本篇內(nèi)容主要講解“在MAC下配置MySQL數(shù)據(jù)庫出現(xiàn)亂碼怎么解決”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實(shí)用性強(qiáng)。下面就讓小編來帶大家學(xué)習(xí)“在MAC下配置mysql數(shù)據(jù)庫出現(xiàn)亂碼怎么解決”吧!

最近安裝了mac osx lion系統(tǒng)，然后安裝了mysql5.5.16版本的進(jìn)行開發(fā)，但是大家都知道，的默認(rèn)編碼是latin1，如果存儲(chǔ)中文的話就會(huì)出現(xiàn)亂碼，然后就狂google這個(gè)問題，但是一直都沒有解決，網(wǎng)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(gè)*.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(dòng)mysql服務(wù)器就可以。
可是我試過好多次，這樣修改之后，mysql服務(wù)根本就啟動(dòng)不了。
偶然的機(jī)會(huì)，我發(fā)現(xiàn)了一個(gè)關(guān)于在linux下配置mysql的編碼問題的方法，抱著試試看的態(tài)度，我進(jìn)行了修改，發(fā)現(xiàn)真的可以用，因此發(fā)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(gè)*.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(gè)配置我沒有試過，不知道能不能成功），關(guān)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(dòng)mysql服務(wù)器就可以。
然后再就入mysql數(shù)據(jù)庫查看編碼發(fā)現(xiàn)改成了utf8了。
下面是我重啟mysql服務(wù)器進(jìn)入mysql數(shù)據(jù)庫查出來的結(jié)果：

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

# 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.
