LVS+Heartbeat
LVS1和LVS2所完成一样的工作，那么配置脚本也相同。唯一不同的是heartbeat配置文件ha.cf心跳地址不同。
真实的web，mysql，ftp……配置一样
LVS配置
#!/bin/bash
######lvs######
ifconfig eth0:0 222.90.88.88 broadcast 222.90.88.88 netmask 255.255.255.255 up
route add -host 222.90.88.88 dev eth0:0
-C
ipvsadm -A -t 222.90.88.88:80 -s rr
ipvsadm -a -t 222.90.90.88.88:80 -r 222.90.88.10 -g
ipvsadm -a -t 222.90.90.88.88:80 -r 222.90.88.20 -g
ipvsadm
Web配置
#!/bin/bash
######real server######
ifconfig lo:0 222.90.88.88 broadcast 222.90.88.88 netmask 255.255.255.255 up
route add -host 222.90.88.88 dev lo:0
######ipvsadm######
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
sysctl -p

四台LINUX主机（LVS1,LVS2和SEV1,SEV2）
