mysql 8 设置允许远程连接 You are not allowed to create a user with GRANT

 

1.登录mysql :   mysql -u root -p

2.输入密码：    Enter password:  xxxxx

       ------ Server version: 8.0.15 MySQL Community Server - GPL

3.进入mysql数据库：use mysql;

4.设置允许远程用户访问：   

MySQL [mysql]> GRANT ALL ON *.* TO 'root'@'%'

出现问题：ERROR 1410 (42000): You are not allowed to create a user with GRANT

原因：当前user表中没有root - %记录； 可以更新root - localhost 为 root - %

   

 

MySQL [mysql]> update user set host = '%' where user = 'root';
出现问题：ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'
