👨‍💻 What is Apache Server

Apache is a free and open-source web server powering over 40% of all websites in the world, according to Netcraft. It’s easy to use and has many modules that make it a flexible web server for developers and administrators. Apache is compatible with most operating systems, including Linux, which is the focus of this article.

💻 Installing Apache Server on Linux

Before we start, ensure that you have access to the command line on your Linux server. The first step is to update the system to ensure all packages are up to date.

Operating System	Command
Ubuntu/Debian	sudo apt-get update
CentOS/RHEL/Fedora	sudo yum update

After updating, you can install Apache Server by running the following command in the terminal.

sudo apt-get install apache2

This command installs Apache server on Ubuntu or Debian Linux. However, if you’re using CentOS, RHEL or Fedora, run the command:

sudo yum install httpd

After installation, you can verify the Apache server by typing the server’s IP address or domain name in a web browser. If you see the “It works!” message, the installation was successful.

🚀 Starting and Stopping Apache Server on Linux

You can start, stop and restart Apache server using the following commands.

Command	Description
sudo systemctl start apache2 or sudo service apache2 start	Starts Apache server on Ubuntu/Debian
sudo systemctl start httpd or sudo service httpd start	Starts Apache server on CentOS/RHEL/Fedora
sudo systemctl stop apache2 or sudo service apache2 stop	Stops Apache server on Ubuntu/Debian
sudo systemctl stop httpd or sudo service httpd stop	Stops Apache server on CentOS/RHEL/Fedora
sudo systemctl restart apache2 or sudo service apache2 restart	Restarts Apache server on Ubuntu/Debian
sudo systemctl restart httpd or sudo service httpd restart	Restarts Apache server on CentOS/RHEL/Fedora

🗂️ Apache Server Configuration Files

Apache has many configuration files that determine how it responds to requests from users. The main configuration file is /etc/httpd/conf/httpd.conf on CentOS or /etc/apache2/apache2.conf on Ubuntu.

You can edit Apache configuration files to customize how it handles requests. However, before making any changes, ensure you back up the original file. You can use the following command to back up the file:

sudo cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bak (on CentOS)
sudo cp /etc/apache2/apache2.conf /etc/apache2/apache2.conf.bak (on Ubuntu)

After backing up, you can use any text editor, such as Nano or Vim, to edit the configuration file.

🔒 Setting Up SSL Certificate

An SSL certificate encrypts data transmitted between the server and client’s web browser, making it secure. You can install an SSL certificate on your Apache server by following these steps:

1. Ensure you have a domain name or IP address for the server
2. Generate a certificate signing request (CSR) with the server’s domain name or IP address
3. Request an SSL certificate from a trusted certificate authority (CA) such as Let’s Encrypt or Comodo
4. Install the SSL certificate on the server
5. Configure Apache to use the SSL certificate
