主機Windows7下的MySQL workbench連接虛擬機MySQL出錯

問題：

主機Windows7下的MySQL workbench連接虛擬機MySQL出錯：Host '192.168.145.1' is not allowed to connect to this MySQL server

解決方法：

在虛擬機MySQL中，添加沒有權限連接的host，並授權

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.145.1' IDENTIFIED BY '密碼' WITH GRANT OPTION;

未授權之前：

mysql> select host,user from user;
+-----------+------+
| host      | user |
+-----------+------+
| %         | root |
| 127.0.0.1 | root |
| ::1       | root |
+-----------+------+
3 rows in set (0.05 sec)

授權後：

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.145.1' IDENTIFIED BY '123' WITH GRANT OPTION;
Query OK, 0 rows affected (0.07 sec)


mysql> select host,user from user;
+---------------+------+
| host          | user |
+---------------+------+
| %             | root |
| 127.0.0.1     | root |
| 192.168.145.1 | root |
| ::1           | root |
+---------------+------+
4 rows in set (0.00 sec)
