Python实现根据指定端口探测服务器/模块部署的方法,python部署


本文实例讲述了Python实现根据指定端口探测服务器/模块部署的方法,非常具有实用价值。分享给大家供大家参考借鉴。

有些时候,在维护过程中,服务器数量非常多。应用模块部署在不同服务器上。有时维护人员做了模块迁移,而未及时同步至手册中。查找比较困难。于是,产生Python根据应用端口进行探测,获取模块部署。

设想非常简单:通过简单的tcp链接,如果能够成功的建立,立即断开,防止影响业务。表示模块在某服务器上有部署。

具体功能代码如下:

#!/bin/env python
#
import socket
import time
from threading import Thread

hostList=["10.10.126.170","10.10.126.173","10.10.126.177","10.10.126.170","10.10.126.173","10.10.126.177"]
onLine=[]
offLine=[]
gathered=[]
hostDict={"onLine":[],"offLine":[]}
class detect(Thread):
 def __init__(self,ip, port=22):
 Thread.__init__(self)
 self.ip=ip
 self.port=port
 def run(self):
 address=(self.ip,self.port)
 sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 try:
  sock.connect(address)
  buff=sock.recv(1024)
  if(len(buff)):
  print("detect Host %s Online" % self.ip)
  onLine.append(self.ip)
 except:
  print("detect Host %s OffLine" % self.ip)
  offLine.append(self.ip)
 sock.close

def sigle_detect(ip):
 p=detect(ip)
 p.start()
 p.join(60)

def multi_detect(host):
 T_thread=[]
 for ip in set(host):
 t=detect(ip)
 t.name=ip
 t.start()
 T_thread.append(t)
 for t in T_thread:
 t.join(15)
 
def filter_gather(hlist):
 gather=[]
 for t in set(hlist):
 gather.append(t)
 return gather

def mak_hostList_byip3(iplist):
 global hostList
 hostList=[]
 for ip in set(iplist):
 tmp=ip.split('.')
 if(len(tmp)==3):
  for i in range(2,254):
  hostList.append('%s.%d' % (ip, i))
 elif(len(tmp)==4):
  hostList.append(ip)
 else:
  continue
 return hostList
def update_hostDict(onLine, offLine):
 hostDict["onLine"]=onLine
 hostDict["offLine"]=offLine

def make_pickle_fileName():
 import time
 fileName=""
 for s in time.localtime()[:5]:
 fileName=fileName+str(s)
 fileName="Host_%s.pkl" % fileName
 return fileName

def save_gathered(fileName, hostDict):
 import pickle
 F=open(fileName,'wb')
 pickle.dump(hostDict,F)
 F.close()
def recovery_gathered(fileName, keyList):
 import pickle
 try:
 F=open(fileName,'rb')
 E=pickle.load(F)
 keyList.append(E)
 except:
 F.close()
 return
 while E:
 try:
  E=pickle.load(F)
  keyList.append(E)
 except:
  F.close()
  break

if __name__=='__main__':
 sigle_detect(hostList[0])
 #---------------
 mak_hostList_byip3(hostList)
 multi_detect(hostList)
 onLine=filter_gather(onLine)
 print(onLine)
 offLine=filter_gather(offLine)
 print(offLine)
 gathered=onLine+offLine
 print(gathered)
 update_hostDict(onLine, offLine)
 print(hostDict)
 fN=make_pickle_fileName()
 save_gathered(fN,hostDict)
 keyList=[]
 recovery_gathered(fN,keyList)
 print(keyList)

希望本文讲述的方法对大家的Python程序设计有所帮助。

怎用 python(25或其它版本均可)实现图形界面,并向指定IP地址的指定端口发送数据包?回答注明版本

可以使用pygtk来实现图形界面,可以在网上找一些教程。

向指定端口发送数据包,使用socket内置库。下面有一个简单的demo以供参考:
server端:
import sockets = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)s.bind(("", 8081))while True: # Receive up to 1,024 bytes in a datagram data, addr = s.recvfrom(1024) print "Received:", data, "from", addrclient端:
import sockets = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)port = 8081host = "localhost"while True: msg = raw_input() s.sendto(msg, (host, port))
望采纳,谢谢支持!
