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.

localhost interface. To connect to a server on a different port or interface,
use the --port and --host options.
