Raspberry PI:PHP使用sudo调用python脚本 [英] Raspberry PI: PHP call python script with sudo
问题描述
我正在使用PHP 5.4.14(fpm-fcgi)在我的Raspberry PI上运行Nginx.一切都很好.但是在一个脚本中,我使用shell_exec进行了shell调用.
i'm running Nginx on my Raspberry PI with PHP 5.4.14 (fpm-fcgi). It all works well. But in one script i make a shell call using shell_exec.
echo shell_exec("sudo python " . $file);
如果我将控制台与
php test.php
但是如果我使用浏览器调用此文件,将执行php文件,但shell_exec不会输出任何信息(甚至没有错误消息).
but if i use the browser to call this file the php-file will be executed but i don't get any output by the shell_exec (not even an error message).
所以我希望你能帮助我解决这个问题.
So i hope you could help me fix this problem.
被调用的python文件使用GPIO,因此需要sudo,对吧?
The called python file makes use of the GPIO so sudo is required, right?
这是我的python代码:
Here is my python code:
#!/usr/bin/env python
try:
import RPi.GPIO as GPIO
except RuntimeError:
print "Error Importing GPIO. Did your forgot the superuser privilieges?"
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
GPIO.setup(3, GPIO.OUT)
GPIO.output(3, not GPIO.input(3))
print "New LED state is: ", GPIO.input(3)
#GPIO.cleanup()
推荐答案
供以后参考:
我发现-我的眼睛-不太好的解决方法:
I found a - i my eyes - not really nice solution:
sudo echo "apache ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
