How to install RabbitMQ on Mac using Homebrew

In this tutorial, we will learn to install RabbitMQ on Mac using Homebrew.

RabbitMQ is an open source message broker software. It is lightweight and easy to deploy. It supports AMQP (Advanced Message Queuing Protocol), STOMP (Streaming Text Oriented Messaging Protocol), MQTT (Message Queuing Telemetry Transport) and other protocols.

Alright, let's install RabbitMQ on Mac using Homebrew.

Step 1: Install Homebrew

Homebrew is "The missing package manager for macOS".

Installing applications and packages using Homebrew on Mac is super easy. I will recommend you to use Homebrew if you are a developer and use Mac for dev work.

Okay, open Terminal and type the following command.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Once you have Homebrew installed on your Mac, type the following command to check the version.

$ brew -v

At the time of writing this tutorial I was using v2.0.1.

$ brew -v
Homebrew 2.0.1
Homebrew/homebrew-core (git revision c0b41; last commit 2019-02-13)

Already have Homebrew?

If you already have Homebrew installed on your Mac then run the following command to update it.

$ brew update

This will update the packages. If you have the latest updates then you will get the following output.

$ brew update
Already up-to-date.

Step 2: Install RabbitMQ using Homebrew

Now, run the following command in Terminal to install RabbitMQ.

$ brew install rabbitmq

Step 3: Add to PATH

RabbitMQ server and CLI script are installed under /usr/local/sbin. Add this to PATH.

export PATH=$PATH:/usr/local/sbin

I have added the following to .bash_profile file.

$ cd
$ vi .bash_profile

Inside the .bash_profile file.

#HOMEBREW RABBITMQ
export HOMEBREW_RABBITMQ=/usr/local/Cellar/rabbitmq/3.7.11/sbin/
export PATH=$PATH:$HOMEBREW_RABBITMQ

Where are the RabbitMQ server and CLI tools present?

RabbitMQ server and CLI tools are generally inside /usr/local/Cellar/rabbitmq/{version}/sbin/ directory.

On my Mac the RabbitMQ server and CLI tools are present inside the /usr/local/Cellar/rabbitmq/3.7.11/sbin/ directory.

YUSUF-MBP:~ yusufshakeel$ cd /usr/local/Cellar/rabbitmq/3.7.11/sbin/
YUSUF-MBP:sbin yusufshakeel$ ls -la

-r-xr-xr-x   1 yusufshakeel  admin    1235 Jan 31 23:15 rabbitmqctl

Step 4: Start RabbitMQ server

To start the RabbitMQ run the following command.

$ rabbitmq-server

  ##  ##

                    /usr/local/var/log/rabbitmq/rabbit@localhost_upgrade.log

              Starting broker...
 completed with 6 plugins.

Step 5: Access dashboard

We can access RabbitMQ web dashboard by going to http://localhost:15672 so, open the link in your favourite browser.

The default username and password is guest and guest respectively.


RabbitMQ login

Step 6: Stop RabbitMQ server

To stop RabbitMQ press Ctrl + C.

$ rabbitmq-server

Possible errors

We may get an error like The `brew link` step did not complete successfully when trying to install RabbitMQ.

$ brew install rabbitmq

The formula built, but is not symlinked into /usr/local

You can try again using:
  brew link rabbitmq
==> Caveats
Management Plugin enabled by default at http://localhost:15672

Bash completion has been installed to:
  /usr/local/etc/bash_completion.d

To have launchd start rabbitmq now and restart at login:
  brew services start rabbitmq
Or, if you don't want/need a background service you can just run:
  rabbitmq-server
==> Summary
  /usr/local/Cellar/rabbitmq/3.7.11: 235 files, 13.8MB, built in 10 seconds

To fix this we have to run the following command.

$ brew link rabbitmq
Linking /usr/local/Cellar/rabbitmq/3.7.11... 
Error: Could not symlink sbin/cuttlefish
/usr/local/sbin is not writable.

We get the error /usr/local/sbin is not writable message.

This is because /usr/local/sbin directory is not present. So, go to /etc/paths.d directory and created a file named usr_local_sbin and write the path /usr/local/sbin inside the file and save it.

$ cd /etc/paths.d/
$ sudo vi usr_local_sbin

Inside usr_local_sbin file:

/usr/local/sbin

Now, create /usr/local/sbin directory.

$ cd /usr/local
$ sudo mkdir sbin

$ ls -la
drwxr-xr-x    2 root          wheel    64 Feb 18 18:06 sbin

Now change the ownership. Type whoami to get your username. Mine is yusufshakeel so, I will use the following.

$ sudo chown yusufshakeel:admin sbin

$ ls -la
drwxr-xr-x    2 yusufshakeel  admin    64 Feb 18 18:06 sbin

Now run the brew link rabbitmq command.

$ brew link rabbitmq
Linking /usr/local/Cellar/rabbitmq/3.7.11... 23 symlinks created

Linking is done!
