Role Variables

Want to install other versions of Redis:

• Put your redis_version variable in vars/main.yml
• Add checksum for your version to redis_checksums in vars/main.yml
• Add config template to template/[your version]/redis.conf.j2

Add these variables to set up cluster:

---
# set up cluster
setup_cluster: yes

# set up cluster through this node
master_ip: 10.240.0.5
master_port: 7000

# all nodes except the master node above
cluster_nodes:
- { node_ip: 10.240.0.12, node_port: 7000}
- { node_ip: 10.240.0.17, node_port: 7000}
- { node_ip: 10.240.0.12, node_port: 7001}
- { node_ip: 10.240.0.17, node_port: 7001}
- { node_ip: 10.240.0.5, node_port: 7001}

# assign hash slots to each master node
cluster_slots:
- { ip: 10.240.0.12, port: 7000, from: 0, to: 5400}
- { ip: 10.240.0.17, port: 7000, from: 5401, to: 10800}
- { ip: 10.240.0.5, port: 7000, from: 10801, to: 16383}

- {ip: 10.240.0.17, port: 7000}
- {ip: 10.240.0.5, port: 7000}

# assign slave nodes to their master nodes

- {ip: 10.240.0.17, port: 7001, master_ip: 10.240.0.12, master_port: 7000}
- {ip: 10.240.0.5, port: 7001, master_ip: 10.240.0.17, master_port: 7000}
