Have you used some version of the 'ps' command to look at the process list and verify that nginx is running?

If you've tried to start nginx, but it doesn't appear in the process list, have you looked at the startup log files that nginx likely wrote somewhere in /var/log/nginx/<something> or /var/log/nginx.log ? There may also be error messages that were captured by your system's service/init. You don't say what OS/distro or version you're using, so we can't provide any kind of useful suggestion on what the command might be to look at those logs. A lot of recent Linux distros would use "systemctl status -l nginx.service" or something with "journalctl".

If nginx *is* running, have you used a network port tool to see if it's listening on the network? Older systems would use "netstat -an" and look for the ports where it would be listening and try match that to process IDs, whereas newer systems could use "sudo ss -ltnp" to get similar but more detailed information.
