lvs+keepalived，執(zhí)行ipvsadm查不到real server 地址

hanool

各位大俠
     在虛擬環(huán)境初次使用lvs+keepalived。配置之后發(fā)現(xiàn)，工作不正常。

     VIP：192.168.75.253
     LVS1(master) 192.168.75.135
     LVS2(backup) 192.168.75.136
     RealServer      192.168.75.142 （目前只使用一個Real，應(yīng)該可以吧？)

配置
主：
cat /etc/keepalived/keepalived.conf
global_defs {
   router_id LVS_DEVEL_MASTER
}

vrrp_sync_group VGM {
      group {
            VI_1
      }
}

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    lvs_sync_daemon_inteface eth0
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.75.253
    }
}

virtual_server 192.168.75.253 80 {
    delay_loop 6
    lb_algo rr
    lb_kind DR
    nat_mask 255.255.255.0
    persistence_timeout 50
    protocol TCP

    real_server 192.168.75.142 80 {
        weight 100
        TCP_CHECK {
            connect_timeout 3
            nb_get_retry 3
            delay_before_retry 3
            connect_port 80
        }
    }
}

備：
cat /etc/keepalived/keepalived.conf
global_defs {
   router_id LVS_DEVEL_BACKUP
}

vrrp_sync_group VGM {
      group {
            VI_1
      }
}

vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    lvs_sync_daemon_inteface eth0
    virtual_router_id 51
    priority 80
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    virtual_ipaddress {
        192.168.75.253
    }
}

virtual_server 192.168.75.253 80 {
    delay_loop 6
    lb_algo rr
    lb_kind DR
    nat_mask 255.255.255.0
    persistence_timeout 50
    protocol TCP

    real_server 192.168.75.142 80 {
        weight 1
        TCP_CHECK {
            connect_timeout 3
            nb_get_retry 3
            delay_before_retry 3
            connect_port 80
        }
    }

}

查看keepalived安裝是正常：
ps -ef | grep keep
root     20917     1  0 13:52 ?        00:00:00 keepalived -D
root     20918 20917  0 13:52 ?        00:00:00 keepalived -D
root     20919 20917  0 13:52 ?        00:00:00 keepalived -D
root     21396  2123  0 14:49 pts/0    00:00:00 grep keep

但是，執(zhí)行
ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddressort Scheduler Flags
  -> RemoteAddressort           Forward Weight ActiveConn InActConn
TCP  192.168.75.253:http rr persistent 50


后面什么都沒有了，按理說應(yīng)該有REal ip的呀。
請問是什么原因，謝謝！

你的real上啟動腳本了嗎？
