I want to start program when I enter my webpage, and problem is in permissions(??) because when I try
echo exec('whoami');
I've got valid response (www-data) but when i try code like it:
echo exec('/var/www/./sitesend');
and
echo passthru(/var/www/./sitesend');
I got no response. I tried to
chown www-data /var/www/sitesend
chmod 755 /var/www/sitesend
My C++ app runs correctly, and its sending by NRF infromations to turn lights. But not work, when enter page app won't run and I don't get any reps in echo.
我想在我进入网页时启动程序，问题在于权限（??），因为当我尝试
echo exec（'whoami'）;
我的回复有效（www-data） 但当我尝试这样的代码时：
echo exec（'/ var / www /./ sitesend'）;
\ n 和
echo passthru（/ var / www /./ sitesend'）;
我没有回应。 我试图
chown www-data / var / www / sitesend
chmod 755 / var / www / sitesend
我的C ++应用程序运行正常，并通过NRF infromations发送转向灯。
但是无法正常工作，当输入页面应用程序无法运行时，我不会在回显中获得任何代表。

I don't have a conclusive answer, but you can try a number of things:
Try the follow command to see if www-data may run the command.
微信扫一扫sudo -u www-data /var/www/sitesend
Try running a PHP script with the passthru command from the commandline.
See if you're running AppArmor for the Apache process. AppArmor will block execution for files not white listed.
ls /etc/apparmor.d
