Ansible role for Elasticsearch and its installation on CentOS 7

In our previous article, we discussed how to install elasticsearch on CentOS 7. Having the ability to install elasticsearch from a single command is a wonderous thing. So, in this post, we will see elasticsearch installation using Ansible playbook or role to do just that.

Also we have already discussed regarding how to create Ansible Playbooks and Ansible Roles, so lets jump directly into the usage and examples of Ansible Roles/Playbooks.

 

Install Elasticsearch with Ansible

We have already created and submitted Ansible Role to install elasticsearch to Ansible Galaxy, so in this section we will see how to get download role from ansible galaxy into your work-space and how we can use it.
Install or download from Ansible Galaxy:

[ansible@localhost ~]$ ansible-galaxy install avinash6784.elasticsearch -p ./roles

See Ansible Galaxy help for more options

[ansible@localhost ~]$ ansible-galaxy --help

Download from direct github:
Download manually from github like as below,

[ansible@localhost ~]$ git clone https://github.com/avinash6784/ansible-role-elasticsearch.git

The code should reside in the roles directory of your ansible playbooks work-space. ( See ansible documentation for more information on roles ), in a folder elasticsearch.
Run the playbook: 
First create a playbook like as below,

[ansible@localhost ~]$ vim test.yml
- name: Install Elasticsearch
  hosts: localhost
  become: true
  roles:
    - elasticsearch
[ansible@localhost ~]$ ansible-playbook -i hosts test.yml

For more detail information regarding usage of above ansible role of elasticsearch, please visit GitHub Repo README.
