Web :: General :: Need help with IP aliasing and Apache Virtual Hosting
By: thepreacher Great Britain  Date: 30/06/2009 18:17:19  English French  Points: 20 Status: Answered
Quality : Excellent
I really need your help with this. Its been two weeks now and still stuck. All i need to do is this:

I have a 2wire router, 5 static IP addresses and 10 domains to host. On the router i have configured the public gateway ip and also assigned a static ip to my ubuntu 8.04 server. The server is also configured with the same static ip. It works because the default apache page displays over the internet. I am also able to now connect via sftp and putty romotely.

My problem starts when i add ip aliases to current NIC - eth0. The reason for the ip alising is that on the one NIC we want to host 3 domains which must all have SSL and apart from adding more NICards IP alising is the other alternative which does not cost us money.

The issue is that I have tried to configure the sites on apache2 as best as I know and at the moment none of the sites can be view from the net. If i disable everything leaving just the one site, it works. I have attached detailes of my current settings hoping that someone can help.

Details of the Interfaces file:

root@pmctserver1:/etc/apache2/sites-enabled# nano /etc/network/interfaces

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 217.20.29.17
netmask 255.255.255.248
broadcast 217.37.29.23
gateway 217.37.29.22

auto eth0:0
iface eth0:0 inet static
name Ethernet alias LAN card
address 217.20.29.18
netmask 255.255.255.0
broadcast 217.37.29.23

auto eth0:1
iface eth0:1 inet static

Details of the Vhost configuration for a domain all the other domains are copies of this with the right changes made to the servername, documentroot etc..:

Sorry I made a mistake in the last section of the post. The following is the correct code

root@pmctserver1:/etc/apache2# ifconfig

yo

First quick & dirty idea : I wouldn't do this : (for each domain)


VirtualHost *:80



but rather :


VirtualHost 217.20.29.17:80



(for instance)
