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：

 

?

1 2 3 4 5 6 7 8 9 10 11 12

+ --------------------------+----------------------------+ | 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 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

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。
