Configuring SSH or RCP on All Cluster Nodes<br />
You must configure SSH separately <strong>for</strong> each <strong>Oracle</strong> software installation owner that<br />
you intend to use <strong>for</strong> installation.<br />
To configure SSH, complete the following:<br />
2.10.3.1 Create .SSH, and Create RSA Keys On Each Node<br />
Complete the following steps on each node:<br />
1. Log in as the software owner (in this example, the crs user).<br />
2. To ensure that you are logged in as the <strong>Oracle</strong> user, and that the user ID matches<br />
the expected user ID you have assigned to the <strong>Oracle</strong> user, enter the commands id<br />
and id crs. Ensure that <strong>Oracle</strong> user group and user and the terminal window<br />
process group and user IDs are identical. For example:<br />
2-22 <strong>Oracle</strong> <strong>Clusterware</strong> <strong>Installation</strong> <strong>Guide</strong><br />
$ id<br />
uid=502(crs) gid=501(oinstall) groups=501(oinstall),502(crs)<br />
$ id crs<br />
uid=502(crs) gid=501(oinstall) groups=501(oinstall),502(crs)<br />
3. If necessary, create the .ssh directory in the crs user's home directory, and set<br />
permissions on it to ensure that only the oracle user has read and write<br />
permissions:<br />
$ mkdir ~/.ssh<br />
$ chmod 700 ~/.ssh<br />
4. Enter the following command:<br />
$ /usr/bin/ssh-keygen -t rsa<br />
At the prompts:<br />
■ Accept the default location <strong>for</strong> the key file (press Enter).<br />
■ Enter and confirm a pass phrase unique <strong>for</strong> this installation user.<br />
This command writes the RSA public key to the ~/.ssh/id_rsa.pub file and<br />
the private key to the ~/.ssh/id_rsa file.<br />
Never distribute the private key to anyone not authorized to per<strong>for</strong>m <strong>Oracle</strong><br />
software installations.<br />
5. Repeat steps 1 through 4 on each node that you intend to make a member of the<br />
cluster, using the RSA key.<br />
2.10.3.2 Add All Keys to a Common authorized_keys File<br />
Complete the following steps:<br />
1. On the local node, change directories to the .ssh directory in the <strong>Oracle</strong><br />
<strong>Clusterware</strong> owner’s home directory (typically, either crs or oracle).<br />
Then, add the RSA key to the authorized_keys file using the following<br />
commands:<br />
$ cat id_rsa.pub >> authorized_keys<br />
$ ls<br />
In the .ssh directory, you should see the id_rsa.pub keys that you have<br />
created, and the file authorized_keys.<br />
2. On the local node, use SCP (Secure Copy) or SFTP (Secure FTP) to copy the<br />
authorized_keys file to the oracle user .ssh directory on a remote node. The
