RabbitMQ is an open source message broker software that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since evolved to support multiple messaging protocols. It is widely used for handling asynchronous communication or messaging in distributed systems. To ensure compatibility, performance, and security, it's crucial to know which version of RabbitMQ is currently running in your environment.
How to Verify the Version of RabbitMQ
Using the Command Line Interface
One of the most straightforward methods to check the version of RabbitMQ is by using the command line on the server where RabbitMQ is installed.
- For users running RabbitMQ on Linux or macOS, open your terminal.
- For Windows users, you should open your Command Prompt or PowerShell.
Type the following command:
This command will display a range of information about the RabbitMQ server, including its version. The output typically includes details like the RabbitMQ version, Erlang version, Uptime, Nodes, and various settings related to the message broker. Look for a section similar to this:
Here, "3.8.5" indicates the version of RabbitMQ.
Checking the Version Through the Management Interface
If you have RabbitMQ Management Plugin installed, you can also check the version through the web-based management interface:
- Open your web browser.
- Navigate to
http://{your-rabbitmq-server}:15672/- replace{your-rabbitmq-server}with the hostname or IP of your RabbitMQ server. The default management port is15672. - Log in using your credentials.
- Once logged in, the overview tab typically shows the RabbitMQ version at the top of the page.
Using Docker
If you are running RabbitMQ in a Docker container, you can execute the following command to check the version:
Replace <container_name> with the name or ID of your RabbitMQ container.
Summary Table of Methods to Verify RabbitMQ Version
| Method | Command/Instruction | Description |
| CLI | rabbitmqctl status | Direct command to fetch status including RabbitMQ version |
| Management Interface | Access http://{your-rabbitmq-server}:15672/ and check the overview tab. | Web-based check via RabbitMQ Management Plugin |
| Docker | docker exec <container_name> rabbitmqctl status | Checking version inside a Docker container |

Importance of Updating RabbitMQ
It's important to periodically check and update your RabbitMQ version to:
- Enhance security with patches and updates.
- Gain performance improvements and new features.
- Maintain compatibility with updates in dependent services or libraries, like Erlang.
Compatibility with Erlang
RabbitMQ requires Erlang to run. Each version of RabbitMQ supports specific versions of Erlang. Ensure that the Erlang version installed on your system is compatible with your RabbitMQ version. Incompatibilities can lead to performance issues or unexpected failures.
For instance, as of RabbitMQ version 3.8.5, you should be using one of the supported Erlang versions, which can be found in the RabbitMQ documentation or release notes.
Conclusion
Verifying the version of RabbitMQ running in your system is crucial for system maintenance and troubleshooting. It helps ensure that your installation is up to date with the latest features and security patches, and it assists in diagnosing issues related to version compatibility with other software components. Whether through command line tools, management interfaces, or a Docker environment, maintaining awareness of your RabbitMQ version is an important aspect of managing message-oriented middleware.
