This cookbook includes recipes and provider to install and configure postgresql database. This cookbook was tested with Postgresql 9.1 and 9.2, and should work with 9.0 too.
- This cookbook version (0.1.1) tested only on Debian squeeze.
- You must have repository with Postgres version 9.x
This cookbook have server and client attribute files.
With client attributes(["postgresql"]["client"]) you can set only postgresql client and library version.
Server attributes are starting from ["postgresql"]["defaults"] and used as default attributes for postgresql provider. You should not override this defaults, you can pass your settings to provider instead.
- :create: creates postgresql cluster
- cluster_name: name attribute. Cluster name (e.g. main).
- cookbook: cookbook for templates. Skip this for default templates.
- databag: data bag for users and databases, if you don't want create users or databases with chef you can skip this.
- cluster_create_options: options for pg_createcluster (only locale related options)
- configuration: Hash with configuration options for postgresql. Configuration divided to sections, see examples.
- hba_configuration: Array with hba configuration, see examples.
- ident_configuration: Array with ident configuration, see examples.
- replication: Hash with replication configuration. Now provider support only streaming replication. See examples. Cluster must be copied before chef run.
Example master database setup:
postgresql "main" do
cluster_create_options [ "locale" => "ru_RU.UTF-8" ]
configuration(
:version => "9.1",
:connection => {
:listen_addresses => "'192.168.0.1'",
:max_connections => 300,
:ssl_renegotiation_limit => 0
},
:resources => {
:shared_buffers => "512MB",
:maintenance_work_mem => "64MB",
:work_mem => "8MB",
},
:queries => {
:effective_cache_size => "512MB"
},
:wal => { :checkpoint_completion_target => "0.9" },
:logging => { :log_min_duration_statement => "200" }
)
hba_configuration(
[ { :type => "host", :database => "all", :user => "all", :address => "192.168.0.0/24", :method => "md5" },
{ :type => "host", :database => "replication", :user => "postgres", :address => "192.168.0.10/32", :method => "trust" } ]
)
end
Example slave database setup:
postgresql "main" do
cluster_create_options [ "locale" => "ru_RU.UTF-8" ]
configuration(
:version => "9.1",
:connection => {
:listen_addresses => "'192.168.0.10'",
:max_connections => 300,
:ssl_renegotiation_limit => 0
},
:resources => {
:shared_buffers => "512MB",
:maintenance_work_mem => "64MB",
:work_mem => "8MB",
},
:queries => {
:effective_cache_size => "512MB"
},
:wal => { :checkpoint_completion_target => "0.9" },
:logging => { :log_min_duration_statement => "200" }
:standby => { :hot_standby => "on" }
)
hba_configuration(
[ { :type => "host", :database => "all", :user => "all", :address => "192.168.0.0/24", :method => "md5" },
{ :type => "host", :database => "replication", :user => "postgres", :address => "192.168.0.10/32", :method => "trust" } ]
)
replication( :standby_mode =>"on", :primary_conninfo => "host=192.168.0.1", :trigger_file => "/tmp/pgtrigger" )
end
- More examples
- Better replication support
- Provider for database declaration
