Python运维自动化之nginx配置文件对比操作示例

本文实例讲述了Python运维自动化之nginx配置文件对比操作。分享给大家供大家参考，具体如下：

文件差异对比diff.py

#!/usr/bin/env python
#
import difflib
import sys
try:
  textfile1=sys.argv[1]
  textfile2=sys.argv[2]
except exception,e:
  print "Error:"+str(2)
  print "Usge: difflib.py file1 file2"
  sys.exit()
def readfile(filename):
  try:
    fileHandle=open(filename,'rb')
    text=fileHandle.read().splitlines()
    fileHandle.close()
    return text
  except IOError as error:
    print ('read file Error:'+str(error))
    sys.exit()
if textfile1=="" or textfile2=="":
  print "usege :difflib.py file1 file2"
  sys.exit()
text1_lines=readfile(textfile1)
text2_lines=readfile(textfile2)
d = difflib.HtmlDiff()
print d.make_file(text1_lines, text2_lines)

#python diff.py nginx1.conf nginx2.conf > diff.html

利用的是difflib模块，Python2.3以上版本自带的库
