I’m trying to secure my CentOS 7 VPS with Let’s Encrypt. I’ve followed the guidelines in https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-centos-7 . I’ve set up virtual hosts, installed server dependencies and the Let’s Encrypt client. But when I try to set up the SSL certificate with:
./letsencrypt-auto --apache -d balnium.com -d mail.balnium.com
I get the error:
The apache plugin is not working; there may be problems with your existing configuration. The error was: NoInstallationError()
The Apache Plugin for Let’s Encrypt is not working, but how do I make it work?
Could you check letsencrypt.log for more information? I.e., more details about what could be the problem with Apache.
Osiris, thank you for answering. The contents of that file are:

@Osiris Hi, does that help?
Not really I’m afraid…
Do you get any extra debug info when you run the letsencrypt-auto command with the extra options -vvv?
@Osiris This is what I get:

And in the letsencrypt.log file now I have:

Thank you
Is this a regular CentOS server with the distro-provided httpd package (i.e. what you get with yum install httpd), or are you using some sort of control panel (something like cPanel) or a custom version of apache? Any additional context you could add regarding your server might help.
Yes, I’m using Cpanel / WHM, and have Magento 1.9 installed. The server has a web server and DNS server. What else can I tell you?
If you have Cpanel/WHM I’d suggest using the latest version which has support for Let’s Encrypt built in, and you can automatically obtain and maintain certificates uptodate easily that way.
