dir:

ipvsadm -C

清空之前ipvsadm

iptables -t nat -F

防火墙规则清空v

rs1,rs2:

vi /etc/sysconfig/network-scripts/ifcfg-eth0

更改rs1,rs2网卡网关信息为正常网关

dir:

ifdown eth1 （ifdown eth0:1）

关闭不用到的ip

DR模式需要多个公网IP ，将客户请求直接发出给客户端

3. LVS/DR 配置

三台机器:

director(eth010.222.138.200, vip eth0:1: 10.222.138.10)

real server1(eth0 rip: 10.222. 138.201, vip lo:0: 10.222.138.10)

real server2(eth0 rip: 10.222.138.202, vip lo:0: 10.222.138.10)

Director 上 vim /usr/local/sbin/lvs_dr.sh //增加

#! /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

然后director上执行: bash /usr/local/sbin/lvs_dr.sh

两台rs上执行: bash /usr/local/sbin/lvs_dr_rs.sh

dir 上

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

IP Virtual Server version 1.2.1 (size=4096)

Prot LocalAddress:Port Scheduler Flags

-> RemoteAddress:Port Forward Weight ActiveConn InActConn

TCP 10.222.138.10:80 wrr

-> 10.222.138.201:80 Route 3 0 0

-> 10.222.138.202:80 Route 1 0 0

打开另外一台centos ,curl 10.222.138.10来测试
