安裝Oracle 11.2.0.4 的RAC，在Grid 安裝時報錯：

[INS-41112]Specified network interface doesnt maintain connectivity across cluster nodes

 

首先嘗試在節點間ping 各個IP 位址沒有問題。

因為使用安裝程式做的SSH 驗證，所以嘗試測試ssh遠端連線是否還需要確認：

[[email protected] ~]$ ssh vdb1 date       # 驗證vdb1 sshThu Aug  7 15:20:44 CST 2014[[email protected] ~]$ ssh vdb2 date       # 驗證vdb2 sshThu Aug  7 15:20:49 CST 2014[[email protected] ~]$ ssh vdb1-priv date  # 驗證 vdb1-priv sshThe authenticity of host ‘vdb1-priv (172.168.1.18)‘ can‘t be established.RSA key fingerprint is 92:66:57:37:7b:fe:b0:05:5a:9b:ec:b5:3f:d1:07:8f.Are you sure you want to continue connecting (yes/no)? yes     Warning: Permanently added ‘vdb1-priv,172.168.1.18‘ (RSA) to the list of known hosts.Thu Aug  7 15:21:05 CST 2014[[email protected] ~]$ ssh vdb2-priv date  # 驗證 vdb2-priv sshThe authenticity of host ‘vdb2-priv (172.168.1.19)‘ can‘t be established.RSA key fingerprint is 92:66:57:37:7b:fe:b0:05:5a:9b:ec:b5:3f:d1:07:8f.Are you sure you want to continue connecting (yes/no)? yes   Warning: Permanently added ‘vdb2-priv,172.168.1.19‘ (RSA) to the list of known hosts.Thu Aug  7 15:21:18 CST 2014

發現使用vdb1-priv和vdb2-priv時需要確認，在2個節點間互相確認後，該步驟任然未通過驗證。

檢查發現是沒有關閉防火牆 ，關閉兩個節點的防火牆後，該問題解決。
