Question

I have started a Jupyter Notebook server on my centos6.5 server.And jupyter is running like

Answer 1

Anyone who is still stuck - follow the instructions on this page.

Basically:

1. Follow the steps as initially described by AWS.

   1. Open SSH as normal.
   2. source activate python3
   3. Jupyter Notebook

2. Don't cut and paste anything. Instead open a new terminal window without closing the first one.

3. In the new window enter enter the SSH command as described in the above link.

4. Open a web browser and go to http://127.0.0.1:8157

Answer 2

I'm using Anaconda3 on Windows 10. When you install it rembember to flag "add to Enviroment Variables".

Prerequisite: A notebook configuration file

Check to see if you have a notebook configuration file, jupyter_notebook_config.py. The default location for this file is your Jupyter folder located in your home directory:

• Windows: C:\\Users\\USERNAME\\.jupyter\\jupyter_notebook_config.py
• OS X: /Users/USERNAME/.jupyter/jupyter_notebook_config.py
• Linux: /home/USERNAME/.jupyter/jupyter_notebook_config.py

If you don't already have a Jupyter folder, or if your Jupyter folder doesn't contain a notebook configuration file, run the following command:

$ jupyter notebook --generate-config

This command will create the Jupyter folder if necessary, and create notebook configuration file, jupyter_notebook_config.py, in this folder.

By default, Jupyter Notebook only accepts connections from localhost.

Edit the jupyter_notebook_config.py file as following to accept all incoming connections:

c.NotebookApp.allow_origin = '*' #allow all origins

You'll also need to change the IPs that the notebook will listen on:

c.NotebookApp.ip = '0.0.0.0' # listen on all IPs

Answer 3

Have you configured the jupyter_notebook_config.py file to allow external connections?

By default, Jupyter Notebook only accepts connections from localhost (eg, from the same computer that its running on). By modifying the NotebookApp.allow_origin option from the default ' ' to '*', you allow Jupyter to be accessed externally.

c.NotebookApp.allow_origin = '*' #allow all origins

You'll also need to change the IPs that the notebook will listen on:

c.NotebookApp.ip = '0.0.0.0' # listen on all IPs

Also see the details in a subsequent answer in this thread.

Answer 4

Try doing below step:

Following command fixes the read/write

    sudo chmod -R a+rw /home/ubuntu/certs/mycert.pem

Answer 5

if you are using Conda environment, you should set up config file again. And file location will be something like this. I did not setup config file after I created env in Conda and that was my connection problem.

C:\Users\syurt\AppData\Local\Continuum\anaconda3\envs\myenv\share\jupyter\jupyter_notebook_config.py

Answer 6

If you are still having trouble and you are running something like EC2 AWS instance, it may just be a case of opening the port through the AWS console.
