How to check if the nginx service is running?

To find out if nginx is running or not, run the following command

service nginx status

● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2018-02-14 23:53:45 CET; 6 days ago
  Process: 20659 ExecReload=/usr/sbin/nginx -g daemon on; master_process on; -s reload (code=exited, status=
 Main PID: 20569 (nginx)

           ├─20569 nginx: master process /usr/sbin/nginx -g daemon on; master_process on
           └─20663 nginx: worker process

You can also try:

ps waux | grep nginx

If it’s running, you should see

root      1663  0.0  0.2 125104  1492 ?        Ss   14:53   0:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process  on;
