Same server, different Apache virtual hosts, second- and third-level domains

Hi there

I am afraid this must be in a FAQ. I have just joined Letsencrypt and very much beginner. This is what I need to do:

  • I deliver different web sites from the same server, Debian LAMP, using Apache virtual hosts. So typically I have all sorts of *.conf files in /etc/apache2/sites-available belonging to the different sites.
  • Some sites are third level domains. eg.
  • And I have a different set of sites in the format,, etc.

Right now everything runs fine with HTTP. I want to promote all of them to HTTPS. Does Lets encrypt allow that? If so, could you point me to the instructions?

Hi @ratnaji

that's the standard configuration most users have.

Read the basics

then select a client.

Hi Juergen
Thanks for providing the links! I am used to manually copy the certificates to the server and make them available to httpd. The concept of Let’s Encrypt surprised me.

Yep, it works though. I have already enabled SSL in two web sites, one with the second level domain and one with a third level doman.

The main concept of Letsencrypt is "Automation". Certificates are only 90 days valid, so you have to do that every 60 - 85 day.

Having a lot of domains that doesn't work.
