转自:http://blog.chinaunix.net/u2/85344/showart_2042280.html
Liunx下修改MySQL字符集：
1.查找MySQL的cnf文件的位置
find / -iname '*.cnf' -print
/usr/share/mysql/my-innodb-heavy-4G.cnf
/usr/share/mysql/my-large.cnf
/usr/share/mysql/my-small.cnf
/usr/share/mysql/my-medium.cnf
/usr/share/mysql/my-huge.cnf
/usr/share/texmf/web2c/texmf.cnf
/usr/share/texmf/web2c/mktex.cnf
/usr/share/texmf/web2c/fmtutil.cnf
/usr/share/texmf/tex/xmltex/xmltexfmtutil.cnf
/usr/share/texmf/tex/jadetex/jadefmtutil.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-innodb-heavy-4G.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-large.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-small.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-medium.cnf
/usr/share/doc/MySQL-server-community-5.1.22/my-huge.cnf
2. 拷贝 small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4G.cnf其中的一个到/etc下，命名为my.cnf
cp /usr/share/mysql/my-medium.cnf /etc/my.cnf
3. 修改my.cnf
vi /etc/my.cnf
在[client]下添加
default-character-set=utf8
在[mysqld]下添加
default-character-set=utf8
4.重新启动MySQL
[root@bogon ~]# /etc/rc.d/init.d/mysql restart
Shutting down MySQL [ 确定 ]
Starting MySQL. [ 确定 ]
[root@bogon ~]# mysql -u root -p
Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
5.查看字符集设置
mysq

1、解压 mysql-noinstall-5.1.30-win32.zip
2、在 F 盘建立目录 MySql\MySqlServer5.1\
3、把解压的内容复制到 F:\MySql\MySqlServer5.1\
4、在 F:\MySql\MySqlServer5.1\ 中找 my-large.ini 把它复制成 my.ini
5、在 my.ini 中找 [mysqld] ，添加以下语句;
basedir="F:/MySql/MySqlServer5.1/"
datadir="F:/My ......
一、MYSQL存储引擎大全：
·MyISAM：默认的MySQL插件式存储引擎，它是在Web、数据仓储和其他应用环境下最常使用的存储引擎之一。注意，通过更改STORAGE_ENGINE配置变量，能够方便地更改MySQL服务器的默认存储引擎。
·InnoDB：用于事务处理应用程序，具有众多特性，包括ACID事务支持。
·BDB：可替代I ......
