lighttpd 1.4.47 : (gw_backend.c.478) unlink /var/run/lighttpd/x-fastcgi.socket-0 after connect failed: Connection refused
Added by shuchi over 5 years ago
Start receiving these errors after few hours of lighttpd start. There are initially 24 fastcgi processes running and they keep shutting down after above errors until none of the process reman.
The lighttpd process in itself keeps running.
Here is the lighttpd.conf

The latest version is lighttpd 1.4.52. Please test with that version to see if your issue has already been fixed.

Hi
I have similar message, as you indicated here above
In my case I get the message immediately after starting up the lighttpd server
In the error log it, looks like a continuous retry that is failing
I run with lighttpd 1.4.53
Can you indicate if you found a solution for the above issue?
Kind regards,

That sounds like something different: the script that starts your backend is broken or the permissions on the socket directory are wrong.
Has this ever worked for you before?

Hi
Hi
Hi, You are correct, this did not work before; below I have listed the message in the error.log and the permissions settings on both directory & socket file

I am working on a Raspberry Pi 4
I want to get a python - flask web-site running on lighttpd server and therefore I started to configure fastcgi.
I as new to fastcgi, and not so familiar with the permissions management, can any detect an error in above?
Feedback is most appreciated,
Kind Regards

You posted to a topic over a year old with an unrelated problem (it never worked before).
Please read the doc HowToPythonWSGI and start a new topic on the forum. Please do not post further to this one.
