    #获取当前路径

    while(1):

        if(processNum

            os.system('cd '+path)

            os.system('nohup python tt.py &')

            log_index = log_index + 1

            time.sleep(5)

    processInfo = os.popen("ps -ef|grep tt.py|grep -v grep|awk '{print $2}'").readlines()

    for pid in processInfo:

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

    

def stopParent():

    parentList = os.popen("ps -ef|grep Monitor.py|grep -v grep|awk '{print $2}'").readlines()

    for pid in parentList:

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

 

#杀掉除了自己所有的进程

def stopParent2():

    index = 0

    parentList = os.popen("ps -ef|grep Monitor.py|grep -v grep|awk '{print $2}'").readlines()

    for pid in parentList:

        index = index+1

        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
