This section uses docker to install RabbitMQ. The image used is bitnami. Bitnami is a company that provides Docker images and software packages for various popular applications. Using docker, we can run the program we want to install in 3 minutes. I have to say it’s really convenient. Okay, let’s get started. Prerequisites for use: Linux virtual machine and docker environment installed. If docker is not installed, please refer here to install docker first.
1. Search for images
[root@localhost ~]# docker search rabbitmq NAME DESCRIPTION STARS OFFICIAL AUTOMATED rabbitmq RabbitMQ is an open source multi-protocol me… 4887 [OK] bitnami/rabbitmq Bitnami Docker Image for RabbitMQ 103 [OK]
Here we choosebitname/rabbitmq
2. Download the image
[root@localhost ~]# docker pull bitnami/rabbitmq Using default tag: latest latest: Pulling from bitnami/rabbitmq
3. Run the RabbitMQ image
docker run -d --name rabbitmq \ -e RABBITMQ_USERNAME=admin \ -e RABBITMQ_PASSWORD=admin \ -p 15672:15672 -p 5672:5672 -p 25672:25672 -p 61613:61613 -p 1883:1883 bitnami/rabbitmq
where RABBITMQ_USERNAME is the username
RABBITMQ_PASSWORD is the password
For more descriptions of environment variables, see the end of the article
4. Check the running effect
Check to see if the docker container has started successfully. You can see it is running below.
[root@localhost ~]# docker ps | grep rabbit 0d5cb60e3a06 bitnami/rabbitmq "/opt/bitnami/script…" 22 seconds ago Up 20 seconds 4369/tcp, 5551-5552/tcp, 0.0.0.0:1883->1883/tcp, :::1883->1883/ tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp, :::5672->5672/tcp, 0.0.0.0:15672->15672/tcp, :::15672->15672/tcp, 0.0. 0.0:25672->25672/tcp, :::25672->25672/tcp, 0.0.0.0:61613->61613/tcp, :::61613->61613/tcp, 15671/tcp rabbitmq
Enter the address to access the console
http://192.168.56.201:15672/#/
Username: admin, password admin
login successful
At this point, we can happily play with RabbitMQ
5. Description of environment variables
(Sourced from official website)
RABBITMQ_VHOST: RabbitMQ application vhost. Default: /
RABBITMQ_VHOSTS: List of additional virtual host (vhost), separated by space. E.g.: /shared /prioritized /tasks
RABBITMQ_USERNAME: RabbitMQ application username. Default: user

RABBITMQ_ERL_COOKIE: Erlang cookie to determine whether different nodes are allowed to communicate with each other.
RABBITMQ_NODE_TYPE: Node Type. Valid values: stats, queue-ram or queue-disc. Default: stats
RABBITMQ_NODE_NAME: Node name and host. E.g.: node@hostname or node (localhost won't work in cluster topology). Default rabbit@localhost. If using this variable, ensure that you specify a valid host name as the container wil fail to start otherwise. If using a fully qualified domain name, RABBITMQ_USE_LONGNAME needs to be set to true as well.
RABBITMQ_USE_LONGNAME: When set to true this will cause RabbitMQ to use fully qualified names to identify nodes. Default: false
RABBITMQ_FORCE_BOOT: Force a node to start even if it was not the last to shut down. Default: no
RABBITMQ_CLUSTER_NODE_NAME: Node name to cluster with. E.g.: clusternode@hostname

RABBITMQ_SSL_KEYFILE: Path to the RabbitMQ server SSL certificate key file. No defaults.
RABBITMQ_COMBINED_CERT_PATH: Cert- and keyfile are combined automatically into one combined file at this file path. If you are using a combined certificate anyways, mount it to the container and set this path to the mounted file. Default: /tmp/rabbitmq_combined_keys.pem
RABBITMQ_SSL_DEPTH: Maximum number of non-self-issued intermediate certificates that may follow the peer certificate in a valid certification path. No defaults.
RABBITMQ_SSL_FAIL_IF_NO_PEER_CERT: Whether to reject TLS connections if client fails to provide a certificate. Default: verify_none

Memory and disk configuration
RABBITMQ_VM_MEMORY_HIGH_WATERMARK: High memory watermark for RabbitMQ to block publishers and prevent new messages from being enqueued. Can be specified as an absolute or relative value (as percentage or value between 0 and 1). No defaults.
RABBITMQ_DISK_FREE_RELATIVE_LIMIT: Disk relative free space limit of the partition on which RabbitMQ is storing data. Default: 1.0

6. Enter the RabbitMQ container to find out
First enter the container
[root@localhost ~]# docker exec -it rabbitmq bin/bash
rabbitmq depends on the erlang environment, so check whether erlang is installed successfully
Enter erl, you can see the following output
```bash I have no name!@0d5cb60e3a06:/$ erl Erlang/OTP 24 [erts-12.2] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [jit] Eshell V12.2 (abort with ^G) 1>
bitnami image, the software is generally installed in the opt/bitnami directory

Check whether rabbitmq starts normally
rabbitmqctl status can output a lot of rabbitmq information
Including version information, installed plug-ins, data installation directory, and some indicator information.

7. Extended reading
When playing with containers, when searching for images, you will find that the images in the bitnami warehouse have relatively high stars. Found it really useful!
