I try to deploy my Django Project on a Debian OS. I use the Anaconda 3 environment for the project that I've made.
Here is the configuration of my Apache2
Alias /static /home/mydef/django_project/static
<Directory /home/mydef/django_project/static>
Require all granted
</Directory>
<Directory /home/mydef/django_project/django_project>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
WSGIScriptAlias / /home/mydef/django_project/django_project/wsgi.py
WSGIDaemonProcess django_project python-path=/home/mydef/django_project python-home=/home/mydef/venv
WSGIProcessGroup django_project
Then Reload the Apache 2 (already enable my own apache2 conf file)
Then I try to visit it localhost. But it didn't show any response (loading only). Then I check the error log then I see this error.

I have a Django application that is running on an Apache web server. However, the application throws of the error (found in the error log):
Timeout when reading response headers from daemon process 'djangoproject':
[Sat Dec 14 06:53:16.317958 2019] [wsgi:error] ... Truncated or oversized response headers received from daemon process
My application works but it's turning out to be really slow. This happens very often - especially when I keep refreshing my template. I tried looking into the error and expanding the header limit size in the Apache config file but it didn't resolve my issue.
This is my Apache config file:
Alias /static /var/myproject/myapp/static
<Directory /var/myproject/myapp/static>
Require all granted
</Directory>
Alias /media /var/myproject/myapp/media
<Directory /var/myproject/myapp/media>

</Directory>

WSGIScriptAlias / /var/myproject/myapp/myapp/wsgi.py
WSGIDaemonProcess djangoproject python-path=/var/myproject/myapp python-home=/var/myproject/myapp/venv

Does anyone know how to solve this problem?
#danny_boy, I think you will get some steps in here for WSGI error issue: Truncated or oversized response headers received from daemon process.
Some guys suggesting to add a line in httpd.conf
WSGIApplicationGroup %{GLOBAL}
Also some other guys suggestions may help you to exactly figure out your issue:

I made a django project and I tried deploying it with apache and wsgi, however I'm getting the following error in error.log:

Django 2.2.6 is only compatible with python 3, so I'm not sure what to do. I'm not married to the idea of using apache, so if you have any recommendations for other webservers, that will serve as well.
Thanks!
Problem: Followed standard setup for Django web app. I am using Ubuntu 18.04, Django 2.2.1, Python 3.7, Apache 2.4.29, mod-WSGI 4.6.7, and virtualenv to create a virtualenv. When I attempt to access my site (either IP or FQDN) I get a 504 Gateway Timeout Error
I check the Apache2 logs and am getting the following error at 1-second intervals:

python manage.py runserver works fine and I can access through either IP or FQDN via browser from other devices. There are no problems with the database or other issues (although when using FQDN instead of IP # I am getting 404 error on CSS/JS, although rest loads - but this is potentially a separate issue)
I have tried:
* Resetting up virtualenv
* Resetting up Apache2
* Different apache .conf arrangements
* I watched #Graham Dumpleton's excellent video from PyCon Au 2010 "Getting Started with Apache/mod_wsgi." and tried to implement some of his insights

UPDATE: Thanks to Graham's link below I was able to get it working. I believe I had libapache2-mod-wsgi-py3 installed via apt-get install on the system. I had also tried installing mod-wsgi via pip while Python virtual environment was active, but neither worked. I checked the mod-wsgi.so and mod-wsgi.so-python3.6 (or similarly named file indicating Python 3.6) and it looked like the mod-wsgi.so was symlinked to the python 3.6 .so file.
SOLUTION: I purged libapache2-mod-wsgi-py3 from the system and followed the installation instruction guide on https://modwsgi.readthedocs.io/en/develop/user-guides/quick-installation-guide.html per Graham's advice. I made sure to use ./configure --with-python=/path/to/virtualenv/python to make sure the right Python was being used to install mod-wsgi.
This solved the problem. Thank you #Graham Dumpleton.
I have installed django website in a new Ubuntu 17.10 server. It is based on python3. It works fine when i run the website in development mode using
python manage.py runserver
But when i tried to configure it via apache2 webserver in port 80 by adding wsgi in apache by editing default config file as shown..

but Site is not working. When I checked the apache error log to find this error...

Current thread 0x00007f906c390bc0 (most recent call first):
I am not able to find what is this encodings module. it worked fine in development mode. so python is not missing any libraries for sure.
What could be the problem with my configuration.
Instead of:
python-home=/home/usr/mygpsproject/venv/bin/
you should be using:
python-home=/home/usr/mygpsproject/venv
Review the documentation on using virtual environments. You are supposed to point to the root of the virtual environment as given by sys.prefix, not the bin directory.
http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html
Also ensure that the virtual environment is created from the same Python version that mod_wsgi was compiled for.
Finally, depending on the Linux distribution used, you also shouldn't place your code under your personal home directory as the permissions on the home directory can be such that the user that runs your code as under Apache can't access the home directory.
I am trying to setup a simple Django app using this tutorial:
https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-apache-and-mod_wsgi-on-ubuntu-14-04
My configuration is:
Ubuntu 14.04, Apache/2.4.7, libapache2-mod-wsgi-py3, Python 3.4, Django 1.86
I keep getting the following error in the apache log whenever I try to access the server using its IP:
ImportError: No module named 'encodings'
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named 'encodings'

There were no errors while setting up Django in the virtualenv.
I was finally able to solve this. As I am using Python 3.4, I needed to install libapache2-mod-wsgi-py3 earlier. This installs a precompiled version of mod-wsgi into the Apache modules folder at /usr/lib/apache2/modules.
It also installed the apache module for wsgi-express.
The modules to be loaded by Apache are controlled by configuration files in /etc/apache2/mods-enabled/
Here there are 2 files for each module. A .load and a .conf file. I saw the files wsgi.load & wsgi.conf and also wsgi-express.load & wsgi-express.conf
The .load files mention the .so module to be loaded
Both the .load files had a line beginning with:
LoadModule wsgi_module /usr/lib/apache2/modules/...
That means the wsgi_module was being loaded twice. I used to receive a warning whenever I would restart Apache 2, that mod-wsgi is already loaded so skipping. So the first thing I did was disabled mod-wsgi_express
a2dismod wsgi_express
That left only 1 mod-wsgi to be loaded. This should work.
I actually went a step further and compiled the latest mod-wsgi from source following https://www.digitalocean.com/community/tutorials/installing-mod_wsgi-on-ubuntu-12-04
The latest mod-wsgi can be found here https://github.com/GrahamDumpleton/mod_wsgi/releases
That compilation went smoothly and I got a module named mod_wsgi.so-3.4 in /usr/lib/apache2/modules
In my /etc/apache2/mods-enabled/wsgi.load I put in :
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so-3.4
After restarting Apache it worked!
