CentOS6 修改MySQL编码

1、查看编码格式
show variables like 'character%';

+--------------------------+----------------------------+
| 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/ |
+--------------------------+----------------------------+

2、复制my-large.cnf文件到/etc/my.cnf
cp /usr/share/doc/mysql-server-4.1.12/my-large.cnf  /etc/my.cnf

3、打开my.cnf修改编码
vi /etc/my.cnf
在[mysqld]下添加(5.1版本)
default-character-set=utf8

如果是5.5以上版本则添以下配置
character-set-server=utf8
collation-server=utf8_general_ci


在[client]下添加
default-character-set=utf8


4、重启MySQL服务
service mysqld restert

5、登录mysql看看修改成功否
 show variables like 'character%';
+--------------------------+----------------------------+
| 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 (0.00 sec)
如果显示以上信息表示修改成功了
