以下的文章主要介绍的是让MySQL支持中文的实际操作方案,MySQL支持中文是随着MySQL数据库的产生而产生的也在一定程度上受到大家的青睐,以下就是具体内容的描述,希望在你今后的学习中会有所帮助。

提要:系统自带的MySQL(和PHP搭配之最佳组合)默认字符集不是gbk,因此给数据库的推广应用以及中文程序的开发带来极大的不便,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)

MySQL支持中文:下载MySQL(和PHP搭配之最佳组合)4.x.x

//-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, athlon, athlon-tbird, athlon-4, athlon-xp,athlon-mp,winchip-c6, winchip2 , c3.

shell> make

错误时候

shell> make clean

再回上一步

<ol class="dp-xml">

</li>
<li>
<span>shell</span><span class="tag">></span><span> ./bin/</span>MySQL<span>(和PHP搭配之最佳组合) -u root </span><span class="attribute">--default-character-set</span><span>=</span><span class="attribute-value">gbk</span><span> -p  </span>
</li>
<li class="alt">MySQL<span>(和PHP搭配之最佳组合)</span><span class="tag">></span><span> status  </span>

<li class="alt"><span>Server characterset: gbk  </span></li>
<li><span>Db characterset: gbk  </span></li>
<li class="alt"><span>Client characterset: gbk  </span></li>
<li><span>Conn. characterset: gbk  </span></li>
<li class="alt"><span>.... </span></li>
</ol>
Copy after login

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>
Copy after login

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>
Copy after login

MySQL支持中文注: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>
</ol>
Copy after login

最后修改启动文件/etc/rc.d/rc.MySQL(和PHP搭配之最佳组合)d

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
