Installs the Percona MySQL client and/or server components. (We are attempting to leverage the official Opscode MySQL cookbook as much as possible.)
Optionally installs:
- XtraBackup hot backup software
- Percona Toolkit advanced command-line tools
- XtraDB Cluster high availability and high scalability solution for MySQL. {DEPRECATED}
- Percona Monitoring Plugins various Nagios plugins for monitoring MySQL
We provide an expanding set of tests against the following 64-bit platforms:
- Ubuntu Precise 12.04 LTS
- Centos 6.4
Although we don't test against all possible platform verions, we expect the following to be supported. Please submit an issue if this is not the cause, and we'll make reasonable efforts to improve support:
- Ubuntu
- Debian
- Amazon Linux AMI
- CentOS
- Red Hat
- Scientific
- Fedora
We aim to test the most recent releases of Chef 10 and 11. You can view the currently tested versions. (Feel free to submit a pull request if they're out of date!)

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

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