port - 更改 iPython 笔记本服务器/Jupyter 的默认端口

Question

我正在尝试在防火墙后面的机器上运行 ipython notebook/jupyter 服务器。唯一打开的端口是端口 80。所以想知道如何将默认端口从 8890 更改为 80？

我已经运行了以下命令 ipython profile create创建配置文件。

然后编辑ipython_notebook_config.py并编辑它以包含以下内容:

c = get_config()
c.NotebookApp.port = 80

当我尝试运行 python notebook 时。我收到以下错误:
ERROR: the notebook server could not be started because no available port could be found.
然而，似乎没有其他东西在使用端口 80。Apache 不会在启动时启动并被禁用。我什至使用 netstat 来查看每个端口的使用情况。

$ sudo netstat -lnp

Answer 1

jupyter notebook --ip=0.0.0.0 --port=80 or
ipython notebook --ip=0.0.0.0 --port=80

是我在我的流浪箱中运行 ipython 所做的。 (打开 vagrant box 上的端口以在我的主机 mac 上访问它)

usage: ipython [-h] [--certfile NOTEBOOKAPP.CERTFILE] [--ip NOTEBOOKAPP.IP]
               [--pylab [NOTEBOOKAPP.PYLAB]]
               [--log-level NOTEBOOKAPP.LOG_LEVEL]
               [--port-retries NOTEBOOKAPP.PORT_RETRIES]
               [--notebook-dir NOTEBOOKAPP.NOTEBOOK_DIR]
               [--config NOTEBOOKAPP.CONFIG_FILE]
               [--keyfile NOTEBOOKAPP.KEYFILE] [--port NOTEBOOKAPP.PORT]
               [--transport KERNELMANAGER.TRANSPORT]
               [--browser NOTEBOOKAPP.BROWSER] [--script] [-y] [--no-browser]
               [--debug] [--no-mathjax] [--no-script] [--generate-config]

如果端口已经被占用，看看是什么阻塞了它——在我的情况下，它是一个没有正确终止的旧 ipython 实例。我用这个命令杀死了他们

ps auxww | grep 'ipython' | awk '{print $2}' | xargs sudo kill -9
