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

This cookbook works as a wrapper around the community MySQL cookbook(version 5.x only) to allow for the creation of master/slave and master/multi-slave MySQL systems.

*** Special Note: This cookbook only supports MySQL community recipe version 5.x, due to version 6.x changes causing major compatibility issues.

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

mysql_master.rb : sets up a master MySQL server and creates replicant users for each slave node definded within attributes.

Search will look for the node(s) in the same environment with the tag mysql_slave and grant the allowed replicating node(s). If you do not want to use search, create the slave node(s) first before bootstrapping, and set the attribute ['mysql-multi']['master'] with the correct IP array.

mysql_slave.rb : sets up a slave MySQL server pointing to the master node definded within attributes.

Search will look for the node in the same environment with the tag mysql_master and set master replication to that node. If you do not want to use search, create the master node first before bootstrapping, and set the attribute ['mysql-multi']['master'] with the correct IP.

['mysql-multi']['master'] : sets the IP address that defines the master node

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

['mysql-multi']['slave_user'] : allows for the setting of a custom name for the slave MySQL user, by default it is set to 'replicant'.

['mysql-multi']['server_repl_password'] : is set to match

['mysql-multi']['bind_ip'] is an override for the logic that determines the best bind_address for mysql. Allowing you to set it to whatever is needed for your specific configuration.
