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](http://community.opscode.com/cookbooks/homebrew) on Mac OS X. Resources and Providers ======================= The LWRP that used to ship as part of this cookbook has been refactored into the [database](http://community.opscode.com/cookbooks/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. 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. For more infromation on the compile vs execution phase of a Chef run: * http://wiki.opscode.com/display/chef/Anatomy+of+a+Chef+Run 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]"] } License and Author ================== - Author:: Joshua Timberman () - Author:: AJ Christensen () - Author:: Seth Chisamore () - Author:: Brian Bianco () - Author:: Jesse Howarth () - Author:: Andrew Crump () Copyright:: 2009-2012 Opscode, Inc Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
