You often need to restart apache 2 or restart nginx web server Maybe you may have increased the php max upload file size limit but still, your changes have not come to action so you need to restart the web server so that it will load the updated configuration files. Therefore today I will tell you all that you need to know about restarting Apache 2 and Nginx.

Firstly for restarting web server you either need access via SSH or need have physical access to the machine. Basically, you need to have access to the server terminal so that you can run the required commands. So if you don’t have access to your server’s terminal and then it would not be a great idea to read this post any further get access to the terminal and come back here so that you can follow the instructions further and restart your web server.

Okay, so now that you are reading further I believe that you have access to the terminal and all set for restarting your Apache 2 or Nginx web server.

Let’s start with the most popular web server which is Apache 2.
