mysqld cookbook
Manage your mysqld servers with this cookbook.
Unlike the official opscode mysql cookbook,
it doesn't mess with the default mysql configuration. If you do not specify anything explicitly, the
defaults of your distribution will be used.
(At least if I do not mess up - Check the
default attributes,
if unsure (and file a pull request if you need to correct anything))
Features
- Defaults to OS settings unless explicitly specified otherwise
- Supports all my.cnf settings
Currently tested on Ubuntu 16.04, it should work on other Ubuntu/ Debian systems as well, as long as a compatible database version is used (e.g. mysql-5.7
or mariadb-10.1
).
Other versions might require adaption of some my.cnf
attributes.
Note: The support for RHEL was dropped with version v2.2.0
, pull-requests are welcome!
Contributions to support other systems are very
welcome!
Requirements
You need to add the following line to your metadata.rb
depends 'mysqld'
Attributes
Configuration
Everything in your my.cnf can be maintained using attributes.
Consider using the provides LWRPs (see below)
If you do not specify anything, the defaults of your os will be used.
This recipe supports every setting in the my.cnf. All your settings will be merged with the
systems default, and then written to the my.cnf config file. The packages to install, the path to
my.cnf as well as the name of the service are set automatically, and can be overwritten using the
following attributes:
node['mysqld']['my.cnf_path'] node['mysqld']['service_name'] node['mysqld']['mysql_packages'] # When node['mysqld']['use_mariadb'] == false node['mysqld']['mariadb_packages'] node['mysqld']['mariadb_galera_packages'] # When using mariadb_galera_install recipe
The configuration is stored in the node['mysqld']['my.cnf']
hash, and can be adapted like so
# node['mysqld']['my.conf'][<category>][<key>] = <value> node['mysqld']['my.cnf']['mysqld']['bind-address'] = '0.0.0.0'
This will expand to the following in your config file (leaving all other settings untouched)
[mysqld]
bind-address = 0.0.0.0
To remove a default option, you can pass false
or nil
as the value
# Remove deprecated innodb option default['mysqld']['my.cnf']['mysqld']['innodb_additional_mem_pool_size'] = false
As the configuration file is constructed from the config hash, every my.cnf configuration option is
supported.
node['mysqld']['root_password'] = 'yourpass'
Recipes
default
- Setup official MariaDB repository
- Install MariaDB server
- Configure MariaDB server according to the attributes. If no attributes are given, stick with the systems default
mariadb_repository
Sets up official MariaDB repository to install packages from.
Configure it using the following attributes
node['mysqld']['repository']['version'] # Defaults to '10.1' node['mysqld']['repository']['mirror'] # Defaults to HostEurope mirror
install
Install mariadb/ mysql packages (according to attributes, defaults to mariadb-server
)
configure
Configure mysql according to attributes. Sets the databases root account (resp. debian-sys-maint on
Debian/Ubuntu systems) to use the password in node['mysqld']['root_password']
, if the attribute is
set.
mariadb_galera_init
Run mariadb_repository
and mariadb_galera_install
recipes, then configure as the configure
recipe would do, but start mariadb with --wsrep-new-cluster --wsrep_cluster_address=gcomm://
to
initialize a new Galera cluster.
Use this if you want to setup a new Galera cluster, and run it on your first node once:
$ sudo chef-client --once -o 'recipe[mysqld::mariadb_galera_init]'
Once you connected the other nodes using the regular recipes, re-run chef-client as you did on the
other servers.
Note: If you use a wrapper cookbook to configure your instances, attributes might not be available
when running the recipe with -o recipe[]
. Create a mariadb_galera_init recipe in your wrapper
cookbook, calling this recipe if you have trouble.
Providers
mysqld
You can configure your database also using the mysqld
provider:
include_recipe 'mysqld::mariadb_galera_install' # Name attribute will be ignored. Choose something that makes sense for you mysqld 'galera' do my_cnf { 'bind-address' => '0.0.0.0' } end
password
You can set passwords (incl. root and debian-sys-maint accounts) using this provider.
By default, the provider uses the created root/debian-sys-maint accounts depending on the system you
are on.
mysqld_password 'root' do password 'get_from_data_bag_maybe?' # If required, you can specify your own auth-scheme here # auth '-u specialuser -pmypass' end
