How to Install Apache Httpd Web Server on Linux

Apache HTTP Server, often referred to as Apache or httpd, is a widely used open-source web server software. It is known for its flexibility, reliability, and ease of use, making it an ideal choice for hosting websites on Linux systems.

In this guide, we will walk through the steps to install Apache HTTP Server on a Linux system. By following these steps, you will set up a functional Apache web server that can host your website or web application. The goal is to have a running Apache web server accessible via a web browser.

Step 1: Update your system

Before installing the Apache HTTP Server, ensure that your system’s package list and installed packages are up to date:

sudo apt update && sudo apt upgrade

This command will work for Debian-based systems like Ubuntu. For other Linux distributions, replace apt with the appropriate package manager, such as yum for RHEL/CentOS, or dnf for Fedora.

Step 2: Install Apache HTTP Server

Now that your system is up to date, install the Apache HTTP Server package:

For RHEL-based systems (RHEL, CentOS):

sudo yum install httpd

For Fedora:

sudo dnf install httpd

For Debian-based systems (Ubuntu, Debian):

sudo apt install apache2

Wait for the installation process to complete.

Like that:

Step 3: Start and enable the Apache service

Once installed, start the Apache HTTP Server service and enable it to start automatically at boot:

For Debian-based systems (Ubuntu, Debian):

sudo systemctl start apache2
sudo systemctl enable apache2

For RHEL-based systems (RHEL, CentOS) and Fedora:

sudo systemctl start httpd
sudo systemctl enable httpd

Step 4: Configure firewall settings

To allow incoming HTTP and HTTPS traffic, update your firewall settings:

For Debian-based systems (Ubuntu, Debian):

sudo ufw allow 'Apache'

For RHEL-based systems (RHEL, CentOS) and Fedora:

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

Step 5: Verify the Apache installation

To verify that the Apache HTTP Server is running, open a web browser and visit your server’s IP address or domain name:

http://your_server_ip_or_domain_name

You should see the Apache default welcome page.
