为什么 GRANT 在 MySQL 中不起作用?
我对此感到摸不着头脑,因为我看到大量的帮助网站展示了如何创建 MySQL 用户和授予权限,但由于某种原因它对我不起作用。我在安装了最新 MySQL 版本的 WinXP 和 MacBook Pro 笔记本电脑上进行了尝试。
以下只是我使用 WordPress 时的一个示例。实际的数据库有所不同,但存在相同的问题。
步骤如下:
mysql> mysql -uroot -p<password>
mysql> CREATE DATABASE wwordpress;
mysql> CREATE USER 'www'@'localhost' IDENTIFIED BY 'basic';
查询正常,受影响 0 行(0.14 秒)
mysql> GRANT INSERT ON wordpress.* TO 'www'@'localhost' IDENTIFIED BY 'basic';
查询正常,受影响 0 行(0.00 秒)
mysql> FLUSH PRIVILEGES;
查询正常,受影响 0 行(0.03 秒)
mysql> SELECT * FROM mysql.user WHERE User='www' \G
*************************** 1. row *************************** Host: localhost User: www Password: *E85C94AF0F09C892339D31CF7570A970BCDC5805 Select_priv: N Insert_priv: N Update_priv: N Delete_priv: N Create_priv: N Drop_priv: N Reload_priv: N Shutdown_priv: N Process_priv: N File_priv: N Grant_priv: N References_priv: N Index_priv: N Alter_priv: N Show_db_priv: N Super_priv: N Create_tmp_table_priv: N Lock_tables_priv: N Execute_priv: N Repl_slave_priv: N Repl_client_priv: N Create_view_priv: N Show_view_priv: N Create_routine_priv: N Alter_routine_priv: N Create_user_priv: N Event_priv: N Trigger_priv: N ssl_type: ssl_cipher: x509_issuer: x509_subject: max_questions: 0 max_updates: 0 max_connections: 0 max_user_connections: 0 1 row in set (0.00 sec) mysql>
如您所见,“Insert_priv: N”应该是“Y”。
有什么建议吗?
提前致谢。
I'm scratching my head on this one as I see a ton of helper websites showing how to create MySQL users and grant privileges but for some reason it just does not work for me. I tried on both WinXP and a MacBook Pro laptop with the latest MySQL version installed.
The following is just an example from when I worked with WordPress. The actual database is something different but same issues.
Here are the steps:
mysql> mysql -uroot -p<password>
mysql> CREATE DATABASE wwordpress;
mysql> CREATE USER 'www'@'localhost' IDENTIFIED BY 'basic';
Query OK, 0 rows affected (0.14 sec)
mysql> GRANT INSERT ON wordpress.* TO 'www'@'localhost' IDENTIFIED BY 'basic';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.03 sec)
mysql> SELECT * FROM mysql.user WHERE User='www' \G
*************************** 1. row *************************** Host: localhost User: www Password: *E85C94AF0F09C892339D31CF7570A970BCDC5805 Select_priv: N Insert_priv: N Update_priv: N Delete_priv: N Create_priv: N Drop_priv: N Reload_priv: N Shutdown_priv: N Process_priv: N File_priv: N Grant_priv: N References_priv: N Index_priv: N Alter_priv: N Show_db_priv: N Super_priv: N Create_tmp_table_priv: N Lock_tables_priv: N Execute_priv: N Repl_slave_priv: N Repl_client_priv: N Create_view_priv: N Show_view_priv: N Create_routine_priv: N Alter_routine_priv: N Create_user_priv: N Event_priv: N Trigger_priv: N ssl_type: ssl_cipher: x509_issuer: x509_subject: max_questions: 0 max_updates: 0 max_connections: 0 max_user_connections: 0 1 row in set (0.00 sec) mysql>
As you can see "Insert_priv: N" should be "Y".
Any suggestions?
Thanks in advance.

您选择的是全局权限。
然而,您授予数据库(和主机,但这并不重要)特定的权限。
GRANT INSERT
ON wordpress
.* TO 'www'@'localhost' IDENTIFIED BY 'basic';
这些权限存储在
db
表中。只是为了向您指出正确的方向:
http://dev. mysql.com/doc/refman/5.0/en/show-grants.html
What you are selecting are the global privileges.
You are however giving database (and host, but that doesn't matter) specific privileges.
GRANT INSERT
ON wordpress
.* TO 'www'@'localhost' IDENTIFIED BY 'basic';
These permissions are stored in the
db
table.Just to point you in the right direction:
http://dev.mysql.com/doc/refman/5.0/en/show-grants.html
这不是存储大多数用户授予的权限的地方 - 尝试
查看特定于数据库的权限。 (如果授权仅适用于所有数据库,则只会显示在用户表中。)
这是 如何在 MySQL 中存储权限 - 我认为事情没有太大变化。
That's not where the most user GRANTed rights are stored - try
to see database-specific permissions instead. (A grant would only show up in the user table if it was for all databases.)
Here's a (rather old) step-by-step detail of how permissions are stored in MySQL - I don't think things have changed much.
这应该有效:
This should work:
如果您需要选择 Y 或 N,如果您尝试对用户可以编辑、插入或删除的页面进行一些限制,则需要查看 mysql.db 或 mysql.tables_priv 表...此表会自动更新使用 Y 和 N 是因为它们只是为了显示用户对表或列拥有的权限,而不是 mysql.user,后者的目的是显示某个用户可以登录(创建连接)数据库。
You need to look at mysql.db or mysql.tables_priv tables if you need to select the Y or N if you are trying to do some restrictions of from what page a user can edit or insert or delete... This tables are automatically updated with the Ys and Ns as they are solely designed to show what privileges a user has on tables or columns as opposed to mysql.user whose purpose is to show that there is a certain user who can login(create connection) to a database.
是的,我同意我创建了 2 个用户并授予他们对数据库的所有权限,但不知怎的,只有一个用户会收到升级的权限,无论我做什么,第二个用户都不会收到权限,尽管我试图授予以与第一个用户完全相同的方式授予用户权限,然后我刷新了权限
Yes I agree I created 2 users and granted them all privileges on the database but somehow only one of the users will receive the upgraded privileges, no matter what I do the second user will not receive the privileges despite the fact that I tried to grant the privileges to the user in exactly the same way that worked with the first user and I flushed the privileges afterwards
