Debian系统Python日志如何配置与管理

import logging

# 创建一个日志记录器
logger = logging.getLogger('my_logger')
logger.setLevel(logging.DEBUG)

# 创建一个文件处理器，将日志写入到文件中
file_handler = logging.FileHandler('my_app.log')
file_handler.setLevel(logging.DEBUG)

# 创建一个控制台处理器，将日志输出到控制台
console_handler = logging.StreamHandler()
console_handler.setLevel(logging.INFO)

# 定义日志格式
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

# 将格式化程序添加到处理器
file_handler.setFormatter(formatter)
console_handler.setFormatter(formatter)

# 将处理器添加到日志记录器
logger.addHandler(file_handler)
logger.addHandler(console_handler)

# 使用日志记录器记录消息
logger.debug('This is a debug message')
logger.info('This is an info message')
logger.warning('This is a warning message')
logger.error('This is an error message')
logger.critical('This is a critical message')

from loguru import logger

# 零配置日志输出
logger.debug("调试信息")  # 默认不显示
logger.info("服务启动成功")  # 绿色输出
logger.warning("内存占用超过70%")  # 黄色警告
logger.error("数据库连接失败")  # 红色错误

# 文件日志与自动轮换
logger.add("app_{time}.log", rotation="100 MB", retention="7 days", compression="zip")

# 异常自动捕获
@logger.catch
def risky_operation():
    return 1 / 0

risky_operation()  # 错误详情自动写入日志

import logging
from dotenv import load_dotenv
import os

load_dotenv()

logger = logging.getLogger()

if os.getenv("DEBUG") == "true":
    # 测试环境
    logger.setLevel(logging.DEBUG)
else:
    # 生产环境
    logger.setLevel(logging.INFO)

# 其他日志配置...
