将python脚本运行过程中的报错信息写入日志文件

1、编写logger.conf文件

[loggers]
keys=root,example01

[logger_root]
level=WARNING
handlers=hand01

[logger_example01]
handlers=hand01
qualname=example01
propagate=0


###############################################
[handlers]
keys=hand01

[handler_hand01]
class=handlers.RotatingFileHandler
level=INFO
formatter=form01
args=("myapp.err", "a", 10*1024*1024, 1)


###############################################
[formatters]
keys=form01

[formatter_form01]
format=%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s
datefmt=%Y-%e-%d %H:%M:%S

2、编写测试文件mytest.py

#!/usr/bin/env python
import logging
import logging.config

logging.config.fileConfig("logger.conf")
logger = logging.getLogger("example01")

def testfun():
    print "test"

try:
    testfun(1)
except TypeError,e:
    logging.error("There is a error in this file",exc_info=1)

3、执行测试文件

[root@localhost tmp]# python mytest.py 

4、查看myapp.err文件的内容

[root@localhost tmp]# cat myapp.err 
2016-14-14 22:52:12 mytest.py[line:14] ERROR There is a error in this file
Traceback (most recent call last):
  File "mytest.py", line 12, in <module>
    testfun(1)
TypeError: testfun() takes no arguments (1 given)

可知脚本运行过程中出现的异常信息已被写入至myapp.err文件中。
