mac の開発環境構築 〜MySQL〜

方針

続いてデータベース、MySQLをインストールします。

バージョンの確認

まずはデフォルトのMySQLの確認。

$ mysql -v
-bash: mysql: command not found
$ ps ax | grep mysql

あれ?デフォルトでMySQLは入ってなかったかな??

portsの確認

ではMacPortsでインストールできるMySQLバージョンの確認。

$ port search mysql
・・・
mysql4 @4.1.22 (databases)
    Multithreaded SQL database server

mysql5 @5.1.51 (databases)
    Multithreaded SQL database server

mysql5-devel @5.5.2-m2 (databases)
    Multithreaded SQL database server

mysql5-server @5.1.51 (databases)
    Multithreaded SQL database server

mysql5-server-devel @5.5.2-m2 (databases)
    Multithreaded SQL database server
・・・

インストール時に指定できる variants を確認

$ port variants mysql5-server
mysql5-server has no variants

mysqlインストール

mysql5-serverをインストールします。

$ sudo port install mysql5-server
・・・

mysql5-serverをloadしてください。とのこと。

mysql5-serverをload

言われるままに、mysql5-serverをloadしてみます。

$ sudo port load mysql5-server

データベースのセットアップ?

お次も言われるまま

$ sudo -u _mysql mysql_install_db5
Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql5/bin/mysqladmin -u root -h macmini.local password 'new-password'

Alternatively you can run:
/opt/local/lib/mysql5/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /opt/local ; /opt/local/lib/mysql5/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /opt/local/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /opt/local/lib/mysql5/bin/mysqlbug script!

パスワードを設定してください。とのことです。

パスワードを設定

$ sudo /opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql5/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/opt/local/var/run/mysql5/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/opt/local/var/run/mysql5/mysqld.sock' exists!

おっと?connectがつながらないですって!

mysqlを起動

とりあえず起動してみることに

$ sudo /opt/local/share/mysql5/mysql/mysql.server start
Password:
Starting MySQL
. SUCCESS! 

再度、パスワードを設定

もいちどトライ

$ sudo /opt/local/lib/mysql5/bin/mysqladmin -u root password 'new-password'

今度はうまく通ったみたい。

mysqlにログイン

ログインしてみる

$ /opt/local/lib/mysql5/bin/mysql -u root -p
Enter password:
