The Basics of Web Server Configuration in Ubuntu

Before we dive into the more advanced configurations, let’s start with the basics of setting up a web server on Ubuntu. Here are the steps you’ll need to follow:

Step 1: Install Apache

The first step in setting up a web server on Ubuntu is to install Apache, the most popular web server software on the internet. To install Apache, open your terminal and run the following command:

Command
Description
sudo apt-get update
Updates the package list to ensure that you have the latest version of Apache available.
sudo apt-get install apache2
Installs Apache on your system.

Once Apache is installed, you can start the server by running the following command:

sudo systemctl start apache2

Step 2: Configure Your Firewall

Now that you’ve installed Apache, you’ll need to configure your firewall to allow traffic on the HTTP and HTTPS ports (80 and 443, respectively). To do this, run the following commands:

Command
Description
sudo ufw allow ‘Apache’
Allows traffic on Apache’s default ports (HTTP and HTTPS).
sudo ufw status
Displays the firewall status to confirm that Apache is now allowed through the firewall.

Step 3: Verify Your Server’s Configuration

To verify that your server’s Apache configuration is correct, you can open your web browser and navigate to your server’s IP address. If everything is working correctly, you should see the Apache default page.

Step 4: Create a Virtual Host

Now that you have Apache up and running, you can configure virtual hosts to host multiple websites on the same server. To create a virtual host in Ubuntu, follow these steps:

Step 4.1: Create a New Directory

First, create a directory to store your website’s files:

sudo mkdir /var/www/example.com

Step 4.2: Create a New Virtual Host File

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

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

Enter the following configuration:

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

Save the file and exit the editor.

Step 4.3: Enable the Virtual Host

Finally, enable the virtual host by running the following command:

sudo a2ensite example.com

Restart Apache for the changes to take effect:

sudo systemctl restart apache2

You should now be able to navigate to your website by entering its domain name in your web browser.

Step 5: Install and Configure SSL

If you want to secure your website with SSL/TLS encryption, you can use Let’s Encrypt to obtain a free SSL certificate. To install and configure SSL on your Ubuntu server, follow these steps:

Step 5.1: Install the Certbot Package

First, install the Certbot package by running the following command:

sudo apt-get install certbot python3-certbot-apache

Step 5.2: Obtain an SSL Certificate

Next, run the following command to obtain an SSL certificate from Let’s Encrypt:

sudo certbot --apache --agree-tos --redirect --email your-email@example.com -d example.com -d www.example.com

Replace your-email@example.com with your email address and example.com with your website’s domain name.

Step 5.3: Verify SSL Configuration

To verify that your SSL configuration is working correctly, navigate to your website using HTTPS in your web browser. If everything is working correctly, you should see a green padlock icon in your browser’s address bar.
