Mysql 授予所有权限未得到应用

Question

我发出以下命令以允许从任何主机进行 root 登录

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'xxxx' WITH GRANT OPTION;
FLUSH PRIVILEGES;

但它不更新？

mysql> show grants;
+----------------------------------------------------------------------------------------------------------------------------------------+
| Grants for root@localhost                                                                                                              |
+----------------------------------------------------------------------------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*xxxxxxxxxxxxxxxxx33487256' WITH GRANT OPTION |
| GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION                                                                           |

Answer 1

我怀疑这是因为您在以 root 身份连接到本地主机时发出“show grants”命令。尝试一下并查看返回的内容:

SHOW GRANTS FOR 'root'@'%';

如果没有显示任何内容，请查看 mysql.user 表，其中可能有线索:

SELECT user, host FROM mysql.user;
