I've got a few virtual hosts set up through nginx on my centos7 server. I'm getting certs by using letsencrypt certbot. By default certbot writes the vhost info to the /etc/nginx/nginx.conf file. This isn't the behavior I want. I use the /sites-available and /site-enabled folders with separate .conf files for each vhost. If I connect to a site in which the vhost and ssl info is listed in the nginx.conf it works fine. However if I copy the directives out and put them in a new conf file in the site-available folder (with a symlink in sites-enabled) it serves up the wrong certificate. It serves the one related to another vhost. I'd really like to keep my vhost configs in separate files rather than building them into the nginx.conf, but I can't seem to make that work.


UPDATE:

As requested here is the contents of my nginx -T call. None of the server blocks that are outside the conf are shown here though. They're loaded via the line that reads include /etc/nginx/sites-enabled/*.conf.

  • @MichaelHampton I've added the output, but it doesn't actually show the blocks that are loaded from external .conf files. The issue is I have 3 external .conf files as well. Each of these is set up for .ssl. However no matter which of those sites I go to it will only serve up the certificate for one of the hosts. If I take the blocks out of external files and put them in the global nginx.conf file it works fine though.

  • All of them should have shown up there in nginx -T if they were properly symlinked. Check your symlinks, and check ownership and permissions on the files and containing directories. Oct 29, 2020 at 16:16
  • @MichaelHampton the original files are all owned/grouped to root with 644 permissions. The symlink has the same ownership with a 777 permission.

    Nginx includes only the files ending in .conf, while the name of your "problematic" config file ends in .com. Nov 5, 2020 at 16:33

Your include line is include /etc/nginx/sites-enabled/*.conf; so you are including files ending in .conf. As I requested, your sites-enabled vhost configuration files are:

➜  sites-available cd ../sites-enabled
➜  sites-enabled ls -l
total 8
lrwxrwxrwx 1 root root 53 Oct 29 21:05 fullcontactmotherhood.conf -> /etc/nginx/sites-available/fullcontactmotherhood.conf
lrwxrwxrwx 1 root root 51 Oct 29 21:44 lonewolfdigital.com.conf -> /etc/nginx/sites-available/lonewolfdigital.com.conf
lrwxrwxrwx 1 root root 74 Oct 28 15:33 stairwell-soundboard-player.lonewolfdigital.com -> /etc/nginx/sites-available/stairwell-soundboard-player.lonewolfdigital.com
lrwxrwxrwx 1 root root 60 Oct 29 21:07 webhooks.lonewolfdigital.com.conf -> /etc/nginx/sites-available/webhooks.lonewolfdigital.com.conf`

Note that stairwell-soundboard-player.lonewolfdigital.com does not end in .conf but .com. Delete the link and make a new one which ends in .conf and reload your nginx:

ln -s /etc/nginx/sites-enabled/stairwell-soundboard-player.lonewolfdigital.com.conf /etc/nginx/sites-available/stairwell-soundboard-player.lonewolfdigital.com
systemctl reload nginx
