最近安裝了 mac osx lion 系統，然后安裝了 mysql5.5.16 版本的進行開發，但是大家都知道，的默認編碼是 latin1，如果存儲中文的話就會出現亂碼，然后就狂 google 這個問題，但是一直都沒有解決，網上大部分的回答都是如下：
1. 拷貝 /usr/local/mysql/support-files 下的任意一個 *.cnf 文件到 /etc/my.cnf；
2. 在 my.cnf 文件的[mysqld]和[client]后面添加一句 default-character-set=utf8（或者是 default_character_set=utf8）；
3. 保存退出；
4. 重新啟動 mysql 服務器就可以。
可是我試過好多次，這樣修改之后，mysql 服務根本就啟動不了。
偶然的機會，我發現了一個關于在 linux 下配置 mysql 的編碼問題的方法，抱著試試看的態度，我進行了修改，發現真的可以用，因此發這篇博文希望裝 mac 的朋友不用再走彎路了。配置方法如下：
1. 拷貝 /usr/local/mysql/support-files 下的任意一個 *.cnf 文件到 /etc/my.cnf；
2. 在 my.cnf 文件的[client]后面添加一句 default-character-set=utf8（不是 default_character_set=utf8[i][/i]，這個配置我沒有試過，不知道能不能成功），關鍵在這里的配置，在[mysqld]后面添加如下三句：
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci；
3. 保存退出；
4. 重新啟動 mysql 服務器就可以。
然后再就入 mysql 數據庫查看編碼發現改成了 utf8 了。
下面是我重啟 mysql 服務器進入 mysql 數據庫查出來的結果：

至此，這個困擾多日的問題終于解決了。
附修改好的 my.cnf 文件內容，不知道為什么附件我上傳不了，就把代碼貼出來吧：

# This is for a system with little memory (= 64M) where MySQL is only used
# from time to time and it s important that the mysqld daemon
# doesn t use much resources.

# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:

# In this file, you can use all long options that a program supports.
