Connecting to other servers

Hi,

I was wondering about how to connect let's say I got 4 different machines 3 are act as a server and the other one is a client on VirtualBox. Now server 1 is up and running to serve www.foo.com (or 192.168.0.13). So, a client can access to server 1, but accidentally server 1 got problem and turned down. My question is how to change/switch the server from server 1 to server 2/server 3 so www.foo.com still can up and running?

Thanks!

 

Thanks for your reply.

BTW what do you mean by "contents" is it all the website files? And how do I change the IP through Apache? Is it httpd.conf? Sorry, I'm quite new to Apache configuration.

Thanks

 

Great. I'll give a try.

Thanks for your helps.

 

Hi,

Sorry, where I can find DNS configuration? Because I'm still using virtual machine (VirtualBox). Not yet in real one.

Thanks
