Set up host file using port - apache

Question

I want to setup my host file to
127.0.0.2:5050 domain2.com => this is a local domain
when a type in my browser domain2.com, this return me : HTTP Error 404. The requested resource is not found.
i use this in apache
<VirtualHost 127.0.0.9:5050>
ServerAdmin info#domain2.com
DocumentRoot "C:/Users/My_Dir/LOOP/WebEnginer-2011/domain2_Dir/"
ServerName domain2.com
DirectoryIndex index.php index.html index.htm
ServerAlias www.domain2.com
ErrorLog "c:/wamp/xxxx/xxxx.log"
CustomLog "c:/wamp/xxxx/xxxx.log" common
</VirtualHost>
<VirtualHost 127.0.0.9:5050>
ServerAdmin info#domain2.com
DocumentRoot "C:/Users/My_Dir/LOOP/WebEnginer-2011/domain2_Dir/admin_Dir/"
ServerName admin.domain2.com
DirectoryIndex index.php index.html index.htm
ServerAlias www.admin.domain2.com
ErrorLog "c:/wamp/xxxx/xxxx.log"
CustomLog "c:/wamp/xxxx/xxxx.log" common
</VirtualHost>
but when i type 127.0.0.2:5050 i can see a web page. I want to use subdomain like admin.domain2.com
i can't use port 80 because IIS use that port.
How can i set up my host file to listen domain2.com?

Answer 1

That won't work since the hosts file only serves the purpose of mapping a hostname to an IP-address. The port number of a service is a different concept and is not handled by the "hosts" file nor the DNS-System. In Short: you can't supply a port number in the "hosts" file.
If your Webserver works on another port, you have to supply that information in the URL: http://domain2.com:5050.
The only other solution is to configure your Webservers to listen on a specific IP so that they don't interfere with each other. For example the IIS could listen on 127.0.0.1 and the Apache on 127.0.0.2 (the way you have already configured it).
There's a HOWTO for achieving that with the IIS. I'm not sure if that works for 127.0.0.x-IP's but I think it's worth a try.

Answer 2

It might be:
Your DNS resolver not resolving that properly
Some Apache webserver misconfiguration
Try this to get more information about that:
What if you ping domain2.com?
Also, try what happens if you put something like domain2.local in your hosts file. It might be some windows security c** disallowing you to overwrite the ip of an existing domain.
Why didn't you use 127.0.0.1? That should be fine, however
Make sure you have a properly configured VirtualHost that accepts requests to "domain2.com", or you just have a default virtualhost.
EDIT
What did you actually add to hosts file? The correct syntax would be:
127.0.0.2 domain2.com
