First we need to configure static IP in ubuntu system.
# vim /etc/network/interfaces
Main IP system IP
auto eth0
iface eth0 inet static
address 192.168.1.92
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 8.8.8.8 8.8.4.4
Virtual IP
auto eth0:1
iface eth0:1 inet static
address 192.168.1.93
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
:wq
#sudo /etc/init.d/networking restart
# ifconfig (you can see both IPs)
#ping from other system it will work.
Folder redirection
# vim /etc/apache2/httpd.conf
<Virtualhost 192.168.1.92:80>
Servername 192.168.1.92
Serveralias ami.org
Documentroot /var/www
</virtualhost>
<VirtualHost 192.168.1.93:80>
DocumentRoot /var/www/wordpress
ServerName 192.168.1.93/
Serveralias ami.in
</VirtualHost>
# sudo /etc/init.d/apache2 restart
Go to web browser and see .It will work
