Note: These steps should only be used if the WHM interface can not be used to reset the password. Also, these steps are best performed by a qualified system administrator, and cPanel support staff are not able to perform these steps for you.
This article walks you through manually resetting the MySQL root password in the event that the password in
/root/.my.cnf becomes desynced.
- Log in to WHM, select Service Manager under the 'Service Configuration' section, and disable monitoring for the MySQL service.
- Connect to the server via SSH as the root user.
- Stop the MySQL service:
- Create a text file in
- Add the following text to the file, where MyNewPass represents the password you would like to use:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
- Update the password in
/root/.my.cnfto the password used in this statement:
[root@server]# grep -i pass /root/.my.cnf password="MyNewPass"
- Change the ownership of the file to ensure there are no issues reading the file:
chown -v mysql. /var/lib/mysql/mysql-init
- Start MySQL manually using this command:
mysqld -u mysql --init-file=/var/lib/mysql/mysql-init &
- Now that the password has been updated, shut down MySQL safely using this command:
- Remove the init file:
/bin/rm -vi /var/lib/mysql/mysql-init
- Restart MySQL normally:
- In the WHM interface, re-enable MySQL service monitoring in Service Manager >> Service Configuration.
Note when using MySQL 5.7
It may be necessary to use the following statement in place of the ALTER statement shown above:
SET authentication_string = PASSWORD('MyNewPass'), password_expired = 'N'
WHERE User = 'root' AND Host = 'localhost';
