SQLyog Ultimate - MySQL GUI v12.09（64 bit）连接mysql8时报错，已解决

1、报错截图

2、解决方法

解决方法： 一种是升级SQLyog和Navicat（新版SQLyog和Navicat不会出现此问题），另一种是把MySQL用户登录密码加密规则还原成mysql_native_password。

2.1、连接数据库

C:\Users\dgq>mysql -uroot -p
Enter password: ******

2.3、ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘123456’;

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.01 sec)

2.4、flush privileges;

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

3、连接SQLyog
