PHP-FPM reload / restart problems

short description

Default PHP version: 5.6 Additional PHP version: 7.0

Sometimes when switching PHP version for a website, the site isn't reachable after that. I need to manual restart PHP-FPM in the specific version, where the site should run. By inspecting the code, i also realized that the given init scripts /etc/init.d/php5-fpm or /etc/init.d/php-7-fpm are getting translated into service php5-fpm reload.

The log files are 'clean' and don't show any problems. The main problem may be the 'reload' as it may not reload the config itself. Restart would be better as a reload may not be that gracefull

correct behaviour

Switching shouldn't cause a broken connection for PHP-FPM socket.

environment

Server OS: debian Server OS version: jessio 8.7 ISPConfig version: 3.1.3

solution / improvements

1.) Really keep the the init script and don't manipulate it, so it's users choice if they enter '/etc/init.d/...' or 'service ..."

2.a) Make another option, if changes should call a reload or restart

2.b) If you really need the init script from 1.) make additional fields for command of reload/restart that should be used.

I will try to provide a solution merge, but as time is really rare right now, i'll can't promise.
