以下的文章主要介绍的是实现MySQL支持中文的实际操作步骤，我们大家都知道系统自带的MySQL数据库默认字符集并不是gbk,所以给数据库推广应用与中文程序的开发过程中带来极大的不便。
在没完没了的GBK和UTF8的转换过程中消耗了我们无数的精力以及系统的资源.经过摸索尝试解决了中文MySQL支持问题,经验与大家分享一下.
先将让slack支持中文,方法可以看"linuxsir.org 之Slackware讨论区",然后重新编译MySQL(和PHP搭配之最佳组合),原来系统MySQL(和PHP搭配之最佳组合)的要先用卸载.
login:root
shell> removepkg MySQL(和PHP搭配之最佳组合)
shell> groupadd MySQL(和PHP搭配之最佳组合)
shell> cd /app
shell> mkdir MySQL(和PHP搭配之最佳组合)
shell> chmod 744 MySQL(和PHP搭配之最佳组合)
shell> useradd -G MySQL(和PHP搭配之最佳组合) -s /bin/bash –p /app/MySQL(和PHP搭配之最佳组合) MySQL(和PHP搭配之最佳组合)
shell> chown -R MySQL(和PHP搭配之最佳组合).MySQL(和PHP搭配之最佳组合) MySQL(和PHP搭配之最佳组合)

mcpu 根据CPU类型优化编译，可以让你的mysq表现更好！可选项目很多：i386, i486, i586, i686, pentium, pentium-mmx, pentiumpro, pentium2, pentium3, pentium4, k6, k6-2, k6-3,

错误时候

再回上一步

看见characterset全是gbk就算成功了.
在UTF8字符集的老数据库中,创建中文MySQL支持表脚本如下,对字段加上字符集说明
<ol class="dp-xml"> <li class="alt"><span><span>CREATE TABLE `test`.`cn` ( </span></span></li> <li><span>`zh` CHAR(10) CHARACTER SET gb2312 COLLATE gb2312_chinese_ci NOT NULL, </span></li> <li class="alt"><span>`中文` INT(11) NOT NULL </span></li> <li><span>) </span></li> <li class="alt"> <span class="attribute">ENGINE</span><span> = </span><span class="attribute-value">MYISAM</span><span>; </span> </li> </ol>
注:CHARACTER SET 写GB2312 和gbk都可以,gbk优于gb2312.
对于新创建的数据库加个默认字符集声明GBK,就不用建表时候每个字段声明了,这样看起来简单流畅,没有特殊的痕迹,建议多采用这种方法.
<ol class="dp-xml">
<li class="alt">MySQL<span>(和PHP搭配之最佳组合)</span><span>> CREATE DATABASE dbCN DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; </span>
</li>
<li><span>CREATE TABLE `dbCN`.`cn` ( </span></li>
<li class="alt"><span>`zh` CHAR(10) NOT NULL, </span></li>
<li><span>`中文` INT(11) NOT NULL </span></li>
<li class="alt"><span>) </span></li>
<li>
<span class="attribute">ENGINE</span><span> = </span><span class="attribute-value">MYISAM</span><span>; </span>
</li>
<li class="alt">MySQL<span>(和PHP搭配之最佳组合)</span><span class="tag">></span><span> insert into cn values("真的？",1); </span>
</li>
</ol>注:如果这些脚本用bin/MySQL(和PHP搭配之最佳组合)命令行是输入不了,可以 用MySQL(和PHP搭配之最佳组合) query Browser,或者编程执行.
<ol class="dp-xml"> <li class="alt">shell> bin/MySQL<span>(和PHP搭配之最佳组合) -u root </span><span class="attribute">--default-character-set</span><span>=</span><span>gbk -p </span> </li> <li>MySQL<span>(和PHP搭配之最佳组合)</span><span class="tag">></span><span>use test </span> </li> <li class="alt">MySQL<span>(和PHP搭配之最佳组合)</span><span class="tag">></span><span> select * from cn; </span> </li> <li><span>+--------+------+ </span></li> <li class="alt"><span>| zh | 中文 | </span></li> <li><span>+--------+------+ </span></li> <li class="alt"><span>| 真的？| 1 | </span></li> <li><span>+--------+------+ </span></li> <li class="alt"><span>1 row in set (0.00 sec) </span></li> <li><span>--------------------------------------------- </span></li> </ol>
最后修改启动文件/etc/rc.d/rc.MySQL(和PHP搭配之最佳组合)
改路径/app/MySQL(和PHP搭配之最佳组合)/bin/MySQL(和PHP搭配之最佳组合)d_safe
改路径/app/MySQL(和PHP搭配之最佳组合)/var/web.pid
/app/MySQL(和PHP搭配之最佳组合)/bin/MySQL(和PHP搭配之最佳组合)d_safe 后面加入 --user=root --default-character-set=gbk
以上的相关内容就是对MySQL支持中文的介绍，望你能有所收获。
