Question

我想将自己应用程序的日志文件放在正确的位置。我不确定，但我认为在unixoid系统上它是/var/log。但是权限存在问题。

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import logging, logging.handlers

_LOG_FILENAME = '/var/log/myapp.log'

log = logging.getLogger('')
fh = logging.handlers.RotatingFileHandler(_LOG_FILENAME, maxBytes=10240, backupCount=3)
log.addHandler(fh)

log.info('log message')

导致此错误：

Traceback (most recent call last):
  File "./log.py", line 8, in <module>
    fh = logging.handlers.RotatingFileHandler(_LOG_FILENAME, maxBytes=10240, backupCount=3)
  File "/usr/lib/python3.4/logging/handlers.py", line 150, in __init__
    BaseRotatingHandler.__init__(self, filename, mode, encoding, delay)
  File "/usr/lib/python3.4/logging/handlers.py", line 57, in __init__
    logging.FileHandler.__init__(self, filename, mode, encoding, delay)
  File "/usr/lib/python3.4/logging/__init__.py", line 992, in __init__
    StreamHandler.__init__(self, self._open())
  File "/usr/lib/python3.4/logging/__init__.py", line 1016, in _open
    return open(self.baseFilename, self.mode, encoding=self.encoding)
PermissionError: [Errno 13] Permission denied: '/var/log/myapp.log'

默认情况下，要将日志文件放在/ var / log中，您的应用程序必须以root身份运行。

提示：创建子目录并设置好主人

 mkdir /var/log/myapp
 chown myuser /var/log/myapp

最好的考虑

如何使用Python3中的日志包将我自己的日志文件放在正确的位置？
