Overview:

The /usr/local/cpanel/scripts/securemysql script secures a cPanel account’s MySQL® configuration. To do this, the script performs the following actions:

• Confirms that MySQL’s root password exists.

• Changes the var/db/mysql and var/lib/mysql directories’ ownership to the mysql user.

• Removes the anonymous and remote root users.

• Removes the test database.

• Removes the database’s LOCK TABLES and TMP TABLES privileges.

To undo any changes that this script performs, create the /etc/securemysqldisable touch file.

Run the script

To use this script, run the following command as the root user:

/usr/local/cpanel/scripts/securemysql [arguments] [actions]
