I'm using ubuntu 16.04! Is it possible to change the data directory for a specific database in mongo? I'm trying to setup this recommendation engine and I was asked to create a new MongoDB database and set its path to folder.
Pre-version 3.0.0, all the databases that one
mongod hosts have to be in the same dbpath folder which can be set via command arguments using the
--dbpath flag or the config file.
You could however run multiple mongods and host them individually? either on different ip/ports.
Version 3.0.0 you can use the
--directoryperdb flag within the command arguments or config to set multiple directories per database (See https://docs.mongodb.com/manual/reference/program/mongod/#cmdoption--directoryperdb)
Uses a separate directory to store data for each database. The directories are under the --dbpath directory, and each subdirectory name corresponds to the database name.
When you start mongod.exe you can set the database path with the
mongod.exe --dbpath "path to your folder"
