Apache Server Raspberry Pi CentOS: An In-Depth Guide

Introduction

Greetings, fellow tech enthusiasts! If you’re here, you’re probably looking for a guide on how to set up an Apache server on a Raspberry Pi running CentOS. Look no further, because this article has got you covered!

Firstly, let’s break down what each of these components are.

Raspberry Pi

The Raspberry Pi is a credit-card sized computer that was created with the intention of promoting the teaching of basic computer science in schools. However, it has since gained popularity among hobbyists due to its affordability and versatility.

CentOS

CentOS is a Linux distribution based on Red Hat Enterprise Linux. It is known for its stability, security, and reliability, making it a popular choice for servers.

Apache Server

Apache is the most widely used web server software in the world. It is an open-source software that allows users to host and manage websites.

Now that we’ve covered the basics, let’s move on to the main topic: setting up an Apache server on a Raspberry Pi running CentOS.

Setting Up Apache on Raspberry Pi running CentOS

Before we dive into the specifics, it’s important to note that this guide assumes that you have already set up your Raspberry Pi with CentOS. If you haven’t done so yet, there are many tutorials available online that can guide you through the process.

Step 1: Installing Apache

The first step is to install Apache onto your Raspberry Pi. This can be done by running the following command:

Command	Description
$ sudo yum install httpd	Installs Apache web server

Once the installation is complete, start the Apache service by running the following command:

Command	Description
$ sudo systemctl start httpd	Starts Apache service

Step 2: Configuring Apache

Now that Apache is up and running, it’s time to configure it to suit your needs. The configuration file for Apache is located at /etc/httpd/conf/httpd.conf.

Here are some of the most commonly used configuration options:

DocumentRoot

This sets the directory where the website files are stored.

ServerName

This sets the domain name that the server uses.

DirectoryIndex

This sets the default page that is displayed when someone visits the website.

ErrorLog

This sets the location where error messages are stored.

CustomLog

This sets the location where access logs are stored.

After configuring the options to suit your needs, restart the Apache service by running the following command:

Command	Description
$ sudo systemctl restart httpd	Restarts Apache service
