用来检查某个服务是否正常使用的py脚本,如果不正常的话就会杀掉重启

checkservice

import socket
import threading
import os
import subprocess

def CheckService():
        sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sk.settimeout(1)
        try:
            sk.connect(('xxx.xxx.xxx.xxx',0000))
        except Exception:
            print "serive error"
            global shadowocks
            shadowocks.kill()
            shadowocks = subprocess.Popen(["/home/xxx/xxx"])
        sk.close()
        global t
        t = threading.Timer(3.0,CheckService)
        t.start()

shadowocks = subprocess.Popen(["/home/xxx/xxx"])
t = threading.Timer(3.0,CheckService)
t.start()
