MySQL 5.6.8でmy.cnfのサンプルがなくなった

FreeBSD 10.1-RELEASEにMySQL 5.6.22をインストールしたら、おなじみのmy-medium.cnfが無くなっていた。my-default.cnfというものはあるが、中身を見るとどう見ても空っぽ。

公式サイトによれば、5.6.8から従来のcnfファイルの提供は中止され、mysql_install_dbコマンドで生成するようになったらしい。てなわけで実行してみる。

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:
 
  /usr/local/bin/mysqladmin -u root password 'new-password'
  /usr/local/bin/mysqladmin -u root -h MY.HOSTNAME password 'new-password'
 
Alternatively you can run:
 
  /usr/local/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 . ; /usr/local/bin/mysqld_safe &
 
You can test the MySQL daemon with mysql-test-run.pl
 
  cd mysql-test ; perl mysql-test-run.pl

New default config file was created as /usr/local/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

/usr/local/my.cnfが出来たようだ。中身はというと…

/usr/local/my.cnf

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

これはひどい。どう見ても/usr/local/share/mysql/my-default.cnfをコピーしただけです。本当にありがとうございました。

スクリプトにbasedirとdatadirを渡してるんだから、せめて反映したcnfくらい作ってくれてもいいんじゃないかなぁ…。自分みたいなMySQLの子細は分からないけど、とりあえず使ってみたいユーザーにとっては非常に厳しい。

さて、どうしたものか。
