授予mysql服务器权限

Question

我正在尝试为MySQL服务器的IP地址授予权限。 我不知道怎么能完全因为我的英语而这么说，所以请耐心等待。

xx.xxx.xxx.xx - 我的IP

CREATE USER 'root'@'xx.xxx.xxx.xx' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'root@xx.xxx.xxx.xx' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

我得到的这个错误：

#1227 - Access denied; you need the CREATE USER privilege for this operation 

有人可以帮帮我吗？

编辑：

我发了命令

SHOW GRANTS;

Grants for sukup-parkety@localhost
GRANT USAGE ON *.* TO 'sukup-parkety'@'localhost' IDENTIFIED BY PASSWORD 'somepassword'
GRANT ALL PRIVILEGES ON `sukup\_parkety`.* TO 'sukup-parkety'@'localhost' WITH GRANT OPTION

编辑2：好的，所以我做了其他命令

GRANT ALL ON sukup_parkety.* TO 'root@xx.xxx.xxx.xx' IDENTIFIED BY 'mypassword';

但它报告长度错误？

#1470 - String 'root@xx.xxx.xxx.xx' is too long for user name (should be no longer than 16) 

Answer 1

尝试'root'@'xx.xxx.xxx.xx'而不是'root@xx.xxx.xxx.xx'

Answer 2

是的，要授予的确切查询是：

GRANT ALL ON sukup_parkety.* TO 'root'@'xx.xxx.xxx.xx' IDENTIFIED BY 'mypassword';

只是重复已经说过并希望upvote。
