I have instance with multiple interfaces and I am trying to configure Apache with IP-based virtual hosting to serve multiple websites, but for some reason it just returns the main document root.

I followed this tutorial to get multiple interfaces working.

What is wrong: The website should show /var/www/mydomain/index.html, but instead it shows /var/www/html/index.html.

What I have tried: Using *:80 in VirtualHost, which works but the goal is to have multiple VirtualHosts each from different IP/interface. Removing port from VirtualHost: Doesn't do anything. Changing Listen 80 to Listen 92.168.1.231:80, which fails with Cannot assign requested address: AH00072: make_sock: could not bind to address 92.168.1.231:80. This is worrying and I haven't found any explanation what is happening. There is nothing else listening the port and if I just listen all 80 ports it works fine.

Info on my config:

sudo netstat -pntl (when having Listen 80 in httpd.conf and Apache running)

httpd.conf is pretty much vanilla except changing admin email, removing auto-indices from main document root and setting server name.

  • I wonder if the reason it won't bind to the specific IP is because it is already bound to 0.0.0.0 which includes the more specific one too. Could you check that? What is your netstat -pntl output? Commented Dec 16, 2016 at 21:27
  • You were trying to (listen and) create a vhost on 92.168.1.231 but your machine does not have that address; it has (among others) 192.168.1.231. 92 and 192 are different. Commented Dec 21, 2016 at 11:57
  • @dave_thompson_085 Welp... That would explain it.... No idea how I didn't notice that xD Commented Dec 21, 2016 at 13:05

In the main server config you should have:

Listen 80

This instructs apache to listen on all interfaces (and thus on all IPs). Only change it, if you do not want apache to listen on all interfaces/IPs.

Your VHosts should be configured as follows:

<VirtualHost 192.168.1.231:80> ServerName mydomain1.com DocumentRoot /var/www/mydomain1 ... </VirtualHost> <VirtualHost 192.168.1.232:80> ServerName mydomain2.com DocumentRoot /var/www/mydomain2 ... </VirtualHost>

Also check that your local dns server or /etc/hosts file is pointing to the correct IP address.

I didn't have /etc/hosts configured right, but fixing that didn't help. I switched from IP based virtual hosts to domain based and it got fixed magically. Don't really know why but it works.
