MongoDB is a scalable, high-performance, open source, schema-free, document-oriented database. MongoDB was created by 10gen and they have been kind enough to provide pre-compiled binaries for various platforms including OS X.

Get the Code

Switch to /usr/local/src and download the pre-compiled binaries.

cd /usr/local/src
curl --remote-name


Unpack the binaries into /usr/local.

tar -zxvf mongodb-osx-x86_64-VERSION.tgz -C ..

Create a symbolic link to /usr/local/mongodb.

ln -s mongodb-osx-x86_64-VERSION /usr/local/mongodb


Create a folder that will contain your databases. My databases are located in /usr/local/var/mongodb. You can place your databases wherever you'd like but make sure you update the path when mentioned throughout this article.

mkdir -p /usr/local/var/mongodb

Configuration File

Create a configuration file so you can make changes to your database configuration without messing around with command line arguments.

nano /usr/local/mongodb/mongod.conf

Copy and paste the following text into the aforementioned file.

# Location of MongoDB databases
dbpath = /usr/local/var/mongodb
# Location of log files
logpath = /usr/local/var/log/mongodb.log
# Only accept local connections
bind_ip = localhost
# Enable journaling
journal = true
# Enable REST
rest = true
# Enable smaller default file sizes
# (saves space on development servers)
smallfiles = true


Execute the following lines to update your Bash startup script.

echo 'export PATH=/usr/local/mongodb/bin:$PATH' >> ~/.bash_profile

Load the new shell configurations.

source ~/.bash_profile

Manual Start/Stop

Start the server to test your installation.

sudo mongod --config=/usr/local/mongodb/mongod.conf

To shut down the MongoDB server, press CTRL-C.

Automatically Start the Server at Boot

Create a configuration file for Launchd.

sudo nano /Library/LaunchDaemons/org.mongodb.mongod.plist

Copy and paste the following text into the aforementioned file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">



Register with Launchd and start the server.

sudo launchctl load -w /Library/LaunchDaemons/org.mongodb.mongod.plist

Deregister with Launchd.

sudo launchctl unload -w /Library/LaunchDaemons/org.mongodb.mongod.plist

Verify the Installation
