Let’s encrypt is a project that offers free ssl certificates for everybody. Yes, you don’t need to pay to have your own SSL certificate installed on your website. Today we will explore how to install Let’s Encrypt SSL on cPanel servers.
Important: at the time of writing this tutorial, setting up Let’s Encrypt for cPanel servers was pretty much a pain. Today cPanel already integrated Let’s Encrypt into their fantastic AutoSSL system.
Do not follow this tutorial, instead check out the following tutorial on how to enable AutoSSL on cPanel
Requirements to install Let’s Encrypt SSL on cPanel based servers:
- Dedicated or VPS server with root access.
- Python 2.7.x
Installing requirements for CentOS 6.x
CentOS 6.x comes with Python 2.6.x, that’s why we will need to upgrade to 2.7.x.
Let’s install epel & ius repos in order to install Python 2.7.x:
yum install epel-release
rpm -ivh https://rhel6.iuscommunity.org/ius-release.rpm
Finally, install Python 2.7. and Git:
yum --enablerepo=ius install git python27 python27-devel python27-pip python27-setuptools python27-virtualenv -y
Check if python 2.7.x was installed ok:
It should be located at /usr/bin/python2.7
Installing requirements for CentOS 7.x
yum -y install git
Install Let’s Encrypt SSL on cPanel using CentOS 6.x and 7.x
Get all the data from the letsencrypt Repo
cd /root git clone https://github.com/letsencrypt/letsencrypt cd letsencrypt
Run the letsencrypt installation:
The process may take a few minutes. If you see this message:
“No installers are available on your OS yet”
Then the installed finished and you are ready to install your first SSL certificate.
If you see this error:
Transaction Check Error: file /usr/bin/2to3 from install of python27-tools-2.7.11-1.ius.el6.x86_64 conflicts with file from package python-tools-2.6.6-64.el6.x86_64
The solution is to remove python-tools from your server:
yum remove python-tools
Run the let’s encrypt installer again and it should work.
Installing my first let’s encrypt SSL certificate
Issue the following command to install your ssl on yourwebsite.com
./letsencrypt-auto --text --agree-tos --email firstname.lastname@example.org certonly --renew-by-default --webroot --webroot-path /home/username/public_html/ -d yourwebsite.com -d www.yourwebsite.com
After that, the output should show something like this:
IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/yoursite.com/fullchain.pem. Your cert will expire on 2016-07-18. To obtain a new version of the certificate in the future, simply run Let's Encrypt again. - If you like Let's Encrypt, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le email@example.com [~/letsencrypt]#
