PHP-FPM is a deployment methodology of PHP known as FastCGI Process Manager, which permits PHP to run considerably extra effectively than by way of sure different libraries. Ultimately whereas nginx just isn’t the default internet server put in on the affected working programs from QNAP, it doesn’t imply nginx could not be put in anyway. The following are the affected QNAP working system variations.

  • QTS 5.0.x
  • QTS 4.5.x
  • QuTS hero h5.0.x
