About this project

Open

My website will have 4 servers. 3 servers are Server A,B and C (replication server that store data) -DONE already
Your job is..
To setup Server D or i call it as Monitor. It will use Heart beat node to receive the “life” for each servers. If one server down..
.

The ip will be passed to the neighbour server. To make sure the user can still use  the website without knowing the server is down. The monitor will assign an virtual ip to the neighbour servers.
So for example server A failed. Monitor will assign virtual ip A to B. If we check ipconf for server, it will have 2 ip now.
Virtual ip A and its own ip.

The monitor will always checking the "life". When server A is "up" again. It will pass back the ip to A.
