Problem with installing SciDB14.12 at Ubuntu12.04


#1

Hello,
I am a new user for SciDB … (I have sudo pemission at my laptop)
I am traying to install SciDB 14.12 at Ubuntu 12.04 to the first time , I am following the instructions at ‘SciDB-Installation-v14-12.pdf’ and have these problems:

1- Link is broken: the Cluster Install script : scidb.org/forum/viewtopic.php?f=16&t=364
2-I created the config.init from the link ‘https://github.com/Paradigm4/configurator’ ; but, what is this warning mean:
# WARNING: Make sure all of the below directories are created
# before you execute 'initall’
AND is there recommended number of servers

3- at Readme file, how can i make sure that iam done with these two requirments:

  • The coordinator node must have ssh connectivity to all the SciDB hosts (as listed in the configuration file).
  • This same user account must be on all SciDB hosts, each account@host with the same home directory (that is absolute pathname not same disk)

Thank you
Oraib

Cluster installer can be downloaded from this page:
viewtopic.php?f=14&t=1526

Look for deployment-14.12.tar link.

The warning about the directories means that all of the directories specified on the right side of options data-dir-prefix-X-Y must exist before the installation starts.

The requirements from the README files mean that you must have ssh connectivity from the default coordinator (first server listed in config.ini) to all of the other servers in the cluster. Cluster installer will be setting up password-less ssh access from the coordinator to all other servers. So, firewalls or anything that prevents unrestricted network access between the coordinator and the other servers has to be turned off prior to starting the installation.

The second statement in the README file states that the same user account with the exact same home directory must exist on all servers in the cluster. This is the account that will be used by scidb.
