Apache-2.2
心跳讓我心痛
我有 2 個 Ubuntu 11.04 VM,我在其上安裝了 Heartbeat + apache2 以實現“高可用性”設置。Heartbeat 已啟動並在兩者上執行,但我無法 ping 虛擬 IP(集群 ip)
從我遵循的指南中,心跳應該自動在活動節點上創建一個別名。但我在兩個虛擬機中都沒有看到任何別名
設置如下:

crm_mon -1
告訴我配置了 0 個資源。但我已經清楚地IPaddr
在 haresources 中添加了資源。我無法 ping 或瀏覽虛擬 IP。我在設置中做錯了嗎?
0 Resources configured
表示故障轉移 IP未配置為 HA 資源。順便說一句,如果您只需要 IP 故障轉移,那麼 CARP(通過 ucarp/ucarpd)要簡單得多。
