Install MongoDB on OS X (10.6 Snow Leopard)

Here are the steps:

1. Download the pre-compiled binaries from:
   http://www.mongodb.org/display/DOCS/Downloads
   

2. Create mongodb folder and unpack the files there
   sudo mkdir /usr/local/mongodb

3. Create the configuration file
   sudo touch /usr/local/mongodb/mongod.conf
   and paste these lines in it:
   dbpath = /usr/local/mongodb
logpath = /var/logs/mongodb/output.log
bind_ip = 127.0.0.1
# DEFAULTS
# port = 27017
# noauth = true


   More configurations options you can find here:
   http://www.mongodb.org/display/DOCS/Command+Line+Parameters

4. Add “/usr/local/mongodb/bin” to your $PATH
   or
   only for Leopard versions create a file “/etc/paths.d/mongodb” where you paste this path.

5. Make mongodb starts when system starts
   touch /Library/LaunchDaemons/org.mongodb.mongod.plist
   and paste these lines in it:<?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>org.mongodb.mongod</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/mongodb/bin/mongod</string>
<string>run</string>
<string>--config</string>
<string>/usr/local/mongodb/mongod.conf</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/output.log</string>
<key>StandardOutPath</key>
<string>/var/log/mongodb/output.log</string>
</dict>
</plist>


   and then
   sudo launchctl load /Library/LaunchDaemons/org.mongodb.mongod.plist


6. See if it works (type in a terminal):
   
$> mongo
=> MongoDB shell version: 1.2.4
url: test
connecting to: test


That’s it.
