Virtual Hosting in Apache

by
Virtual Hosting is a term used to refer the practice of running multiple websites on a single machine.Virtual hosts can be IP-based, meaning that you have a different IP address for every web site, or name-based, meaning that you have multiple names running on each IP address. The fact that they are running on the same physical server is not apparent to the end user.

The following commands are tested on RedHat and CentOS.

Add the following lines in your configuration file
# vi /etc/httpd/conf/httpd.conf
<VirtualHost *:80>
ServerAdmin root@server.example.com
ServerAlias server2.example.com
DocumentRoot /home
ServerName storage.estuate
ErrorLog logs/deepak.example.com.log
CustomLog logs/deepak.example.com.access_log
</VirtualHost>
Here "*" signifies your apache server will listen to any IP you have used for web server configuration on your machine. You should make an habbit of using proper IP or name instead of "*".

ServerAdmin ==> sets the contact address that the server includes in any error messages it returns to the client.If the httpd doesn't recognize the supplied argument as an URL, it assumes, that it's an email-address and prepends it with mailto: in hyperlink targets. However, it's recommended to actually use an email address.

ServerAlias ==> This directive sets the alternate names for a host.

ServerName ==> This directive sets the request scheme, hostname and port that the server uses to identify itself. This is used when creating redirection URLs.

DocumentRoot ==> This directive specifies the root directory of the files you want to be visible on your web server

Adding some more features to your virtual hosts
# vi /etc/httpd/conf/httpd.conf
<VirtualHost *:80>
ServerAdmin root@server.example.com
ServerAlias server2.example.com
DocumentRoot /home
ServerName storage.estuate
<Directory /home/deepak/mypage.html>
AllowOverride None
Order Deny,Allow
Deny from All
</Directory>
</VirtualHost>
AllowOverride None will disable the access to .htaccess file

By default users are allowed to access all the directories inside the document root on the web server. To override this rule we use the following directive
<Directory /home/deepak/mypage.html>
Order Deny,Allow
Allow from all
</Directory>
