MongoDBをインストールするなど。

Macならbrewコマンドでインストール出来るもんなのね〜。

$ brew install mongodb
Warning: No developer tools installed.
You should install the Command Line Tools.
Run `xcode-select --install` to install them.

==> Caveats
To have launchd start mongodb at login:
    ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
    launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
    mongod

そうしたら、こんなエラーが出てもうた、、、

$ mongo
MongoDB shell version: 2.4.8
connecting to: test
Tue Nov  5 21:04:14.625 Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145
exception: connect failed

で、この辺を見てみた。

$ mongod --repair
$ sudo mongod

そしたら、なんか使えるようになったっぽいが、warningが、、、（汗）

$ mongo
MongoDB shell version: 2.4.8
connecting to: test
Server has startup warnings:

こういう時、英語で探すとたくさんhelpが出てくるとこまではいいけど、どこまで信じていいものやら。。
何か分かったら、次回（あるのか？）書きます。
