Knowing if Nginx is running is important for keeping a reliable web server. Checking the server's status helps find potential issues and keeps websites and applications running well.
Methods to Check Nginx Status

The command line offers ways to check if Nginx is running:
- Service status command: Use
sudo systemctl status nginxorsudo service nginx statusto view Nginx's current state. - Process checking command: Run
ps aux | grep nginxto list Nginx processes. - Port verification command: Execute
sudo netstat -tulpn | grep nginxto see if Nginx is listening on its default port (usually 80).
Tip: Quick Nginx Status Check
Combine multiple commands for a quick status overview:
echo "Nginx Status:" && sudo systemctl is-active nginx && echo "Listening Ports:" && sudo ss -tulpn | grep nginxChecking Web Server Response
You can verify Nginx's status by checking its response:
- Browser-based verification: Open a web browser and enter your server's IP address or domain name. If Nginx is running, you'll see the default welcome page.
- Using curl command: In the terminal, type
curl -I http://localhostorcurl -I http://your_server_ip. This will show the HTTP header information if Nginx is active.

Inspecting Nginx's configuration can provide insights into its status:
- Checking configuration file: Review the main Nginx configuration file with
sudo nano /etc/nginx/nginx.confto ensure it's set up correctly. - Verifying log files: Check Nginx's error logs with
sudo tail -f /var/log/nginx/error.logto see any recent issues or confirm normal operation.
