Initial Setup

The database is stored on a dedicated partition (on the SSD RAID); to prepare and mount the filesystem:

  mkfs.ext4 /dev/ssdvg/mongo
  mount /var/lib/mongo

To install the WiredTiger version of the database, enable the MongoDB community edition. Install the server, client, and libraries:

  yum -y install mongodb-org

In /etc/mongod.conf, enable incoming connections from the ABEL-internal network address of the portal node (e.g. for at.local) and require authentication:


  authorization: enabled

Activate the service by default (i.e. at boot(7) time) and start the database:

  chkconfig mongod on
  /etc/init.d/mongod start

Finally, create a database user laportal with administrator rights:

  mongo --authenticationDatabase admin

  use admin
  db.createUser( { user: "laportal", pwd: "????????", roles: [ "userAdminAnyDatabase" ] } )

Starting, Stopping, and Restarting the Database Server

  sudo /etc/init.d/mongod start|stop|restart

LAP Store Configuration

For the time being, at least, we assume that all annotations (by all LAP users) share one database and one database user; to initially create the database and user:

  mongo --verbose -u laportal -p '????????' admin

  use lapstore
  db.createUser({ user: "lapstore", pwd: "????????", roles: [ "readWrite" ] })

Interactive Database Inspection and Manipulation

To connect to the LAP Store using the MongoDB Shell:

  mongo --verbose -u lapstore -p '????????' lapstore

To inspect the contents of a specific collection (use show collections or db.getCollectionNames() for the selection):


To drop all collections, i.e. free up storage space; this will render all Galaxy files in all user histories (i.e. receipts, referring to collections) useless, thus must only be used on development instances:

  db.getCollectionNames().forEach(function(foo) { if (foo.indexOf("system.") == -1) db[foo].drop(); })

Rotating Log Files

It appears that the community edition (in version 3.0 and upwards) does not rotate log files itself; look into how to regularly issue the logRotate command or send a USR1 signal.
