Simple way to install RabbitMQ in Ubuntu?

The simplest way is to remove any trace of Erlang or RabbitMQ on your system, then go to http://www.erlang-solutions.com/section/132/download-erlang-otp for an Ubuntu Erlang binary (the VM that runs RabbitMQ) and then go here http://www.rabbitmq.com/download.html to get RabbitMQ.

For Erlang, choose 64 bit or the unspecified one (32 bit) depending on your OS version. There is only one binary of RabbitMQ that is fully cross platform, i.e. no change between 32 bit and 64 bit.

Get those running and you have the latest and best of both packages which are both under very active development.

That is the simplest way when you take into account the future problems that you will avoid.

Personally I would also recommend keeping mission critical application packages outside of the usual Linux filesystem layout. Whether you choose to put them in /opt, or /home/erlang or /apps or /packages doesn't matter. The important thing is to take full control of these packages and don't let the OS package manager drive your decision making.

You might want to uninstall / remove the existing erlang-nox:

sudo apt-get remove erlang-nox

And then install rabbitmq-server (which will install the required erlang-nox). However, it will be a good idea to check whether the uninstallation / removal of the current version of erlang-nox does not break something else that is installed on your box.

If Mudaser Ali answer doesn't help, then you can use the below steps. It worked for me. Please note that this answer is for ubuntu precise.

Download debain from http://www.rabbitmq.com/install-debian.html, but don't run it

Open /etc/apt/sources.list and add the below line in it

deb http://packages.erlang-solutions.com/ubuntu precise contrib

Then execute the below commands

wget http://packages.erlang-solutions.com/ubuntu/erlang_solutions.asc
sudo apt-key add erlang_solutions.asc
sudo apt-get update
sudo apt-get install erlang
sudo apt-get install erlang-nox
sudo dpkg -i rabbitmq-server_3.2.1-1_all.deb
