Setting Up Apache Server on Linux

Now that we’ve covered the basics let’s get started with installing Apache Server on Linux.

Step 1: Update System Packages

Before installing any new software on your Linux system, it’s good practice to update your system packages. Use the following command to update packages:

Command	Description
sudo apt update	Updates package lists for Ubuntu based system.
sudo yum update	Updates package lists for CentOS based system.

Step 2: Install Apache Server

Once you have updated your system packages, you can proceed to Apache Server installation. Use the following command for the installation:

Command	Description
sudo apt install apache2	Installs Apache2 on Ubuntu based system.
sudo yum install httpd	Installs Apache2 on CentOS based system.

Step 3: Verify Apache Installation

After installation, you can verify the Apache installation by checking the Apache version:

Command	Description
apache2 -v	Displays the Apache version for Ubuntu based systems.
httpd -v	Displays the Apache version for CentOS based systems.

Step 4: Configure Firewall

Most Linux distributions come with a built-in firewall, which by default does not allow incoming traffic to Apache. You must allow Apache through the firewall before accessing it through a web browser.

Use the following commands to allow Apache through the firewall:

Command	Description
sudo ufw app list	List the available firewall profiles on Ubuntu based systems.
sudo firewall-cmd --list-all	List the available firewall profiles on CentOS based systems.
sudo ufw allow 'Apache'	Allows all Apache traffic on Ubuntu based systems.
sudo firewall-cmd --add-service=http --permanent	Allows all Apache traffic on CentOS based systems.
sudo firewall-cmd --reload	Reload the firewall to apply the changes on CentOS based systems.

Step 5: Start Apache Server

Now that you’ve got Apache installed and properly configured, you can start the Apache service:

Command	Description
sudo systemctl start apache2	Starts the Apache service on Ubuntu based systems.
sudo systemctl start httpd	Starts the Apache service on CentOS based systems.
sudo systemctl enable apache2	Enables the Apache service to start automatically on Ubuntu based systems.
sudo systemctl enable httpd	Enables the Apache service to start automatically on CentOS based systems.

Step 6: Test Apache Server

Finally, let’s test Apache to ensure that it’s working correctly. Open your web browser and type in your server IP address or domain name. You should see the default Apache web page.
