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.
