macbook air に mysql をインストール

MacBook Air に テスト用の mysql を homebrew を使ってインストールしました。
Homebrew は macports より最近人気のある、*NIX系のアプリをインストールするのに便利な フレームワークです。
公式サイト： http://mxcl.github.com/homebrew/

Homebrew のインストールには 公式サイトに記載がありますが、

/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

を実行するだけで 簡単にインストールされます。

Homebrew がインストールされた後は
mysql をインストールしてみます。

$ brew install mysql

requires these m4 macros, you'll need to add this path manually.

==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.
OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.
Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:
    LDFLAGS  -L/usr/local/Cellar/readline/6.2.1/lib
    CPPFLAGS -I/usr/local/Cellar/readline/6.2.1/include

==> Caveats
Set up databases to run AS YOUR USER ACCOUNT with:
    unset TMPDIR
    mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
To set up base tables in another folder, or use a different user to run
mysqld, view the help for mysqld_install_db:
    mysql_install_db --help
and view the MySQL documentation:
  * http://dev.mysql.com/doc/refman/5.5/en/mysql-install-db.html
  * http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html
To run as, for instance, user "mysql", you may need to `sudo`:
    sudo mysql_install_db ...options...
Start mysqld manually with:
    mysql.server start
    Note: if this fails, you probably forgot to run the first two steps up above
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.
To connect:
    mysql -uroot
To launch on startup:
* if this is your first install:
    mkdir -p ~/Library/LaunchAgents
    cp /usr/local/Cellar/mysql/5.5.15/com.mysql.mysqld.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
* if this is an upgrade and you already have the com.mysql.mysqld.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
    cp /usr/local/Cellar/mysql/5.5.15/com.mysql.mysqld.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
You may also need to edit the plist to use the correct "UserName".
Warning: m4 macros were installed to "share/aclocal".
Homebrew does not append "/usr/local/share/aclocal"
to "/usr/share/aclocal/dirlist". If an autoconf script you use
requires these m4 macros, you'll need to add this path manually.

/usr/local/Cellar/mysql/5.5.15: 6276 files, 217M, built in 8.1 minutes

約8分でインストール完了です。
すごく簡単にインストールされました。

今回は 実施しませんが、
起動時に mysql も一緒に起動させるには

mkdir -p ~/Library/LaunchAgents
    cp /usr/local/Cellar/mysql/5.5.15/com.mysql.mysqld.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

と実行します。
