VirtualHost configuration

问题

I need to configure two name-based virtual hosts in my Ubuntu PC. If I type the address http://mypage1 in browser, it should display my first customized html page and if I type the address http://mypage2, it should display my second customized html page. I tried out the following:

1. installed apache

2. created a file mypage1 inside sites-available with the contents as follows:

   <VirtualHost *:80>
    ServerName mypage1
    ServerAlias http://mypage1
    DocumentRoot /var/www/mypage1/html
   </VirtualHost>
   

3. created a similar file mypage2 inside sites-available

4. ran the commands a2ensite mypage1 and a2ensite mypage2 to generate soft links inside sites-enabled.
5. restarted apache using sudo /etc/init.d/apache2 restart

After doing the above steps, when I type mypage1 in firefox, I get dns_unresolved_hostname error.

Kindly help me how to resolve this problem.

回答1:

DNS unresolved means exactly what it said! It could not find the DNS entries for 'servers' called mypage1 or mypage2.

Add them to you /etc/hosts file like

127.0.0.1 mypage1 mypage2

If you are successful then you will probably get a different error, then you can start looking into virtual hosts configuration

回答2:

For one thing, you should set a NameVirtualHost for whatever IP(s) you intend to serve the files from. (If you don't, Apache will usually ignore the server name and just use whatever site is defined/included first.)

Also, make sure "mypage1" and "mypage2" are actual, valid domain names, or put them in /etc/hosts. Apache's knowing about them doesn't automatically make them known anywhere outside Apache -- especially to your machine's DNS resolver.
