I have a simple flask app that i want to be accessible from internet.
OS is debian7, and unfortunately it can't be changed.
What I did:
- downloaded and installed Python3.4 into /usr/local/opt/python3.4.3
- installed wsgi lib for py3
- installed virtualenv and created new env in my flask project folder
- installed flask together with some other packages that I need within this env
- created VirtualHost as follows:
cat /etc/apache2/sites-available/Monitor
Listen 8080
<VirtualHost *:8080>
ServerName {ip address}
ServerAdmin {my email}
WSGIScriptAlias / /var/www/Monitor/monitor.wsgi
<Directory /var/www/Monitor/Monitor/>
Order allow,deny
Allow from all
</Directory>
Alias /static /var/www/Monitor/Monitor/static
<Directory /var/www/Monitor/Monitor/static/>
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
now when i try to access the app from the internet I see these errors in error.log

From what I could find in the internet, such errors appear when trying to start flask app with python version <= 3.3, which is not my case I think (how do i check?)
here is my wsgi that starts the app
#!/usr/bin/env python3
import os
import sys
import logging
logging.basicConfig(stream=sys.stderr)
PROJECT_DIR = '/var/www/Monitor/'
sys.path.insert(0, PROJECT_DIR)
def execfile(filename):
globals = dict(__file__ = filename)
exec(open(filename).read(), globals)
activate_this = '/var/www/Monitor/Monitor/venv/bin/activate_this.py'
execfile(activate_this)
from Monitor import app as application
Any help would be very much appreciated. Any additional information will be supplied if necessary.
Default Python3 on Debian 7 is 3.2.3, libapache2-mod-wsgi is in version 3.3.
You Apache run Your app with default Python because mod-wsgi has to be compiled against one and only one python version (in this case python 3.3).
mod-wsgi 3.3
If You want to run only one app (or many apps) with Python 3.4, try to recompile mod-wsgi with python 3.4
mod-wsgi 4.1.x or newer
This newer version of mod_wsgi provides a way of installing mod_wsgi against multiple Python versions and running up an Apache instance for each using a provided script. The script takes over all the setup of the Apache configuration so you do not need to worry about it.
https://pypi.python.org/pypi/mod_wsgi
old answer
To change Python version, set in Apache conf:
WSGIPythonHome /usr/local/opt/python3.4.3/
WSGIPythonPath /var/www/Monitor:/var/www/Monitor/Monitor/venv/lib/python3.4/site-packages:/usr/local/opt/python3.4.3/lib/site-packages

I'm trying to run a simple Flask web app that displays a pygal graph. When I run it with the python development server, the application runs fine. However, when I try to run it in apache2, I get the following error:

Here are some details about my environment:
Ubuntu 20.04.1 LTS
Apache/2.4.41 (Ubuntu)
Python 3.8.5 (installed in a virtual environment)
Any thoughts would be greatly appreciated!
It appears that the python interpreter is compiled into the mod_wsgi.so file. An old version, that included python2, was being pointed to by Apache. To fix it I did the following:
Removed the old version of mod_wsgi by doing sudo apt-get remove libapache2-mod-wsgi
modified /etc/apache2/mods-available/mod_wsgi.load to point to the library (.so) file in my virtual environment. The contents of mod_wsgi looked like this:
LoadModule wsgi_module /var/www/FlaskApp/FlaskApp/venv/lib/python3.8/site-packages/mod_wsgi/server/mod_wsgi-py38.cpython-38-x86_64-linux-gnu.so
I suspect that modifying it here points all Apache virtual hosts to this python virtual environment, which isn't really ideal. It would be better if each Apache virtual host pointed to its own python environment.
Modified my wsgi file to work with the new version of python. Here are the contents:
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/FlaskApp/")
sys.path.insert(0,"/var/www/FlaskApp/FlaskApp/venv/lib/python3.8/site-packages/")
from FlaskApp import app as application
application.secret_key = 'secret key stuff'
Changed the local imports in my __init__.py file to be preceeded by a dot(.)
Following these changes the site is now working as expected.
I am getting a weird error while trying to run my Django site under Apache using mod_wsgi. I have been working on this for hours to no avail.
FYI: I am also using Mezzanine.

You may use a version of Django that supports Python 2.6 but make sure it also supports Mezzanine
OR
Update your Python installation to 2.7
I cannot, for the life of me, find a simple way to configure a (Linode Debian 6) server correctly with Django 1.8, Python 2.7.3, and virtualenv. Here's the steps I took:
mkvirtualenv --python=/usr/bin/python2.7 curator
This creates a VirtualEnv for me under /srv/ve/.virtualenvs/curator
Now I run:
pip install django
And Django 1.8 is successfully installed. Then, I switch to /srv/www/curator and run:
django-admin startproject cmscore
I then follow the Django Apache mod_wsgi instructions and end up with an Apache conf file under my sites-available directory looking like this:
<VirtualHost *:80>
ServerName cms.example.com
ServerAlias cms.example.com cms.example2.com
ServerAdmin errors#example.com
DocumentRoot /srv/www/curator/public_html
WSGIDaemonProcess cms.example.com python-path=/srv/ve/.virtualenvs/curator/bin/python:/srv/ve/.virtualenvs/curator/lib/python2.7/site-packages

The Django docs mention an WSGIPythonPath directive, but I get an error that WSGIPythonPath cannot occur within <VirtualHost> section when I use this.
With this configuration I get a 500 error (well obviously, there's a lot of settings I haven't added yet for example) but not one that I would expect. I get this (IPs blanked by me):

So, this appears to be an error which occurs when Django 1.8 is being using by an earlier version of Python than 2.7. To debug, I threw this into the top of my wsgi.py file:
import sys
activate_this = '/srv/ve/.virtualenvs/curator/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
sys.stderr.write(sys.version)
And in my Apache error log, I see:
2.6.6 (r266:84292, Dec 27 2010, 00:18:12)
I've tried every trick that I can think of (tricks that worked with existing virtualenvs of Django 1.6 and Python 2.7 on the exact same server!) including shebangs pointing to the correct Python install in my manage.py file, but I cannot find any way to get this to work.
I know I'm missing something really obvious here, but I am blind to it, can anyone help?
I have a django (1.7) app that works pretty well on a Centos7 server. Now i moving to production server RHEL 6 and still have some issues.
The problem is the mod_wsgi.
The server config:
RHEL6
Apache 2.2
Django 1.7
Python 2.6

I thought that a problem could be that mod_wsgi seems compiled with lib64, so I changed the python path on the flweb.conf to lib64 but it didn't worked
EDIT:
I realize the server has python 2.7 in /user/local/lib and that is the python version where django is installed. I changed the path in the conf file, but now I guess I need to rebuild the mod_wsgi
EDIT2:
Trying to rebuild mod_wsgi, have this problem
/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC
according to https://code.google.com/p/modwsgi/wiki/InstallationIssues is a conflict between python that was compiled to 32 bit and mod_wsgi to 64
I'm getting this in my error logs:
ImportError: No module named flask
It looks exactly like in Django + mod_wsgi + apache: ImportError at / No module named djproj.urls, but I tried that solution, and it doesn't seem to work... I am correctly inserting the app home and parent folder into the system path, but this error is still coming up.
Navigating to my page still brings up the 500 page.
More information: I'm using Amazon EC2 free tier, with Apache in the form of httpd. Everything is installed correctly, I'm pretty sure...
Here's my stuff (app name badassery and app home folder name hatemail - I change my mind a lot):

Yes, I am doing "if name == 'main': app.run()".
How can I fix this problem?
If you're deploying a virtualenv, you'll have to make sure to activate it first. You should update your wsgi file like this (updating the values to match your environment):
activate_this = '/path/to/virtualenv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this)
import sys
sys.path.insert(0, '/path/to/flask/appname')
sys.path.insert(0,'/home/ec2-user/hatemail')
sys.path.insert(1,'/home/ec2-user')
from badassery import app as application
If you aren't deploying a virtualenv, you probably just need to make sure that Flask is installed on your system. If you've already installed setuptools you can just:
easy_install flask
If you have any problems with importing when using wsgi_mod, make sure you try explicitly pointing to the import files that are causing problems:
sys.path.append('/home/foo/www/Forms')
then do your import!
