How to Install MySQL 5.5 on Ubuntu Server 12.04 LTS

For this how to, I am going to document how to install MySQL on an installation of Ubuntu 12.04 LTS

Installing it is a very straight forward and quick process and I prefer to use the terminal. If you are running a GUI, you can also install it through the Ubuntu sofware centre. Typically available with the Ubuntu desktop version.

If you are running the desktop version of Ubuntu, fire up a terminal either by clicking on the icon or by pressing Ctrl + Alt + T

It’s a good idea to update your server package cache before proceeding.

[sourcecode language=’sql’]
sudo apt-get update
[/sourcecode]

Then, run
[sourcecode language=’sql’]
sudo apt-get install mysql-server-5.5
[/sourcecode]

Once you have entered the password for sudo access, the installation will proceed. The only thing it will ask you is what to set the root password for MySQL as. You SHOULD set a password up, don’t leave it blank with the intention of doing it later. I would recommend you find a decent password generator too.

Once installation has completed, you just need to check that mysql is running. To do this, run

[sourcecode language=’sql’]
sudo netstat -tap | grep mysql
[/sourcecode]

If MySQL is running you will see output similar to the following:

tcp  0  0 localhost:mysql  *:*  LISTEN  2480/mysqld

Now test that you can login

[sourcecode language=’sql’]
mysql -uroot -p
[/sourcecode]

Type in the root password directly after the -p switch without spaces.

You can also view what packages have been installed by typing:

[sourcecode language=’sql’]
dpkg -l | grep mysql
[/sourcecode]

Which should return output similar to the following:
