centos下安装mysql之后中文乱码解决方案

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@lfl01 mysql]# cp my-medium.cnf /etc/my.cf

编辑my.cf 

[root@lfl01 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@lfl01 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！！
