The aim of this project is to deploy a simple Cassandra cluster on Vagrant with some default configuration.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
What things you need to run this Ansible playbook :
- Vagrant must be installed on your computer
- Update the Vagrant file based on your computer (CPU, memory), if needed
- You must have download the ubuntu Xenial64 vagrant box :
vagrant box add https://app.vagrantup.com/ubuntu/boxes/xenial64
A good point with Vagrant is that you can create, update and destroy all architecture easily with some commands.
Be aware that you need to be in the Vagrant directory to be able to run the commands.
Vagrant needs to init the project to run and build it :
vagrant up
After build, you can check which virtual machine Vagrant has created :
vagrant status
If all run like it is expected, you should see something like this :
$ vagrant status
Current machine states:
cassandra01 running (virtualbox)
cassandra02 running (virtualbox)
cassandra03 running (virtualbox)
To deploy the Cassandra cluster, you just have to run the Ansible playbook cassandra.yml with this command :
ansible-playbook cassandra.yml
If everything run as expected, you should connect to the server and check the status of Cassandra cluster with that command :
$ sudo nodetool status
