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
