Figured I’d write this one up quickly as it proved to annoy the hell out of me at 4:30am this morning getting it working on a live server.

Apache 2 can serve SSL content to multiple vhosts on your setup, provided they use different IP addresses, this post will give you a quick run down on how to do it.

First up we need to actually add the new IP to the machine in /etc/network/interfaces.

auto eth0
iface eth0 inet static
    address 10.1.1.7
    netmask 255.255.255.0
    gateway 10.1.1.1

auto eth0:1
iface eth0:1 inet static
    address 10.1.1.8
    netmask 255.255.255.0

Replace my IPs with your own.

Restart networking.

sudo /etc/init.d/networking restart

Next task is Apache 2 to configure it to listen on both IPs.

/etc/apache2/ports.conf

My changes

<IfModule mod_ssl.c>
    Listen 10.1.1.7:443
    Listen 10.1.1.8:443
    NameVirtualHost 10.1.1.7:443
    NameVirtualHost 10.1.1.8:443
</IfModule>

That basically tells Apache to listen to port 443 on both those IP addresses and sets up 2 NameVirtualHosts, 1 for each IP:PORT.

The next step is to set up the VirtualHosts, I am going to use a sample that has almost no directives, excluding all of the actual SSL directives to make things easier to read.

Host 1

<VirtualHost 10.1.1.7:443>
    ServerName web1.example.com
    DocumentRoot /path/to/html1
</VirtualHost>

Host 2

<VirtualHost 10.1.1.8:443>
    ServerName web2.example.com
    DocumentRoot /path/to/html2
</VirtualHost>

That is a very basic config but I hope it helps you understand how each VirtualHost actually works when multiple IPs are used.

sudo apache2ctl configtest
sudo /etc/init.d/apache2 restart
