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,原来系统mysql的要先用卸载.
login:root
shell> removepkg mysql
shell> groupadd mysql
shell> cd /appshell> mkdir mysqlshell> chmod 744 mysqlshell> useradd -G mysql -s /bin/bash –p /app/mysql mysqlshell> 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=gccXXFLAGS="-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/mysqlshell> bin/mysql_install_db --user=rootshell> chown -R root .shell> chown -R mysql varshell> 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 -pmysql> status...Server characterset: gbkDb characterset: gbkClient characterset: gbkConn. 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
