modifying SSH ports when installing Oracle RAC causes CRS to fail to install

Source: Internet
Author: User

For security reasons, the SSH port of the server is modified from the default of 22 in order to 22222

When installing RAC, Oracle users trust each other, but they cannot connect directly via SSH, and must add-P 22222 to

This results in a failure to validate the CRS when it is installed, showing:

Caught Cluster exceptionprkc-1044:failed to check Remote command execution setup for node TGDB1 using SHELLS/USR/BIN/SS H 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]]


It appears that Oracle is a direct-call SSH command, and does not add-P 22222, which leads to the illusion of communication between nodes


Workaround:

Modify/etc/service

Put one of these ssh 22222/tcp # ssh Remote Login Protocol

The port modified to 22222 resolved
