Keepalived
keepalived 未啟動並抱怨未設置虛擬 ID
我在 ubuntu 12.10 伺服器上安裝了 keepalived 包並對其進行了配置，但它稍後在 syslog 中抱怨必須設置虛擬 ID
保持活動配置

（這還不是答案，但是日誌文件在評論中太難讀了）
Ubuntu 12.10
再次，完全沒有問題

我按原樣使用 OP
keepalived.conf，並且能夠在沒有任何 syslog 錯誤的情況下啟動它，無論有無 eth0:1 (192.168.1.10)。安裝keepalived
apt-get install keepalived dpkg -l|grep keepalived ii keepalived 1:1.2.2-3ubuntu1 Failover and monitoring daemon for LVS clusters該軟體包沒有
keepalive.conf文件，只有一個空/etc/keepalived目錄。
