mySQL修改编码

一、登录MySQL查看用SHOW VARIABLES LIKE ‘character%’;下字符集，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 | latin1 |

| character_set_system | utf8 |

| character_sets_dir | /usr/share/mysql/charsets/|

+--------------------------+----------------------------+

 

character_set_database和character_set_server的默认字符集还是latin1。

二、最简单的完美修改方法，修改mysql的my.cnf文件中的字符集键值（注意配置的字段细节）

在[mysqld]字段里加入character-set-server=utf8，如下：

[mysqld]

port = 3306

socket = /var/lib/mysql/mysql.sock

character-set-server=utf8

修改完成后，service mysqlrestart重启mysql服务就生效。注意：[mysqld]字段与[mysql]字段是有区别的。这点在网上没人反馈过。

 

使用SHOW VARIABLES LIKE ‘character%’;查看，发现数据库

编码全已改成utf8。

 

+--------------------------+----------------------------+

| 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/|

+--------------------------+----------------------------+

三： 如果character-set-client 不为utf8，增加如下设置：

[client]

default-character-set=utf8

四： 如果character_set_filesystem不为utf8， 增加如下设置：

​character-set-filesystem = utf8
