The vhost file generated is wrong for PHP-FPM. When I select use socket under options, the FastCgiExternalServer still uses TCP. Any suggestions?
That's a known issue, some FCGI versions do not support sockets, so ISPConfig switches to TCP in this case to prevent that the server fails.
This was using the default php-fpm from Debian Stretch 9.1 which automatically uses sockets... All my php versions support sockets (5.6, 7.0, 7.1 and 7.2), how can I force to use sockets?
you can't without changing the ispconfig source code (apache or ngnx plugin, depending on your server setup).
So I can't force it in the config template? What check do you do to test if FCGI supports sockets (maybe I can bypass it there)? P.S.: I am using apache.
I just took a look in the code and the restriction to force port based connections has been removed already. I guess you don't use the latest ISPConfig version 3.1.6?
You were right, at the time I didn't use ISPConfig 3.1.6. To avoid loss of time for both of us, I upgraded and tried to test the new setup. However it still doesn't work... PHP-FPM works fine with own compiled versions of php. However it does not work with the official Debian version, thus I guess it is a configuration problem. As the configuration is different for the default and the custom php versions, it is hard to compare... any suggestion is welcome! Thanks, Yves
