最近在CentOS下安装MySQL程序之后，导入数据发现有中文异常，将解决办法整理出来以便日后参考：
步骤如下：
第一、安装mysql之后默认的字符编码为latin1
登录mysql之后可以通过 show variables like '%char%'查看，显示如下
+---------------------－+-----－－--------------
| Variable_name | Value
+-----------------------+-－－------------------
| character_set_client | latin1
| character_set_connection | latin1
| character_set_database | latin1
| character_set_filesystem | binary
| character_set_results | latin1
| character_set_server | latin1
| character_set_system | utf8
| character_sets_dir | /usr/share/mysql/charsets/
+---------------------+－－－-------------------
第二、进入/usr/share/mysql目录之后，拷贝my-medium.cnf 到/etc下
[root@linuxidc mysql]# cp my-medium.cnf /etc/my.cf
编辑my.cf
[root@linuxidc mysql]# vim my.cf
在最后添加：
[client]
default-character-set=utf8
[mysqld_safe]
default-character-set=utf8
[mysqld]
default-character-set=utf8
[mysql]
default-character-set=utf8
保存退出。
第三、重启mysql服务
[root@linuxidc mysql]# /etc/init.d/mysql restart
第四、登录mysql之后 再次通过show variables like '%char%'查看，显示如下
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
OK 解决完毕！！
