What Is Apache?
Apache is a free and open-source software that allows users to deploy their websites on the internet. It is one of the oldest and most reliable web server software maintained by the Apache Software Foundation, with the first version released in 1995.
The job of a web server is to serve websites on the internet. To achieve that goal, it acts as a middleman between the server and client machines. It pulls content from the server on each user request and delivers it to the web.
Here are some of the reasons why Apache is so popular:
- It is free and open-source software.
- It is very reliable and stable.
- It is very scalable and can handle a large amount of traffic.
- It is very extensible and can be customized to meet the needs of different websites.
If you are looking for a reliable, scalable, and extensible web server, Apache is a great choice.

Public domain example
Configure firewalld to Allow Apache Traffic
Normal web traffic uses the http protocol on Port 80, while encrypted web traffic uses the https protocol, on Port 443.
Modify your firewall to allow connections on these ports
http
sudo firewall-cmd ––permanent ––add-port=80/tcp
sudo firewall-cmd ––permanent ––add-port=80/udp
https
sudo firewall-cmd ––permanent ––add-port=443/tcp
sudo firewall-cmd ––permanent ––add-port=443/tcp
Now reload the firewall
firewall-cmd –reload or sudo firewall-cmd ––reload
