Greetings,
This is what I've been struggling with for a while now.
I was wondering maybe somebody has experience with this.
So I have php 8.1.23 and nginx 1.24.0 installed from ports. Then I use php-fpm as fastcgi service to communicate with nginx.
Everything works perfectly, but errors reporting, which drives me crazy.
What I'm trying to achieve is I want to combine PHP and nginx errors in a single log file. So, instead of php-fpm using separate log files (or syslogd) I want it to send logs back to nginx so nginx can store PHP error logs within nginx error log files.
I saw some examples online, they look something like this:
1. An example of PHP code that triggers an error
2. Nginx's error log file
I did the following configuration for nginx and php-fpm, it looks like this is what people use in general to achieve my goal.
This is not working for me.
At the beginning of my journey, I was confused about how nginx actually gets this information and thought it magically happens through STDERR descriptor from php-fpm to nginx, but then I did some digging into the FastCGI protocol, and it looks like backend (php-fpm) actually can send this information using FCGI_STDERR record type.
After the finding, I started to dump traffic between nginx and php-fpm, so I discovered that php-fpm is not sending FCGI_STDERR back to nginx when an error on the PHP side happens.
I checked docs of php-fpm configuration a couple of times and haven't found how to allow/force send this FCGI_STDERR back to nginx explicitly.
At this point, I'm completely lost.
This is probably not the best place to ask this kind of question, but I was wondering if this is somehow related to how php configures/complies from ports.
Will appreciate any help
