If you are installing Apache Server on a cloud, it will install instantly, and if you are installing on a local machine, it will depend on your internet connection.

Step – 3. Check Apache Server Status:

After installing the Apache webserver, you have to perform one more step. In this step, you have to make sure that the HTTP server is running. So use the following command to check Apache server status.

$ sudo service apache2 status

Output:

[email protected]:~# sudo service apache2 status
 * apache2 is not running
[email protected]:~#

When you execute the service status command and show “* apache2 is not running,” then you have to run one more command to start the service.

$ sudo /etc/init.d/apache2 start

Or

$ sudo systemctl apache2 start

After using the starting command for the Apache server, you have to re-execute the service status command.

$ sudo service apache2 status

Output:

[email protected]:~# sudo service apache2 status
