系統(tǒng)自帶的mysql默認字符集不是gbk,因此給數(shù)據庫的推廣應用以及中文程序的開發(fā)帶來極大的不便,在沒完沒了的GBK和UTF8的轉換過程中消耗了我們無數(shù)的精力以及系統(tǒng)的資源.經過摸索嘗試解決了中文支持問題,經驗與大家分享一下.
先將讓slack支持中文,方法可以看"linuxsir.org 之Slackware討論區(qū)",然后重新編譯mysql,原來系統(tǒng)mysql的要先用卸載. 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 下載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 根據CPU類型優(yōu)化編譯，可以讓你的mysq表現(xiàn)更好！可選項目很多：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 ------------------ 錯誤時候 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 ....看見characterset全是gbk就算成功了. -----------
在UTF8字符集的老數(shù)據庫中,創(chuàng)建中文支持表腳本如下,對字段加上字符集說明
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 寫GB2312 和gbk都可以,gbk優(yōu)于gb2312.
對于新創(chuàng)建的數(shù)據庫加個默認字符集聲明GBK,就不用建表時候每個字段聲明了,這樣看起來簡單流暢,沒有特殊的痕跡,建議多采用這種方法.
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:如果這些腳本用bin/mysql命令行是輸入不了,可以 用mysql query Browser,或者編程執(zhí)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)
----------------------
最后修改啟動文件/etc/rc.d/rc.mysqld
改路徑/app/mysql/bin/mysqld_safe 改路徑/app/mysql/var/web.pid
/app/mysql/bin/mysqld_safe 后面加入 --user=root --default-character-set=gbk |
