解决 ubuntu mysql 中文乱码

mysql配置文件更改：

ubuntu：/etc/mysql/my.cnf

[mysqld] 
init_connect='SET collation_connection = utf8_unicode_ci' 
init_connect='SET NAMES utf8' 
character-set-server=utf8 
collation-server=utf8_unicode_ci 
skip-character-set-client-handshake

重启服务

sudo /etc/init.d/mysql restart

执行命令mysql

mysql> show variables like "%character%";show variables like "%collation%";

如果还是中文乱码，可能是数据库建立的时候使用的是默认编码latin

用一下语句可以更改字段的编码：

ALTER TABLE `${table}` CHANGE `${column}` `${column}` VARCHAR( 45 ) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL 

其他：

1.修改库的编码： ALTER DATABASE `${db}` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin

2.修改表的编码：ALTER TABLE `${table}` DEFAULT CHARACTER SET utf8 COLLATE utf8_bin 

${table},${column},${db} 这个是什么你们懂得
