Configuring SSH on All Cluster Nodes
Before you install and use Oracle Real Application clusters, you must configure secure
shell (SSH) for the oracle user on all cluster nodes. Oracle Universal Installer uses
the ssh and scp commands during installation to run remote commands on and copy
files to the other cluster nodes. You must configure SSH so that these commands do
not prompt for a password.
Configuring SSH on Cluster Member Nodes
To configure SSH, you must first create RSA and DSA keys on each cluster node, and
then copy the keys from all cluster node members into an authorized keys file on each
node. To do this task, complete the following steps:
Create RSA and DSA keys on each node: Complete the following steps on each
node:
1. Log in as the oracle user.
2. If necessary, create the .ssh directory in the oracle user’s home directory and
set the correct permissions on it:
$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
$ chmod 700
