Django Python Project的Apache和mod_wsgi设置

Question

I am trying to setup my django-python project on Google Compute Engine Debian8 VM. I made few config changes in /etc/apache2/sites-available/000-default.conf & /etc/apache2/sites-available/default-ssl.conf files Then tried to restart the server. And I got following Errors. Uninstalling & reinstalling the apache2 too is not fixing this error. Any suggestions to fix this issue ?

Command:

sudo service apache2 restart

Error:

Job for apache2.service failed. See 'systemctl status apache2.service' and 'journalctl -xn' for details.

Command:

sudo systemctl status apache2.service -l

Error:

apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2)

Have you read the error ? It's clearly stated why it fails:

Cannot load /usr/lib/apache2/modules/mod_wsgi.so into server: /usr/lib/apache2/modules/mod_wsgi.so: cannot open shared object file: No such file or directory

do you have libapache2-mod-wsgi or libapache2-mod-wsgi-python3 installed? if you have access to shell you can install it with

sudo apt-get install libapache2-mod-wsgi
# or for python 3
sudo apt-get install libapache2-mod-wsgi-python3

Ran the Command to see the process running on port 80:

sudo netstat -ltnp | grep ':80'

Output:

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      24482/nginx -g daem
tcp6       0      0 :::80                   :::*                    LISTEN      24482/nginx -g daem

Running the next two commands then fixed the issue:

sudo kill -9 24482
sudo service apache2 restart

Hope it can be helpful.

Thanks,
