Python Cherrypy 访问日志轮转

Question

如果我希望Cherrypy的访问日志只有一个固定的大小，那么如何使用循环日志文件呢？在

我已经尝试过http://www.cherrypy.org/wiki/Logging，它似乎过时了，或者缺少信息。在

Answer 1

看http://docs.python.org/library/logging.html。在

您可能需要配置RotatingFileHandler

http://docs.python.org/library/logging.html#rotatingfilehandler

Answer 2

custom log handlers的CherryPy文档展示了这个例子。在

以下是我在我的应用程序中使用的稍作修改的版本：

import logging
from logging import handlers

def setup_logging():

    log = cherrypy.log

    # Remove the default FileHandlers if present.
    log.error_file = ""
    log.access_file = ""

    maxBytes = getattr(log, "rot_maxBytes", 10000000)
    backupCount = getattr(log, "rot_backupCount", 1000)

    # Make a new RotatingFileHandler for the error log.
    fname = getattr(log, "rot_error_file", "log\\error.log")
    h = handlers.RotatingFileHandler(fname, 'a', maxBytes, backupCount)
    h.setLevel(logging.DEBUG)
    h.setFormatter(cherrypy._cplogging.logfmt)
    log.error_log.addHandler(h)

    # Make a new RotatingFileHandler for the access log.
    fname = getattr(log, "rot_access_file", "log\\access.log")
    h = handlers.RotatingFileHandler(fname, 'a', maxBytes, backupCount)
    h.setLevel(logging.DEBUG)
    h.setFormatter(cherrypy._cplogging.logfmt)
    log.access_log.addHandler(h)

setup_logging()

Answer 3

I've already tried http://www.cherrypy.org/wiki/Logging, which seems out of date, or has information missing.

尝试添加：

import logging
import logging.handlers
import cherrypy # you might have imported this already

而不是

^{pr2}$

也许可以试试

log = cherrypy.log
