Installing MySQL in Ubuntu Linux is very easy with apt-get command. Open the terminal and type
apt-get install mysql-server
During the installation Process You will be asked to enter a password for the MySQL root user. Make sure you enter a strong password for root user (You can skip this step by leveling the password field empty. But then root can log into MySQL Server without a Password which means a big security hole, even though we can fix it later).

Remove anonymous users – During the installation, anonymous user was created for testing purpose and you should remove them before you move your database server to production environment.
Disallow root login remotely – It is better if you disable root login remotely, which means the MySQL root user cannot log into the database server from a remote computer. I would recommend to say yes.
Remove test database and access to it – By default, there is a database called 'test' and anyone can access the test database. Like anonymous users, This also created for testing purpose. This Also Should remove before moving to the production environment.
Reload privilege tables – After all above configuration you should Reload privilege tables in order to configurations to be effected, So say yes.

mysql -u root -p
Type exit or Press CTRL + C from your keyboard to exit from the console.
