mysql8.0無法給用戶授權或提示You are not allowed to create a user with GRANT的問題

mysql> CREATE USER 'root'@'%' IDENTIFIED BY 'Hadoop3!'; Query OK, 0 rows affected (0.04 sec) mysql> grant all privileges on *.* to 'root'@'%'; Query OK, 0 rows affected (0.03 sec)

另外，如果遠程連接的時候報plugin caching_sha2_password could not be loaded這個錯誤，可以嘗試修改密碼加密插件：

 mysql> alter user 'root'@'%' identified with mysql_native_password by 'Hadoop3!';
