Why wont Web.py let me run a server on port 80?

Im trying to create a website with Web.py but its not letting me open a create a socket on port 80 but it works on every other port.

I have port forwarded and all that so that's not the problem.

python main.py 80

but when I do this I get the error:

http://0.0.0.0:80/
Traceback (most recent call last):
  File "main.py", line 43, in <module>
    app.run()
  File "/usr/local/lib/python2.7/dist-packages/web/application.py", line 311, in run
    return wsgi.runwsgi(self.wsgifunc(*middleware))
  File "/usr/local/lib/python2.7/dist-packages/web/wsgi.py", line 54, in runwsgi
    return httpserver.runsimple(func, validip(listget(sys.argv, 1, '')))
  File "/usr/local/lib/python2.7/dist-packages/web/httpserver.py", line 148, in runsimple
    server.start()
  File "/usr/local/lib/python2.7/dist-packages/web/wsgiserver/__init__.py", line 1753, in start
    raise socket.error(msg)
socket.error: No socket could be created

my code so far is:

import MySQLdb
import web
import hashlib as h


urls = (

'/', "index", "/register/?", "register", "/login/?", "login", "/thankyou/?", "thankyou"

)

app = web.application(urls, globals())
render = web.template.render("templates/")
db = web.database (dbn="mysql", user="root", pw="461408", db="realmd")

class index():
    def GET(self):
        return render.index()
class register():
    def GET(self):
        return render.register()
    def POST(self):
        i = web.input()
        user = h.sha1(i.username).hexdigest()
        pw = h.sha1(i.password).hexdigest()

        n = db.insert("account", username=user, password=pw)




if __name__ == '__main__':
    app.run()

Can someone help please?

Could it be the fact you're trying to launch web.py as an unprivileged user?

try:

sudo python ./bin/blah.py

I successfully start the service by using this command in port 80

sudo python index.py 80

but when I use the shortcut key （control+c） to close the service,there will be an error.

    app.run()

When it happens, I Kill All Python Processes...

killall -9 python

it's can solve the above problems, but not recommended

I ran into the same problem on my RaspberryPi. To fix I just added sudo before the command. Try: sudo python main.py 80

Visit 127.0.0.1 in a browser. There is likely already a process using port 80, and that port is supposed to be used for http, so that's probably the easiest way to see what's using it.

You possibly have something else working on port 80. Try the command netstat -ln | grep 80 to check that.

Alternatively, you can try telnet localhost 80, and if the connection is refused then that port should be clear to use.
