我在启动CherryPy时遇到了一些麻烦,我无法弄清楚为什么我会一直收到这个错误。这是版本和带日志输出的相关代码。
Python 2.7.6 CherryPy 3.5.0(通过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:

答案 0 :(得分:3)
我猜Daemonizer
存在表示您实际上在询问 CherryPy 部署。
首先,cherrypy.engine.start()
不足以启动 CherryPy 。查看cherrypy.quickstart
的最小例程。我把它放在__name__ == '__main__'
条件下。它允许您直接从shell执行脚本。
其次,您不应该直接在应用程序代码中处理Daemonizer
插件(和PIDFile
,DropPrivileges
等)。有cherryd应该处理系统的东西。
您可以通过cd
运行以下代码(将static.py,cherryd -i static
放入包含目录)。它将在前台启动您的应用程序。 cherryd -d -i static
会守护您的应用。
#!/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()
