Description

Installs and configures MySQL client or server.

Requirements

Chef 0.10.10+.

Platform

• Debian, Ubuntu
• CentOS, Red Hat, Fedora
• Mac OS X (Using homebrew)

Tested on:

• Debian 5.0, 6.0
• Ubuntu 10.04-12.04
• CentOS 5.5-5.8, 6.2-6.3
• Mac OS X 10.7.2

Cookbooks

Requires Opscode's openssl cookbook for secure password generation. See Attributes and Usage for more information.

The RubyGem installation in the mysql::ruby recipe requires a C compiler and Ruby development headers to be installed in order to build the mysql gem.

Requires homebrew cookbook on Mac OS X.

Resources and Providers

The LWRP that used to ship as part of this cookbook has been refactored into the database cookbook. Please see the README for details on updated usage.

Attributes

See the attributes/server.rb or attributes/client.rb for default values. Several attributes have values that vary based on the node's platform and version.

• node['mysql']['client']['packages'] - An array of package names that should be installed on "client" systems. This can be modified, e.g., to specify packages for Percona.

• node['mysql']['server']['packages'] - An array of package names that should be installed on "server" systems. This can be modified, e.g., to specify packages for Percona.

• node['mysql']['auto-increment-increment'] - auto-increment-increment value in my.cnf

• node['mysql']['auto-increment-offset] - auto-increment-offset value in my.cnf

• node['mysql']['basedir'] - Base directory where MySQL is installed

• node['mysql']['bind_address'] - Listen address for MySQLd

• node['mysql']['conf_dir'] - Location for mysql conf directory

• node['mysql']['confd_dir'] - Location for mysql conf.d style include directory

• node['mysql']['data_dir'] - Location for mysql data directory

• node['mysql']['ec2_path'] - location of mysql data_dir on EC2 nodes

• node['mysql']['grants_path'] - Path where the grants.sql should be written

• node['mysql']['mysqladmin_bin'] - Path to the mysqladmin binary

• node['mysql']['old_passwords'] - Sets the old_passwords value in my.cnf.

• node['mysql']['pid_file'] - Path to the mysqld.pid file

• node['mysql']['port'] - Liten port for MySQLd

• node['mysql']['reload_action'] - Action to take when mysql conf files are modified. Also allows "reload" and "none".

• node['mysql']['root_group'] - The default group of the "root" user

• node['mysql']['service_name'] - The name of the mysqld service

• node['mysql']['socket'] - Path to the mysqld.sock file

• node['mysql']['use_upstart'] - Whether to use upstart for the service provider

Performance and other "tunable" attributes are under the node['mysql']['tunable'] attribute, corresponding to the same-named parameter in my.cnf, and the default values are used. See attributes/server.rb.

The following attributes are randomly generated passwords handled in the mysql::server recipe, using the OpenSSL cookbook's secure_password helper method. These are set using the set_unless node attribute method, which allows them to be easily overridden e.g. in a role.

• node['mysql']['server_root_password'] - Set the server's root password
• node['mysql']['server_repl_password'] - Set the replication user 'repl' password
• node['mysql']['server_debian_password'] - Set the debian-sys-maint user password

Windows Specific

The following attributes are specific to Windows platforms.

• node['mysql']['client']['version'] - The version of MySQL connector to install.
• node['mysql']['client']['arch'] - Force 32 bit to work with the mysql gem
• node['mysql']['client']['package_file'] - The MSI file for the mysql connector.
• node['mysql']['client']['url'] - URL to download the mysql connector.
• node['mysql']['client']['packages'] - Similar to other platforms, this is the name of the client package.
• node['mysql']['client']['basedir'] - Base installation location
• node['mysql']['client']['lib_dir'] - Libraries under the base location
• node['mysql']['client']['bin_dir'] - binary directory under base location
• node['mysql']['client']['ruby_dir'] - location where the Ruby binaries will be

Usage

On client nodes, use the client (or default) recipe:

{ "run_list": ["recipe[mysql::client]"] }

This will install the MySQL client libraries and development headers on the system.

On nodes which may use the database cookbook's mysql resources, also use the ruby recipe. This installs the mysql RubyGem in the Ruby environment Chef is using via chef_gem.

{ "run_list": ["recipe[mysql::client]", "recipe[mysql::ruby]"] }

If you need to install the mysql Ruby library as a package for your system, override the client packages attribute in your node or role. For example, on an Ubuntu system:

{
  "mysql": {
    "client": {
      "packages": ["mysql-client", "libmysqlclient-dev","ruby-mysql"]
    }
  }
}

This creates a resource object for the package and does the installation before other recipes are parsed. You'll need to have the C compiler and such (ie, build-essential on Ubuntu) before running the recipes, but we already do that when installing Chef :-).

On server nodes, use the server recipe:

{ "run_list": ["recipe[mysql::server]"] }

On Debian and Ubuntu, this will preseed the mysql-server package with the randomly generated root password in the recipe file. On other platforms, it simply installs the required packages. It will also create an SQL file, /etc/mysql/grants.sql, that will be used to set up grants for the root, repl and debian-sys-maint users.

The recipe will perform a node.save unless it is run under chef-solo after the password attributes are used to ensure that in the event of a failed run, the saved attributes would be used.

Chef Solo Note: These node attributes are stored on the Chef server when using chef-client. Because chef-solo does not connect to a server or save the node object at all, to have the same passwords persist across chef-solo runs, you must specify them in the json_attribs file used. For example:

{
  "mysql": {
    "server_root_password": "iloverandompasswordsbutthiswilldo",
    "server_repl_password": "iloverandompasswordsbutthiswilldo",
    "server_debian_password": "iloverandompasswordsbutthiswilldo"
  },
  "run_list":["recipe[mysql::server]"]
}

On EC2 nodes, use the server_ec2 recipe and the mysql data dir will be set up in the ephmeral storage.

{ "run_list": ["recipe[mysql::server_ec2]"] }

When the ec2_path doesn't exist we look for a mounted filesystem (eg, EBS) and move the data_dir there.

The client recipe is already included by server and 'default' recipes.
