//-mcpu 根據CPU類型優化編譯,可以讓你的MySQL表現更好! 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

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字符集的老數據庫中,創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優于gb2312。
對于新創建的數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。
