lvs的dr和tunl模式

DR模式是用的最多的
LVS机器上

#!/bin/bash
# websitedirector vip.
VIP=10.253.3.21
RIP1=10.253.3.14
RIP2=10.253.3.15
RIP3=10.253.3.16
case "$1" in
start)
/sbin/ipvsadm -C
#set lvs vip for dr
/sbin/ipvsadm --set 30 5 60
/sbin/ifconfig eth0:0 $VIP broadcast $VIP netmask 255.255.255.255 up
/sbin/route add -host $VIP dev eth0:0
/sbin/ipvsadm -A -t $VIP:80 -s wlc
/sbin/ipvsadm -a -t $VIP:80 -r $RIP1:80 -g -w 1
/sbin/ipvsadm -a -t $VIP:80 -r $RIP2:80 -g -w 1
/sbin/ipvsadm -a -t $VIP:80 -r $RIP3:80 -g -w 1
;;
stop)
/sbin/ipvsadm -C
/sbin/ipvsadm -Z
ifconfig eth0:0 down
route del $VIP >/dev/null 2>&1
echo "ipvsadm stoped"
;;
esac

RealServer上的配置

VIP=10.253.3.21
case "$1" in
start)
        ifconfig lo:0 $VIP netmask 255.255.255.255 broadcast $VIP
        /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 >/dev/null 2>&1
        echo "RealServer Start OK"
         ;;
stop)
        ifconfig lo:0 down
        route del $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

tunl模式的配置也类似
服务器上配置

#!/bin/bash
# websitedirector vip.
VIP=10.253.3.21
RIP1=10.253.3.14
RIP2=10.253.3.15
RIP3=10.253.3.16
#./etc/rc.d/init.d/functions
case "$1" in
start)
/sbin/ipvsadm -C
#set lvs vip for eth0:0
/sbin/ipvsadm --set 30 5 60
/sbin/ifconfig eth0:0 $VIP broadcast $VIP netmask 255.255.255.255 up
/sbin/route add -host $VIP dev eth0:0
/sbin/ipvsadm -A -t $VIP:80 -s wlc
/sbin/ipvsadm -a -t $VIP:80 -r $RIP1:80 -i  -w 1
/sbin/ipvsadm -a -t $VIP:80 -r $RIP2:80 -i  -w 1
/sbin/ipvsadm -a -t $VIP:80 -r $RIP3:80 -i  -w 1
;;
stop)
/sbin/ipvsadm -C
ifconfig eth0:0 down
route del $VIP >/dev/null 2>&1
echo "ipvsadm stoped"
;;
esac

RealServer
