In this tutorial we will teach you how to install Let’s Encrypt with Apache on Ubuntu 16.04.

Let’s Encrypt is an open SSL Certificate Authority (CA) which offers free domain validated (DV) certificates for your websites. SSL Certificates are used to ensure a secure encrypted connection between a web server and a user’s web browser. SSL Certificates need to be issued by Let’s Encrypt and they are valid for 90 days. Note that they are the most trusted by many web browsers today.

Requirements:

To begin with the installation process, you are required to have Apache or Nginx installed on your server. If you have no web server installed on your virtual server, use the guide below to install Apache. You will also require a registered domain name with its record pointing to your server’s IP address. For the purpose of this guide we are going to use ‘yourdomain.com’

Step 1: Install CertBot

Execute the commands below.

sudo apt-get install software-properties-common python-software-properties

sudo add-apt-repository ppa:certbot/certbot

sudo apt-get update

sudo apt-get install python-certbot-apache

Step 2: Install Let’s Encrypt SSL

Install Let’s Encrypt SSL certificate on your domain making sure to replace ‘yourdomain.com’ with your own domain.

sudo certbot --apache -d yourdomain.com

Step 3: Redirecting the HTTP traffic to HTTPS

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access. ——————————————————————————- 1: No redirect – Make no further changes to the webserver configuration. 2: Redirect – Make all requests redirect to secure HTTPS access. Choose this for new sites, or if you’re confident your site works on HTTPS. You can undo this change by editing your web server’s configuration. ——————————————————————————- Select the appropriate number [1-2] then [enter] (press ‘c’ to cancel): 2 Redirecting vhost in /etc/apache2/sites-enabled/000-default.conf to ssl vhost in /etc/apache2/sites-available/000-default-le-ssl.conf   ——————————————————————————- Congratulations! You have successfully enabled https://yourdomain.com

Step 4: Reneweing the SSL certificate with a cron job

Create a cron job so the SSL certificate is renewed automatically. Execute the following commands.
crontab -e

After, append the following line.

0 0 1 * * /usr/bin/letsencrypt renew >> /var/log/letsencrypt-renew.log

Save and close the file, then restart the cron service so the changes take effect.

service cron restart Open ‘https://yourdomain.com’ using the web browser of choice and verify if Let’s Encrypt SSL is installed correctly. This is all, the Let’s Encrypt SSL certificate should now be installed successfully on your website.
