Before you begin installation, make sure you are logged in as root or a non-root user account with sudo privileges.

Step 1 – Install Apache

By default, Apache package comes with Ubuntu repository. At first, you have to update the package index and then install apache2 package:

Once Apache is installed and it will start apache2 service automatically.

Step 2 – Adjusting the Firewall

After Apache installation make sure that your firewall allows HTTP and HTTPS traffic. You can get list of ufw profile list by typing :

sudo ufw app list

Available applications:
   Apache
   Apache Full
   Apache Secure
   OpenSSH

Allow incoming HTTP and HTTPS traffic for this profile:

sudo ufw allow in "Apache Full"

Step 3 – Verifying Apache Installation

At this point, your Apache web server should be up and running. To verify that Apache works correctly, execute below command:

sudo systemctl status apache2

It will show you output like below :

● apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
