How to check the running status of nginx

The methods to view Nginx running status are: use the ps command to view the process status; view the Nginx configuration file /etc/nginx/nginx.conf; use the Nginx status module to enable the status endpoint; use monitoring tools such as Prometheus, Zabbix, or Nagios.

How to view Nginx running status

Check the process status

The easiest way is to use the ps command to view the running status of the Nginx process:

 <code>ps aux | grep nginx</code>

This command lists all running processes, including Nginx processes. The output results will display information such as the process ID (PID), CPU and memory usage of the Nginx process.

View configuration file

The configuration file for Nginx is usually located in /etc/nginx/nginx.conf . You can open this file with a text editor such as vim or nano and view configuration information.

In the configuration file, you can find information about Nginx listening ports, virtual hosts, and error logs.

Using Nginx Status Module

The Nginx Status module allows you to view server status through an HTTP endpoint. To enable this module, add the following line in the Nginx configuration file:

 <code>load_module modules/ngx_status_module.so;</code>

And add a new Nginx server block to expose the state endpoint:

 <code>location /nginx-status { stub_status on; access_log off; }</code>

You can then view the status information of the Nginx server by browsing this endpoint:

 <code>http://<nginx_server_address>/nginx-status</nginx_server_address></code>

Use monitoring tools

There are also some monitoring tools that can help you view the running status of Nginx, such as:

• Prometheus
• Zabbix
• Nagios

These tools can periodically collect and display metrics for Nginx such as request rate, response time, and memory usage.
