Open Stack

Hmmmm, who would be the responsible person to make corrections and insert
some more comments to the current multi node tutorial of devstack??

 

Cheers Viktor

Hey,
no you don't need to, the only case where the SSH exchange is mandatory is
for the [live|classi] migration

Another thing:

 

Is it really necessary to implement password-less ssh login via
.ssh/authorized_keys?

 

For me it works without it.

Thanks for the feedback
as for the multi_node mode, no it supposes you spawn a nova-network
component on every compute node

Hi,

 

I just want so say, that some days ago the stack.sh script hast been changed
concerning the rabbit server installation.

The current description for multi node tutorial
(http://devstack.org/guides/multinode-lab.html) will fail.

 

At the moment it is necessary to install the rabbit service on the compute
hosts TOO (but of course with the IP from the master node)!!

e.g.:

 

ENABLED_SERVICES=n-cpu,n-net,g-api,rabbit

RABBIT_HOST=$MASTERNODE

RABBIT_PASSWORD=pass

 

 

Otherwise the compute node tries to find a rabbit-mq server on localhost!

 

There are also some other wrong details in the multi-node toturial.

 

It must be:

 

RABBIT_PASSWORD and MYSQL_PASSWORD instead of MYSQL_PASS und RABBIT_PASS

 

Und the parameter MULTI_HOST=1 has to be change to MULTI_HOST=True (and
should only be available on the master node, as I understand it right).

 

 

Cheers Viktor
