CherryPy无法启动 [英] CherryPy won't start

问题描述

我在启动CherryPy时遇到了一些麻烦，我不知道为什么我总是收到此错误.这是带有日志输出的版本和相关代码.

I'm having some trouble starting CherryPy and I can't figure out why I keep getting this error. Here's the versions and the related code with log output.

Python 2.7.6CherryPy 3.5.0(通过PIP)

Python 2.7.6 CherryPy 3.5.0 (via PIP)

CURRENT_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_DIR = os.path.join(CURRENT_DIR, "static")
CONFIG = {
    '/static': {
        'tools.staticdir.on': True,
        'tools.staticdir.dir': STATIC_DIR
    }
}

Daemonizer(cherrypy.engine).subscribe()                         # When we start, do it as a daemon process
cherrypy.config.update({'server.socket_host': '127.0.0.1','server.socket_port': 8080,'log.error_file': 'site.log'})       # Listen on all local IPs (default is 8080)
cherrypy.tree.mount(MyWebServer(), '/', config=CONFIG)          # Mount the app on the root
cherrypy.engine.start()

这是日志输出:

推荐答案

我猜想 Daemonizer 的存在表明您实际上是在问有关 CherryPy 部署的问题.

I guess Daemonizer presence indicates you're actually asking about CherryPy deployment.

首先， cherrypy.engine.start()不足以启动 CherryPy .看一下 cherrypy.quickstart 的最小例程.我将其置于 __ name__ =='__main __'条件下.它使您可以直接从Shell执行脚本.

First, cherrypy.engine.start() is not enough to start CherryPy. Take a look at cherrypy.quickstart for the minimal routine. I put it under __name__ == '__main__' condition. It allows you to directly execute the script from shell.

第二，您不应该直接在应用程序代码中处理 Daemonizer 插件(以及 PIDFile ， DropPrivileges 等).有 cherryd 应该处理系统内容.

Second, you shouldn't probably deal with Daemonizer plugin (and PIDFile, DropPrivileges, etc) directly in your application code. There's cherryd which should deal with system stuff.

您可以通过 cherryd -i static 运行以下代码(将static.py， cd 放入包含的目录).它将在前台启动您的应用程序. cherryd -d -i static 将守护您的应用程序.

You can run the code below (put in static.py, cd to the containing directory) by cherryd -i static. It will start your app in foreground. cherryd -d -i static will daemonize your app.

#!/usr/bin/env python
# -*- coding: utf-8 -*-


import os

import cherrypy


path   = os.path.abspath(os.path.dirname(__file__))
config = {
  'global' : {
    'server.socket_host' : '127.0.0.1',
    'server.socket_port' : 8080,
    'server.thread_pool' : 4
  },
  '/static' : {
    'tools.staticdir.on'  : True,
    'tools.staticdir.dir' : os.path.join(path, 'static')
  }
}

class App:

  @cherrypy.expose
  def index(self):
    return 'Your dynamic stuff'


cherrypy.tree.mount(App(), '/', config)


if __name__ == '__main__':
  cherrypy.engine.signals.subscribe()
  cherrypy.engine.start()
  cherrypy.engine.block()

我写了完整的 CherryPy 部署教程， cherrypy-webapp-skeleton，几年前.看一看是否需要完整的图片.

I wrote a complete CherryPy deployment tutorial, cherrypy-webapp-skeleton, a couple of years ago. Take a look if you need a complete picture.
