percona-multi

Chef wrapper cookbook to create Percona master/slave server setups. This wrapper
should work on all Debian and RHEL platform family OS's.

Utilization

This cookbook works as a wrapper around the community Percona cookbook to allow
for the creation of master/slave and master/multi-slave Percona systems.

This cookbook utilizes two recipes depending on the server's defined role.

master.rb : sets up a master Percona server and creates replicant users for each
slave node defined within the attributes

slave.rb : sets up a slave Percona server pointing it to the master node defined
within attributes.

There is no search function within this cookbook. The IP addresses of the master
and slave nodes must be defined in attributes before it will converge.

Keep in mind that passwords have to be set via encrypted data bags as outlined
in the percona cookbook

There is no search function within this cookbook. The IP addresses for the servers
has to be set as attributes and build order becomes important.Your orchestration
layer should build the servers, then the IP addresses should be set as attributes,
then the master node should then be converged prior to converging the slave nodes.

Attributes

Local attributes --

['percona']['master'] : sets the IP address that defines the master node

['percona']['slaves'] : is any array that defines the IP address(es) of
the slave node(s).

Percona cookbook attributes to be aware of --

['percona']['server']['bind_to'] : should be set to "private_ip" vice default of
"public_ip" to ensure Percona is listening on the internal IP's only.
