Hi All,
I get the following error eventhough I have followed the instruction for Solaris R2. The instruction is enclosed. Please Advise! Thanks.
/app/cluvfy/runcluvfy.sh stage -post hwos -n nod1 -verbose
Result: User equivalence check failed for user "oracle".
ERROR:
User equivalence unavailable on all the nodes.
Verification cannot proceed.
Post-check for hardware and operating system setup was unsuccessful on all the nodes.
=========================
1. Log in as the oracle user.
2. If necessary, create the .sshdirectory in the oracle user’s home directory and
set the correct permissions on it:
$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
3. Enter the following commands to generate an RSA key for version 2 of the SSH
protocol:
$ /usr/bin/ssh-keygen -t rsa
At the prompts:
¦ Accept the default location for the key file.
¦ Enter and confirm a pass phrase that is different from the oracle user’s
password.
This command writes the public key to the ~/.ssh/id_rsa.pub file and the
private key to the ~/.ssh/id_rsafile. Never distribute the private key to anyone.
4. Enter the following commands to generate a DSA key for version 2 of the SSH
protocol:
$ /usr/bin/ssh-keygen -t dsa
At the prompts:
¦ Accept the default location for the key file
Pre-Installation Tasks 2-11
Creating Required Operating System Groups and User
¦ Enter and confirm a pass phrase that is different from the oracle user’s
password
This command writes the public key to the ~/.ssh/id_dsa.pub file and the
private key to the ~/.ssh/id_dsa file. Never distribute the private key to
anyone.
Add keys to an authorized key file: Complete the following steps:
1. On the local node, determine if you have an authorized key file
(~/.ssh/authorized_keys). If the authorized key file already exists, then
proceed to step 2. Otherwise, enter the following commands:
$ touch ~/.ssh/authorized_keys
$ cd ~/.ssh
$ ls
You should see the id_dsa.pub and id_rsa.pubkeys that you have created.
2. Using SSH, copy the contents of the ~/.ssh/id_rsa.puband
~/.ssh/id_dsa.pubfiles to the file ~/.ssh/authorized_keys, and provide
the Oracle user password as prompted. This process is illustrated in the following
syntax example with a two-node cluster, with nodes node1 and node2, where the
Oracle user path is /home/oracle:
[oracle@node1 .ssh]$ ssh node1 cat /home/oracle/.ssh/id_rsa.pub >>
authorized_keys
oracle@node1’s password:
[oracle@node1 .ssh]$ ssh node1 cat /home/oracle/.ssh/id_dsa.pub >>
authorized_keys
oracle@node1 .ssh$ ssh node2 cat /home/oracle/.ssh/id_rsa.pub >>
authorized_keys
oracle@node2’s password:
[oracle@node1 .ssh$ ssh node2 cat /home/oracle/.ssh/id_dsa.pub
authorized_keysoracle@node2’s password:
Note: Repeat this process for each node in the cluster
