I'm trying to debug a problem with a file upload strategy and don't know whether there's an issue with directory permissions / ownership or the scripts. ... I've tried both PHP and JavaScript and can't seem to get enough information to track down what's happening, despite tail -f on both the error and access logs for the domain.

NOTE: I've tried to increase the LogLevel on the php module - I'm running 7 - but I can't seem to find the module name.

This is on Fedora 31 /32 and there's a file /etc/httpd/conf.d/php.conf that says it's looking for mod_php7, and a comment that there's no mod_php in the default configuration. However, I KNOW php is running. . . NEITHER mod_php nor mod_php7 are acceptable in LogLevel - perhaps it's not loaded until / when needed?!

So, I enabled debug LogLevel on the directory instead. Lots of data, no idea why it's not working. ...Trying to increase the LogLevel, but this seems to be headed the wrong way - too much noise! And I don't ever see the data passed.

Update on Logging

I increased the LogLevel only for the directory that kicks off the upload to trace5. I got a lot more data and still nothing on either file access or why the upload fails.

...Do browser side things like Web Consoles (Firefox is what I'm using) have anything to share here? I would think not, but I'm a novice at this!

  • Start with installing a php script with nothing but "phpinfo();". It'll show you (when you browse to that page) a lot of information concerning your configuration.

  • @MichaelHampton I installed it the usual way on Fedora Server - by installing Fedora Server. It comes with. I know it's being called because of the browser's Web Console contents... What I can't see are when it tries to touch disk space.... I'm about to update the comment to include more about my trace efforts...

  • I just installed Fedora Server. It doesn't install either Apache or PHP. How did you manage to get them?

  • @MichaelHampton Hmmm... That confuses me! Well, I can tell you that I use all the standard Fedora tools like DNF and sometimes yum, and, more rarely these days, rpm. I know for sure I didn't explicitly install these this time, which, well, IDK what to say about that but I'll be glad to share the installed package list above! ... Right now, family member with issues, so it'll take another hour or so to do.

A few ideas.

Turn up the debug logging in apache.

Run strace against the process.

  • I've used strace many times but don't have a clue how I run it against an image apache starts during the server / web browser exchange..
