The subdomain is jupyter.flowerhouse.at which is handled by the ReverseProxy.

Basic Setup

Installation

Install required packages

apt install python3-pip npm

Install JupyterHub, responsible for managing multiple users

python3 -m pip install jupyterhub

Install Proxy needed by JupyterHub

npm install -g configurable-http-proxy

Install webinterface and notebook

python3 -m pip install jupyterlab notebook

Configuration

Create config file

Create folder for config

mkdir /etc/jupyterhub

Generate config file

jupyterhub --generate-config -f /etc/jupyterhub/jupyterhub_config.py

Create systemd service

Create service file

nano /etc/systemd/system/jupyter.service

Add this content to file

[Unit]
Description=Jupyterhub
After=syslog.target network.target

[Service]
User=root
Environment="PATH=/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/opt/anaconda3/bin"
ExecStart=jupyterhub -f /etc/jupyterhub/jupyterhub_config.py

[Install]
WantedBy=multi-user.target

Reload systemd

systemctl daemon-reload

Start Jupyter and check if its running

systemctl start jupyter
systemctl status jupyter

Start Jupyter at boot

systemctl enable jupyter

Create/Add user

Create new user

adduser [username]

Extensions/Kernels

SageMath

Install SageMath Kernel

apt install sagemath

MatLab

Install MatLab

Mount iso from USB via Proxmox to LXC

mount -o loop,ro /media/sda/MatLab/Matlab910R2021a_Lin64.iso /rpool/data/subvol-111-disk-0/mnt

Create installation procedure file and add this

nano /input.txt

Start installation with:

cd /mnt
./install -inputFile /input.txt

Check log if installation was successful

nano ./InstallMatLab.log

Delete log

rm ./InstallMatLab.log

Unmount ISO in ProxMox

umount /rpool/data/subvol-111-disk-0/mnt

Open .bashrc

nano /etc/bash.bashrc

Add to end of file

export MATLAB_ROOT_DIR="/usr/local/Polyspace/R2021a"

Apply changes by executing the command

source /etc/bash.bashrc

Check if if works:

echo $MATLAB_ROOT_DIR
