How to resolve the below error on Ubuntu 16.04

Check your MYSql status via this command :-

sudo systemctl status mysql

If it is not running, then use either sudo systemctl start mysql or a shorter command sudo /etc/init.d/mysql start

sudo systemctl status mysql
● mysql.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)

I AM GETTING THE ABOVE ERROR.

sudo systemctl start mysql
Failed to start mysql.service: Unit mysql.service not found.
