I am trying to deploy a flask application in the same way I do when using python2.7, but in this case I am using python3 and an error is returned in wsgi. Below follows the first line of apache2 traceback.

[Thu Dec 06 23:01:04.823744 2018] [wsgi:error] [pid 21968:tid 139980181575424] [client 189.127.245.17:55892] mod_wsgi (pid=21968): Target WSGI script '/var/www/FlaskApp/flaskapp.wsgi' cannot be loaded as Python module.

I installed the required Packages correctly, including the libapache2-mod-wsgi-py3 who I believe is right for Python3.

Flaskapp.conf

<VirtualHost *:80>
  ServerName ip-do-servidor
  ServerAdmin admin-do-servidor
  WSGIScriptAlias / /var/www/FlaskApp/flaskapp.wsgi
  <Directory /var/www/FlaskApp/FlaskApp/>
      Order allow,deny
      Allow from all
  </Directory>
  Alias /static /var/www/FlaskApp/FlaskApp/static
  <Directory /var/www/FlaskApp/FlaskApp/static/>
      Order allow,deny
      Allow from all
  </Directory>
  ErrorLog ${APACHE_LOG_DIR}/error.log
  LogLevel warn
  CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

flaskapp.wsgi

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0, "/var/www/FlaskApp/")

from FlaskApp import app as application
application.secret_key = 'super_secret_key'
python python-3.x deploy flask apache2

  • Check which standard version of Python on the system, it might be loading version 2.7 by default instead of 3.x.

  • You are using the correct version, python3.6

  • For Python3.6+ you need to use mod_wsgi_python3.6.so. If you need help setting up take a look therein

I was able to fix, the error was in my application and not in wsgi itself, I was able to visualize the correct error after going down to the last line of apache error.log.
