MacにMySQLを導入する (Homebrewを使って)

Posted at

MySQLをインストール

brew install mysql

データベースの初期化

$ unset TMPDIR
$ mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

とりあえず起動と停止

$ mysql.server start
$ mysql.server stop

ルートのパスワード変更

$ mysql.server start
$ mysqladmin -u root password 'new-password'

で、できるはずが、、、

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

なんで?

パスワード変更で Access denied と言われた時の対処

パスワードのリセットをしちゃいます。
safeモードで起動し直し。

$ mysql.server stop
$ mysqld_safe --skip-grant-tables &

で、ログインする。

$ mysql -u root
mysql >

ログインできたらmysqlデータベースのuserテーブルを再構築しちゃう

mysql> use mysql;
mysql> truncate table user;
mysql> flush privileges;
mysql> grant all privileges on *.* to root@localhost identified by 'password' with grant option;
mysql> flush privileges;
mysql> quit;

そしてMySQLを再起動してログイン

$ mysql -u root -p
Enter password: password
mysql >

自動起動設定

$ ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

homebrew.mxcl.mysql.plist を開いてKeepAliveをNOにしておくのもいいよ。

my.cnfの設置
