if(index

os.kill(int(pid),signal.SIGKILL)

def stopAll():

stopChicd()

stopParent()

try:

fun = sys.argv[1]

except Exception:

fun = ''

if(fun == 'start'):

start()

if(fun == 'stop'):

stopAll()

if(fun == 'restart'):

stopChicd()

stopParent2()

time.sleep(1)

start()

调用的时候 python Monitor.py start|stop|restart即可
