IP Address Planning:

cip:192.168.55.2

DIP:

eth1:172.16.1.254

eth0:192.168.55.5

vip:eth0:0 192.168.55.30

rip1:172.16.1.10

rip2:172.16.1.11

1 . First install the httpd on the backend real server and configure the index.html page. Two back-end servers can be accessed on the director.

2 . Configure VIP on Director

3, configure Ip_forward on director, is to turn on the IP forwarding function

Several issues to be aware of:

First: When configuring LVS, all hosts do not consider the rules of the firewall, so I am the direct service iptables stop.

Second: IPVSADM configuration Command This experiment is to use RR scheduling algorithm, more other algorithms can be studied by themselves.

Third: In the configuration of real server I was added port, if the backend is 8080, the port can be. This enables port forwarding.
