Apache 2.2 subdomains are showing same site as of main domain

i have main site on www.domain.com and have created one subdomain called demo.domain.com but when i try to access the subdomain demo.domain.com, its showing the same site as my main domain, how do i fix this? here are how i have defined the virtual hosts in my

/etc/httpd/conf/httpd.conf

<VirtualHost *:80>
     ServerAdmin webmaster@domain.com
     DocumentRoot /var/www/domain.com/public_html
     ServerName domain.com
     ServerAlias www.domain.com
</VirtualHost>

<VirtualHost *:80>
     ServerAdmin webmaster@domain.com
     DocumentRoot /var/www/demo.domain.com/public_html
     ServerName demo.domain.com
     ServerAlias www.demo.domain.com
</VirtualHost>

i even tried 

service httpd restart

it throws 

Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
[Mon Jan 13 15:54:14 2014] [warn] _default_ VirtualHost overlap on port 80, the first has precedence

i have added both the main domain and subdomain in the host file

[root@public_html]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
1.2.3.4 domain.com demo.domain.com

and i have created a A record for the subdomain name in my DNS manager pointing it to the my main vps IP - Address. my DNS file

demo    IN A    1.2.3.4
@           IN A    1.2.3.4
www         IN A    1.2.3.4

so when i access domain.com and demo.domain.com it shows the same page as of domain.com

i have created a index.html in

/var/www/demo.domain.com/public_html

[root@public_html]# cat index.html
<html>
  <head>
    <title>www.example.com</title>
  </head>
  <body>
    <h1>Success: You Have Set Up a Virtual Host</h1>
  </body>
</html>

so how i can fix this ? i am using centOS 6, 64 bit

when i try to access the subdomain demo.domain.com, its showing the same site as my main domain www.domain.com

Solution

  • As arco444 suggested.

    try

    cat /etc/httpd/conf/httpd.conf | grep NameVirtualHost

    and comment out 

    #NameVirtualHost *:80

    so itll become

    NameVirtualHost *:80

    then restart apache by entering

    service httpd restart

    now it should show sub-domains their respective sites/pages.
