Setup Apache Web Server Ubuntu: The Comprehensive Guide

Introduction

Welcome to our comprehensive guide on the topic of setting up Apache web server Ubuntu. The Apache web server is the most popular and widely used web server on the internet. Whether you want to host a website, set up a development environment, or build a cloud server, Apache is the go-to solution due to its reliability, security, and flexibility.

If you’re new to Ubuntu or simply want to set up an Apache server, this guide will walk you through all the steps required to get started. You’ll learn everything from installing and configuring Apache to creating virtual hosts and setting up SSL encryption. By the time you reach the end of this article, you’ll have a fully functional Apache web server running on your Ubuntu system.

Pre-requisites

Before we dive into the setup process, let’s discuss some of the pre-requisites required to follow this guide.

Pre-requisite

Setting up Apache Web Server Ubuntu – Step by Step

Step 1 – Update your system

The first step in setting up an Apache web server on Ubuntu is to update your system. Open the terminal and type the following command:

sudo apt update && sudo apt upgrade

This command will fetch the latest updates for your Ubuntu system and upgrade any existing packages if necessary.

Step 2 – Install Apache Web Server

Once you’ve updated your system, the next step is to install the Apache web server. Type the following command in the terminal:

sudo apt install apache2

After running the command, Ubuntu will fetch and install the Apache2 package along with its dependencies. Once the installation is complete, you can check if Apache is running by typing in your browser’s address bar:

127.0.0.1

You should see the default Apache web page:

Step 3 – Configure Firewall

By default, Ubuntu comes with UFW (Uncomplicated Firewall) enabled. You need to allow HTTP and HTTPS traffic through the firewall by typing:

sudo ufw allow 'Apache'

The command above will enable access to Apache for both HTTP and HTTPS traffic.

Step 4 – Create a Virtual Host

If you want to host multiple websites on your Apache server, you need to create virtual hosts. Virtual hosts enable you to run multiple websites on a single server with different domain names or IP addresses.

To create a virtual host, create a new file in the /etc/apache2/sites-available directory:

sudo nano /etc/apache2/sites-available/example.com.conf

Replace example.com with your own domain name.

Next, enter the following configuration:

 <VirtualHost *:80>ServerAdmin admin@example.comServerName example.comServerAlias www.example.comDocumentRoot /var/www/example.com/htmlErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost>

Save the file and exit the editor. Then enable the virtual host by typing:

sudo a2ensite example.com.conf

Finally, restart Apache:

sudo systemctl restart apache2

You can now access the virtual host by typing your domain name in the browser.

Step 5 – Secure the Server with SSL Certificate

If you want to secure your website with an SSL (Secure Sockets Layer) certificate, the next step is to install and configure SSL on your Apache server.

First, install the SSL module:

sudo apt install openssl

Then, generate a self-signed SSL certificate:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/example.com.key -out /etc/ssl/certs/example.com.crt

Note: Replace example.com with your domain name.

Next, configure Apache to use SSL by typing:

sudo nano /etc/apache2/sites-available/example.com.conf

Insert the following configuration within the VirtualHost block:

SSLEngine onSSLCertificateFile /etc/ssl/certs/example.com.crtSSLCertificateKeyFile /etc/ssl/private/example.com.key

Save the file and then restart Apache:

sudo systemctl restart apache2

You can now access the website using HTTPS in the browser.

Step 6 – Install PHP

If you want to use PHP (Hypertext Preprocessor) on your Apache server, you need to install it. To install PHP, type:

sudo apt install php libapache2-mod-php

Once PHP is installed, restart Apache:

sudo systemctl restart apache2

Step 7 – Install MySQL

If you want to use a database with your website, you need to install MySQL (or another database management system). To install MySQL, type:

sudo apt install mysql-server

After installation, you can log in to the MySQL terminal by typing:

sudo mysql
