I'm having a weird problem where I cannot login to my MySQL server with sudo as root on a ubuntu 19.10 server. I want to be able to reset my root password.
The error message I got was:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO)
Anyone had similar problems? Thanks!
Ok - so I solved this problem myself.
The correct way of resetting the root password for mysql is to:
Stop all mysql server sessions.
Start mysqld manually using - this basically tells MySQL to skip any credentials check and allow anyone to login, hence you want to skip-networking to avoid network users.
sudo mysqld --skip-grant-tables --skip-networking
Use this to login as root:
sudo mysql -u root
In the mysql prompt, do:
FLUSH PRIVILEGES;
SET PASSWORD FOR root#'localhost' = PASSWORD('password');
FLUSH PRIVILEGES;
Stop mysqld and restart mysql normally (you may need to kill the mysqld process).
In my case, there was some problems with the installation and the /var/run/mysqld folder was not correctly set up. It may be a bug with MySQL and it was not properly reported.
After creating the folder with the correct setmod (user:group is mysql:mysql) mysqld runs without any problem.

I enter mysql -u root -p and put in my password and get this error, I have uninstalled and reinstalled mysql and changing the password for root but still get this message.
I have looked and looked for solutions but nothing seems to work.
I am trying to enter mysql through my terminal, instead I get get the error above and can't get into mysql even after uninstalling and reinstalling it.
Usually this means that you are using the wrong credentials to connect, try to consult consult the general log file /var/log/mysqld.log to copy the initialization password.
if that doesn't work you can try this approach:
check if MySQL is installed and running on your system sudo service mysql status
Reset the root password:
stop the server: sudo /etc/init.d/mysql stop
start the server in safe mode: sudo mysqld_safe --skip-grant-tables &
try to connect: mysql -u root
reset the root password: UPDATE mysql.user SET authentication_string=PASSWORD('newpassword'), password_expired='N' WHERE User='root';
flush privileges: FLUSH PRIVILEGES;
quit the server: quit
stop the safe mode server: sudo /etc/init.d/mysql stop
now you can start the MySQL server again: sudo /etc/init.d/mysql start
Use the correct credentials to connect (with the new password)

I've searched a lot but nothing works for me.
I have a fresh installation of a LAMP server, installed via tasksel command.
My system runs php 7.4 and MySql 8
For some reason root user (that in my case is called phpmyadmin, by default) has no privileges on the DBs.
I can log in, so I'm sure the password is correct, but I cannot create a Database.
$ mysql -u phpmyadmin -p
mysql > create database test;
Access denied for user 'phpmyadmin'#'localhost' to database 'test'
EDIT
As suggested, here's the output of
mysql> SELECT name, Create_priv FROM mysql.user;
SELECT command denied to user 'phpmyadmin'#'localhost' for table 'user'
NEW EDIT
I tried to access without the password, following the guide reported here:
...
No results for me :(
Stop the MySQL Server: sudo /etc/init.d/mysql stop (OK)
Start the mysqld configuration: sudo mysqld --skip-grant-tables
output:
[2] 2345
[1] Exit 1 sudo mysqld --skip-grant-tables
Run: sudo service mysql start
output
[2]+ Exit 1 sudo mysqld --skip-grant-tables
It seems to exit with errors... Am I wrong?
I also tried to login in that situation, but I receive this message "ERROR 1698 (28000) Access denied for user 'root'#'localhost'"
If I try my phpmyadmin user, the message is "ERROR 1045 (28000): Access denied for user 'phpmyadmin'#'localhost' (using password: NO)"

I followed the steps reported here
How to reset or change the MySQL root password?
I had to use MD5() instead of PASSWORD() because it's now deprecated.
There's still something wrong.
Now I can access the database with no privileges and set/change my password.
Then I can flush all privileges.
Then I try...
mysql -u root -p
I enter my new password...
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
I can still log in with the user set in phpMyAdmin, but there are still no privileges for me.
I also reinstalled MySql server.
I remember I had a similar problem last time I installed an old Linux Virtual Machine, but I solved that issue easily. Now I'm wondering what's wrong :(
SOLVED
I reinstalled my virtual machine and installed manually both php and mysql server.
To be sure to set privileges in the right way I followed this small guide... maybe helpful for someone.

Bye!
I understand that this is the safest way to change or reset mysql root password. I'm doing it because 8 times out of 10 the installation program won't prompt me for a root password.
So I run commands:
sudo /etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables &
sudo mysql -u root
use mysql;
Then, depending on your version of mysql or maria you're using you type:
update user set password=PASSWORD("mynewpassword") where User='root';
or
ALTER USER 'root'#'localhost' IDENTIFIED BY 'MyNewPass';
In my case I typed the first one. Then I refresh privileges by:
flush privileges; and then I exit out of mysql by typing: quit.
At this point everything went well. Then I restart mysql server by:
sudo /etc/init.d/mysql start
I get "OK" from the terminal. However, when I attempt to log in as root
I get pleasant error message saying:
ERROR 1698 (28000): Access denied for user 'root'#'localhost'
I'm 100% confident that I'm typing correct password. Why is this happening ?
Problem resolved by backing up all important data and reinstalling the operating system. As turned out I had some broken packages that affected how mysql authentication worked. Standard steps to fix broken packages was no use so I wiped out HDD and started over.
MySQL was installed without any hiccups and was even prompted for a root password to be set. Now MySQL authentication works like a charm.
Try this out :- It Works for me..!!
Stop the MySQL server process.
service mysql stop
Start the MySQL (mysqld) server/daemon process with the –skip-grant-tables option so that it will not prompt for password.
mysqld_safe --skip-grant-tables > /dev/null 2>&1 &
Connect to mysql server as the root user. And Setup new mysql root account password.
mysql -u root -e "use mysql; update user set password=PASSWORD('NEW-PASSWORD') where User='root'; flush privileges;"
Exit and restart the MySQL server.
service mysql restart
Note: You may need to wait after mysqld_safe command, before you can run subsequent mysql command.
Now run :- mysql -u root -p
I just reinstalled MySQL using brew on my mac.
As far as I can see everything works fine, but I cannot change my root password.
When trying I'm getting this error message:
mysql -u root
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: NO)
The common way to solve this seems to use (several answers on stack overflow suggest using this):
sudo mysqld_safe --skip-grant-tables
2017-05-19T11:54:35.6NZ mysqld_safe Logging to '/usr/local/var/mysql/mac.err'.
2017-05-19T11:54:35.6NZ mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
2017-05-19T11:54:35.6NZ mysqld_safe mysqld from pid file /usr/local/var/mysql/mac.pid ended
I stopped the server before executing the command. But this solution does not work for me.
There is also no entry in the error log:
/usr/local/var/mysql/mac.err
I read also about using mysql_secure_installation but there I get just the same error message as when using mysql -u root.
As I mentioned above, I tried already to just uninstall and reinstall it again, but obviously some data remained. So is there maybe any way to manually delete or reset these files?
Solution by OP.
It turned out that:
mysql.server start --skip-grant-tables
(not sure if sudo is necessary)
works for me.
The access denied is because you're not specifying the -p switch
If you know the old password then maybe login to MySql and change it as:
1).login to MySql 2).change to the correct db 3) change the passwd and flush
mysql -u root -p
mysql> use mysql;
mysql> update user set password=PASSWORD("newpass") where User='ENTER-USER-NAME-HERE';
mysql> flush privileges;
mysql> quit
Also, the following works in Linux/Unix systems but i haven't tested it on Mac (may work if you have the clients installed)
mysqladmin -u root -p oldpassword newpass

I using mariadb and my mysql root user lost all of privelages. so everything gives me the "access denied" now.
I tried to reinstall mysql but it's looks like the configure files not deleted.
how can I fix it when I can't access to mysql table and even can't have another fress install.
by the way I using ubuntu 16.04 and according to this question
How do I restore the MySQL root user's privileges?
I think I can't do any thing except remove mariadb completely with all configure files.
------------------update------------------
I have no problem with my password, the problem is my root user has no privelages.
please don't send solutions about changing password
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;
