Location of the mongodb database on mac

问题

I am kind of new to mac as well as mongodb.

I have a weird doubt, accessing the database created using mongodb on mac?

I know, in windows there is a folder called c:\data\db, where my database files are stored.

How and where in mac, the database is stored.

I remember doing something like

sudo mkdir -p /data/db
sudo chown `id -u` /data/db

to create such a folder on mac, but I didn't find any database file in this folder, though i created a database.

Where are the database files saved on mac?

Any help would be really appreciated.

回答1:

The default data directory for MongoDB is /data/db.

This can be overridden by a dbpath option specified on the command line or in a configuration file.

If you install MongoDB via a package manager such as Homebrew or MacPorts these installs typically create a default data directory other than /data/db and set the dbpath in a configuration file.

If a dbpath was provided to mongod on startup you can check the value in the mongo shell:

db.serverCmdLineOpts()

You would see a value like:

"parsed" : {
    "dbpath" : "/usr/local/data"
},

If mongodb is installed via Homebrew the default location is:

/usr/local/var/mongodb

See the answer from @simonbogarde for the location of other interesting files that are different when using Homebrew.

Thanks @Mark, I keep forgetting this again and again. After installing MongoDB with Homebrew:

• The databases are stored in the /usr/local/var/mongodb/ directory
• The mongod.conf file is here: /usr/local/etc/mongod.conf
• The mongo logs can be found at /usr/local/var/log/mongodb/
• The mongo binaries are here: /usr/local/Cellar/mongodb/[version]/bin

I had the same problem, with version 3.4.2

to run it (if you installed it with homebrew) run the process like this:

$ mongod --dbpath /usr/local/var/mongodb

回答5:

I have just installed mongodb 3.4 with homebrew.(brew install mongodb) It looks for /data/db by default.

回答6:

Env: macOS Mojave 10.14.4

Install: homebrew

Location:/usr/local/Cellar/mongodb/4.0.3_1

Note :If update version by brew upgrade mongo,the folder 4.0.4_1 will be removed and replace with the new version folder
