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)
