mod_fcgi errors with apache

[Gordon McKinnon]

Hello,

I'm upgrading from RedHat 6 to Redhat 9 and migrating a trac instance from 1.0 to 1.6.  The trac instance runs in tracd, though it throws errors for some items like login, but I can't get past 500 errors in apache.  

The error I'm getting is:

import pkg_resources: /projects/project_deploy/cgi-bin/trac.fcgi

I'm using the alternative in the fcgi script, 

os.environ['TRAC_ENV'] = '/projects/project_deploy'

I tried using my upgraded trac directory, and also tried doing a deploy and configuring that.  Selinux is running but I don't see any recent errors.  I'm running redhat 9.4, apache 2.4.57, trac 1.6, and Python 3.9.18.

Does anyone have advice?  I upgraded my apache configuration from 2.2 to 2.4 so I may have missed something obvious.  Static pages and subversion work now, though.

Thank you,

Gordon

I added ExecCGI and it's now throwing other errors (upgrade your schema, Forbidden).  So I missed an obvious apache config.

And now it is working properly.  Nothing related to trac, I just missed some apache 2.4 config changes.
