Mongod -- config/usr/local/etc/mongod. conf cannot be started

Problem description: {code...} input mongod print: {code...} environment: osx (mac) Problem description:

Run the command mongod -- config/usr/local/etc/mongod. conf to start mongodb without printing any information. I used it all well before. Why?

Input mongod to print:

The error messages clearly indicate/data/dbDoes not exist. Check this point first.

T15: 05: 42.633 + 0800 I STORAGE [initandlisten] exception in initAndListen: 29 Data directory/data/db not found., terminating

Create this directory and try again if necessary

sudo mkdir /data/db
