MongoDB Storage Engine

Question

How can I change the storage engine of MongoDB permanently so that I don't have to run mongod without having to specify the storage engine every time? I am using shell version 3.2.7 on Windows 7 32-bit. I got an error that said:

28663 Cannot start server. The default storage engine 'wiredTiger' is not available with this build of mongod. Please specify a different storage engine explicitly, e.g. --storageEngine=mmapv1., terminating.

Also does anyone know how to cleanly shutdown the server when I am done working? I use Ctrl+C but it causes an error, then I have to empty the data folder to get the process to start again.

Answer 1

You can set that in the storage.config setting within your YAML configuration file.

Example:

storage:
  dbPath: d:\data\db
  engine: mmapv1

If you're not already starting your MongoDB service using a configuration file, see here for the details on how do to that for Windows.
