  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

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

New Pleskian
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.
