Changing the default port for iPython notebook server / Jupyter
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?
I have ran the following command ipython profile create to create a profile.
Then edited ipython_notebook_config.py and edited it to contain the following:
c = get_config()
c.NotebookApp.port = 80
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.
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

jupyter notebook --ip=0.0.0.0 --port=80 or
ipython notebook --ip=0.0.0.0 --port=80
is what i did to run ipython in my vagrant box. (Opened up the ports on the vagrant box to access it on my host mac)
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]
Incase the port is already occupied, see what's blocking it - inmy case it was an old instance of ipython which had not been terminated properly. I kiiled them all with this command
ps auxww | grep 'ipython' | awk '{print $2}' | xargs sudo kill -9
To change port temporarily, indicate a different port number when we start jupyter notebook server from a terminal by firing following command.
jupyter notebook --port 9999

In Jupyter we can start the notebook on different port by two ways.
- Temporary port - By mentioning the port in args like below command we can run Jupyter on that port. But we have to mention the port in the command argument whenever we need to run Jupyter in a different port.
jupyter notebook --port 9999
-
Permanent port Configuration - By changing the configuration we can run Jupyter on different port on the machine permanently. Please follow the below steps for that.
- Open the configuration file in nano
nano ~/.jupyter/jupyter_notebook_config.py- Change the port by changing the value of the below configuration
c.NotebookApp.port = 9999- start the notebook by
jupyter notebook
Bingo!!!
