I’m not able to start/reload my Ngnix server. Here are the error messages I get nginx.service is not active, cannot reload. 2025/04/02 11:30:29 [warn] 18813#18813: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1 nginx:…

The error looks like the process is not being started with the correct permissions. Are you using sudo to start the processes with root level privileges? It needs to be run with elevated permissions in order to be able to bind to port 80/443.

For NGINX failing to start, its pretty clear that the issue is that it does not have permiss…

And no, I didn’t add the complete nginx config. I’ll add it now

Yes, my Nginx path does exist in my system. Regarding the /run/nginx.pid file, do I have to edit it in order to start/run nginx server?

You don’t have to edit the file, but the user NGINX runs as needs to be able to create the file. Once you added a complete config, are you able to start NGINX?

Yes, I added a complete config. However I’m running into the same issue as before. I was able to get my nginx server running and get checkmk running too. I also was able to get checkmk to run behind nginx. However, I’m still having trouble with opening nginx/checkmk on the browser. I created a new…
