Hi,

I have 3 identical redhat machines with the same configuration. I have done all the previous steps before installation but when I insert the command:

/ opt / Vertica / sbin / install_vertica --hosts 10.1.24.201,10.1.24.202,10.1.24.203 --rpm vertica.rpm u dbadmin

I get the message:

Vertica Analytic Database 7.0.2-1 Installation Tool
Validating options ... >>
Mapping hostnames in --hosts (s) included to addresses ...
Starting >> installation tasks.
Getting system information for >> cluster (this May take a while) ...
Enter password for mymachine@10.1.24.202 (3 Attempts left):

I enter the password but I get the error:

Error: failed to get system information for all hosts
         (10.1.24.203) This operating system is not supported Could not be detected or
Hint: May be hidden additional failures.
Installation FAILED with errors.
Installation stopped before any changes Were Made.

Someone could tell me how can I fix this error?

Thanks,

    Hello Dani,

    Thanks for the response. From the Supported Platforms section of the 7.0.x documentation (http://my.vertica.com/docs/7.0.x/PDF/HP_Vertica_7.0.x_Supported_Platforms.pdf), the latest version of Red Hat we support is 6. However, Vertica 7.1.x currently does support Red Hat 6.5:

    Thanks,

    Hello Dani,

    So, after speaking with a colleague, it appears that we do in fact support Red Hat 6.5 running Vertica 7.0. The documentation is a bit vague, so I will try to have that cleared up. Sorry for the confusion on my end. At your earliest convenience, please send us the output of the installer log in the /opt/vertica/logs directory that coincides with the latest installation attempt.

    Sorry again for the confusion on my part.

    Thanks,
    Rory

    Finally I decided to create the cluster using de Management Console, but I have a problem when validating nodes. This error is:

    - Validation Group: Preparing for Validation
    Success: Test: Validating Ping: INFO: Ping succeeded
    Error: Test: Validating SSH connection: ERROR: Athentication failed for user root. Could be Because SELinux is enabled on the host OR a wrong private key is being used. If the problem still Persists, Please contact your administrator or HP / Vertica support.


    I have checked that SELinux is disabled and I have created the public and private keys. I have copied the public keys in all the nodes and the private key in the MC. But this error persist.

    Could you help me?

    Thank you,

    Can you run getenforce and see its output. Use setenforce to change it to Permissive.

    I have changed it to Permissive but the error persist.

    Any other ideas or anything that I could try?

    Thanks Siddarth,

    Check firewall settings as well. Stop IPtables and then try.  Did you changed to Permissive in every node?

    Siddarth, I changed to Permissive in one node because now I'm trying to validate this node. This is the same node where I have installed the MC.
    Moreover, I've already tried it with all ports open, and the firewall stopped.
    I've checked the manual and I think I've done all the steps...

    Coud be a problem with user or permissions?

    It may be a possibility. Can you now try to install from within the node instead of using MC?

    Ensure you can ssh as root without providing a password ( using RSA keys) across all hosts. Only when this works ( fix the RSA connection issues first) , then proceed with the install.

    I have verified I can ssh as dbadmin without providing a password.

    But when I try to "validate Hosts" in the Manage Console (MC) It show this error:

    Validate hosts failed. Reason: SqlMapClient operation; SQL[];--- The error occurred in create-cluster-step-sqlmap.xml.--- The error occurred while applying a parameter map.--- Check the createClusterStep.deleteByHostId-InlineParameterMap.--- Check the statement (update failed).--- Cause: java.sql.SQLTransactionRollbackException: Container was opened in read-only mode.; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException:--- The error occurred in create-cluster-step-sqlmap.xml.--- The error occurred while applying a parameter map.--- Check the createClusterStep.deleteByHostId-InlineParameterMap.--- Check the statement (update failed).--- Cause: java.sql.SQLTransactionRollbackException: Container was opened in read-only mode.

    In "Show Detail" it show another error:

    Success: Test: Validating Ping: INFO: Ping succeeded.
    Error: Test: Validating SSH connection: ERROR: athentication failed for user root. Could be because SELinux is enabled on the host OR a wrong private key is being used. If the problem still persists, please contact your administrator or HP/Vertica support.

    My question is: why this second error indicates "failed for user root"? The default user is dbadmin, and I have configure ssh by dbadmin.

    I hope you can help me.

    Thanks,
