How to Modify MySQL User Root Password in Linux

Pace 1: Log in every bit the MySQL User

When you kick into your Linux installation, make sure y'all're logged in as the aforementioned user that ordinarily runs MySQL. Although you tin can log in as root, once y'all start the MySQL server, make sure you start information technology with the --user=mysql pick.

Otherwise, the organization may create files endemic by the root user, which can crusade problems.

Step two: Observe the .pid File for the MySQL Service

The next step is to discover the .pid file for the MySQL service.

Most systems store them in /var/lib/mysql/, /var/run/mysqld/, or /usr/local/mysql/information/ path. The filename usually starts with mysqld (or your arrangement's hostname) and ends with the .pid extension.

Footstep iii: Kill the mysqld Process

Before yous create a new root password, stop the MySQL server. To impale the mysqld process, open a control line, and run the following:

          kill `cat /mysql-information-directory/host_name.pid`        

Replace mysql-information-directory/host_name.pid with the filename you found in the previous step. Ensure to specify the whole path to the file. Also, make sure to utilise the dorsum-tick cardinal (ordinarily above the tab key) and not a unmarried-quote mark in the first of the command.

The command volition work for the machine you're currently using. If you're connecting to a different organization, supplant localhostwith the appropriate hostname.

iii. Save the file to habitation/me/mysql-init.

Footstep five: Restart the MySQL Server and Apply the New Password

To apply the changes to the password, restart the MySQL server by running the following command in the final:

          mysqld --init-file=/home/me/mysql-init &        

This launches MySQL, and apply the text-file password alter. Depending on how you beginning your server, you may need to add other options (such as --defaults-file earlier the init command.)

Footstep six: Cleaning Up

Lastly, log into your MySQL server using the root business relationship, and verify the new countersign works. Then, delete the file you created in Step 4.

          mysqld --init-file=C:\\mysql-init.txt        

Note that at that place are ii slashes afterwards the C: prompt.
Too, if you lot chose a different filename in Step ii, utilize that proper noun later on the double slash.

Step 6: Clean up

At present, you tin log into your MySQL server as root using the new password.

Double-bank check to brand sure it works. If you have unique configuration options (such as launching MySQL with a --defaults-file option), get ahead and do so.
