python + nginx internal server error

Question

So I've setup my server following this tutorial: http://jronnholm.sysio.se/setup-nginx-and-uwsgi-with-python3-on-ubuntu-14-04/

See: nginx + uwsgi + python3 configuration not working

I managed to get it to work by switching /etc/nginx/sites-available/default with /etc/nginx/sites-available/pythonapp and change the sitename to _ .

My /etc/nginx/sites-available/default :

server {
    server_name _;
    error_log  /var/log/nginx/pythonapp.error.log;
    access_log         /var/log/nginx/pythonapp.access.log;
    root /vagrant/site/python/pythonapp;
    location / {
        uwsgi_pass unix:/var/run/uwsgi/app/pythonapp/socket;
        include uwsgi_params;
    }
}

But then when I change the content of webpage.py to this:

print "Content-type: text/html\n\n"
print("lololol");

It ends up returning internal server error when I go to http://localhost:8080 .

What did I do wrong?

Answer 1

The Python code of your webpage.py is invalid. Try running it directly from the command line: python3 webpage.py will show you what is wrong.

Change your webpage.py to:

print("Content-type: text/html\n\n")
print("lololol")

The print statement has been replaced with a print() function, with keyword arguments to replace most of the special syntax of the old print statement ( PEP 3105 ).

Note I've removed the semicolon from the second line because it is not doing anything in your example. Python does not require semi-colons to terminate statements. Semicolons can be used to delimit statements if you wish to put multiple statements on the same line.
