Stop mysql from running at boot time?

To prevent mysql from starting on boot:

  1. Open the terminal: Ctrl+Alt+T
  2. Open the mysql.conf file: nano /etc/init/mysql.conf
  3. Comment out the “start on” line near the top of the file, the “start on” might be spread across two lines, so comment out both. (comment adding # at the beginning)

If you want to manually start mysql, use the following command:

service mysql start
