How To Secure Apache with Let's Encrypt on Ubuntu 16.04

If you are running a website on Apache web server, it is important to secure it with SSL/TLS encryption. Let's Encrypt is a free and open certificate authority that provides SSL/TLS certificates. In this tutorial, we will show you how to secure Apache with Let's Encrypt on Ubuntu 16.04.

Step 1: Install Apache

If you haven't already installed Apache on your Ubuntu 16.04 server, you can do so with the following command:

sudo apt-get update
sudo apt-get install apache2

Step 2: Install Let's Encrypt Client

Next, you need to install the Let's Encrypt client on your Ubuntu 16.04 server. You can do so with the following command:

sudo apt-get install letsencrypt

Step 3: Generate SSL/TLS Certificate

Once you have installed the Let's Encrypt client, you can generate an SSL/TLS certificate for your Apache web server with the following command:

sudo letsencrypt --apache -d yourdomain.com

Replace "yourdomain.com" with your actual domain name.

Step 4: Configure Apache to Use SSL/TLS Certificate

After generating the SSL/TLS certificate, you need to configure Apache to use it. You can do so by editing the Apache SSL configuration file with the following command:

sudo nano /etc/apache2/sites-available/default-ssl.conf

Replace "default-ssl.conf" with your actual SSL configuration file name.

Add the following lines to the SSL configuration file:

SSLCertificateFile /etc/letsencrypt/live/yourdomain.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/yourdomain.com/privkey.pem

Replace "yourdomain.com" with your actual domain name.

Save and close the file.

Step 5: Enable SSL/TLS and Restart Apache

Next, you need to enable SSL/TLS and restart Apache with the following commands:

sudo a2enmod ssl
sudo service apache2 restart

Step 6: Verify SSL/TLS Certificate

Finally, you can verify that your Apache web server is using SSL/TLS encryption by visiting your website in a web browser. The address should start with "https://" and show a green padlock icon.

Congratulations! You have successfully secured your Apache web server with Let's Encrypt on Ubuntu 16.04.
