rabbitmqcluster

Ansible Playbook to deploy RabbitMQ cluster in docker containers launched with Vagrant. The RabbitMQ cliuster is based on one master and two slaves

The cluster configuration based on this document: https://www.rabbitmq.com/clustering.html

Requirements

• Vagrant and Virtualbox must be installed on your host ( physical host as Node are build from 64bit image )

Getting Started

This deployement script use the role ansible-role-docker created by githubixx in order to install Docker components on the Nodes.

To run mysql in master and slave replication :

1. Download and Install VirtualBox
2. Download and Install Vagrant
3. Download the repo or use git to clone in your home directory: git clone https://github.com/ghassencherni/rabbitmqcluster.git
4. Add the entry “10.0.0.2 Node1” in your hosts file ( /etc/hosts for linux , C:\Windows\System32\drivers\etc\hosts for windows10 )
5. Move to the downloaded repo : cd rabbitmqcluster
6. Run the command “vagrant up” : this will run a VM with 3 rabbitmq instances containers, one master and 2 slaves deployed by Ansible

Note: The admin interface of the rabitmq master run isis accessible on port 15672, you can modify this port on the Vagranfile and use port 80 instead for example. The IP address of the created VM is “10.0.0.2” you can change it in the Vagrantfile if needed.

How to test the deploy :

1. Open the URL : http://node1:15672/ in the browser
2. Put the user: admin and the password : "pasword" (default values) If every things is ok, you get the dashboard with three nodes as shown below: (https://www.howtoforge.com/images/how_to_set_up_rabbitmq_cluster_on_ubuntu_1804_lts/big/9.png)

Note: This VM uses 2 GB of RAM by default, you might want to manually change the memory requirements to a higher value (the v.memory parameter in the Vagrantfile).
