How to install RabbitMQ on Ubuntu 22.04

RabbitMQ is an open-source message broker software. It’s a software where queues are defined and to which applications connect in order to transfer a message or messages. Think of it as a middle man who acts as a broker. They can be used to reduce loads and delivery times for web application servers by delegating tasks that take up a lot of resources and or time to a third party that has no other job

Reasons for Using RabbitMQ

Message queueing allows web servers to respond to requests quickly instead of being forced to perform resource-heavy procedures on the spot that may cause delays.

Message queueing is important when you want to distribute a message to multiple consumers and also to balanced loading between worker nods.

Installing RabbitMQ 3.9 on Ubuntu 22.04

RabbitMQ is included in Ubuntu repositories but it lacked behind in terms of version releases. It is not the updated version because it takes longer to be updated.

1. Update system repositories

We need to start off by updating our repositories to make them up to date.

sudo apt update && apt upgrade -y 

2. Install Erlang

Erlang/OTP platform is a complex system consisting of many smaller modules. RabbitMQ requires Erlang to operate.

Let’s start by adding Erlang to the repository manually. Use the following commands:

sudo dpkg -i erlang-solutions_2.0_all.deb

Next, we need to add Erlang public key to the apt-secure repository.

sudo apt-key add erlang_solutions.asc

Lastly is to install Erlang but first run the system update again for the changes to take effect.

sudo apt update
sudo apt install erlang -y

3. Install RabbitMQ on Ubuntu 22.04

Now that we have satisfied all the requirements, we can now install RabbitMQ found on Ubuntu repositories with the following command.

sudo apt install rabbitmq-server -y

You will get the following output.

The following NEW packages will be installed:
  rabbitmq-server socat
0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 15.5 MB of archives.
After this operation, 24.3 MB of additional disk space will be used.

Use apt cache-policy rabbitmq-server to check your installed RabbitMQ.

apt cache-policy rabbitmq-server 

You will see the following output.

  Installed: 3.9.13-1
  Candidate: 3.9.13-1
  Version table:
 *** 3.9.13-1 500
        500 jammy/main amd64 Packages
        100 /var/lib/dpkg/status

4. Configuring RabbitMQ

After installation is complete, we now need to do some configuration on RabbitMQ.

First, start the RabbitMQ service with the following command.

sudo systemctl start rabbitmq-server

Check the status if RabbitMQ is running with the following command:

$ sudo systemctl status rabbitmq-server
● rabbitmq-server.service - RabbitMQ Messaging Server
     Loaded: loaded (/lib/systemd/system/rabbitmq-server.service; enabled; vendor preset: enabled)
     Active: active (running) since Fri 2022-04-29 19:38:53 UTC; 2min 35s ago
   Main PID: 17434 (beam.smp)
      Tasks: 21 (limit: 1119)
     Memory: 108.8M
        CPU: 8.051s
     CGroup: /system.slice/rabbitmq-server.service

             ├─17445 erl_child_setup 65536
             ├─17492 inet_gethost 4
             └─17493 inet_gethost 4
lines 1-12/12 (END)

Enable RabbitMQ on boot so that you don’t need to start every time when you reboot your system.

sudo systemctl enable rabbitmq-server

5. Enable RabbitMQ dashboard. (Optional)

You can enable dashboard management for RabbitMQ with the following command.

sudo rabbitmq-plugins enable rabbitmq_management

You will get the following output.

Enabling plugins on node [email protected]:
The following plugins have been configured:
Applying plugin configuration to [email protected]...
The following plugins have been enabled:

started 3 plugins.

You can now access the dashboard using http://<your-server-ip>:15672. but you will need to create admin user first.

15672 is the port RabbitMQ is served into.

You can create an admin login or you can use the quest if you only want to see what’s in it but if you want to do some operations, you will need to create the admin.

$ sudo rabbitmqctl add_user admin passwd
Adding user "admin" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.

$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
