更改 iPython 笔记本服务器/Jupyter 的默认端口
Changing the default port for iPython notebook server / Jupyter
我正在尝试 运行 ipython notebook / jupyter 服务器在防火墙后面的机器上。唯一开放的端口是端口 80。所以想知道如何将默认端口从 8890 更改为 80？
我有 运行 以下命令 ipython profile create 来创建配置文件。
然后编辑 ipython_notebook_config.py 并将其编辑为包含以下内容：
c = get_config()
c.NotebookApp.port = 80
当我尝试运行 python笔记本。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 查看每个端口的使用情况。
$ sudo netstat -lnp

某些东西已经在 80 上侦听，您不能将 2 个服务器绑定到同一个端口。使用侦听 80 的代理，并根据 URL 或地址重定向到您的其他服务器和 IPython。也不要使用 80，使用 443，如果你是 运行 一个 public 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。

要临时更改端口，请在我们通过以下命令从终端启动 jupyter notebook 服务器时指示不同的端口号。
jupyter notebook --port 9999
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。

jupyter notebook --port 9999
永久端口配置 - 通过改变配置我们可以运行Jupyter在不同的端口机器永久。请按照以下步骤操作。
- 在nano中打开配置文件

- 通过更改以下配置的值来更改端口
c.NotebookApp.port = 9999
- 通过
启动笔记本

仅供参考，运行 在 Docker 容器中并更改配置以使用端口 80：
c.NotebookApp.port = 80

在某些情况下，端口由环境变量选择（如 docker 图像）。您可以更新此变量。我想这应该适用于所有情况：
