安裝ORACLE RAC時修改ssh端口導致CRS無法安裝

爲了安全起見,服務器的ssh端口從默認的22修改爲了22222

在安裝RAC時,oracle用戶間做了互信,但是並不能通過ssh直接連接,必須要加上-p 22222才能

這就會導致在安裝crs時驗證不通過,表現爲:

Caught Cluster ExceptionPRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh 

tgdb1: Connection refused

  [PRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh 

tgdb1: Connection refused]

  [PRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh 

tgdb1: Connection refused

  [PRKC-1044 : Failed to check remote command execution setup for node tgdb1 using shells /usr/bin/ssh and /usr/bin/rsh 

tgdb1: Connection refused]]

看來oracle是直接調用的ssh命令,並不會加上-p 22222,這就導致了節點間不能通信的假象

解決辦法:

修改/etc/service

把其中ssh   22222/tcp         # SSH Remote Login Protocol

的端口修改爲22222解決
