LVS的DR设置测试

#! /bin/bash
echo 1 > /proc/sys/net/ipv4/ip_forward
ipv=/sbin/ipvsadm
vip=10.222.138.10
rs1=10.222.138.201
rs2=10.222.138.202
ifconfig eth0:1 $vip broadcast $vip netmask 255.255.255.255 up
route add -host $vip dev eth0:1
$ipv -C
$ipv -A -t $vip:80 -s wrr
$ipv -a -t $vip:80 -r $rs1:80 -g -w 3
$ipv -a -t $vip:80 -r $rs2:80 -g -w 1

两台rs上：vim /usr/local/sbin/lvs_dr_rs.sh

#! /bin/bash
vip=10.222.138.10
ifconfig lo:0 $vip broadcast $vip netmask 255.255.255.255 up
route add -host $vip lo:0
echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore
echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce
echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore
echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce

dir 上 

[root@dir network-scripts]# ipvsadm -ln
