devstack multi-node tutorial fails

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

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

Re: devstack multi-node tutorial fails [In reply to]

Hi Viktor,

I've noticed similar issues (need to specify rabbit and glance api on
"compute nodes" even though it is unused) while running multi-node setups
with Quantum. I created a question on devstack's launchpad page for this,
but haven't heard anything yet:

some more comments to the current multi node tutorial of devstack??

Re: devstack multi-node tutorial fails [In reply to]

Hey Viktor, coud you send me the link ?
If it's within the official doc, we'll have a look, otherwise, I guess
you could contact the team directly :-)

Re: devstack multi-node tutorial fails [In reply to]

This is the Link:

http://devstack.org/guides/multinode-lab.html

The corrections would be:

it is at the moment necessary to install the "rabbit" service also on the
compute nodes (of course with the IP from the head node)

MYSQL_PASS -> MYSQL_PASSWORD

RABBIT_PASS -> RABBIT_PASSWORD

MULTI_HOST=1 -> MULTI_HOST=True (one I think only in the localrc config file
of the head node)

Some more comments concerning the ssh access (because of live migration)

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

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

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.

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

The devstack.org site is built from the gh-pages branch of devstack at
https://github.com/cloudbuilders/devstack/tree/gh-pages. Clone that, make
your changes and send a pull request. Let us know you've done that, it's
the only time that we use pull requests in that repo.

Re: devstack multi-node tutorial fails [In reply to]

I have been having issues with multi-node too.

I have just pushed this, to fix the issues with setting RABBIT_HOST:

Cheers,

This is the Link:

http://devstack.org/guides/multinode-lab.html

The corrections would be:
it is at the moment necessary to install the "rabbit" service also on the compute nodes (of course with the IP from the head node)

MYSQL_PASS -> MYSQL_PASSWORD
RABBIT_PASS -> RABBIT_PASSWORD
MULTI_HOST=1 -> MULTI_HOST=True (one I think only in the localrc config file of the head node)

Some more comments concerning the ssh access (because of live migration)

Cheers vic

Hey Viktor, coud you send me the link ?
If it's within the official doc, we'll have a look, otherwise, I guess you could contact the team directly :-)
