1. 模块安装
pip install logging
pip install pyyaml
2. 使用
2.1 创建配置文件
创建名为 logging.config.yaml 文件, 内容如下：
version: 1
disable_existing_loggers: False
formatters:
simple:
format: "%(asctime)s - %(name)s - %(levelname)s - %(message)s"
handlers:
console:
class: logging.StreamHandler
level: DEBUG
formatter: simple
stream: ext://sys.stdout
info_file_handler:
class: logging.handlers.RotatingFileHandler
level: INFO
formatter: simple
filename: info.log
maxBytes: 10485760
backupCount: 20
encoding: utf8
error_file_handler:
class: logging.handlers.RotatingFileHandler
level: ERROR
formatter: simple
filename: errors.log
maxBytes: 10485760
backupCount: 20
encoding: utf8
loggers:
my_module:
level: ERROR
handlers: [info_file_handler]
propagate: no
root:
level: INFO
handlers: [console,info_file_handler,error_file_handler]
logging 的配置：https://docs.python.org/2/library/logging.config.html
2.2 在Python脚本中使用
# !/usr/bin/env python
# -- coding: utf-8 --
# @Time : 2018/4/27 20:16
# @Author : Baimoc
import logging.config
import yaml
# 日志文件配置
def get_logger():
log_conf = 'logging.config.yaml'
with file(log_conf, 'rt') as f:
config = yaml.safe_load(f.read())
logging.config.dictConfig(config)
return logging.getLogger()
if __name__ == '__main__':
logger = get_logger()
logger.info(">>> Check Program paths")
logger.error(soft_name + " program not found, please edit the configuration script.")
