Hi. I have configured Debian 9 Perfect Server and I want to use PHP FPM for 5.6, 7.0, 7.1 and 7.2 installed from this HowTo on tcp port. Can you you provide me a workaround to do this? I want to use different versions of PHP-FPM for different websites. Is it possible? My current ISPConfig version is 3.1.9 Aditional PHP version was added on System > Additional PHP Versions. For example PHP 7.1: == FastCGI settings: - Path to the PHP FastCGI binary: /usr/bin/php-cgi7.1 Path to the php.ini directory: /etc/php/7.1/cgi == PHP-FPM settings: - Path to the PHP-FPM init script: /usr/sbin/php-fpm7.1 Path to the php.ini directory: /etc/php/7.1/fpm Path to the PHP-FPM pool directory: /etc/php/7.1/fpm/pool.d Default PHP-FPM work on tcp port 9011 but it is for PHP 7.0. When I try to set PHP-FPM and PHP 7.1 in error log file I get error: PHP: [Sat Dec 09 12:56:55.810379 2017] [proxy_fcgi:error] [pid 14466] [client 188.8.131.52:52254] AH01079: failed to make connection to backend: httpd-UDS[Sat Dec 09 12:57:13.346779 2017] [proxy:error] [pid 14669] (111)Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1:9011 (*) failed So, in website settings when I set PHP-FPM and "Default" its work. But when I set PHP-FPM and select PHP 7.1 I got errror. I apologize and thank you for your time.
