A guide to show you how to install MongoDB on Mac OS X.

MongoDB 2.2.3

Mac OS X 10.8.2

1. Download MongoDB

Download MongoDB from official website.  Create a mongodb folder as described below

$ cd ~/Download $ tar xzf mongodb-osx-x86_64-2.2.3.tgz $ sudo mv mongodb-osx-x86_64-2.2.3 /usr/local/mongodb

2. MongoDB Data

By default, MongoDB write/store data into the /data/db folder, you need to create this folder manually and assign proper permission.

$ sudo mkdir -p /data/db $ whoami asurendran $ sudo chown asurendran /data/db

3. Add mongodb/bin to $PATH

Create a ~/.bash_profile file and assign /usr/local/mongodb/bin to $PATH environment variable, so that you can access Mongo’s commands easily.

$ cd ~ $ pwd /Users/asurendran $ touch .bash_profile $ vim .bash_profile   export MONGO_PATH=/usr/local/mongodb export PATH=$PATH:$MONGO_PATH/bin   ##restart terminal   $ mongo -version MongoDB shell version: 2.2.3

4. Start MongoDB

Start MongoDB with mongod and make a simple mongo connection with mongo.

Terminal 1

$ mongod MongoDB starting : pid=34022 port=27017 dbpath=/data/db/ 64-bit host=mkyong.local //... waiting for connections on port 27017

Terminal 2

$ mongo MongoDB shell version: 2.2.3 connecting to: test > show dbs local (empty)

Note If you don’t like the default /data/db folder, just specify an alternate path with --dbpath

$ mongod --dbpath /any-directory

5. Auto Start MongoDB (this is optional, I start MongoDB manually)

To auto start mongoDB, create a launchd job on Mac.

$ sudo vim /Library/LaunchDaemons/mongodb.plist

Puts following content :

/Library/LaunchDaemons/mongodb.plist

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>mongodb</string> <key>ProgramArguments</key> <array> <string>/usr/local/mongodb/bin/mongod</string> </array> <key>RunAtLoad</key> <true/> <key>KeepAlive</key> <true/> <key>WorkingDirectory</key> <string>/usr/local/mongodb</string> <key>StandardErrorPath</key> <string>/var/log/mongodb/error.log</string> <key>StandardOutPath</key> <string>/var/log/mongodb/output.log</string> </dict> </plist>

Load above job.

$ sudo launchctl load /Library/LaunchDaemons/mongodb.plist   $ ps -ef | grep mongo 0 71 1 0 1:50PM ?? 0:22.26 /usr/local/mongodb/bin/mongod 501 542 435 0 2:23PM ttys000 0:00.00 grep mongo
