在MAC下配置mysql数据库出现乱码怎么解决
本篇内容主要讲解"在MAC下配置mysql数据库出现乱码怎么解决"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"在MAC下配置mysql数据库出现乱码怎么解决"吧!
最近安装了mac osx lion系统，然后安装了mysql5.5.16版本的进行开发，但是大家都知道，的默认编码是latin1，如果存储中文的话就会出现乱码，然后就狂google这个问题，但是一直都没有解决，网上大部分的回答都是如下：
1.拷贝/usr/local/mysql/support-files下的任意一个*.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.重新启动mysql服务器就可以。
可是我试过好多次，这样修改之后，mysql服务根本就启动不了。
偶然的机会，我发现了一个关于在linux下配置mysql的编码问题的方法，抱着试试看的态度，我进行了修改，发现真的可以用，因此发这篇博文希望装mac的朋友不用再走弯路了。配置方法如下：
1.拷贝/usr/local/mysql/support-files下的任意一个*.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]，这个配置我没有试过，不知道能不能成功），关键在这里的配置，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.重新启动mysql服务器就可以。
然后再就入mysql数据库查看编码发现改成了utf8了。
下面是我重启mysql服务器进入mysql数据库查出来的结果：
Java代码

至此，这个困扰多日的问题终于解决了。
附修改好的my.cnf文件内容，不知道为什么附件我上传不了，就把代码贴出来吧：

# Example MySQL config file for small systems.
#
# 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:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.
