MongoDB configuration backends

MongoDB is a NoSQL database that can be used both for storing configuration and sessions. You need to install Perl MongoDB module to be able to use this backend.

See how to change configuration backend to change your configuration database.

Configuration

To use a MongoDB backend, configure your lemonldap-ng.ini file (section configuration) :

  • Choose MongoDB as type
  • Set dbName and collectionName parameters if different than default values (llConfDB and configuration)
  • Set host and if needed db_name username, password and ssl fields as follow.

Example :

[configuration]
type = MongoDB
dbName = llConfDB
collectionName = configuration
host = 127.0.0.1:27017
ssl = 1
; authentication parameters
db_name = admin
user = lluser
password = llpassword
Optional parameters (see MongoDB::MongoClient man page)
Name Comment Example
db_name Admin database (default: admin) admin
auth_mechanism Authentication mechanism PLAIN
auth_mechanism_properties
connect_timeout Connection timeout 10000
ssl Boolean or hash ref (default: 0) 1
username Username to use to connect lluser

Mini MongoDB howto

Just some commands needed to create collection and user:

> db.createCollection("configuration")
...
> db.createUser({user:"lluser",pwd:"llpassword",roles:["readWrite"]})
...
> exit
