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“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 /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MySQL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
