+==== ipywidgets ====
 then also ipywidgets is installed in /opt  because this is needed to allow connection between interactive tools running in the kernel and the user interface.

+===== nodejs npm =====
+JupyterHub also currently defaults to requiring configurable-http-proxy, which needs nodejs and npm.
+<code>
+[root@jhub ~]# dnf install nodejs npm
+Installé:
+  nodejs-1:10.24.0-1.module_el8.3.0+717+fa496f1d.x86_64      nodejs-full-i18n-1:10.24.0-1.module_el8.3.0+717+fa496f1d.x86_64      npm-1:6.14.11-1.10.24.0.1.module_el8.3.0+717+fa496f1d.x86_64
+</code>
+==== JupyterHub Configuration ====
+Create directory for jupyterhub config file and cd into it,
+<code>
+[root@jhub ~]#  mkdir -p /opt/jupyterhub/etc/jupyterhub/
+[root@jhub ~]# cd /opt/jupyterhub/etc/jupyterhub/
+</code>
+Then generate the default configuration file
+<code>
+[root@jhub jupyterhub]# /opt/jupyterhub/bin/jupyterhub --generate-config
+Writing default config to: jupyterhub_config.py
+</code>
+The generated jupyterhub_config.py file is nearly 1000 lines of commented configuration options. We will only change 1 line at this point, setting the default "spawner" to launch JupyterLab from the http-proxy URL. `grep -n c.Spawner.default jupyterhub_config.py` will show the line number that needs to be changed, 668 in my case.
+Edit jupyterhub_config.py,
+You will need to edit the configuration file to make the JupyterLab interface by the default. Set the following configuration option in your jupyterhub_config.py file:
+<code>
+#  - You can set this to `/lab` to have JupyterLab start by default, rather than Jupyter Notebook.
+#c.Spawner.default_url = ''
+c.Spawner.default_url = '/lab'
+</code>
+Further configuration options may be found in the documentation.
+==== systemd startup ====
+Create a systemd "Unit" file for starting jupyterhub,
+<code>
+[root@jhub jupyterhub]# mkdir -p /opt/jupyterhub/etc/systemd
+</code>
+edit the Unit file /opt/jupyterhub/etc/systemd/jupyterhub.service
+<code>
+[root@jhub jupyterhub]# vim /opt/jupyterhub/etc/systemd/jupyterhub.service
+[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/jupyterhub/bin"
+ExecStart=/opt/jupyterhub/bin/jupyterhub -f /opt/jupyterhub/etc/jupyterhub/jupyterhub_config.py
+[Install]
+WantedBy=multi-user.target
+</code>
+Now link that file to the directory with the system's systemd Unit files,
+<code>
+[root@jhub systemd]# ln -s /opt/jupyterhub/etc/systemd/jupyterhub.service /etc/systemd/system/jupyterhub.service
+[root@jhub systemd]# ls -l /etc/systemd/system/jupyterhub.service
+lrwxrwxrwx 1 root root 67 10 juil. 22:07 /etc/systemd/system/jupyterhub.service -> /opt/jupyterhub/etc/systemd/jupyterhub.service
+</code>
+Then tell systemd to reload its configuration files so that it knows about that new jupyterhub.service
+<code>
+[root@jpthub systemd]# systemctl daemon-reload
+</code>
+start it and enable it at boot
+<code>
+[root@jhub systemd]# systemctl start jupyterhub.service
+[root@jhub systemd]# systemctl status jupyterhub.service
+● jupyterhub.service - JupyterHub
+   Loaded: loaded (/opt/jupyterhub/etc/systemd/jupyterhub.service; linked; vendor preset: disabled)
+   Active: active (running) since Sat 2021-07-10 22:10:04 CEST; 8s ago
+[root@jhub systemd]# systemctl enable jupyterhub.service
+Created symlink /etc/systemd/system/multi-user.target.wants/jupyterhub.service → /opt/jupyterhub/etc/systemd/jupyterhub.service.
+</code>
+==== firewall ====
+open jupyterhub webservice to our local ip network
+<code>
+[root@jhub systemd]# firewall-cmd --permanent --add-rich-rule 'rule family="ipv4" source address="172.168.0.0/16" port port=8000 protocol=tcp  accept'
+success
+[root@jhub systemd]# firewall-cmd --reload
+success
+</code>
+==== jupyterhub webservice ====
+now the jupyterhub webservice is available at http://jhub.domain.fr:8000
+===== https and reverse proxy with apache =====
+  * https://jupyterhub.readthedocs.io/en/stable/reference/config-proxy.html#apache
+change the // c.JupyterHub.bind_url//  on jupyterhub config file
+<code>
+[root@jhub jupyterhub]# grep c.JupyterHub.bind_url  /opt/jupyterhub/etc/jupyterhub/jupyterhub_config.py
+#c.JupyterHub.bind_url = 'http://:8000'
+c.JupyterHub.bind_url = 'http://127.0.0.1:8000'
+</code>
+==== apache ====
+install httpd and mod_ssl package
+<code>
+[root@jhub certs]# yum install httpd mod_ssl
+</code>
+jupyterhub vhost configuration
+<code>
+[root@jhub certs]# cat /etc/httpd/conf.d/jupyterhub.conf

+==== firewall ====
+open https service in the firewall to our IP subnet
+<code>
+[root@jpthub certs]# firewall-cmd --permanent --add-rich-rule 'rule family="ipv4" source address="172.168.0/16" service name="https" log prefix="https" accept'

+===== REMOTE_USER auth =====
+we'll try to authenticate through a shibboleth SP proxy to benefit from federated access , then redirect that REMOTE_USER to jupyterhub
+  * https://github.com/cwaldbieser/jhub_remote_user_authenticator
