2、在各web节点上创建realserver脚本
cat /root/sh/lvs_real.sh #!/bin/bash #Description: Config realserver script #Written by : opsren---- SNS_VIP=192.168.8.10 /etc/rc.d/init.d/functions case "$1" in start) /sbin/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/arp_announce sysctl -p >/dev/null 2>&1 echo "RealServer Start OK" ;; stop) /sbin/ifconfig lo:0 down /sbin/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 给予可执行权限： chmod +755 /roo/sh/lvs_real.sh 启动脚本： /root/sh/lvs_real.sh start三、MySQL高可用（双主）部署
1.MySQL安装与配置
这里采用mysql5.5.24二进制tar包
tar zxf mysql-5.5.24-linux2.6-x86_64.tar.gz -C /usr/local/mysql5.5
