nginx -t

This command checks the syntax of the nginx configuration file (usually located in /etc/nginx/nginx.conf ). If the configuration file is correct, the following message will be displayed:

 <code>nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful</code>

nginx -V

This command displays the nginx version and other information about its compilation options and other information.

service nginx status

 <code>nginx is running (pid 12345)</code>

ps -ef | grep nginx

This command displays all running nginx processes in the system. The output is similar to:

 <code>root 12345 15122 15:02 ? 00:00:05 nginx: master process /usr/sbin/nginx -g daemon on; master_process on; root 12346 15125 15:02 ? 00:00:00 nginx: worker process</code>

netstat -nlp | grep nginx

This command displays the port and address of nginx listening. The output is usually as follows:

 <code>tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN tcp 0 0 :::80 :::* LISTEN</code>
