If you [...]]]> I noticed that the rabbitmq-stomp had stopped working on my servers after a reboot. The servers were using the Ubuntu debian package of rabbitmq and had been updgraded to RabbitMQ 1.5.3 and stomp had not since I was manually installing rabbitmq-stomp from the mercurial repositories (cause I could not find any ubuntu packages for rabbitmq-stomp).

If you used something similar to the install process described in my earlier Deploying RabbitMQ and Stomp on Ubuntu you can do the following:

Update RabbitMQ server

For Ubuntu

sudo apt-get update
sudo apt-get upgrade rabbitmq-server

For Macintosh Leopard

Need to update the rabbitmq-codegen and rabbitmq-server using mercurial:

cd /usr/lib/erlang/lib/rabbitmq-codegen
hg pull
hg update rabbitmq_v1_5_3

cd /usr/lib/erlang/lib/rabbitmq-server
hg pull
hg update rabbitmq_v1_5_3

For both Ubuntu and Leopard

Update RabbitMQ-Stomp

cd /usr/lib/erlang/lib/rabbitmq-stomp
hg pull
hg update rabbitmq_v1_5_3

You can see what release tags are available after th hg pull via the command:

hg tags

Make sure there isn’t already an /etc/rabbitmq/rabbitmq.conf . If there is merge /etc/default/rabbitmq into /etc/rabbitmq/rabbitmq.conf (/opt/local/etc/ instead of /etc if you are using MacPorts)

Otherwise just move it:

mv /etc/default/rabbitmq /etc/rabbitmq/rabbitmq.conf

Rebuild the rabbitmq-stomp programs

Still in /usr/lib/erlang/lib/rabbitmq-stomp

For Ubuntu

make RABBIT_SERVER_SOURCE_ROOT=../rabbitmq_server-1.5.3 all

/etc/init.d/rabbitmq-server restart

For Macintosh Leopard

make all

If you updated rabbitmq-server make sure it builds and run

cd /usr/lib/erlang/lib/rabbitmq-server
make -j run

If it starts ok you can quit and then from now on run it by issuing the command:

/opt/local/lib/erlang/lib/rabbitmq-server/scripts/rabbitmq-server -detached

Synaptic repository addition

Ubuntu Documentation for Managing Repositories via the Command Line

How to use the RabbitMQ Debian repository and available RabbitMQ Debian packages

The repositories are described in /etc/apt/sources.list

So [...]]]> Install rabbitmq via synaptic

Make sure that the erlang package is installed

Add a repository from the rabbitmq site

Set up Repository via the Synaptic GUI tool

(http://www.rabbitmq.com/debian/)

Synaptic repository addition

Set up Repository via command line

Ubuntu Documentation for Managing Repositories via the Command Line

How to use the RabbitMQ Debian repository and available RabbitMQ Debian packages

The repositories are described in /etc/apt/sources.list

So do the following:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

Edit /etc/apt/sources.list and add the following line:

deb http://www.rabbitmq.com/debian/ testing main

Then update the apt-get environment:

wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc
sudo apt-get update

Install the RabbitMQ Server

Set up Repository via the Synaptic GUI tool

Synaptic Erlang Packages

Set up Repository via command line

sudo apt-get install rabbitmq-server

This should have installed the main portion of the code base in /usr/lib/erlang/lib/rabbitmq_server-1.5.1 (The trailing version number may be different than 1.5.1)

After it installed the server, make sure its stopped

# /etc/init.d/rabbitmq-server stop

Install rabbitmq-stomp

I could not find any ubuntu/debian packages so I installed it from the Mercurial repository. If you don’t already have Mercurial (the hg command) then you can install it with the following command:

apt-get install mercurial

Install the rabbitmq-stomp code

This also will go parallel to where the ubuntu package put the stomp server main code and the rabbit-codegen.

cd /usr/lib/erlang/lib/
hg clone http://hg.rabbitmq.com/rabbitmq-stomp/

Compile the stomp code

Build and test run rabbitmq and stomp via make

cd /usr/lib/erlang/lib/rabbitmq-stomp
make RABBIT_SERVER_SOURCE_ROOT=../rabbitmq_server-1.5.1 all

This should produce an output like:

mkdir -p ebin
erlc -I ../rabbitmq_server-1.5.0/include -I include -o ebin -Wall +debug_info  src/rabbit_stomp.erl
erlc -I ../rabbitmq_server-1.5.0/include -I include -o ebin -Wall +debug_info  src/stomp_frame.erl 

Add a file /etc/default/rabbitmq and Restart rabbitmq_server

You need to tell the main rabbitmq_server to load and run the rabbitmq-stomp stuff when it starts up. You do that by creating this file with the following content:

SERVER_START_ARGS='
  -pa /usr//lib/erlang/lib/rabbitmq-stomp/ebin
  -rabbit
     stomp_listeners [{"0.0.0.0",61613}]
     extra_startup_steps [{"STOMP-listeners",rabbit_stomp,kickstart,[]}]'

Restart the Rabbitmq_server:

/etc/init.d/rabbitmq_server start

You can do a

ps -ax | grep stomp

and see an erlang process that is running the rabbit-stomp process.

Install ruby stomp client code and test

Install the ruby stomp gems

If you don’t have ruby already installed:

sudo apt-get install ruby
sudo apt-get install rubygems

Then install the ruby stomp gem

sudo gem install stomp

Run the ruby receiver client in one window

ruby /usr/lib/erlang/lib/rabbit-stomp/examples/ruby/cb-receiver.rb

In another window run the ruby sender client

ruby /usr/lib/erlang/lib/rabbit-stomp/examples/ruby/cb-sender.rb

In the receiver window you should see 10,000 test message lines:

...
Test Message number 9998
Test Message number 9999
All Done!

That’s it! Now you can use Stomp
