Keepalived主主模型

　　1、确保确保iptables及selinux不会成为阻碍。保持集群时间同步
　　2、在ka1上
　　vim /etc/keepalived/keepalived.conf
global_defs {
   notification_email {
   root@localhost
   }
   notification_email_from keepalived@localhost
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id proxy1
   vrrp_mcast_group4 224.1.1.1
}
vrrp_instance VI_1 {
    state MASTER
    interface eth1
    virtual_router_id 66
    priority 100
    advert_int 1
    authentication {
      auth_type PASS
      auth_pass 123456
    }
    virtual_ipaddress {
      172.18.0.200/16
    }
}
vrrp_instance VI_2 {
    state BACKUP
    interface eth1
    virtual_router_id 88
    priority 80
    advert_int 1
    authentication {
      auth_type PASS
      auth_pass 654321
    }
    virtual_ipaddress {
      172.18.0.201/16
    }
}　　2、在proxy2上

　　vim /etc/keepalived/keepalived.conf

! Configuration File for keepalived
global_defs {
   notification_email {
   root@localhost
   }
   notification_email_from keepalived@localhost
   smtp_server 127.0.0.1
   smtp_connect_timeout 30
   router_id proxy2
   vrrp_mcast_group4 224.1.1.1
}
vrrp_instance VI_1 {
    state BACKUP
    interface eth1
    virtual_router_id 66
    priority 80
    advert_int 1
    authentication {
      auth_type PASS
      auth_pass 123456
    }
    virtual_ipaddress {
      172.18.0.200/16
    }
}
vrrp_instance VI_2 {
    state MASTER
    interface eth1
    virtual_router_id 88
    priority 100
    advert_int 1
    authentication {
      auth_type PASS
      auth_pass 654321
    }
    virtual_ipaddress {
      172.18.0.201/16
    }
}
