I'm having a bad day trying to find the reason why this bug is occurring to me.
when I run the express.js app (using pm2) it makes MySQL 5.7 server stop and when I try to restart the MySQL server it outputs an error.
Bear in mind that the express.js app is running on port 80 and MySQL is running on port 3306. and that the express.js app is not trying to talk or connect to MySQL in any ways so they shouldn't interact with each other.

Could you provide the logs from mysql logs? if it's using the default settings, it will be in /var/log/mysq/

I installed MySql 5.7 for work, now I got an active MySql server running on standart port 3306, that I can't terminate.
I tried service mysql stop and service mysqld stop. No active processes as well.
This is the output of service mysql status :

mostly other service is running on the same port (3306) ,
try
netstat -pnltu | grep -i "3306"
it will show all services running on that port , if there are any , just end it and restart your Mysql server
I tried to reinstall MySQL and now it doesn't even start, and if I go to "messages" it says this
Jul 23 11:04:27 systemd: Starting MySQL Server...
Jul 23 11:04:29 systemd: mysqld.service: main process exited, code=exited, status=1/FAILURE

Jul 23 11:04:29 systemd: mysqld.service failed.
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

how do I fix this?
I just upgraded my RHEL system from 6.7 to 7.2, and am having issues starting up MySQL again.
When running:
# systemctl start mysqld
I get this error:
Job for mysqld.service failed because the control process exited with error code.
See "systemctl status mysqld.service" and "journalctl -xe" for details.
systemctl status tells me the following:
● mysqld.service - SYSV: MySQL database server.

Active: failed (Result: exit-code) since Tue 2017-05-02 10:00:52 CDT; 59s ago

I don't really know what any of this means, but I did have a successfully running MySQL server before the server had an OS upgrade.
Turns out I was getting this error because I hadn't created the necessary logging directory in:
/var/run/mysqld
and given it the proper permissions.
Looking at the log file in /var/log/mysqld.log led me to the issue.
