How to check if Nginx in Linux is started

On Linux systems, you can use the following command to check whether Nginx is running:

 <code>systemctl status nginx</code>

After executing this command, you will see one of the following outputs:

If Nginx is started:

 <code>● 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 Fri 2023-02-10 16:23:48 PST; 4 days ago Main PID: 2964 (nginx) CGroup: /system.slice/nginx.service ├─2964 nginx: master process \/usr\/sbin\/nginx -g daemon off; └─2965 nginx: worker process</code>

If Nginx has stopped:

 <code>● nginx.service - A high performance web server and a reverse proxy server Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled) Active: inactive (dead) since Fri 2023-02-10 16:23:48 PST; 4 days ago Main PID: 2964 (code=exited, status=0/SUCCESS)</code>

Output explanation:

• Loaded: Indicates whether the nginx service has been loaded into the system.
• Active: Indicates whether the nginx service is currently running.
• Main PID: Displays the process ID of the nginx main process.
• CGroup: Instructs the control group to which the nginx process belongs.

If you see the "Active: inactive (dead)" message, it means Nginx has stopped. If you see the "Active: active (running)" message, it means Nginx is running.
