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.所以我想知道如何将默认端口从8890更改为80？

我已运行以下命令ipython profile create来创建个人资料。

然后编辑ipython_notebook_config.py并对其进行编辑以包含以下内容：

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.

但是，似乎没有其他东西使用端口80.Apache不会在启动时启动并被禁用。我甚至使用netstat来查看每个端口的使用情况。

$ sudo netstat -lnp

Answer 1

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

是我在流浪盒中运行ipython所做的。（打开流浪盒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]

如果端口已被占用，请查看阻止它的内容 - 在我的情况下，这是一个未正确终止的旧的ipython实例。我用这个命令把它们全部搞好了

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

Answer 2

要暂时更改端口，请通过触发以下命令从终端启动jupyter笔记本电脑服务器时指示其他端口号。

jupyter notebook --port 9999

了解更多https://jupyter.readthedocs.io/en/latest/running.html

Answer 3

有些东西已经在80上侦听，你无法将2台服务器绑定到同一个端口。使用侦听80的代理，并根据URL或地址重定向到其他服务器和IPython。也不要使用80，使用443，如果你正在运行公共服务器，它应该通过TLS来保证安全。

请注意，对于任何低端口号，您可能需要将进程权限增加到root，可能使用sudo。

Answer 4

在Jupyter中，我们可以通过两种方式在不同的端口上启动笔记本电脑。

临时端口-通过像下面的命令一样在args中提及端口，我们可以在该端口上运行Jupyter。但是，每当需要在其他端口中运行Jupyter时，都必须在命令参数中提及端口。

jupyter notebook --port 9999

永久端口配置-通过更改配置，我们可以在计算机上的其他端口上永久运行Jupyter。为此，请按照以下步骤操作。
- 在nano中打开配置文件
nano ~/.jupyter/jupyter_notebook_config.py
- 通过更改以下配置的值来更改端口
c.NotebookApp.port = 9999
- 启动笔记本
jupyter notebook

宾果!!!

Answer 5

仅供参考，在Docker容器中运行并将配置更改为使用端口80：

c.NotebookApp.port = 80

依次导致这些错误：
