I've just done a long-overdue refresh on my VPS. One of the packages upgraded was Apache, to version 2.4-25. It appears the syntax of the site conf files has changed since the last version I was running and all is not totally "well on the farm."

I'm not an Apache wizard, but I found the following two URLs helped me with changing my configuration for 2.4:
https://httpd.apache.org/docs/trunk/upgrading.html
https://www.digitalocean.com/community/tutorials/migrating-your-apache-configuration-from-2-2-to-2-4-syntax

The main points I had to deal with were renaming my configuration files to end in ".conf", and replacing: "Order allow,deny
Allow from all" with "Require all granted" (or, for the opposite, "Require all denied").

I have two IP addresses bound to the server.

I am trying to achieve:

Running a number of different web sites on domains I own, each with its own folder on the filesystem.

This should be the same as for 2.2.

These websites are spread across HTTP a (80) and HTTPS (443) on both IP addresses.

I want Apache to recognise which site to serve from the URL, rather than the IP address.

My 'ports.conf' has the following entries:

Listen 80<IfModule mod_ssl.c> Listen 443 https</IfModule><IfModule mod_gnutls.c> Listen 443 https</IfModule>

I think I had to add the 'https' to each line that had '443' to make it work.

For each virtual host you will probably want the entry to start: <VirtualHost *:80> or <VirtualHost *:443> to match any IP address (you'll need a block for each to make it work for both, unless someone can suggest a clever way to do it all in one virtualhost entry).

As long as your VirtualHost has a statement giving the ServerName (and, for any alternate names, ServerAlias), this should work.

(As a side note, if you are using Certbot for your SSL certificates you will only want one VirtualHost entry per conf file or it will not recognise that site).

I want separate conf files for each site to make taking them up and down and reconfiguring easy.

This should be the same as for 2.2.

I want to be able to serve different sites from different folders on some subdomains e.g. example.com serves one site and mail.example.com serves another.

Again, I don't think the syntax for this has changed in 2.4, unless you were doing something clever (perhaps with macros?).

I hope that is of some help to you. You might need to provide a (suitably anonymised) copy of your virtualhost setup so that we can advise further.

Thanks
