Passwordless ssh issue
Hi Forum I've got an issue with a test installation of community edition ce-6.0.1-0.x86_64 RHEL5, on a CENTOS 6.4 set of VM's. I wanted to set up from scratch a cluster to improve knowledge... I created initially two VM's - with static IPs, 'host1' and 'host2'. SSH is set up on both. I've done the normal rpm -Uvh vertica-ce...rpm, and then run the install command: /opt/vertica/sbin/install_vertica -s host1,host2 -r vertica-ce-6.0.1-0.x86_64.RHEL5.rpm The installation crashes out with the message: Passwordless SSH access to other hosts (FAILED) Cannot connect from 192.168..... to host 192.168... without password.. Verify that /etc/ssh/sshd_config is configured properly on 192.168.... In sshd_config I've got: RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys2 I've checked on both VMs, and found that the .ssh and files contained at all mode 777. Thinking that there's a problem with my ssh config, I've not changed the config, but cleared out the contents of .ssh directory - used ssh-keygen, and ssh-copy-id [email protected] I've chmod'd the directory to 700 and files to 600, and I can do passwordless logins from one machine to the other... This makes me think that the sshd-config appears ok? Thinking that it's ok, I've re-run the /opt/vertica/sbin/install_vertica script again, and it's moved my current (working) ssh directory out of the way and re-created a new (non-working) .ssh directory and crashed out with the same error message... Can anyone think of what the issue may be, or whether the installer has an option for 'don't touch the ssh config'? :-) Many thanks in advance... :-) Carl.
