编写检测服务down后所要执行的脚本

  #vi /usr/local/MySQL/bin/MySQL.sh  
  #!/bin/sh  
  pkill keepalived  
  #chmod +x /usr/local/MySQL/bin/MySQL.sh

注：此脚本是上面配置文件notify_down选项所用到的，keepalived使用notify_down选项来检查real_server的服务状态，当发现real_server服务故障时，便触发此脚本；我们可以看到，脚本就一个命令，通过pkill keepalived强制杀死keepalived进程，从而实现了MySQL故障自动转移。另外，我们不用担心两个MySQL会同时提供数据更新操作，因为每台MySQL上的keepalived的配置里面只有本机MySQL的IP+VIP，而不是两台MySQL的IP+VIP

启动keepalived

[root@leonfs keepalived]# /usr/local/keepalived/sbin/keepalived -D

[root@leonfs keepalived]# ps -ef|grep keep

root     30225     1  0 14:16 ?        00:00:00 /usr/local/keepalived/sbin/keepalived -D

root     30226 30225  0 14:16 ?        00:00:00 /usr/local/keepalived/sbin/keepalived -D

root     30227 30225  0 14:16 ?        00:00:00 /usr/local/keepalived/sbin/keepalived -D

在其他机器上ping vip：ping 192.168.0.222，可以ping通，关闭mysql服务，查看keepalived健康检查程序是否会触发编写的脚本（notify_down：MySQL.sh）：经确认触发（执行pkill keepalived）。

Keepalived故障转移测试：

※在windows客户端一直去ping  VIP（192.168.0.222），然后关闭192.168.0.53上的keepalived，正常情况下VIP就会切换到192.168.0.119上面去

※开启192.168.0.53上的keepalived，关闭192.168.0.119上的keepalived，看是否能自动切换，正常情况下VIP又会属于192.168.0.53

MySQL故障转移测试

※在192.168.0.53上关闭MySQL服务，看VIP是否会切换到192.168.0.119上

※开启192.168.0.119上的MySQL和keepalived，然后关闭192.168.0.119上的MySQL，看VIP是否会切换到192.168.0.53上

notify_master /etc/keepalived/scripts/start_haproxy.sh  #表示当切换到master状态时,要执行的脚本

notify_fault  /etc/keepalived/scripts/stop_keepalived.sh #故障时执行的脚本

notify_stop  /etc/keepalived/scripts/stop_haproxy.sh # keepalived停止运行前运行notify_stop指定的脚本 }

--添加服务

cp /usr/local/keepalived/etc/rc.d/init.d/keepalived  /etc/rc.d/init.d/

cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/

VRRPD配置包括3个类：

VRRP同步组（synchroization group）

VRRP实例（VRRP Instance）

VRRP脚本(VRRP Script)，

这里使用的是VRRP实例，VRRP脚本。

存在闹裂的可能性，即两个节点实际都处于正常工作状态，但是无法接收到彼此的组播通知，这时两个节点均强行绑定VIP，导致不可预料的后果。这时需要设置仲裁，即每个节点必须判断自身的状态（应用服务状态及自身网络状态），要实现这两点可使用自定义shell脚本实现，通过周期性的检查自身应用服务状态，并不断ping网关（或其他可靠的IP）均可。当自身服务异常或无法ping通网关，则认为自身出现故障，就应该移除掉VIP（停止keepalived即可），主要借助keepalived提供的vrrp_script及track_script实现。

可以在conf文件里编写脚本如

Vrrp_script chk_haproxy(script_name){ #定义一个检查脚本

script “filename” #shell脚本的路径，文件自定义规则可为：自身web服务故障（超时，http返回状态不是200）；无法ping通网关；产生以上问题即可停止keepalived

Interval 5 #运行间隔

}

然后在vrrp_instance VI_1{

Track_script{

Chk_haproxy

}

}

注：vrrp_script与vrrp_instance是一个级别的

如果是主-主模式，conf可以配置2个vrrp_instance，每个vrrp_instance对应1个vip，如下所示

vrrp_instance vip1 {

    state MASTER

    interface eth0

    virtual_router_id 51   #本机两个vrrp_instance组的此值不能相同，但对应备用节点的此值必须相同

    priority 99        #对应备用节点值应该比此值小

    advert_int 1

    authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

        192.168.100.1 /24

    }

}

vrrp_instance vip2 {

    state BACKUP

    interface eth0

    virtual_router_id 52  #本机两个vrrp_instance组的此值不能相同，但对应主节点的此值必须相同

    priority 90      #主节点的值应该比此值大

    advert_int 1

    authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

        192.168.100.2 /24

    }

}

另1节点配置相反。需要做好本地服务检测，以防止闹裂。
