lvs Dr模式（vip与dip、rip在不同网段配置）
一、网络配置
1、realserver1:
[root@Server1 ~]# ifconfig eth2 11.100.46.4/24
[root@Server1 ~]# route add default gw 11.100.46.254
[root@Server1 ~]# ifconfig eth1 192.168.2.3/24 up
脚本：
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[root@Server1 ~]# vim drauto.sh
#!/bin/bash
#
vip=192.168.3.1
interface=”lo:0″
case $1 in
start)
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 1 > /proc/sys/net/ipv4/conf/eth1/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
echo 2 > /proc/sys/net/ipv4/conf/eth1/arp_announce
ifconfig lo:0 ${vip}/32 broadcast $vip up
route add -host $vip dev $interface
;;
stop)
ifconfig $interface down
echo 0 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 0 > /proc/sys/net/ipv4/conf/eth1/arp_ignore
echo 0 > /proc/sys/net/ipv4/conf/all/arp_announce
echo 0 > /proc/sys/net/ipv4/conf/eth1/arp_announce
esac
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[root@Server1 ~]# ./drauto.sh start
2、realserver2:
[root@Server1 ~]# ifconfig eth2 11.100.46.9/24
[root@Server1 ~]# route add default gw 11.100.46.254
[root@server2 ~]# ifconfig eth1 192.168.2.4/24
脚本：
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[root@Server1 ~]# vim drauto.sh
#!/bin/bash
#
vip=192.168.3.1
interface=”lo:0″
case $1 in
start)
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 1 > /proc/sys/net/ipv4/conf/eth1/arp_ignore
echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
echo 2 > /proc/sys/net/ipv4/conf/eth1/arp_announce
ifconfig lo:0 ${vip}/32 broadcast $vip up
route add -host $vip dev $interface
;;
stop)
ifconfig $interface down
echo 0 > /proc/sys/net/ipv4/conf/all/arp_ignore
echo 0 > /proc/sys/net/ipv4/conf/eth1/arp_ignore
echo 0 > /proc/sys/net/ipv4/conf/all/arp_announce
echo 0 > /proc/sys/net/ipv4/conf/eth1/arp_announce
esac
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
[root@Server1 ~]# ./drauto.sh start
3、Director：
[root@Director ~]# ifconfig eth2 192.168.2.2/24
[root@ Director ~]# ifconfig eth2 11.100.46.11/24
[root@ Director ~]# route add default gw 11.100.46.254
[root@Director ~]# ifconfig lo:0 192.168.3.1/32 broadcast 192.168.3.1
[root@Director ~]# route add -host 192.168.3.1 dev lo:0
4、router
[root@Router ~]# ifconfig eth2 192.168.2.1/24
[root@ Router ~]# ifconfig eth2 11.100.46.254/24
[root@Router ~]# route add default gw 192.168.2.2
二、安装http
[root@Server1 ~]# yum -y install httpd
[root@server2 ~]# service httpd start
三、配置lvs调度
[root@Director ~]# ipvsadm -A -t 192.168.3.1:80 -s rr
[root@Director ~]# ipvsadm -a -t 192.168.3.1:80 -r 192.168.2.3 -g
[root@Director ~]# ipvsadm -a -t 192.168.3.1:80 -r 192.168.2.4 –g
四、测试配置
