Components

mongod

mongod is the primary daemon process for the MongoDB system. It handles data requests, manages data format, and performs background management operations.

--dbpath <path> Specify a directory for the mongod instance to store its data. Typical locations include: /srv/mongodb, /var/lib/mongodb or /opt/mongodb

Unless specified, mongod will look for data files in the default /data/db directory. (Windows systems use the \data\db direc‐ tory.) If you installed using a package management system. Check the /etc/mongodb.conf file provided by your packages to see the configuration of the dbpath.

--directoryperdb Alters the storage pattern of the data directory to store each database's files in a distinct folder. This option will create directories within the --dbpath named for each directory.

Use this option in conjunction with your file system and device configuration so that MongoDB will store data on a number of distinct disk devices to increase write throughput or disk capacity.
