Il est basé sur Ubuntu 18.06 server

Si il est nécessaire d'augmenter la taille de la partition principale, les commandes suivantes peuvent être exécutées.

sudo lvextend -L20G /dev/mapper/ubuntu--vg-ubuntu--lv
sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv

Trouver le volume group du logical volume

lvdisplay -l nom_du_lv

Vérifier qu’il reste assez de place sur le volume group du filesystem

vgdisplay nom_du_vg

sudo mdadm --create --verbose /dev/md0 --metadata 1.2 --level=mirror --raid-devices=2 /dev/sda1 /dev/sdb1
sudo reboot
cat /proc/mdstat
 
sudo mdadm --detail --scan >> my_mdadm.conf

Ensuite j'ai rajouté une ligne (celle du fichier my_mdadm.conf dans le fichier /etc/mdadm/mdadm.conf). Mais je ne sais pas si c'est utile :

# mdadm.conf
#
# !NB! Run update-initramfs -u after updating this file.
# !NB! This will ensure that initramfs has an uptodate copy.
#
# Please refer to mdadm.conf(5) for information about this file.

Installer lxd

snap install lxd

configurer l'utilisateur courant pour qu'il puisse gérer les conteneurs lxd

sudo usermod -a -G lxd $USER

Un bridge réseau est ajouté dans le fichier /etc/netplan/50-cloud-init.yaml

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    version: 2
    renderer: networkd
    ethernets:
        enp3s0:
            dhcp4: no 
    bridges:
        br0:
            dhcp4: yes
            interfaces:
                - enp3s0

exécuter la commande

sudo lxd init

Ensuite lors des questions, mettre toutes les options par défaut excepté

• le type de stockage : zfs
• le bridge existe déjà : br0
• accès au réseau : yes

Création d'un conteneur

lxc project create mes-sites -c features.images=false -c features.profiles=false
lxc project switch mes-sites
lxc launch ubuntu:22.04 webserver
lxc launch ubuntu:22.04 dbserver

Se connecter au conteneur

lxc exec dbserver -- sudo --login --user ubuntu

Arréter un conteneur

lxc stop dbserver

sudo snap stop lxd
mv /var/snap/lxd /media/stockage/lxd-container

modifier /etc/fstab en ajoutant la ligne :

/media/stockage/system/lxd-containers   /var/snap/lxd                none bind 0 0

Lister les images

lxc list

lxc export {container} /path/to/{container}-backup-$(date +'%m-%d-%Y').tar.xz

Restauration

lxc import /path/to/{container}-backup.tar.xz

Installer le serveur nfs:

sudo apt install nfs-kernel-server

Modifier /etc/fstab:

[...]
/media/stockage/multimedia       /export/multimedia          none bind 0 0
/media/stockage/famille          /export/famille             none bind 0 0
/media/stockage/partage          /export/partage             none bind 0 0

/media/stockage/repositories     /export/repositories        none bind 0 0
[...]

Ensuite modifier le fichier /etc/exports:

# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#

/export/multimedia      192.168.1.0/24(rw,no_subtree_check,async)
/export/repositories    192.168.1.0/24(rw,no_subtree_check,async)
/export/famille         192.168.1.0/24(rw,no_subtree_check,async)
/export/partage         192.168.1.0/24(rw,no_subtree_check,async)

/export/home/francois   192.168.1.0/24(rw,no_subtree_check,async)

Les commandes suivantes sont utilisées pour l'install:

sudo apt install apache2

Génération des clefs SSL

sudo mkdir /etc/apache2/ssl
sudo openssl req -x509 -nodes -days 1095 -newkey rsa:2048 -out /etc/apache2/ssl/server.crt -keyout /etc/apache2/ssl/server.key
sudo chmod -R www-data.www-data /etc/apache2/ssl

Activation du site https et désactivation du site http

sudo a2enmod ssl
sudo a2enmod rewrite
sudo a2enmod headers
sudo a2dissite 000-default
sudo a2ensite default-ssl

Puis modification du fichier /etc/apache2/ports.conf

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default.conf

#Listen 80

<IfModule ssl_module>
        Listen 443
</IfModule>

<IfModule mod_gnutls.c>
        Listen 443
</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Ensuite modification du fichier /etc/apache2/sites-enabled/default-ssl.conf

[...]

                #   A self-signed (snakeoil) certificate can be created by installing
                #   the ssl-cert package. See
                #   /usr/share/doc/apache2/README.Debian.gz for more info.
                #   If both key and certificate are stored in the same file, only the
                #   SSLCertificateFile directive is needed.
                SSLCertificateFile     /etc/apache2/ssl/server.crt
                SSLCertificateKeyFile  /etc/apache2/ssl/server.key

[...]

Configuration du serveur

Le fichier /etc/apache2/apache2.conf est modifié :

[...]

# Sets the default security model of the Apache2 HTTPD server. It does
# not allow access to the root filesystem outside of /usr/share and /var/www.
# The former is used by web applications packaged in Debian,
# the latter may be used for local directories served by the web server. If
# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.

sudo apt install mysql-server

Mot de passe root

sudo systemctl stop mysql
sudo mkdir /var/run/mysqld; sudo chown mysql /var/run/mysqld
sudo mysqld_safe --skip-grant-tables &
sudo mysql --user=root mysql

Dans le prompt mysql

update user set authentication_string=PASSWORD('new-password') where user='root';
flush privileges;

Et ensuite, tuer le service démarré en “safe”

Il faut changer le mode d'autentification root

mysql> SELECT User, Host, plugin FROM mysql.user;

| mysql.session    | localhost | mysql_native_password |
| mysql.sys        | localhost | mysql_native_password |
| debian-sys-maint | localhost | mysql_native_password |
+------------------+-----------+-----------------------+

changement du mode

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mypassword';
Query OK, 0 rows affected (0.00 sec)
 
mysql> SELECT User, Host, plugin FROM mysql.user;
+------------------+-----------+-----------------------+
