wsgi module integration with python in virtual environment

Make sure python is installed with shareable on

Download python source

cd Python-3.5.0

./configure –enable-shared             –prefix=/usr/local             LDFLAGS=”-Wl,–rpath=/usr/local/lib”

Build wsgi using virtualenv python

Download wsgi source

cd mod_wsgi-4.6.2

./configure –with-python=/home/rbaisak/pyeztask1/bin/python3.5

sudo make install

And finally in wsgi.cnf file

WSGIPythonHome /home/rbaisak/pyeztask1/

WSGIPythonPath /home/rbaisak/pyeztask1/bin:/home/rbaisak/pyeztask1/lib/python3.5/

# create new app

WSGIScriptAlias /pyeztaskweb/ /var/www/pyeztaskweb/

in httpd.cnf, you can specify directory

<Directory “/var/www/pyeztaskweb”>

   Order allow,deny

   Allow from all


Start wsgi with own daemon process

If you want to start wsgi with own daemon process and virtual environment, then please make following changes in yours config file. I prefer to make changes in httpd.cnf file

WSGIDaemonProcess pyeztaskweb(project name) user={different than root who can access your virtual env} group={different than root who can access your virtual env} processes=2 threads=25 python-path=/var/www/pyeztaskweb/{your app path} python-home={virtual env home}
WSGIProcessGroup pyeztaskweb
WSGISocketPrefix run/wsgi //This is the location of socket file to be created

WSGIScriptAlias /pyeztaskweb /var/www/pyeztaskweb/ process-group=pyeztaskweb application-group=%{GLOBAL}
WSGIScriptAlias /summarizer /var/www/pyeztaskweb/ process-group=pyeztaskweb application-group=%{GLOBAL}
WSGIPythonPath {refer above}

<Directory “/var/www/pyeztaskweb”>
Order allow,deny
Allow from all
