Install MongoDB On Mac Os

Question

I Install MongoDB on Mac-os version 10.11.4. when I run mkdir -p/data/db in terminal. It show notice: mkdir: /data/db: Permission denied. Please help me. What should I do? Thank.

Answer 1

mkdir -p/data/db is trying to create a directory at the root of your file system. MongoDB will try to create files in /data/db by default. You dont have the rights to create directories in this location. You have two options:

Either 1. run the same command as sudo:

sudo mkdir -p /data/db

Or 2. when you start the mongod process use the --dbpath option to tell it to create its files in another location. For example:

mongod --dbpath ~/db
