Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

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


Supported Platforms

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

  • Ubuntu
  • Debian
  • Amazon Linux AMI
  • CentOS
  • Red Hat
  • Scientific
  • Fedora


  • apt Opscode LWRP Cookbook
  • openssl Opscode Cookbook
  • yum Opscode LWRP Cookbook


It is recommended to use a version of Chef >= 10.16.4 as that is the target of my usage and testing, though this should work with any version >= 10.0.0.


  • percona - The default no-op recipe.
  • percona::package_repo - Sets up the package repository and installs 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::configure_server - Used internally to manage the server configuration.
  • percona::replication - Used internally to grant permissions for replication.
  • percona::access_grants - Used internally to grant permissions for recipes.
  • percona::monitoring - Installs Percona monitoring plugins for Nagios


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

Encrypted Passwords

This cookbook requires Encrypted Data Bags. If you forget to use them or do not use a node attribute to overwrite them empty passwords will be used.

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. Please refer to the official documentation on how to get this setup. It actually uses a MySQL example so it can be mostly copied. Ensure you cover the data bag items as described below.

mysql item

The mysql item should contain entries for root, backup, and replication. 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.


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):

slow_query_log_file = /var/lib/mysql/data/mysql-slow.log

Dynamically setting the bind address

There's a special attribute node['percona']['server']['bind_to'] that allows you to dynamically set the bind address. This attribute accepts the values 'public_ip', 'private_ip', 'loopback', or and interface name like 'eth0'. Based on this, the recipe will find a corresponding ipv4 address, and override the node['percona']['server']['bind_address'] attribute.
