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 = 3306socket = /var/lib/mysql/mysql.sockdefault-character-set=utf82、在[mysqld]字段里加入character-set-server=utf8,如下:[mysqld]port = 3306socket = /var/lib/mysql/mysql.sockcharacter-set-server=utf83、在[mysql]字段里加入default-character-set=utf8,如下:[mysql]no-auto-rehashdefault-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。

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