配置 keepalived非抢占模式方法

1、有两台keepalived主备服务器 192.168.122.38 是主 192.168.122.49是备

2、两台机器均已经使用了yum install keepalived进行了安装，安装完成后先把主配置文件备份一下

3、keep1的配置keepalived.conf，我们这里只做ip资源的漂移切换

! Configuration File for keepalived

global_defs {

   notification_email {

     acassen@firewall.loc

     failover@firewall.loc

     sysadmin@firewall.loc

   }

   notification_email_from Alexandre.Cassen@firewall.loc

   smtp_server 192.168.200.1

   smtp_connect_timeout 30

   router_id LVS_DEVEL

   vrrp_skip_check_adv_addr

   vrrp_strict

   vrrp_garp_interval 0

   vrrp_gna_interval 0

}

vrrp_instance VI_1 {

    state MASTER

    interface eth0

    virtual_router_id 50

    priority 100

    advert_int 1

    authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

        192.168.122.200

    }

}

4、keep2的配置keepalived.conf

! Configuration File for keepalived

global_defs {

   notification_email {

     acassen@firewall.loc

     failover@firewall.loc

     sysadmin@firewall.loc

   }

   notification_email_from Alexandre.Cassen@firewall.loc

   smtp_server 192.168.200.1

   smtp_connect_timeout 30

   router_id LVS_DEVEL

   vrrp_skip_check_adv_addr

   vrrp_strict

   vrrp_garp_interval 0

   vrrp_gna_interval 0

}

vrrp_instance VI_1 {

    state MASTER

    interface eth0

    virtual_router_id 50

    priority 99

    advert_int 1

    authentication {

        auth_type PASS

        auth_pass 1111

    }

    virtual_ipaddress {

        192.168.122.200

    }

}

5、当前vip 192.168.122.200在keep1上，目前把keep1重启操作。192.168.122.200飘向了keep2

6、但是当系统重启完成，恢复健康之后VIP 192.168.122.200 又被keep1给"争夺"回来了

7、keep1的keepalived.conf修改如下

state MASTER -->state BACKUP

增加nopreempt

8、当keep1重启完成，系统恢复之后，VIP这次没有再"抢夺"过来。配置成功，完美。

主要是在之前的master上操作，只有master“喜欢”抢占资源，而且还是默认抢占的哦
