morpheus_ha_ansible

This is a repo of Ansible roles that allows you to provision a High Availablility Morpheus application.

Architecture

• 2 App servers
• Odd Number Elasticsearch nodes (will support additional nodes)
  • single node implementations not supported
• Odd Number RabbitMQ nodes (will support additional nodes)
  • single node implementations not supported
• Odd Number Percona XtraDB Cluster Nodes (will support additional nodes)
  • single node implementations not supported

Assumptions:

• CentOS 7 only (right now)
• Entirely separated services (right now)
• A valid loadbalancer/VIP for RabbitMQ has been configured
  • Ports and server mappings for ports 5672 and 61613
• A valid loadbalancer/VIP for application tier servers has been configured
  • Ports and server mappings for ports 443 and 80

Getting Started

The host groups for the hosts file are the only place that configuration needs to occur

Here is an example of a valid hosts file including the requisite groups:

[rabbit_cluster]
52.52.27.6 ansible_user=slimshady
13.56.104.200 ansible_user=slimshady
54.241.108.245 ansible_user=slimshady

[elastic_cluster]
13.56.44.24 ansible_user=slimshady
54.215.121.50 ansible_user=slimshady
13.57.169.119 ansible_user=slimshady

[db]	
52.9.94.143 ansible_user=slimshady
52.9.226.166 ansible_user=slimshady
52.8.96.0 ansible_user=slimshady

[morpheus]
13.57.66.216 ansible_user=slimshady
52.52.2.76 ansible_user=slimshady

Once this has been configured it is very straightforward to run the morpheus.yml playbook on these hosts:

slimshady@localhost:~$ ansible-playbook -i /path/to/hosts morpheus.yml
