Use nginx port

nginx is a high-performance web server with a default listening port of 80. Users can configure different listening ports by modifying the instructions in the nginx configuration file.

Modify the configuration file

The nginx configuration file is usually located in /etc/nginx/nginx.conf or /usr/local/etc/nginx/nginx.conf . To change the listening port, follow these steps:

1. Open nginx configuration file.
2. Find the listen command. This directive specifies the port to which nginx listens.
3. Change the port number in the listen directive.
4. Save changes and exit the configuration file.

Example

The following example changes nginx's listening port to 8080:

 <code>listen 8080;</code>

Reload nginx

After making changes to nginx configuration files, nginx needs to be reloaded for the changes to take effect. Nginx can be reloaded with the following command:

 <code>nginx -s reload</code>

Test changes

After reloading nginx, you can use the following command to check whether the port has been changed:

 <code>netstat -tulpn | grep nginx</code>

This command will display the port nginx is listening on.

Notice:

• Ensure that nginx users have access to the new port.
• Make sure the firewall allows connections to the port.
• If you change the listening port to an unprivileged port (e.g. 8080), nginx can be reloaded without root permissions.
