MongoDB module

This module manages mongodb services. It provides the functions for mongod and mongos instances.

Works for

RHEL/CentOS 6+
Debian 6+
Ubuntu 10.04 and newer

Requirements

You need a class which installes the mongodb repository.
You have to change that in params.pp and install.pp or remove the repo part from install.pp if you have other ways to get the mongodb repo into your server.

For Redhat/CentOS I use the yum module by http://www.example42.com. (and created my own yum::repo::mongodb) The repo for Redhat is http://downloads-distro.mongodb.org/repo/redhat/os/x86_64 .
All information about how to configure the mongodb repo of your OS can be found here:
http://docs.mongodb.org/manual/installation/

Parameters:

Starting mongod

mongod_instance = despription of mongd service (shard1, config, etc) (required)
mongod_bind_ip = listen ip (defaul; emtpy, so listen in all)
mongod_port = listen port (defaul; 27017)
mongod_replSet = Name of ReplSet (optional)
mongod_enable = Enable/Disable service at boot (default: true)
mongod_running = Start/Stop service (default: true)
mongod_configsvr = is config server true/false (default: false)
mongod_shardsvr = is shard server true/false (default: false)
mongod_logappend = Enable/Disable log file appending (default: true)
mongod_rest = Enable/Disable REST api (default: true)
mongod_fork = Enable/Disable fork of mongod process (default: true)
mongod_add_options = Array. Each field is "key" or "key=value" for parameters for config file

Starting mongos (mongo loadbalancer)

mongos_instance = despription of mongd service (shard1, config, etc) (required)
mongos_bind_ip = listen ip (defaul; emtpy, so listen in all)
mongos_port = listen port (defaul; 27017)
mongos_configServers = String with comma seperated list of config servers (optional)
mongos_enable = Enable/Disable service at boot (default: true)
mongos_running = Start/Stop service (default: true)
mongos_logappend = Enable/Disable log file appending (default: true)
mongos_fork = Enable/Disable fork of mongod process (default: true)
mongos_add_options = Array. Each field is "key" or "key=value" for parameters for config file

Sample Usage:

just a mongodb server with replSet

	node mongod.my.domain {
		include mongodb
		mongodb::mongod {
			"my_mongod_instanceX":
				mongod_instance => "mongodb1",
				mongod_replSet => "mongoShard1",
				mongod_add_options => ['fastsync','slowms = 50']
		}
	}

More complex building of mongo sharding cluster

4 nodes (3 of them config server) with 4 shards in replecation

	node mongo_sharding_default {

    	# Install MongoDB
    	include mongodb

    	# Install the MongoDB shard server
    	mongodb::mongod {'mongod_Shard1': mongod_instance => "Shard1", mongod_port => '27019', mongod_replSet => "Shard1", mongod_shardsvr => 'true' }
    	mongodb::mongod {'mongod_Shard2': mongod_instance => "Shard2", mongod_port => '27020', mongod_replSet => "Shard2", mongod_shardsvr => 'true' }
    	mongodb::mongod {'mongod_Shard3': mongod_instance => "Shard3", mongod_port => '27021', mongod_replSet => "Shard3", mongod_shardsvr => 'true' }
    	mongodb::mongod {'mongod_Shard4': mongod_instance => "Shard4", mongod_port => '27022', mongod_replSet => "Shard4", mongod_shardsvr => 'true' }

    	# Install the MongoDB Loadbalancer server
    	mongodb::mongos {
    		"mongos_profile":
    			mongos_instance => "mongoproxy",
    			mongos_port => 27017,
				mongos_configServers => "mongo1.my.domain:27018,mongo2.my.domain:27018,mongo3.my.domain:27018"
    	}
	}

	node "mongo1.my.domain",
		"mongo2.my.domain",
		"mongo3.my.domain" inherits mongo_sharding_default {

		# Install the MongoDB config server
		include mongodb
		mongodb::mongod {
			"mongod_config":
				mongod_instance => "profileConfig",
				mongod_port => '27018',
				mongod_replSet => '',
				mongod_configsvr => 'true'
		}
	}

	node "mongo4.my.domain" inherits mongo_sharding_default { }
