Requirements

• Ansible
• Java 8

Configure

Refer the file inventories/opendistro/group_vars/all/all.yml to change the default values for elasticsearch and kibana Installation.

For example we need to increase the java memory heap size for elasticsearch,

xms_value: 8
xmx_value: 8

By default, it will install five nodes elasticsearch cluster with respective roles (3 master, 5 data and 2 ingest nodes).

es1 ansible_host=10.0.1.1 ip=10.0.1.1 roles=data,master
es2 ansible_host=10.0.1.2 ip=10.0.1.2 roles=data,master
es3 ansible_host=10.0.1.3 ip=10.0.1.3 roles=data,master
es4 ansible_host=10.0.1.4 ip=10.0.1.4 roles=data,ingest
es5 ansible_host=10.0.1.5 ip=10.0.1.5 roles=data,ingest

Note: You need to add additional nodes details in inventories/opendistro/hosts file for creating elasticsearch cluster with different node sizes.

For example, if you want to create seven nodes cluster with two additional data nodes (es6 and es7) then you need to add the below entries.

es6 ansible_host=10.0.1.6 ip=10.0.1.6 roles=data
es7 ansible_host=10.0.1.7 ip=10.0.1.5 roles=data

You can mention the elasticsearch node roles details in roles parameter.

You can also change the elasticsearch and kibana versions. Please refer the version compatibility with Open Distro.

Refer the file inventories/opendistro/group_vars/all/opendistro.yml to change the default values for Open Distro installation.

You can customize the opendistro plugins installation by enable or disable it in config file opendistro.yml

opendistro_security_install: false
opendistro_security_install_kibana: false

Note: By default, all the above mentioned plugins will be installed.

You can set the reserved users(admin and kibanaserver) password using admin_password and kibanaserver_password variables.

Install

Ansible

# Deploy with ansible playbook - run the playbook as root
ansible-playbook -i inventories/opendistro/hosts opendistro.yml

It will install and configure the elasticsearch and kibana with opendistro. Once the deployment completed, you can access the kibana with user admin and password which you provided for variable admin_password(Default password: Test@123).
