Ubuntu mysql install

You can check whether mysql has been installed in Ubuntu system with the ps command or dpkg command to check the installed package.

Check mysql daemon using ps command:

luzar@ubuntu:~$ ps aux | grep mysql

luzar@ubuntu:~$

So I already have mysql installed during installation. If you don't have mysql in your Ubuntu server, you can install it using apt-get command. If you already configured your Internet connection, then issue the apt-get command like in the example below:

luzar@ubuntu:~$ apt-get install mysql-server-5.0

The apt-get tool will ask you to confirm the mysql installation, and you need to answer Y (yes).

That's all you need to do to have mysql installed in your Ubuntu system.
