如何在PHP中执行Shell脚本? [英] How to execute a shell script in PHP?

问题描述

我在/var/www/myscript.sh 中有一个脚本，该脚本创建文件夹并为我的项目运行命令svn update.我需要通过在浏览器中的PHP文件(即 Localhost/test.php )中调用该脚本来执行该脚本.我尝试使用功能shell_exec()和exec()，但是这些功能不起作用.我用su www-data && ./myscript.sh在终端中运行了我的shell脚本，它起作用了.我还想念什么?

I have a script in /var/www/myscript.sh which creates folders and runs the command svn update for my projects. I need to execute this script by calling it in a PHP file in the browser (i.e. Localhost/test.php). I tried using functions shell_exec() and exec() but those did not work. I ran my shell script in terminal with su www-data && ./myscript.sh and it worked. What else am I missing?

<?php
$output = shell_exec("./myscript.sh");
?>

我在/etc/sudoers中添加了www-data ALL=(ALL) NOPASSWD:ALL，它可以工作，但这是非常不安全的.还有另一种方法吗?

I added www-data ALL=(ALL) NOPASSWD:ALL to /etc/sudoers and it works, but this is very insecure. Is there another way to do this?

推荐答案

多种可能性:

• 您已启用安全模式.这样，只有exec()起作用，然后才在

• You have safe mode enabled. That way, only exec() is working, and then only on executables in safe_mode_exec_dir
• exec and shell_exec are disabled in php.ini
• The path to the executable is wrong. If the script is in the same directory as the php file, try exec(dirname(__FILE__) . '/myscript.sh');
