This Ansible role installs an Apache SolrCloud cluster on Centos 7 boxes. It expects Java (tested with Java 8) is installed and a Zookeeper install is running.
To execute this role:
- Ansible 2.8.1 was used to write + test this role
- Java 8 installed on hosts
- Zookeeper (standalone or cluster) running on known IPs
- Networking is setup to allow VMs in cluster to communicate with each other
$ pipenv install -r test-requirements.txt --python 2.7
$ pipenv run molecule test
Create or add to your roles dependency file (e.g requirements.yml):
- src: tulibraries.ansible-role-solrcloud
name: solrcloud
Install the role with ansible-galaxy command:
ansible-galaxy install -r requirements.yml
Inventory:
[solr]
solrcloud-stage-01 ansible_host=192.168.138.179
solrcloud-stage-02 ansible_host=192.168.156.231
solrcloud-stage-03 ansible_host=192.168.199.175
Then run the playbook:
- name: Solrcloud cluster setup
hosts: solr
sudo: yes
roles:
- role: solrcloud
You need the following set in your playbook for your inventory(ies):
- zookeeper_hosts:
[zk_1_ip, zk_2_ip, zk_3_ip](an array of zookeeper host IPs; include ports if non-standard) - solr_collections:
{ 'collection1': { 'shards': 1, 'replicas': 2, 'shards_per_node': 1 } }(a dictionary of dictionaries for solrcloud collections to be created) - solr_collections_template_path:
{{ playbook_dir }}/templates/collections/(where the playbook can find the solr configs, in directories per collection defined above) - solr_collections_transfer_mode: copy or synchronize - basically, copy or rsync the above collection configurations to the hosts for then loading to Zookeeper
Other Variables are defined in defaults/main.yml.
