Linux下MySQL5.6的修改字符集编码为UTF8（解决中文乱码问题）

Linux下MySQL5.6的修改字符集编码为UTF8（解决中文乱码问题）

 

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）：

 1、在[client]字段里加入default-character-set=utf8，如下：

 

[client]

port = 3306

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

default-character-set=utf8

 

2、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

 

3、在[mysql]字段里加入default-character-set=utf8，如下：

 

[mysql]

no-auto-rehash

default-character-set=utf8 

 

修改完成后，service mysql restart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。
