sudo apt-get install yum

Install yum if needed, but my case, eventually I didn’t, but for future reference…

To start installing, run this command:

sudo apt-get install mysql-server

During the installation, the root password is being asked:

sudo netstat -tap | grep mysql

After the installation, type this to prevent autostart the server
Then, showing following output:
From the leftside:
———————————————————
[protocol][local address][outer address][status]

tcp        0      0 localhost:mysql         *:*                     LISTEN      3978/mysqld

To start terminal, type this, then enter password:

$ mysql -u root -p

Terminal started:
