Step – 1. Update System:

Using the following command, you have to update your Ubuntu system before installing the Apache web server.

$ sudo apt update

Step – 2. Install Apache Server:

After update completion, you need to execute the following command to install the latest version of Apache Server.

$ sudo apt install apache2

Do you want to continue? [Y/n]

When you execute the installing command, the server will prompt you to “Do you want to continue?” you have to type “Y” and hit enter on the keyboard.

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:

root@PRONAY-PC:~# sudo service apache2 status
 * apache2 is not running
root@PRONAY-PC:~#

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:

root@PRONAY-PC:~# sudo service apache2 status
