1 真實服務器real server 配置
1.1.1 Lvs_rs的配置。
在/etc/rc.d/init.d/中新建一個腳本。
注：我會提供已經寫好的腳本，只需複製就行了，腳本名字叫lvs_rs,複製到/etc/rc.d/init.d下（如下）
lvs_rs腳本代碼
#!/bin/sh
# chkconfig: 2345 72 08
# description: Config realserver lo:0 port and apply arp patch
VIP=192.168.48.88 (這個是服務器虛擬ip地址)
. /etc/rc.d/init.d/functions
case $1 in
start)
echo "lo:0 port starting"
echo "0" >/proc/sys/net/ipv4/ip_forward
/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
/sbin/route add -host $VIP dev 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
sysctl -p
;;
stop)
echo "lo:0 port closing"
ifconfig lo:0 down
echo "1" > /proc/sys/net/ipv4/ip_forward
echo "0" > /proc/sys/net/ipv4/conf/all/arp_announce
;;
*)
echo "Usage: $0 {start|stop}"
exit 1
esac
chmod +x /etc/rc.d/init.d/lvs_rs
chkconfig --add lvs_rs
將lvs_dr和lvs_switch複製到/etc/ha.d/resource.d/
注：lvs_dr和lvs_switch的腳本我會提供。（如下）
1.1.2 啓動服務
主節點 備用節點都起動服務 service heartbeat start
/etc/ha.d/resource.d/ldirectord start
2 測試
查看主lvs的ip信息，現在vip在主lvs上面。
