Description

Installs the Percona MySQL client and/or server components. Optionally installs:

Requirements

Supported Platforms

The following platforms are supported by this cookbook, meaning that the recipes run on these platforms without error:

  • Ubuntu
  • Debian

Cookbooks

  • apt Opscode LWRP Cookbook

Recipes

  • percona - The default recipe. This sets up the apt repository and install common packages.
  • percona::client - Installs the Percona MySQL client libraries.
  • percona::server - Installs and configures the Percona MySQL server daemon.
  • percona::backup - Installs and configures the Percona XtraBackup hot backup software.
  • percona::toolkit - Installs the Percona Toolkit software
  • percona::cluster - Installs the Percona XtraDB Cluster server components
  • percona::replication - Used internally to grant permissions for replication.
  • percona::access_grants - Used internally to grant permissions for recipes.

Usage

This cookbook installs the Percona MySQL components if not present, and pulls updates if they are installed on the system.

Encrypted Passwords

This cookbook supports Encrypted Data Bags.

To use encrypted passwords, you must create an encrypted data bag. This cookbook assumes a data bag named passwords, but you can override the name using the node[:percona][:encrypted_data_bag] attribute.

This cookbook expects a mysql item and a system item.

mysql item

The mysql item should contain entries for root, backup, and replicaiton. If no value is found, the cookbook will fall back to the default non-encrypted password.

system item

The "system" item should contain an entry for the debian system user as specified in the node[:percona][:server][:debian_username] attribute. If no such entry is found, the cookbook will fall back to the default non-encrypted password.

Example: "passwords" data bag - this example assumes that node[:percona][:server][:debian_username] = spud

{
  "mysql" :
  {
    "root" : "trywgFA6R70NO28PNhMpGhEvKBZuxouemnbnAUQsUyo=\n"
    "backup" : "eqoiudfj098389fjadfkadf=\n"
    "replication" : "qwo0fj0213fm9020fm2023fjsld=\n"
  },
  "system" :
  {
    "spud" : "dwoifm2340f024jfadgfu243hf2=\n"
  }
}

Above shows the encrypted password in the data bag. Check out the encrypted_data_bag_secret setting in knife.rb to setup your data bag secret during bootstrapping.

Explicit my.cnf templating

In some situation it is preferable to explicitly define the attributes needed in a my.cnf file. This is enabled by adding categories to the node[:percona][:conf] attributes. All keys found in the node[:percona][:conf] map will represent categories in the my.cnf file. Each category contains a map of attributes that will be written to the my.cnf file for that category. See the example for more details.

Example:

node["percona"]["conf"]["mysqld"]["slow_query_log_file"] = "/var/lib/mysql/data/mysql-slow.log"

This configuration would write the mysqld category to the my.cnf file and have an attribute slow_query_log_file whose value would be /var/lib/mysql/data/mysql-slow.log.

Example output (my.cnf):

[mysqld]
slow_query_log_file = /var/lib/mysql/data/mysql-slow.log
