在lvs服务器上运行的脚本lvs.sh,绑定VIP地址到LVS-MASTER上,并设定LVS工作模式等
#!/bin/bash SNS_VIP=192.168.1.108 SNS_RIP1=192.168.1.106 SNS_RIP2=192.168.1.107 ./etc/rc.d/init.d/functions logger $0 called with $1 case "$1" in start) # set squid vip /sbin/ipvsadm-set 30 5 60 #表示tcp空闲等待时间为30秒客户端关闭链接等待时间为5秒udp空闲等待为60秒 /sbin/ifconfig eth0:0 $SNS_VIP broadcast $SNS_VIP netmask 255.255.255.255 broadcast $SNS_VIP up /sbin/route add -host $SNS_VIP dev eth0:0 /sbin/ipvsadm -A -t $SNS_VIP:80 -s wlc -p 120 /sbin/ipvsadm -a -t $SNS_VIP:80 -r $SNS_RIP1:80 -g -w 1 /sbin/ipvsadm -a -t $SNS_VIP:80 -r $SNS_RIP2:80 -g -w 1 touch /var/lock/subsys/ipvsadm >/dev/null 2>&1 ;; stop) /sbin/ipvsadm -C /sbin/ipvsadm -Z ifconfig eth0:0 down route del $SNS_VIP rm -rf /var/lock/subsys/ipvsadm >/dev/null 2>&1 echo "ipvsadm stoped" ;; status) if [ !-e /var/lock/subsys/ipvsadm ];then echo "ipvsadm stoped" exit 1 else echo "ipvsadm OK" fi ;; *) echo "Usage: $0 {start|stop|status}" exit 1 esac exit 0
后端Web服务器上执行的realserver.sh,主要作用为:绑定VIP地址,并设定arp抑制
#!/bin/bash SNS_VIP=192.168.1.108 ./etc/rc.d/init.d/functions case "$1" in start) ifconfig lo:0 $SNS_VIP netmask 255.255.255.255 broadcast $SNS_VIP /sbin/route add -host $SNS_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/arpvannounce sysctl -p >/dev/null 2>&1 echo "RealServer Start OK" ;; stop) ifconfig lo:0 down route del $SNS_VIP >/dev/null 2>&1 echo "0" >/proc/sys/net/ipv4/conf/lo/arp_ignore echo "0" >/proc/sys/net/ipv4/conf/lo/arp_announce echo "0" >/proc/sys/net/ipv4/conf/all/arp_ignore echo "0" >/proc/sys/net/ipv4/conf/all/arp_announce echo "RealServer Stoped" ;; *) echo "Usage: $0 {start|stop}" exit 1 esac exit 0
