System interaction - Does nginx have a module that can call system commands?

Question

Recently, I want to use Nginx to make a simple system management interface, which is to call system commands through RPC. Then return the system output (both error and standard output).
If you use PHP or Perl, I know you can use their system interactive interface, but I don't want to introduce a script. Is there a direct way to call Nginx?
Or is there any Nginx module that supports this kind of system interaction?
