Install and Configure Linux Virtual Server (LVS) for Load Balancing

The operational team in charge of the web servers has created two new Apache HTTP servers in preparation for a marketing campaign. You have been tasked with setting up a Linux Virtual Server to serve as a single access point and load balancer for potential clients. The Apache servers are already configured and running on real-server1 and real-server2 on port 80 on both hosts. You must install and configure LVS on the lvs-server. The virtual service that you create should use 110.0.1.501, listen on port 80, and use round robin as its scheduling algorithm. Once the virtual service is created, add real-server1 and real-server2 as real servers to the virtual service using NAT as the IP load balancing method.

Important notes:

• /etc/sysconfig/ipvsadm must be manually created for RHEL/CentOS (this is required for the service to start).
• Once you have completed all the tasks, you can test the virtual service by running curl http://10.0.1.50. This will return the index.html and should alternate between real-server1 and real-server2.
