MongoDBでらくしようと思い立ちました。
インストール
takuya@air:~$ brew install mongodb

==> Caveats
If this is your first install, automatically load on login with:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/Cellar/mongodb/2.0.2-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
If this is an upgrade and you already have the org.mongodb.mongod.plist loaded:
launchctl unload -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
cp /usr/local/Cellar/mongodb/2.0.2-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist
Or start it manually:
mongod run --config /usr/local/Cellar/mongodb/2.0.2-x86_64/mongod.conf
MongoDB 1.8+ includes a feature for Write Ahead Logging (Journaling), which has been enabled by default.
To disable journaling, use --nojournal.

各ファイルについて
testはコレクション
db.users.save( { name:"takuya"} )
これは次の意味になります。
・データベースに
・user コレクションを作って
・name というキーを持つドキュメントを保存
使い方基本
db.users.save({name: 'moro', tags: ['ruby', 'rails'], login_count: {today: 5, total: 25}}) #↑db.users.save( <JSON> ) db.users.find() # ↑ find 関数 サンプル > db.users.save( { name:"takuya"} ) > db.users.find() { "_id" : ObjectId("508cb3c882c00c9e84281020"), "name" : "takuya" } > bye
TIPS
mongoシェルはSpiderMonkeyシェルの拡張
