How To Install Apache with Let’s Encrypt on Ubuntu 22.04 LTS

Install Apache with Let's Encrypt on Ubuntu 22.04

In this tutorial, we will show you how to install Apache with Let’s Encrypt on Ubuntu 22.04 on Ubuntu 22.04 LTS. For those of you who didn’t know, Let’s Encrypt is a nonprofit Certificate Authority providing certificates so that your websites can use secure connections. Certbot is an open-source software tool for integrating and managing Let’s Encrypt certificates on the web to enable a secure HTTPS protocol. It will automatically manage the Let’s Encrypt certificate for you.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Apache with Let’s Encrypt on Ubuntu 22.04 on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Apache with Let’s Encrypt on Ubuntu 22.04 LTS Jammy Jellyfish

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Apache HTTP Server on Ubuntu 22.04.

By default, the Apache is available on Ubuntu 22.04 base repository. Now run the following command below to install the latest version of Apache to your Ubuntu system:

sudo apt install apache2

After successfully installation, enable Apache (to start automatically upon system boot), start, and verify the status using the commands below:

sudo systemctl enable apache2
sudo systemctl start apache2
sudo systemctl status apache2

You can confirm the Apache2 version with the below command:

apache2 -v

Step 3. Configure Firewall.

Now we set up an Uncomplicated Firewall (UFW) with Apache to allow public access on default web ports for HTTP and HTTPS:

sudo ufw allow OpenSSH
sudo ufw allow 'Apache Full'
sudo ufw enable

Step 4. Accessing Apache Web Server.

Once successfully installed, open a web browser on your system and type the server’s IP in the address bar. You will get the default Apache server page:

Step 5. Create Apache Virtualhost.

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

sudo mkdir -p /var/www/html/domain.com/

Then, change the ownership and group of the directory:

sudo chown -R www-data:www-data /var/www/html/domain.com/

After that, we create an Apache virtual host to serve the HTTP version of the website:

sudo nano /etc/apache2/sites-available/www.domain.com.conf

Add the following file:

<VirtualHost *:80>

   ServerName domain.com
   ServerAlias www.domain.com
   ServerAdmin admin@domain.com
   DocumentRoot /var/www/html/www.domain.com

   ErrorLog ${APACHE_LOG_DIR}/www.domain.com_error.log
   CustomLog ${APACHE_LOG_DIR}/www.domain.com_access.log combined

   <Directory /var/www/html/www.domain.com>
      Options FollowSymlinks
      AllowOverride All
      Require all granted
   </Directory>

</VirtualHost>

Save and close the file, then restart the Apache webserver so that the changes take place:

sudo a2ensite www.domain.com.conf
sudo a2enmod ssl rewrite
sudo systemctl restart apache2

Step 6. Secure Apache with Let’s Encrypt on Ubuntu 22.04.

First of all, you need to install Certbot to get an SSL certificate with Let’s Encrypt:

sudo apt install certbot python3-certbot-apache

Next, get your SSL certificate with Let’s Encrypt by following these steps:

sudo certbot --apache

You will need to follow the interactive prompt and install the certificate. Since I have two domains, I will install SSL certificates for both domains:

Step 7. Auto-Renewal SSL.

Let’s Encrypt certificates have 90 days of validity, and it is highly advisable to renew the certificates before they expire. You can test automatic renewal for your certificates by running this command:

sudo certbot renew --dry-run
