nginx won't restart, apache2 starts running now and then (automatically)

Question

I have a VPS running my nodeJS app, with Nginx as reverse proxy. The VPS has installed as default Apache. Often my app stops working, i check my vps through ssh and i try to restart nginx:

 service nginx restart

But i got the error:

Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

Looking for a solution in Stack Overflow i found this post: Nginx: Job for nginx.service failed because the control process exited where an answer says that i need to stop apache, so i write in console:

 sudo killall apache2 service nginx restart

And then works fine.? But for some reason apache2 starts running on its own now and then? Is there a way to fix this.? Thanks in advance.

Answer 1

It sounds like you needs to disable the apache2 service and enable the nginx service.

systemctl stop apache2
systemctl disable apache2

systemctl enable nginx
systemctl start nginx
