How to reload nginx configuration without restarting the service?

To reload the Nginx configuration without restarting the service, you can use the nginx -s reload command or use the systemctl reload nginx command.

Here’s how to reload the Nginx configuration without restarting the service on Ubuntu:

1. Open a terminal and log in as root or use sudo before the command.
2. Type nginx -s reload or systemctl reload nginx and press enter.
3. Wait for the command to complete, and the Nginx service should reload the updated configuration without interruption to current sessions.

Alternatively, you can use the command service nginx reload or /etc/init.d/nginx reload to achieve the same result.

It’s important to note that reloading the Nginx configuration without restarting the service requires that you have made changes to the configuration file. If you have not made any changes, then reloading the configuration will have no effect.

Additionally, if there are any errors in the updated configuration file, the Nginx service may fail to reload properly. In such cases, it’s important to troubleshoot and fix any errors in the configuration file before attempting to reload the service.
