How to Host Multiple domain under a single IP

How to Host Multiple domain under a single IP, iam using cent os, webmin?

 

If u have apache installed. U need to set up virtual hosting for your server.
editing /etc/httpd/conf/httpd.conf

and u add domains like this:

<VirtualHost *:80>
DocumentRoot /home/domain1.com/htdocs
ServerName domain1.com
ServerAlias *.domain1.com
</VirtualHost>

<VirtualHost *:80>
DocumentRoot /home/domain2.com/htdocs
ServerName domain2.com
ServerAlias *.domain2.com
</VirtualHost>

 

Thank you for your replay..
i have some doubts, If i have a domain say www.domain.com which is using one public ip 10.20.10.10,and The DNS is pointed in www.name.com(Domain registrar)
Now i want to host another website say www.domain2.com,In the DNS(domain registrars DNS).I should use the same DNS configuration for the second and third domain ( 10.20.10.10)? OR I shold maintain my own DNS server to find the other website?
and i have some requirement
if i type 10.20.10.10 it should display the www.domain.com instead of blank page
can you tell me the steps to do that?
Thank You

 

you can host your dns with your domain registrar and put the same ip (ip of your server) in A record for both domains
and why you need anything to show by ip instead of domain name?

 

thank you i want to access my website by typing both ip and name.will it work ?

 

i think there is either a "default server" entry or you put * in ServerName to access by ip.
but i strongly advise AGAINST it. Do you want google to index your site by ip?

 

your web server identfies which virtual domain you want to acces, depending
on the http header
if you type the ip address which domain would you like to access

 

if you want multiple sites on single ip it will be port based

in other case, it will be hostname (domain.com) based....

but its definitely possible

 

you have to define virtual host and the same can be done via cpanel using add-on domains, check host name details here hostname
