Invalid command WSGIDaemonProcess Deploy Django application on CentOS 6.7

make sure you have wsgi package installed, by running

sudo a2enmod wsgi

if its not installed, execute below commands to install

for python2

sudo apt-get install python-pip apache2 libapache2-mod-wsgi

for python3

sudo apt-get install python3-pip apache2 libapache2-mod-wsgi-py3

The mod_wsgi module should be enabled for Apache. Make sure you have symlinks setup in /etc/apache2/mods-enabled/ pointing to wsgi.conf and wsgi.load in /etc/apache2/mods-available/.

On a side note, check out the latest generation of mod_wsgi, it provides a convenient way to launch wsgi applications using a simple tool mod_wsgi-express (without the hassle of setting up an httpd configuration).

sudo apt-get remove libapache2-mod-wsgi

sudo apt-get remove libapache2-mod-wsgi-py3

II. Use pip to install mod_wsgi

pip install mod_wsgi

If it is already installed, update it:

pip uninstall mod_wsgi
pip install mod_wsgi

sudo nano /etc/apache2/mods-available/wsgi.load

remove any lines of wsgi.load And past the output from IV

VI. Ensure mod_wsgi is enabled:

sudo a2enmod wsgi

VII. Restart your apache service

systemctl reload apache2
