更改iPython笔记本服务器/Jupyter的默认端口
我正在尝试在防火墙后面的计算机上运行ipython笔记本电脑/jupyter服务器.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?
I am trying to run an ipython notebook / jupyter server on a machine behind a firewall. The only port which is open is port 80. So was wondering how I can change the default port from 8890 to 80?
我已经运行了以下命令ipython profile create以创建配置文件.
I have ran the following command ipython profile create to create a profile.
然后编辑ipython_notebook_config.py并将其编辑为包含以下内容:
Then edited ipython_notebook_config.py and edited it to contain the following:
c = get_config()
c.NotebookApp.port = 80
当我尝试运行python笔记本时.我收到以下错误:
When I try to run python notebook. I get the following error:
ERROR: the notebook server could not be started because no available port could be found.
但是，似乎其他任何端口都没有使用端口80.Apache无法在启动时启动，并且已被禁用.我什至用netstat查看每个端口在使用什么.
Hoever, nothing else seems to be using port 80. Apache does not boot at startup and is disabled. I have even used netstat to see what is using each port.
$ sudo netstat -lnp

某些内容已经在80上侦听，您无法将2台服务器绑定到同一端口.使用侦听80的代理，然后基于URL或地址重定向到您的其他服务器和IPython.同样不要使用80，请使用443，如果您正在运行公共服务器，则它应该通过TLS来确保安全性.
Something is already listening on 80, you cannot bind 2 servers to the same port. Use a proxy that listen to 80, and redirect to your other servers and IPython base on URL, or address. Also don't use 80, use 443, if you are running a public server it should be over TLS for security.
请注意，对于任何低端口号，您可能需要使用sudo来增加root用户的进程特权.
Note that for any low port number you might need to increase the process privileges to root, potentially using sudo.
