修改MySQL中权限，为远程授权

在进入mysql之后，输入相应的语句：

GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘%‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;

其中‘myuser‘、‘mypassword‘ 需要替换成实际的用户名和密码。
例如GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘admin‘ WITH GRANT OPTION;

可能会报错，如下：

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

改正：

mysql> set password=password(‘admin‘);
Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘admin‘ WITH GRANT OPTION; FLUSH PRIVILEGES;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> quit;
Bye

成功修改
