SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client

运行报如下错误是因为docker默认安装mysql是8.0以上最新版本，需要修改mysql密码验证规则

SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client

解决方法:

#进入mysql容器 docker exec -it mysql /bin/bash #登陆数据库 mysql -u root -p use mysql; #开启root远程访问权限 grant all on *.* to 'root'@'%'; #修改加密规则 alter user 'root'@'localhost' identified by '123456' password expire never; #更新密码 alter user 'root'@'%' identified with mysql_native_password by '123456'; #刷新权限 flush privileges;
