python3.x - python 脚本linux 运行-PHP中文网问答

我想让一个写日志的脚本在后台运行，即使我关闭终端；
但是测试中我是用了python generate_log.py 是可以正常写入文件的，
但是当我使用了nohup python generate_log.py 日志文件一直是空
nohup python generate_log.py & 也是空的
nohup python -u generate_log.py & 也是空的
python generate_log.py & 也是空
我是用ps -ef 查看了进程是一直存在的
这是我的源码：

import time

    a = datetime.now()
    a=str(a)
    log="""{0}-POST /kibana/elasticsearch/_msearch?timeout=30000&ignore_unavailable=true&preference=1447070343481 HTTP/1.1" 200 8352 "https://app.logz.io/kibana/index.html" "Mozilla/5.0 (X11; Linux armv7l) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/45.0.2454.101 Chrome/45.0.2454.101 Safari/537.36" 0.465 0.454""".format(a)
