Specify a Data Directory in mongodb

Specify a Data Directory

If you want mongod to store data files at a path other than /data/db you can specify a dbPath. The dbPath must exist before you start mongod. If it does not exist, create the directory and the permissions so that mongod can read and write data to this path. For more information on permissions, see the security operations documentation.

To specify a dbPath for mongod to use as a data directory, use the --dbpath option. The following invocation will start a mongod instance and store data in the /srv/mongodb path

mongod --dbpath /srv/mongodb/
