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 keepalivedglobal_defs { notification_email { [email protected] [email protected] [email protected] } notification_email_from [email protected] 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 keepalivedglobal_defs { notification_email { [email protected] [email protected] [email protected] } notification_email_from [email protected] 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
