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 :
