MongoDB Configuration inside LabCORES

LabCORES has a MongoDB service running locally on our project server / experiments workstation, Motumbo. The linux daemon is installed by the following structure: Install MongoDB Community Edition on Ubuntu.

The Version

The version is 3.4.9 and supports WiredTiger Storage Engines

The Start

MongoDB must be started within the terminal, with the root user, forcing the instance to use parameters to change default paths of storage and logs. This is a internal initiative to prevent disk running out of space and to organize better the data.

/usr/bin/mongod --dbpath /data/mongodb --logpath /data/mongodb-log/mongod.log &

This is for initial configuration, we are going for a better start process in the future.

The process is running with 2 parameters: dbpath and logpath. Dbpath sets the new folder for the storage files, databases and collections, and logpath sets the directory for daemon process reports. The structure of files are inside the /data folder:

1. dbpath = /data/mongodb
2. logpath = /data/mongodb-log/mongod.log

Databases

The pattern of the names are db_firstName_lastName. The older and not yet described by an owner, or not identified, are named: db_legacy_originalName.
