Python实现日志文件的自动轮转与定期清理

pip install watchdog

import logging

from logging.handlers import RotatingFileHandler

def setup_logger():

    # 创建logger对象

    logger = logging.getLogger('my_logger')

    logger.setLevel(logging.INFO)

    # 设置日志格式

    formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')

    # 使用RotatingFileHandler代替默认的FileHandler

    handler = RotatingFileHandler('app.log', maxBytes=5*1024*1024, backupCount=5)

    handler.setFormatter(formatter)

    # 将handler添加到logger

    logger.addHandler(handler)

    return logger

import os

import schedule

import time

def clean_logs():

    """删除超过一个月的日志"""

    now = time.time()

    cutoff = now - (30 * 86400)  # 30天前的时间戳

    for f in os.listdir('.'):

        if f.startswith('app.') and f.endswith('.log'):

            log_file_path = os.path.join('.', f)

            if os.path.getmtime(log_file_path) < cutoff:

                os.remove(log_file_path)

                print(f"Deleted old log: {f}")

# 每天凌晨1点执行一次清理

schedule.every().day.at("01:00").do(clean_logs)

while True:

    schedule.run_pending()

    time.sleep(1)
