Question

我正在尝试使用Web.py创建一个网站，但它不允许我在端口80上打开创建套接字，但它适用于其他所有端口。

我已将端口转发，所有这些都不是问题。

python main.py 80

但是当我这样做时，我收到错误：

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

到目前为止，我的代码是：

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()

有人可以帮忙吗？

Answer 1

您可能在端口80上有其他工作。尝试使用命令netstat -ln | grep 80进行检查。

或者，您可以尝试telnet localhost 80，如果连接被拒绝，则应该清楚使用该端口。

Answer 2

我在端口80

中使用此命令成功启动了该服务

sudo python index.py 80

但是当我使用快捷键（control + c）关闭服务时，会出现错误。

当它发生时，我会杀死所有Python进程......

killall -9 python

它可以解决上述问题，但不推荐

Answer 3

在浏览器中访问127.0.0.1。可能已经有一个使用端口80的进程，并且该端口应该用于http，因此这可能是查看使用它的最简单方法。

Answer 4

我在RaspberryPi上遇到了同样的问题。为了解决这个问题，我在命令之前添加了sudo。试试：sudo python main.py 80

Answer 5

您是否尝试以非特权用户身份启动web.py？

尝试：

sudo python ./bin/blah.py

为什么Web.py不允许我在端口80上运行服务器？
