MongoDB and Python

Running MongoDB

On some platforms—such as Ubuntu—the package manager will automatically start the mongod daemon for you, and ensure it starts on boot also. On others, such as Mac OS X, you must write your own script to start it, and manually integrate with launchd so that it starts on system boot.

Note that before you can start MongoDB, its data and log directories must exist.

If you wish to have MongoDB start automatically on boot on Windows, 10gen have a document describing how to set this up at http://www.mongodb.org/display/DOCS/Windows+Service

To have MongoDB start automatically on boot under Mac OS X, first you will need a plist file. Save the following (changing db and log paths appropriately) to /Library/LaunchDaemons/org.mongodb.mongod.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>RunAtLoad</key>
        <true/>
        <key>Label</key>
        <string>org.mongo.mongod</string>
        <key>ProgramArguments</key>
        <array>
                <string>/usr/local/mongodb/bin/mongod</string>
                <string>--dbpath</string>
                <string>/usr/local/mongodb/data/</string>
                <string>--logpath</string>
                <string>/usr/local/mongodb/log/mongodb.log</string>
        </array>
</dict>
</plist>

Next run the following commands to activate the startup script with launchd:

sudo launchctl load /Library/LaunchDaemons/org.mongodb.mongod.plist
sudo launchctl start org.mongodb.mongod
