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, should work on RHEL and Debian as well. Contributions to support other systems are very welcome!
You need to add the following line to your metadata.rb
depends 'mysqld'
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 using mysql_install recipe
node['mysqld']['mariadb_packages'] # When using mariadb_install recipe
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'
- Setup official MariaDB repository
- Install MariaDB server
- Configure MariaDB server according to the attributes. If no attributes are given, stick with the systems default
Runs mariadb_apt_repository
or mariadb_yum_repository
recipe according to your platform
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
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 mariadb packages (according to attributes, defaults to mariadb-server
)
Install mysql packages (according to attributes, defaults to mysql-server
)
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.
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.
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
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
