Run mysql -u root -p, then (change "PWD"):
update mysql.user
set authentication_string=PASSWORD("PWD"), plugin="mysql_native_password"
where User='root' and Host='localhost';
flush privileges;
quit
then sudo service mysql restart. Check: mysql -u root -p.
Before restart remove that string from file mysqld.cnf, if you set it there.
#bl79 is the author of this answer, i've just reposted it, because it does help!
My application is using Mura CMS and I faced this issue. However the solution was the password mismatch between my mysql local server and the password in the config files. As soon as I synched them it worked.
I solved this problem by deleting the empty users creating by MySQL. I only have root user and my own user. I deleted the rest.
Update the empty password in the table mysql.user of mysql
use mysql;
select host,user,password from mysql.user;
update mysql.user set password = PASSWORD('123456') where password = '';
flush privileges;
Update user table in mysql DB. And set some password where it is blank, i was using root user so i set password for root user.
update mysql.user set password = PASSWORD('123456') where password = '';
flush privileges;
And then again tried from ATG CIM by providing password and it worked fine.

I got this problem today while installing SugarCRM (a free CRM).
The system was not able to connect to the database using the root user. I could definitively log in as root from the console... so what was the problem?
I found out that in my situation, I was getting exactly the same error, but that was because the password was sent to mysql directly from the $_POST data, in other words, the < character from my password was sent to mysql as < which means the password was wrong.
Everything else did not help a bit. The list of users in mysql were correct, including the anonymous user (which appears after the root entries.)
I googled a lot but did not find a definite answer to my problem. I used KeyPass to generate a strong password and could use it successfully on mysql workbench to connect but not from the command line. So I changed the psw to an easy one and it worked on the command line. I have managed to create a strong password that was able to connect from the terminal. So my advise is, try with an easy password first before trying all kind of things.
I was running UTs and I started receiving error messages. I am not sure what was the problem. But when I changed my encoding style in INTELLIJ to UTF8 it started working again.
access denied for user 'root'#'localhost' (using password yes)
hibernate
this is my URL
db.url=jdbc:mysql://localhost:3306/somedb?useUnicode=true&connectionCollation=utf8_general_ci&characterSetResults=utf8&characterEncoding=utf8
Add a user option in msyql.
GRANT PROXY ON ''#'' TO 'root'#'localhost' WITH GRANT OPTION;
and this link will be useful.
I have spent hours just trying to set up MySQL and still no success(on windows). I am starting to doubt my very name.
When I try to configure it says:
"The security settings could not be applied. Error Number 1045. Access denied for user 'root'#'localhost' (usin passwrd: NO)
And before it kept rejecting my password.
http://www.wampserver.com/en/download.php
Use it, love it, stop wasting time and get programming!
OR YOU CAN TRY THIS....
If you actually have set a root password and you've just lost/forgotten it:
Stop MySQL
Restart it manually with the skip-grant-tables option: mysqld_safe --skip-grant-tables
Run the MySQL client: mysql -u root
Reset the root password manually with this MySQL command: UPDATE mysql.user SET
Password=PASSWORD('password') WHERE User='root';
Flush the privileges with this MySQL command: FLUSH PRIVILEGES;
From http://www.tech-faq.com/reset-mysql-password.shtml
MySQL - ERROR 1045 - Access denied
I had this (frustrating) issue as well.
What I did was:
Uninstall MySQL
Delete the folder C:\ProgramData\MySQL\
Install MySQL again
Hope it works for you as well.
