Mac OSXにhomebrewでmysqlをインストール

どうもrootのパスワードが設定できなくて、2回ぐらいuninstallしましたが、
テーブル定義？(/usr/local/var/mysql/)がのこっていたので、うまくいかず、
まっさらな状態にするとインストールできました

$ brew uninstall mysql
$ rm -r /usr/local/var/mysql

インストール
$ brew install mysql

==> Downloading http://mysql.mirrors.pair.com/Downloads/MySQL-5.1/mysql-5.1.54.tar.gz
[省略]
==> Caveats
Set up databases with:
unset TMPDIR
mysql_install_db

If this is your first install, automatically load on login with:
cp /usr/local/Cellar/mysql/5.1.54/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/5.1.54/com.mysql.mysqld.plist ~/Library/LaunchAgents
launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

Note on upgrading:
We overwrite any existing com.mysql.mysqld.plist in ~/Library/LaunchAgents
if we are upgrading because previous versions of this brew created the
plist with a version specific program argument.

Or start manually with:
mysql.server start
==> Summary
/usr/local/Cellar/mysql/5.1.54: 220 files, 45M, built in 8.2 minutes

ひとまずインストール完了

上記のコマンドをそのままやっても良いが、
自動的に起動してほしくないので、
セットアップのみ実行

$ mysql_install_db
$ mysql.server start
$ /usr/local/Cellar/mysql/5.1.54/bin/mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

[ルートのパスワード設定しますか？]
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

[ルート以外のユーザは削除する？]
Remove anonymous users? [Y/n] n
... skipping.

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

[リモートからルートのログインする？]
Disallow root login remotely? [Y/n] Y
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

[テスト用のデータベースは削除する？]
Remove test database and access to it? [Y/n] n
... skipping.

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

[今すぐ設定を反映させる？]
Reload privilege tables now? [Y/n] Y
... Success!

Cleaning up...



All done! If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!
