nstalling Certbot

Follow the instructions on the official website to install it. The steps are roughly as follows: [3]

First, update your snapd version to the latest version.

 snap install core; sudo snap refresh core

Next, install Certbot.

snap install --classic certbot

Finally, add the symbolic link.

ln -s /snap/bin/certbot /usr/bin/certbot

Now that the installation of Certbot is complete, we will issue and install a certificate.

Issuing and Installing a Certificate

To issue and install the certificate, simply run the following command: [4]

certbot certonly --apache

When you run it, you will be prompted to enter the following information, so enter it appropriately.

• Your email address

• Whether to receive notification emails

• The domain name for which you want to issue the certificate ( sv1.example.com e.g.

If you want to support multiple domain names, sv1.example.com, www.example.com, example.com just enter them separated by commas.

The certificate will be installed in /etc/letsencrypt/live/sv1.example.com/fullchain.pem and the corresponding private key in. /etc/letsencrypt/live/sv1.example.com/privkey.pem

Change settings for HTTPS

Let's set up HTTPS. First, disable the default site configuration file.

a2dissite 000-default.conf

Next, create a site configuration file.

cd /etc/apache2/sites-available/

 vim mysite.conf

 vim mysite-ssl.conf

Here is an example with mysite.confa site configuration file :mysite-ssl.conf

# vi /etc/apache2/sites-available/mysite.conf

Finally, enable the module and site configuration files and restart the service.

a2enmod ssl

a2ensite mysite.conf

a2ensite mysite-ssl.conf

systemctl restart apache2.service

Checking HTTPS operation

Try accessing the site again as shown below 

https://sv1.example.com
