SELinux config for Django, Apache, MariaDB, Fedora38 stack

Ok, I'm coming here after properly watching Thomas Cameron's lecture on SELinux and reading some other resources. https://youtu.be/_WOKRaM-HI4

I'm running Fedora 38 workstation inside a Vmware Workstation Pro (v17), with the rest of my stack being Apache, MariaDB, Python.

I have Django up and running on localhost:8000, I followed the configuration for mod-wsgi, Apache, Django properly. I have a virtualhost file to run my Django app on localhost:80 as well.

But I kept getting 500 internal server error. Turns out its a SELinux issue, since I did setenforce 0, and everything works fine.

Now I'm trying to troubleshoot whatever is making SELinux upset, so that I can turn it back on enforcing again. Its a local test server.

Please bear in mind that Fedora Documentation (new as well as the wiki) is still lacking significantly on this topic. So I couldn't get much over there. Nor there is anything related to SELinux on Django documentation.

I have setroubleshoot & setroubleshoot-server installed. Haven't been able to pinpoint the issue so far. I would appreciate if anyone can help me find what is causing the issue.

Hi @SomeAB 

What do you see in the logs when the error occurs?

Could you run "ausearch -i -m AVC -ts recent" when you get the error and paste the results here?

Have you tried to run the command below?

"setsebool -P httpd_can_network_connect 1"

Please run it and them restart your application.

If it doesn't work, please share the new logs with us again.

Hi @SomeAB !

Have you tried the suggestions from your logs : 

Chetan_Tiwary__0-1687780944666.png

Try these : #semanage fcontext -a -t httpd_sys_rw_content_t 'error_log'

                 #restorecon -v 'error_log'

                 #setsebool -P httpd_unified 1

Then restart the httpd service. 

    If you continue to experience SELinux denials after trying these solutions, you can generate a local policy module using audit2allow to allow the specific access something lke this : ausearch -c 'httpd' --raw | audit2allow -M my-httpd ( but please be cautious in applying these solutions ).
