[proxy:error] No such file or directory: AH02454: FCGI: adding a 2nd php (5.6)

Hi all,
I had to install PHP 5.6 due to old software. I followed the tutorial at:
https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/
which suppose to cover Debian 10 too.
I did exactly what the tutorial says; PHP 7 works fine but 5.6 doesn't. It throws the following error:

Code:

[Sat Sep 26 10:26:20.294362 2020] [proxy:error] [pid 20784] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /var/lib/php7.3-fpm/web18.sock (*) failed
[Sat Sep 26 10:26:20.294449 2020] [proxy_fcgi:error] [pid 20784] [client 178.147.196.46:54112] AH01079: failed to make connection to backend: httpd-UDS

It seems that it is searching for PHP 7 while I've got that site configured via ISPconfig admin to use PHP 5.6 fpm. The above tutorial had wrong the paths for Debian 10 so I've adjusted them properly (PHP is under /etc/php/5.6/fpm/ and not on those listed on the tutorial).
Switching to PHP-cgi works but it doesn't on FPM.

Any help is very much appreciated.

Thanks

 

The service is running from what I can tell.

Code:

@till I've restarted the service many times without any luck. It seems that somehow the process was still running.
Once I stopped completely the service and started again it worked. Very strange.

Thanks a lot

 

On Debian 10, you should stop using command service to stop and start services. Instead use systemctl, like

Code:

systemctl status php5.6-fpm
systemctl stop php5.6-fpm
systemctl start php5.6-fpm
