cannot add node to cluster

[Theron Conrey]

I've configured the cluster, and in trying to add a node via the command line:

sudo euca_conf -addnode <fqdn of this server>

it prompts me for a password for the eucalyptus user. This is not documented on how to proceed.

user error for the passwd above. I've followed the steps given from the above command. When running the command on the cc server, it succeeds. When trying to add a seperate node to the node it errors out.

end of echo back to screen:

hit return to continue

//var/lib/eucalyptus/keys/*: No such file or directory
ERROR: could not syncronize keys, check authorized_keys on <host>, then run this command again.

I've verified that the keys are working, su - eucalyptus and ssh to cc and back without passwds.

I can confirm it happens to me too. I've also tried it on Debian Lenny with the same effect.

If you are mixing distros, you will have to manually sync keys by scp'ing $EUCALYPTUS/var/lib/eucalyptus/keys/* from the cluster controller to $EUCALYPTUS/var/lib/eucalyptus/keys/ to the nodes.

hope that helps

Yes, minutes after posting a comment I figured out that the problem was on the node: Eucalyptus was installed in /opt. Theron, is it the same in your case? If it is, I suggest closing as invalid.

how did you fix the problem? I am installing the eucalyptus 1.5.2. have trouble to addnode because it keep shows permission denied. here is the detail what I did

http://open.eucalyptus.com/wiki/Eucalyp ... nty_v1.5.2

cloud-control and cluster-control are in one machine with ubuntu-server
node-controller in another machine with ubuntu-desktop
obviously it is 1.5.2 version

Have trouble to add node to the cloud. see below

    The configuration will not have this node.
    Hint: to setup passwordless login to the nodes as user eucalyptus, you can
    run the following commands on node 128.192.62.212:

    Be sure that authorized_keys is not group/world readable or writable

I run the instruction on the node computer,and then run "sudo euca_conf -addnode 128.192.62.212" again, still get the same error. any suggestions will be greatly appreciated.

richilee,

after you modified the NC, have you tried to login using ssh from the CC? Could you do so wihout having to enter a password? Yours seem more an ssh problem than a eucalyptus one. I'll mark this bug as invalid for now, feel free to reopen if you thin the problem is indeed in eucalyptus.
