Ansible playbook to install Elasticsearch on CentOS 7

Install Ansible

First off, create a new virtual Python 2.7 environment to install Ansible and dependencies in by running the following command:

$ virtualenv venv

Then, activate the environment by running:

$ source venv/bin/activate

Then, use pip to install Ansible and dependencies:

$ pip install -r requirements.txt

Then lastly, run ansible --version to confirm that Ansible is installed correctly.

Create the inventory file

Copy the hosts file in the inventory/development folder into a new subfolder in the inventory folder.

Open up the file with your favourite text editor and change the three lines starting with IP addresses. Add or remove lines as needed to fit your collection of hosts.

Change the ansible_user and ansible_private_key_file as needed. If your SSH key is already on the remote host, then you can remove the ansible_private_key_file. Same goes for ansible_user, if you have a matching user on the remote host.

Run the playbook

$ ansible-playbook -i inventory/development playbook.yml

This installs Oracle Java JRE and Elasticsearch.
