本文主要详细介绍一下Linux下彻底解决MySQL中文乱码问题,一般乱码问题出现在服务器首次安装MySQL中。

Linux下彻底解决MySQL中文乱码

执行查询语句发现查询的数据中中文的都是乱码

//使用该命令查看编码，发现好多编码不是utf8
SHOW VARIABLES LIKE 'char%';

//修改编码
set character_set_results=utf8;

//再次查询发现乱码解决，但并不是永久解决，退出mysql再次登录mysql还是乱码

永久解决乱码问题

cat /etc/mysql/mysql.conf.d/mysqld.cnf

可能不是该文件名，或者有些内容会有些出入，找到跟下图内容差不多的文件就可以，将红框的内容添加到文件中

修改完成之后保存并退出便可以永久生效

mysqld.cnf文件内容
