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.
Note that once a master has been discovered, it will no longer be automatically
changed to new masters as they are deployed. If a new master is installed, or
the existing master is deleted, you must manually set a new master for existing
slaves by editing the ['mysql-multi']['master'] attribute as described below.
['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.
