linux - 用php的exec()删除目录文件提示权限不够

Jun 06, 2016 pm 08:29 PM
exec linux php Permissions

我在用浏览器访问服务器上的php文件,然后用exec()删除某目录文件,提示权限不够,经过一顿搜索之后,我已根据很多文章的描述进行下面的权限设置,请问还有什么漏了设置的地方导致权限还是不够?

代码test.php:
$a = exec("rm /var/test/test.txt 2>&1",$result,$status);
print_r($result);
关于权限的服务器设置:
1、apache的httpd.conf中的user和group现在是apache。

2、利用visudo给了apache和root一样的权限,并把Defaults requiretty注释了。

3、将/var/test文件夹的权限给足,用户和用户组设为apache

4、test.txt的权限和用户、用户组也设置了

访问192.168.1.xxx/test.php还是不能删掉,还是提示这个:

通过

<code><?php echo shell_exec('whoami');
</code></code>
Copy after login

你就可以知道为何你没有权限删除了啊
另外, 在PHP中直接创建一个文件, 看看他是什么权限,也能看到你的php的执行用户和用户组

根据上面的权限配置,应该是能删除的呀。
LZ要不试试重启下apache服务器,然后再执行代码。

注意到php.ini里提供有一个open_basedir配置,也就是只有在open_basedir里的目录,PHP才能进行操作,所以如果你开启了open_basedir限制,那你就应该把/var/test这个目录加到open_basedir里,重启Apache:

<code>open_basedir="/tmp/:/var/www/html/:/var/test/"
</code>
Copy after login

Linux上目录用冒号(:)分隔,Windows上用分号(;)分隔.

很奇怪,你把apache加入了visudo里,为什么sudo -u apache 还是不能删除文件?也就是说sudo并没有成功赋给apache这个用户了

Linux Architecture: Unveiling the 5 Basic Components Linux Architecture: Unveiling the 5 Basic Components Apr 20, 2025 am 12:04 AM

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

The Continued Use of PHP: Reasons for Its Endurance The Continued Use of PHP: Reasons for Its Endurance Apr 19, 2025 am 12:23 AM

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

Docker on Linux: Containerization for Linux Systems Docker on Linux: Containerization for Linux Systems Apr 22, 2025 am 12:03 AM

Docker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex

The Compatibility of IIS and PHP: A Deep Dive The Compatibility of IIS and PHP: A Deep Dive Apr 22, 2025 am 12:01 AM

IIS and PHP are compatible and are implemented through FastCGI. 1.IIS forwards the .php file request to the FastCGI module through the configuration file. 2. The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

What happens if session_start() is called multiple times? What happens if session_start() is called multiple times? Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How to understand DMA operations in C? How to understand DMA operations in C? Apr 28, 2025 pm 10:09 PM

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.

Composer: Aiding PHP Development Through AI Composer: Aiding PHP Development Through AI Apr 29, 2025 am 12:27 AM
