What do you do if your database server is down? Well, you can certainly reboot the server. That might solve the problem, but I rather restart the database first before doing something as drastic as rebooting a server. There are instances were rebooting doesn’t always solve the problem if there’s an issue with the database. Now, most open-source blogs and web applications today use MySQL as their database of choice. So, here are instructions on how to start, stop and restart MySQL on Ubuntu and Debian-based systems.

Stop MySQL database

$ sudo /etc/init.d/mysql stop

Start MySQL database

$ sudo /etc/init.d/mysql start

Restart MySQL database

$ sudo /etc/init.d/mysql restart
