1、Keepalived配置和测试过程forlinux安装环境：两台server：Systemx3650M3Node1：硬盘：130GCPU：2颗E5620@2.40GHz内存：4GNode2：硬盘：130GCPU：2颗E5620@2.40GHz内存：8G1、安装redhat6.4系统用U盘安装rhel-server-6.4-x86_64-dvd.iso分区：/boot200M/boot/efi200MSwap4096M/13000M只安装Basic版本，不要安装桌面需要在language里面选择chinese包安装系统完成后设置网卡eth0No

2、de1：Node2：2、设置keepalivedNode1：15!ConfigurationFileforkeepalivedglobal_defs{router_id234567#router_id，配置一个网络唯一的ID}vrrp_instanceVI_3{#为keeplived实例号，一般一台服务器只有1个实例，不用更改stateBACKUP#为keepalived初始状态，此处需要设置成BACKUPnopreempt#配置为非抢占模式，在node1切到node2，vip从node1飘到node2后，node1恢复后，服务不会再切回no

3、de1，而是继续让node2做MASTER，服务在node2上面继续跑interfaceeth0#为启用keepalived的接口，根据实际情况设置virtual_router_id40#为keepalived虚拟ID，同一集群必须相同priority100#服务优先级，MASTER设置为100，BACKUP设置为90advert_int1#心跳区间设置为1秒authentication{auth_typePASSauth_pass10101010#设置验证密码，同一集群必须相同}virtual_ipaddress{172.16.0.120d

4、eveth0labeleth0:0#设置服务IP，devlabel可省略}notify_master"/etc/keepalived/notify.shmaster"#切换成master，执行一次脚本notify_backup"/etc/keepalived/notify.shbackup"#切换成backup，执行一次脚本notify_fault"/etc/keepalived/notify.shfault"#切换成fault，执行一次脚本}Node2：15!ConfigurationFileforkeepalivedglobal_defs

8、设置关闭两个系统的防火墙设置keepalived服务开机启动：chkconfigkeepalivedon2、进行keepalived服务切换试验初始状态：Node1
