ERROR 1698 (28000): Access denied for user ‘root‘@‘localhost‘ 已解决

Django起服务的时候 数据库报错

参考：https://blog.youkuaiyun.com/qq_35846773/article/details/80992155

sudo mysql -u root -p

进入数据库之后：

select user, plugin from mysql.user;

设置root的密码：

update mysql.user set authentication_string=PASSWORD('123'), plugin='mysql_native_password' where user='root';

刷新：

flush privileges;
