Mettre en place un serveur de déploiement Clonezilla

Solution 1 - dépôts DRBL (recommandé)

Ajouter la clé DRBL (voir ici) :

Prérequis

• L'ancienne méthode avec apt-key :

root@host:~# wget -q https://drbl.org/GPG-KEY-DRBL -O- | apt-key add -

• Nouvelle méthode, étant donné que apt-key semble déprécié :

root@host:~# curl -s https://drbl.org/GPG-KEY-DRBL | gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/GPG-KEY-DRBL.gpg --import

root@host:~# chmod 644 /etc/apt/trusted.gpg.d/GPG-KEY-DRBL.gpg

• Ajouter le dépôt drbl dans le fichier source.list :

root@host:~# echo "deb http://free.nchc.org.tw/drbl-core drbl stable" >> /etc/apt/sources.list

Installer et configurer DRBL

• Installer le paquet DRBL :

root@host:~# apt update

root@host:~# apt-get install drbl

• Éditer le fichier /etc/drbl/drbl.conf pour activer la compatibilité secure boot :

# uEFI network secure boot for clients. This is still in testing.
secure_boot_client="yes"

• Installer le serveur DRBL :

root@host:~# drblsrv -i

• Pousser la configuration :

root@host:~# drblpush -i

The public IP address of this server is NOT found.
Which ethernet port in this server is for public Internet accsess, not for DRBL connection?
Available ethernet ports in this server:
ens192 (192.168.1.10), ens224 (192.168.10.1), 
[ens192] 
[…]
What is the initial number do you want to use in the last set of digits in the IP (i.e. the initial value of d in the IP address a.b.c.d) for DRBL clients connected to this ethernet port ens224.
[1] 10
******************************************************
How many DRBL clients (PC for students) connected to DRBL server's ethernet network interface ens224 ?
Please enter the number: 
[12] 50

------------------------------------------------------
In the system, there are 3 modes for diskless linux services:
[0] Full DRBL mode, every client has its own NFS based /etc and /var.
[1] DRBL SSI (Single system image) mode, every client uses tmpfs based /etc and /var. In this mode, the loading and necessary disk space of server will be lighter. NOTE! (a) The client machine memory is recommended at least 256 MB. (b) The setting and config files of client will not be saved to the DRBL server! They are just used once and will vanish after the machine shutdowns! Besides, if you modify any file in the template client (located in /tftpboot/nodes), you have to run drbl-gen-ssi-files to create the template tarball in /tftpboot/node_root/drbl_ssi/. (c) If you want to provide some file to overwrite the setting in the template tarball when client boots, check /tftpboot/node_root/drbl_ssi/clients/00_README for more details.
[2] I do NOT want to provide diskless Linux service to client.
Which mode do you prefer?
[0] 2
No diskless Linux for client is the system.
******************************************************
------------------------------------------------------
In the system, there are 4 modes available for clonezilla:
[0] Full Clonezilla mode, every client has its own NFS based /etc and /var.
[1] Clonezilla box mode, every client uses tmpfs based /etc and /var. In this mode, the loading and necessary disk space of server will be lighter than that in Full Clonezilla mode. Note! In Clonezilla box mode, the setting and config files of client will not be saved to the DRBL server! They just use once and will vanish after the machine shutdowns!
[2] I do NOT want clonezilla.
[3] Use Clonezilla live as the OS (Operating System) of clients.
Which mode do you prefer?
[0] 3
Use Clonezilla live as the OS (Operating System) of clients when running Clonezilla job.
******************************************************
******************************************************
What's the Clonezilla live release branch for the clients?
[0]: stable (Debian-based)
[1]: testing (Debian-based)
[2]: alternative stable (Ubuntu-based)
[3]: alternative testing (Ubuntu-based)
If unsure, choose [2]: alternative stable.
[2] 
From Ubuntu 19.10, only amd64 (x86-64) release of Clonezilla live is available.
******************************************************
The CPU arch for clients when running Clonezilla job: amd64

Corriger les fichiers de configuration UEFI et BIOS

Peu importe la méthode utiliser pour installer DRBL, les fichiers de configuration de démarrage devront être modifiés, sinon il ne sera pas possible de démarrer sur Clonezilla.
