Cannot ignore down host 127.0.0.1 - it is not being removed

Hello,

 

I am trying to install vertica on AWS, while installing vertica I am getting the following error message on both 127.0.0.1 and with my ip.

 

what could be the issue?

 

./install_vertica --hosts ip-10-x.x.x.ec2.internal --dba-user dbadmin --dba-user-password [email protected]

  • Hi,

     

    Your install_vertica command is missing a few parameters.

     

    Please review and follow the AWS guide for installing Vertica on AWS : https://my.vertica.com/docs/Ecosystem/Amazon/UsingVerticaonAWSHTML/Default.htm

     

    Thanks

    Hi -

     

    Can you please let me know how was this resolved. I am facing the same thing while installing on AWS?

    Should I specify the--point-to-point option?

    You have to use the ip itself and not the host name given.

     

      Make sure you have edited your /etc/hosts file before installing the database, add you ip`s with thier specific node names.

     

     

    And when you run install Vertica cluster use the ipaddreses.

    Thanks! But i was already using IP address.Resolved the issue by adding the public key under /etc/ssh/authorized keys for root user. Also, to ignore down host / avoid the yes no promt for first sah loging, had to do a ssh-keyscan to add under /root/.ssh/known_hosts.

    All in all problem was with root trying to login into the server while vertica installation - Vertica automatically spawns psuedo terminal to ssh while installation
