解决方法

安装：
pip install concurrent-log-handler
使用：
from logging import getLogger, INFO
from concurrent_log_handler import ConcurrentRotatingFileHandler
import os
log = getLogger()
# Use an absolute path to prevent file rotation trouble.
logfile = os.path.abspath("mylogfile.log")
# Rotate log after reaching 512K, keep 5 old copies.
rotateHandler = ConcurrentRotatingFileHandler(logfile, "a", 512*1024, 5)
log.addHandler(rotateHandler)
log.setLevel(INFO)
log.info("Here is a very exciting log message, just for you")
