LVS+KEEPALIVED MASTER BACK 相互不通

我想配置一個LVS DR測試伺服器
主伺服器是 10.1.88.76
備伺服器是 10.1.88.77
虛擬IP是 10.1.88.81

問題是根據日誌，兩個伺服器都進入了MASTER狀態，可能是相互的通信問題。
1.相互可以PING通
2.兩台機器已經關閉了iptables

問題已經解決
I found the solution of this problem. The master virtual_router_id should equal to backup's.I found the solution of this problem. The master virtual_router_id should equal to backup's.

主備伺服器的virtual_router_id必須相同！
