        s = 'python %s' % (__file__)
        os.system(s)
　　　　 os._exit(123)



ps -aux | grep python | grep -v grep |cut -c 9-15 | xargs kill -9

except Exception as e:
    s = '%s%s%s' % ('初始数据，查询数据库异常，无限次重启该脚本', e, time.strftime('%Y%m%d %H:%M:%S', time.localtime(time.time())))
    print(s)
    logging.warning(s)
    cmd = 'python %s' % (__file__)
    os.system(cmd)
