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. 拷貝 small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4G.cnf其中的一個(gè)到/etc下，命名為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.重新啟動(dòng)MySQL
[root@bogon ~]# /etc/rc.d/init.d/mysql restart
Shutting down MySQL                                         [ 確定 ]
Starting MySQL.                                             [ 確定 ]
[root@bogon ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.1.22-rc-community-log MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

5.查看字符集設(shè)置
mysql> show variables like 'collation_%';
+----------------------+-----------------+
| Variable_name         | Value            |
+----------------------+-----------------+
| collation_connection | utf8_general_ci |
| collation_database    | utf8_general_ci |
| collation_server      | utf8_general_ci |
+----------------------+-----------------+
3 rows in set (0.02 sec)
mysql> show variables like 'character_set_%';
+--------------------------+----------------------------+
| Variable_name             | Value                       |
+--------------------------+----------------------------+
| character_set_client      | utf8                        |
| character_set_connection | utf8                        |
| character_set_database    | utf8                        |
| character_set_filesystem | binary                      |
| character_set_results     | utf8                        |
| character_set_server      | utf8                        |
| character_set_system      | utf8                        |
| character_sets_dir        | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.02 sec)
