Here’s /home/blakeh/test.py, which doesn’t really do anything but illustrate the problem with minimal code:
#!/usr/local/bin/python3
import xmlrpc.client
if __name__ == "__main__":
client = xmlrpc.client.ServerProxy('http://localhost:8010')
client.foo()
If I run this directly as the apache user, there’s no permission problem with making the RPC “foo” call. It only occurs if I run it through apache. I’m using python 3.5.2.
In an apache .conf file I have this:
ScriptAlias /test "/home/blakeh/test.py"
If I run this curl command:
curl -gix "" http://localhost/test
… I get an internal server error, with this appended to /var/log/httpd/error_log:

What could explain the difference in behavior? Thanks!

Answer
Velkan’s suggestion to check selinux worked. I could get this working by putting it in permissive mode with “setenforce 0”. Adding this as an “answer” so I can mark it as solved.
