<VirtualHost> Configuration segment
<VirtualHost 192.168.149.1>
ServerAdmin root@abc.com
DocumentRoot/www/abc
ServerName www.abc.com
</VirtualHost>
<VirtualHost 192.168.149.2>
ServerAdmin root@good.com
DocumentRoot/www/good
ServerName www.good.com
</VirtualHost>
Step 3: create a home page file for different virtual sites

LVS is a Linux kernel-Based Server Load balancer system that combines keepalived, heartbeat + Ldirectord, Red Hat piranha, and other highly available suites. It is specialized in load balancing, high availability, and scalability, it is often used for high-concurrency WEB Services.
