Table of Contents
Overview
puppet-mha installs and configures a MHA (Mysql High Availability) cluster
Module Description
This module is composed by the manager and the node. The node class is really simple, it just installs some helper on the mysqld machine, while the manager is where the magic happens. puppet-mha helps you installing all the packages, configuring multiple MHA instances, giving SSH access to the nodes etc.
Usage
How to install a manager
$servers_hash = { 'server01' => { 'hostname' => 'my-server-01' },
'server02' => { 'hostname' => 'my-server-02',
'skip_reset_slave' => 1 }
}
mha::instance { 'my_cluster':
servers => $servers_hash,
mysql_password => 'foo',
mysql_repl_password => 'bar',
ssh_key_priv => 'ashdkshaksahdkj',
ssh_key_pub => '3j234324jn',
online_change_script => 'profiles/mha/mha_online_change.sh.erb'
}
Keep in mind that online_change_script and all the other scripts parameters must point to a template YOU have to implement. MHA gives you 100% flexibility about that and so do we.
How to install a node
include mha::node
Bottom line
This module is thought with the Hiera/create_resource pattern in mind, but you can use it happily without hiera and doing all the dirty work in your manifest.
Limitations
This module is tested only on Debian 7 Wheezy and expects Puppet 3.7
