Chef wrapper cookbook to create master, slaves, and sentinel redis server setups. This wrapper should work on all Debian and RHEL platform family OS's.
Cookbook works as a wrapper around the community redisio cookbook to allow for the creation of master/slave and sentinel systems.
The cookbook utilizes three recipes depending on the server's role.
default.rb : calls upstream rediosio::default
enable.rb : calls upstream redisio::enable
master.rb : sets up a redis server and init script with master in name
slave.rb : sets up a slave redis server pointing to the master node
definded within attributes.
Search will look for the node in the same environment with the tag
redis_master and set slaveof replication to that node. If you do not want to
use search, create the master node first before bootstrapping, and set the
attribute ['redis-multi']['master'] with the correct IP.
slave.rb : sets up a slave redis server pointing to the master node
definded within attributes.
Search will be used in the same fashion as the redis_slave.rb recipe above (
they share the _find_master.rb functionality.)
Note that find_all.rb is included here as a recipe. This is done in case a
wrapper cookbook wants to find all redis nodes for iptables or some other
purpose.
default['redis-multi']['master'] = nil Used to identify a master IP address.
This value will be populated after first run using search and a redis_master
tag.
default['redis-multi']['slaves'] = %w() Used to hold a list of slave IP
addresses that is populated through search and a redis_slave tag.
** Note that the two settings below only apply if you don't define your own
node[redisio] instances of redis (if you call the recipe without doing that,
these ports will be used as the defaults for new instances)
default['redis-multi']['bind_port'] = 6379 Used for the port for masters,
slaves, and sentinels. Right now, this must be the same everywhere. To override
ports, and make them different on different nodes, you will have to use upstream
directly.
default['redis-multi']['sentinel_port'] = 46379 Used to specify an alternate
default port for sentinel instances.
