Module: REDIS

Redis Identity

Redis are required parameters when defining a Redis cluster.

• redis_cluster: Redis cluster name, top-level namespace for cluster sources.
• : Redis node identity, integer the number of the node in the cluster.
• redis_instances: A Dict with the Key as redis port and the value as a instance level parameters.

Redis Mode

There are three available in Pigsty:

• standalone: setup redis as standalone (master-slave) mode
• sentinel: setup redis as sentinel for standalone redis HA

Redis Definition

Here are three examples:

Limitation

• A redis node can only belong to one redis cluster
• You can not set different password for redis instances on same redis node (since redis_exporter only allows one password)

• : create redis cluster / node / instance
• redis-rm.yml: remove redis cluster /node /instance

You can also create & destroy redis cluster/node/instance with util scripts:

bin/redis-add 10.10.10.10       # create redis node '10.10.10.10'
bin/redis-add 10.10.10.10 6501  # create redis instance '10.10.10.10:6501'
bin/redis-rm 10.10.10.10        # remove redis node '10.10.10.10'
bin/redis-rm 10.10.10.10 6501   # remove redis instance '10.10.10.10:6501'

Init Cluster/Node/Instance

You can also use wrapper script:

bin/redis-add 10.10.10.10       # create redis node '10.10.10.10'
bin/redis-add 10.10.10.10 6501  # create redis instance '10.10.10.10:6501'

Remove Cluster/Node/Instance

You can also use wrapper script:

bin/redis-rm redis-ms          # remove redis cluster 'redis-ms'
bin/redis-rm 10.10.10.10       # remove redis node '10.10.10.10'
bin/redis-rm 10.10.10.10 6501  # remove redis instance '10.10.10.10:6501'

There are three dashboards for module.
