[Blog] Easy SSL for MistServer through Certbot (Linux-specific)
Hello everyone! This post we wanted to highlight a new feature in the latest MistServer builds (since version 2.17). This version not only added an integration with CertBot for Let’sEncrypt SSL certificates, but also added all SSL functionality to the Open Source edition of MistServer.
Before we start: if you're using MistServer together with a webserver (as in running MistServer on the same server that is hosting your website) we recommend using a reverse proxy. It just makes more sense to have a single SSL certificate, and this will also allow you to run MistServer on the same port as your website which looks more professional. So, this guide is only useful for setups that run MistServer “standalone”, without a webserver on the same machine. That said, let's dig into it!
With version 2.17 of MistServer we added a new tool in your MistServer install called “MistUtilCertbot”. This tool takes care of Certbot integration, meaning the entire setup can now be done with just a single command! (After both MistServer and Certbot are installed first, of course.)
Install Certbot Certbot is a *Nix only tool that's meant for easy SSL certificate management. It's a package in most distributions of Linux, so we recommend using your distribution’s package manager to install it. More information on Certbot can be found here, and distribution-specific instructions can be found here.
Run MistUtilCertbot through Certbot Once installed you can have Certbot set up your MistServer HTTPS certificate by running the following command (run this command as the same user you would usually run certbot as; it does not matter what user MistServer is running as):
certbot certonly --manual --preferred-challenges=http --manual-auth-hook MistUtilCertbot --deploy-hook MistUtilCertbot -d DOMAIN01,DOMAIN02,ETC
You'll have to change the
DOMAIN01,DOMAIN02,ETC part into your own domain(s), other than that there’s no need to make changes.
Set up auto-renewing of CertBot certificates This differs per distribution, so we recommend following the “Set up automatic renewal” step on certbot’s instructions page. There is no need to follow any of the other steps, as the rest is taken care of by our integration.
Done That's it! Your MistServer now has SSL enabled and it will be auto-renewing monthly!
