Resolved Can't run php exec funtion on plesk running FastCGI application served by Apache

[davilson18]

Hello, I'm new in Plesk.
I'm dealing with issue about php funtion executive bash script like : shell_exec(), exec(), passthru(),...It always show error :"permission denied" when I config php setting "run php as FastCGI application served by Apache". But after I set php setting to "run php as FPM application served by nginx", php funtion above run perfectly. Anyone know why?
ps: php version : 5.6.30

I've had this issue and finally solved it reinstalling ffmpeg to a shared location. I happened to install it with 'root' user and followed this installation guide: CompilationGuide/Centos – FFmpeg
As 'root' user, the library installed at $HOME='/root/'. No problem for terminal commands. But problem for PHP because the user is not 'root' but 'apache' or 'httpd' or 'nginx'... and it has not permissions.
Solution: reinstall following that guide, but instead of '$HOME', using '/usr/local'. Now both terminal and php can access it with different users.

Yes, shell's access can be limited via php.ini. "open_basedir" for instance can do exactly that, and it is for security reasons.
