[讨论]让MySql彻底支持中文(linux下)

系统自带的mysql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"置顶贴",然后重新编译mysql,原来系统mysql的要先用卸载. login:root
shell> removepkg mysql shell> groupadd mysql shell> cd /app shell> mkdir mysql shell> chmod 744 mysql shell> useradd -G mysql -s /bin/bash –p /app/mysql mysql shell> chown -R mysql.mysql mysql
 下载mysql4.x.x
shell> gunzip < mysql-VERSION.tar.gz | tar -xvf - shell> cd mysql-VERSION shell> CFLAGS="-O3 -mcpu=pentium3" \ CXX=gcc \ XXFLAGS="-O3 -mcpu=pentium3 -felide-constructors" \ ./configure --prefix=/app/mysql \ --with--charset=gbk \ --with-extra-charsets="gbk gb2312 big5 utf8"\ --with-unix-socket-path=/etc/mysql.sock \ --enable-local-infile \ --enable-thread-safe-client \ --enable-assembler \ --with-client-ldflags=-all-static \ --with-mysqld-ldflags=-all-static 
//-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 ------------------------------------------------------------ shell> make install shell> cp support-files/my-medium.cnf /etc/my.cnf shell> cd /app/mysql shell> bin/mysql_install_db --user=root
shell> chown -R root . shell> chown -R mysql var shell> chgrp -R mysql . shell> ./bin/mysqld_safe --user=root --default-character-set=gbk & shell> ./bin/mysqladmin -u root password 'new-password' shell> ./bin/mysql -u root --default-character-set=gbk -p 
mysql> status ... Server characterset: gbk Db characterset: gbk Client characterset: gbk Conn. characterset: gbk .... 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 CREATE TABLE `test`.`cn` ( `zh` CHAR(10) CHARACTER SET gb2312 COLLATE gb2312_chinese_ci NOT NULL, `中文` INT(11) NOT NULL ) ENGINE = MYISAM; 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. mysql> CREATE DATABASE dbCN DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci;
CREATE TABLE `dbCN`.`cn` ( `zh` CHAR(10) NOT NULL, `中文` INT(11) NOT NULL ) ENGINE = MYISAM;
mysql> insert into cn values("真的？",1); 注:如果这些脚本用bin/mysql命令行是输入不了,可以用mysql query Browser,或者编程执行. -------------------------------------------------------------------------------------------------------- shell> bin/mysql -u root --default-character-set=gbk -p
mysql>use test mysql> select * from cn; +--------+------+ | zh | 中文 | +--------+------+ | 真的？ | 1 | +--------+------+ 1 row in set (0.00 sec)
--------------------------------------------- 最后修改启动文件/etc/rc.d/rc.mysqld
改路径/app/mysql/bin/mysqld_safe 改路径/app/mysql/var/web.pid
/app/mysql/bin/mysqld_safe 后面加入 --user=root --default-character-set=gbk

那位高人参考上文写个windowsXP下的，多谢了！ linux实在是搞不懂啊！
