Description Rob Crittenden 2014-08-08 13:46:21 UTC
Description of problem:

To enable SSL for rabbitmq the Cinder manifest needs support added. This has been done upstream at https://github.com/stackforge/puppet-cinder/commit/9d081c10368ca47cf8e6ec8c7e6ed7b77fe3baaa#diff-60ae41fd0a31977447947f59940ee9a4

Comment 1 Ivan Chavero 2014-08-11 23:45:31 UTC
i'll create a pull request for openstack puppet modules

Comment 2 Ivan Chavero 2014-09-11 20:40:30 UTC
The latest OPM RPM hast the required functionality openstack-puppet-modules-2014.1-21.8.el6ost

Comment 5 Prasanth Anbalagan 2014-09-26 15:13:15 UTC

Tried to reproduce the issue on latest RHEL 6.5/RHOS setup and observed error message with
rabbitmq. Could you please check the steps below. Let me know if you need more information or
need to access the setup for any triage purpose.

0) Installed RHOS allinone using packstack (openstack-puppet-modules-2014.1-21.8.el6ost did get installed).

1) Stopped openstack services using "openstack-service stop"

2) Created and added the certificates required for SSL communication as below,

    a) mkdir /etc/pki/rabbitmq
    b) cd /etc/pki/rabbitmq
    c) Generated .keyfile using "openssl genrsa -des3 -out 1024
    d) Generated certificate signing request using "openssl req -new -key -out"
    e) Generated a self signed certificate using "openssl x509 -req -days 365 -in -signkey -out"

3) Edited /etc/rabbitmq/rabbitmq.config as below,
     {rabbit, [
        {ssl_listeners, [5671]},
        {ssl_options, [{certfile,"/etc/pki/rabbitmq/"},
4) Enabled SSL Communication Between Rabbitmq and Cinder as below,

    openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_use_ssl True
    openstack-config --set /etc/cinder/cinder.conf DEFAULT kombu_ssl_certfile /etc/pki/rabbitmq/
    openstack-config --set /etc/cinder/cinder.conf DEFAULT kombu_ssl_keyfile /etc/pki/rabbitmq/
5) Restarted Openstack services using ""openstack-service start"

6) Tried to create volume types and volumes and observed the following error in /var/log/cinder/api.log and volume.log.

   Looks like the message broker is unreachable. Rabbitmq status below shows that it is running.   
   Any idea why this may be happening?

Comment 6 Rob Crittenden 2014-09-26 15:32:16 UTC
The root of the problem is you're still using port 5672. You need to use 5671.

IMHO you shouldn't set the kombu_* variables. AFAICT they are used for identity so you'd be presenting the server with its own cert.

I'd double-check file permissions as well on the cert and key.

I wonder if you'll ultimately have SSL trust issues with a self-signed cert.

Comment 7 Prasanth Anbalagan 2014-09-29 13:55:14 UTC

Thank you. 

1) I see that I have used 5671 in the ssl config. I changed it to 5672, instead of making the change on rabbitmq side. Is that ok?

  {rabbit, [
     {ssl_listeners, [5672]},
     {ssl_options, [{certfile,"/etc/pki/rabbitmq/"},

2) Removed kombu variables set before.

3) Here are the permissions for the certificate and key file,

-rw-r--r--. 1 root root 948 Sep 26 16:12 /etc/pki/rabbitmq/
-rw-r--r--. 1 root root 951 Sep 26 16:08 /etc/pki/rabbitmq/


I still see the following error. This time a different one about an unknown protocol.

Comment 8 Rob Crittenden 2014-09-29 16:15:45 UTC
I think you need to check the rabbit server logs to see if the server came up successfully with SSL enabled.

I'll attach a simple python script that can be used to test rabbit SSL directly to exclude any client (mis)configuration issues.

You just need to change the hostname and rabbit password in the file. You can get the password rabbit_password in from nova.conf.

Comment 9 Rob Crittenden 2014-09-29 16:16:45 UTC
Created attachment 942414 [details]
rabbit AMQP test script

Edit the script to set the FQDN (in your case IP address I guess) and the rabbit password, then run: python rabbit.py and you should get "Hello World!" back.

Comment 10 Prasanth Anbalagan 2014-09-29 17:04:51 UTC
Here is the result from the script. Also, the rabbitmq logs show that it is accepting connectiions, but then closes it out with an error report. Is there any way to get more verbose error message?

Comment 11 Rob Crittenden 2014-09-29 18:16:43 UTC
I don't know rabbitmq-server well so don't know a way to get more verbose debugging.

I don't think you can force the port to 5672 like this. I'm surprised the server started at all. The default RABBITMQ_NODE_PORT is 5672 and this listener is always configured, so you created a conflicting configuration. I'd stick with 5671 as it is the standard AMQP SSL port and it is what the OpenStack clients should be using when it comes to SSL.

I see the same error as you when I try to connect an SSL client to a non-SSL server.

My rabbitmq.config looks like:

  {rabbit, [

    {ssl_listeners, [5671]},
    {ssl_options, [{cacertfile,"/etc/ipa/ca.crt"},
    {default_user, <<"openstack">>},
    {default_pass, <<"9ca8271764fe05655579bac5738cdd89">>}

Comment 12 Prasanth Anbalagan 2014-09-29 21:57:24 UTC
After making the modifications above and generating certificates based on 
https://openstack.redhat.com/Securing_Services_Foreman, I was able to verify
rabbitmq communication with SSL enabled. Moving the bug to Verified.

SSL Listener comes up after enabling Rabbimq with SSL

=INFO REPORT==== 30-Sep-2014::00:45:42 ===
started SSL Listener on [::]:5671


Logs show that cinder operation is successful and is happening through SSL port 5671
