apache:restart

The command "sudo apache2ctl restart" is used to restart the Apache HTTP server on a Unix/Linux system using the apache2 control script.

Here is a breakdown of the command:

• "sudo": It is a command that allows a user to run programs with the security privileges of another user, usually the superuser (root). It provides administrative privileges required to restart the Apache server.

• "apache2ctl": It is a command-line utility script used for controlling the Apache HTTP server. It provides various options to start, stop, restart, reload, and check the status of the server.

• "restart": It is an option used with the apache2ctl command that instructs Apache to stop all currently running instances of the server and then start a new one. This is useful when you want to apply any configuration changes made to the server or to fix any issues without completely stopping and starting the server.

By executing "sudo apache2ctl restart", you initiate the restart process to gracefully stop the running Apache server instances and then start a fresh instance with any updated configurations or fixes applied.
