hint not found

At first I thought it was a problem with php compilation and installation, so I went to the php directory to execute php-fpm, and everything was normal

Basically exclude php problems

Solution

Finally searchedservice Command information to find a solution

In ubuntu 16.04, in addition to copying the file to the /etc// directory, adding a service also requires the following command

 echo -n "Gracefully shutting down php-fpm "

 if [ ! -r $php_fpm_PID ] ; then
  echo "warning, no pid file found - php-fpm is not running ?"

 kill -QUIT `cat $php_fpm_PID`

 wait_for_pid removed $php_fpm_PID

 if [ -n "$try" ] ; then
