本文提供了一种方法,该程序可实现抓取服务器的日志文件到本地,根据该程序可自行扩展对日志文件的自动化分析。常用于数据挖掘、生产维护等

复制代码 代码如下:

import os
import sys
import ftplib
import socket

##################################################################
# sign in the ftp server and download the log file.
# 登陆生产服务器下载日志
#################################################################
def getServerLog(dir,fileName,host,userName,password):
 if os.path.exists(fileName):
 print '****the file '+ fileName +' has already exist! The file will be over writed'
 #connect
 try:
 f=ftplib.FTP(host)
 except (socket.error,socket.gaierror),e:
 print '----ERROR:cannot reach '+host
 print e
 return False
 #login
 try:
 f.login(user=userName,passwd=password)
 except ftplib.error_perm ,e:
 print '----ERROR:cannot login to server '+host
 print e
 f.quit()
 return False
 print '****Logged in as ' + userName + ' to server ' +host
 #change folder
 try:
 f.cwd(dir)
 except ftplib.error_perm,e:
 print '----ERROR:cannot CD to %s on %s' % (dir,host)
 print e
 f.quit()
 return False
 print '**** changed to %s folder on %s' % (dir,host)
 #get file
 try:
 f.retrbinary('RETR %s' % fileName,open(fileName,'wb').write)
 except ftplib.error_perm,e:
 print '----ERROR:cannot read file %s on %s' % (fileName,host)
 print e
 os.unlink(fileName)
 return False
 else:
 print '****Downloaded '+ fileName +' from '+ host +' to '+os.getcwd()
 f.quit()
 return True

if __name__ == "__main__":
 getServerLog("/userhome/root/other/temp","a.out","10.10.10.10","root","password")
 print '****done'


运行:python getServerLog.py
