[SOLVED] Writing a mod-wsgi script on Amazon linux

Issue

I am using httpd2.4 with mod-wsgi installed on Amazon linux.

My wsgi script looks like this:

/projects/mv2/test/test.wsgi

import sys
import os

sys.path.insert(0, os.path.dirname(os.path.realpath(__file__)))

from test import *

/projects/mv2/test/test.py

from flask import Flask
app = Flask(__name__)

@app.route('/test')
def hello_world():
    return 'Hello, World!'

Apache conf file

<VirtualHost *:80>
    ServerName test-algo.com

    WSGIDaemonProcess algos_app user=mv2 group=mv2 threads=1
    WSGIScriptAlias / /projects/mv2/test/test.wsgi

    <Directory /projects/mv2/test/test>
        WSGIProcessGroup algos_app
        WSGIApplicationGroup %{GLOBAL}
        Options MultiViews FollowSymLinks
        AllowOverride all
        Require all granted

    </Directory>
</VirtualHost>

When I hit the url http://test-algo.com/test, I get a 403 response and the following the httpd error file

[authz_core:error] [pid 27555] [client 153.156.225.142:65083] AH01630: client denied by server configuration: /projects/mv2/test/test.wgi

I am not able to find what is wrong with the wsgi script.


Solution

The Directory blog should start with:

<Directory /projects/mv2/test>

You have an extra test at end of path.

That would cause the 403 error.

The WSGI script should also use:

from test import app as application

The name of the WSGI entry point is expected to be application not app as your Flask file uses.

If don't fix this you will get a different error after fixing the first.
