【中文标题】MySQL：为 CREATE 授予权限被拒绝

【英文标题】：MySQL: grant permissions denied for CREATE

【问题描述】：

我像往常一样设置了数据库和用户以及授予权限，但我仍然被拒绝访问，我不知道为什么：

[root@server23 redditonrails]# mysql -u redditonrails -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 431954

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> use redditonrails_development;
Database changed
mysql> create table test;
ERROR 1142 (42000): CREATE command denied to user 'redditonrails'@'localhost' for table 'test'
mysql> show grants;

【问题讨论】：

另外，您可能希望在创建表时添加一列。可能是这样...

刚试了，没修。

mysql> 创建表测试（id INT）； ERROR 1142 (42000): CREATE command denied to user 'redditonrails'@'localhost' for table 'test'

【参考方案1】：

我不相信你的语法是正确的。您正在指定：

授予所有权限 redditonrails_development.localhost

db 级 GRANT 的预期语法为：ON $db.$table。基于此，您只授予名为“localhost”的表。改为：

授予所有权限 redditonrails_development.*

【参考方案2】：

您的用户 redditonrails 似乎拥有所有特权 redditonrails_development.localhost

这意味着redditonrails_development 数据库和localhost 表。你想要的就是在那里

redditonrails_development.*

witch 意味着您在所有表上都拥有所有特权（甚至是您尝试创建的新表）

至少我是这么看的。
