Experiment of Linux LVS cluster Dr model

LVS-DR model implements HTTP Load Balancing cluster, VIP and Dip/rip are not on the same network.

No nonsense principle, a bunch of online piles. Directly on the topology and configuration scripts.

The network topology is as follows:

1.DR configuration script:

1#!/bin/Bash2 #3 # dr Configuration Script4 5vip='10.0.0.200'6Iface='eth1:0'7mask='255.255.255.255'8port=' the'9rs1='172.16.0.101'TenRs2='172.16.0.102' OneScheduler='WRR' AType='- G' -  -  Case$1 inch the start) -     ifconfig$iface $vip netmask $mask -Iptables-F -   +Ipvsadm-a-T ${vip}:${port}-s $scheduler -Ipvsadm-a-T ${vip}:${port}-R ${rs1} $type-W 1 +Ipvsadm-a-T ${vip}:${port}-R ${rs2} $type-W 1 A     Echo "The VS Server is ready!" at     ;; - stop) -Ipvsadm-C -     ifconfig$iface Down -     Echo "The VS Server is canceled!" -     ;; in*) -     Echo "Usage: $ (basename $) start|stop" toExit1 +     ;; - Esac

2.RS configuration script:
