                   CustomLog logs/dummy-host.example.com-access_log common

               </VirtualHost>

:wq

 

2) # mkdir /opt/ website_directory1 && cd /opt/ website_directory1

 

3) # vim index.html

IP Based Virtual Hosting 

1. One IP and One website

2. To enable “Named Based Virtual Hosting” comment the “NameVirtualHost” tag in configuration file.

 

Practical 

<SERVER>

1) IP ALISING

·       

                              # ifconfig eth0:0 192.168.0.103 netmask 255.255.255.0

·       

                              Copy the “ifcfg-eth0” file and make necessary changes in it.

 

2) Comment the “NameVirtualHost” directive.

 

3) Go to “Listen” Directive and comment that line also adds following line:

               Listen <NIC_1-IP>:80 i.e. Listen 192.168.0.102:80

               Listen <NIC_2-IP>:80 i.e. Listen 192.168.0.103:8000 [Here I am changing port]

 

4) In VH (Virtual Host), Instead of  “*” give NIC_1 & NIC_2 IP address in respective VH.

# vim /etc/httpd/conf/httpd.conf

               <VirtualHost 192.168.0.102:80>

                   ServerAdmin webmaster@dummy-host.example.com

                   DocumentRoot /opt/website_directory1

                   ServerName first.com

                   DirectoryIndex index.html

                   ErrorLog logs/dummy-host.example.com-error_log

                   CustomLog logs/dummy-host.example.com-access_log common

               </VirtualHost>

               <VirtualHost 192.168.0.103:8000> [Here also I am changing port]

                   ServerAdmin webmaster@dummy-host.example.com

                   DocumentRoot /opt/ website_directory2

                   ServerName second.com

                   DirectoryIndex index.html

                   ErrorLog logs/dummy-host.example.com-error_log

                   CustomLog logs/dummy-host.example.com-access_log common

               # vim /etc/hosts

                              <NIC_1-ip>      first.com

                              <NIC_2-ip>      second.com

 

2) Check website via Browser or “elinks” command.

               # elinks http://first.com

               # elinks http://second.com:8000      [How to call website from client with port]
