How can the port number of nginx be changed on Linux?

To change the port number of Nginx, you need to modify the Nginx configuration file.

Firstly, open the configuration file of nginx using a text editor such as vi or nano. Depending on the Linux distribution, the location of the configuration file may vary. Typically, the configuration file can be found at /etc/nginx/nginx.conf or /etc/nginx/conf.d/default.conf.

Next, locate the “listen” command in the file, which is used to specify the port number to listen on. Change it to the desired port number.

For example, change the port number to 8888:

listen 8888;

Save and close the file.

Next, restart the nginx service to apply the configuration. You can use the following command to restart the nginx service:

sudo systemctl restart nginx

If your Linux distribution does not use systemd as a service manager, you can restart the nginx service by using the appropriate command.

After completing the above steps, nginx will start listening on the new port number you specified.
