How to run jupyter notebook in the background ? No need to keep one terminal for it

Question

Often we run jupyter notebook to pop up a page in browser to use notebook. However, the terminal opening the server remains there. Is there a way that we can cl

Answer 1

You can put the process into the background by using jupyter notebook &. You can close the terminal afterwards and the process will still be running.

Answer 2

Detach Jupyter process from the controlling terminal and send all its input and output data to /dev/null which is a special device file that writes-off any data written to it.

jupyter notebook </dev/null &>/dev/null &

Lazy people like me would prefer to edit ~/.bash_aliases and create an alias:

alias jnote='jupyter notebook </dev/null &>/dev/null &'

Answer 3

Not real sophisticated but it gets the job done:

#! /bin/bash

#probably should change this to a case switch

if [ "$1" == "end" ]
    then
        echo
        echo "Shutting Down jupyter-notebook"
        killall jupyter-notebook
        echo
      exit 0
 fi

if [ "$1" == "-h" ]
   then
        echo   
        echo "To start  : jnote <port> [default 8888]" 
        echo "To end    : jnote end"
        echo "This help : jnote -h"
        echo
      exit 0
 fi

#cast from string
PORT=$(($1))

RETURN=0
PID=0

if [ "$PORT" == "0" ] || [ "$PORT" == "" ]; then PORT=8888; fi

echo
echo "Starting jupyter-notebook"

#background and headless, set port, allow colab access, capture log, don't open browser yet

nohup jupyter notebook \
 --NotebookApp.allow_origin='https://colab.research.google.com' \
 --port=$PORT --NotebookApp.port_retries=0 \
 --no-browser >~/jnote.log 2>&1 &

RETURN=$?
PID=$!

#Wait for bg process to complete - add as needed
sleep 2

if [ $RETURN == 0 ]
   then
        echo
        echo "Jupyter started on port $PORT and pid $PID"
        echo "Goto `cat ~/jnote.log | grep localhost: | grep -v NotebookApp`"
        echo
      exit 0
   else
        echo 
        echo "Jupyter failed to start on port $PORT and pid $PID with return code $RETURN"
        echo "see ~/jnote.log"
        echo
      exit $RETURN
 fi

Answer 4

jupyter notebook & >> disown  

put the process into the background by using jupyter notebook &
then type disown or disown <the process id>
you can close the terminal now

Answer 5

This works for me when running a jupyter notebook server in the background.

$> nohup jupyter notebook --allow-root > error.log &

Stop the nohup jupyter notebook is simple.

First, find the pid of jupyter:

$> ps -ef| grep jupyter

e.g output like:

root 11417 2897 2 16:00 pts/0 00:04:29 /path/to/jupyter-notebook

Then kill the process:

$> kill -9 11417

You can also simplify this by storing the pid with:

$> nohup jupyter notebook --allow-root > error.log & echo $!> pid.txt

i.e, you can stop the notebook with:

$> kill -9 $(cat pid.txt)

---

An alternative way to stop the jupyter notebook is quit from the notebook page.
