Hi,

I installed Vertica and now I want to create a cluster with 3 nodes.
The command I type to create the cluster is:

/opt/Vertica/sbin/install_vertica --hosts 10.1.24.203,10.1.24.204,10.1.24.205 --rpm vertica.rpm --dba-user dbadmin

The message that appears is that the hosts 203 and 204 were Successful, but there is a problem with the host 205, the message that appears is this:

/opt/vertica/oss/python/bin/python: No module named vertica


Can you help me?

Thanks,

    Make sure root and dbadmin ids can passwordless ssh to that node

    Hi Wayne Wong,

    Both root and dbadmin are unable to passwordless ssh.
    The configuration is the same for all 3 nodes.

    Any other ideas?

    Thanks,

    On node 205 you could check for the rpm -

    rpm -qa | grep vertica

    ... and if it is there, then check for the following -

    ls -l /opt/vertica/oss/python/lib/python2.7/site-packages

    .
    .
    .

    lrwxrwxrwx 1 root root     31 2011-10-26 10:19 vertica -> /opt/vertica/share/eggs/vertica

    I am running into a similar problem, when I run ls -l /opt/vertica/oss/python/lib/python2.7/site-packages  -

    lrwxrwxrwx 1 root root     31 2011-10-26 10:19 vertica -> /opt/vertica/share/eggs/vertica does not exist.

    Also,  root and dbadmin are able to passwordless SSH.

    If you can, try installing the rpm on the problem node and running the install from there.

    I'll give that a try.  I also ran ln -s /opt/vertica/share/eggs/vertica /opt/vertica/oss/python/lib/python2.7/site-packages and now I run into this:

    I have solved this problem, following the next steps:

     

    At different nodes that doesn't work, you should go to 

     

    /opt/vertica/oss/python/lib/python2.7/site-packages/

     

    and create this links, if they doesn't exist:

     

    ln -s /opt/vertica/share/eggs/vertica   /opt/vertica/oss/python/lib/python2.7/site-packages/vertica

     

    ln -s /opt/vertica/share/eggs/py /opt/vertica/oss/python/lib/python2.7/site-packages/py

     

    ln -s /opt/vertica/share/eggs/ipaddress.pyc   /opt/vertica/oss/python/lib/python2.7/site-packages/ipaddress.pyc

     

    ln -s /opt/vertica/share/eggs/ipaddress.py   /opt/vertica/oss/python/lib/python2.7/site-packages/ipaddress.py

     

    ln -s /opt/vertica/share/eggs/flufl   /opt/vertica/oss/python/lib/python2.7/site-packages/flufl

     

    For me, this solution have solved my problem, and I could finish the installation without problems.

     

    I hope this can help you.

     

    Centos7 + vertica 7.2.0.1

     

    Regards.
