Unable to start mysql in ubuntu - mysql

Question

I have tried the following the code to restart the MySql services
sudo service mysql restart
got the following error
Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.
ubuntu#ip-172-31-52-10:~$ journalctl -xe
And the journalctl Log says
Unit mysql.service has begun starting up.
