MongoDB data/db not found

Question

I do gave this path for data/db

/usr/local/Cellar/mongodb/3.2.6/data/db

The following step was made in order to create a bound to mongodb folder

sudo mongod --directoryperdb --dbpath /usr/local/Cellar/mongodb/3.2.6/data/db --logpath /usr/local/Cellar/mongodb/3.2.6/log/mongodb.log --logappend -rest

When initialize sudo mongod in terminal the following error appears:

2016-06-08T14:45:06.970+0200 I CONTROL  [initandlisten] MongoDB starting : pid=8107 port=27017 dbpath=/data/db 64-bit host=iMac-Krystyna-2.local

Can you please explain what is wrong and maybe show some common practice in order to work correctly with MongoDB?

Answer 1

You need to create this directory as root

Either you need to use sudo , e.g. sudo mkdir -p /data/db

Or you need to do su - to become superuser, and then create the directory with mkdir -p /data/db
