SQL Server 2005的cmd_shell组件的开启方法
SQL Server中的cmd_shell组件功能强大,几乎可通过该组建实现Windows系统的所有功能,正因此,这个组件也是SQL Server的最大安全隐患。SQL Server 2000中这个组件是默认开启的,而SQL Server 2005中这个组件默认作为此服务器安全配置的一部分而被关闭。有时我们需要用到该组件,开启此组件的相关语句如下:
代码如下:
--To allow advanced options to be changed. EXEC sp_configure 'show advanced options', 1 GO --To update the currently configured value for advanced options. RECONFIGURE GO -- To enable the feature. EXEC sp_configure 'xp_cmdshell', 1 GO --To update the currently configured value for this feature. RECONFIGURE GO
为了保证数据库服务器的安全,建议在使用完毕后关闭该组件,关闭该组件的相关语句如下:
代码如下:
--To allow advanced options to be changed. EXEC sp_configure 'show advanced options', 1 GO --To update the currently configured value for advanced options. RECONFIGURE GO -- To enable the feature. EXEC sp_configure 'xp_cmdshell', 0 GO --To update the currently configured value for this feature. RECONFIGURE GO
