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?

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

On Mac OS Big Sur, the command `sudo mkdir -p /data/db` produces the error: `mkdir: /data/db: Read-only file system`. – terrymorse Apr 07 '21 at 16:12
should mongodb user have access to `/data/db`? – alper May 24 '22 at 00:24

You can also give this command sudo mongod --dbpath=/var/lib/mongodb. Open another terminal and run your mongod.

I had the same issue. This worked for me:

sudo mongod --dbpath ~/data/db

In my case, an incorrect conf file caused Mongo to use default settings (i.e. using /data/db as the storage path. Because /data/db doesn't exist, it complains.

Possible sources of incorrect config include:

(1) Unquoted strings. E.g. storage.dbPath should be "some/path" (2) Incorrect bindIp. It seems an array of IPs is not supported.

So my fix was simply to use quoted strings in those places: storage: dbPath: "/some/path" net: bindIp: "127.0.0.1"

Note: My "/some/path" has permissions drwxr-xr-x (755) and is owned by mongodb/mongodb. And it works.

MongoDB try to find data/db folder under root directory of your system. try to create folder under /data/db.
