1. Ajout du dépôt [[sury|https://packages.sury.org/php/]] pour PHP, en suivant les indications du [[README|https://packages.sury.org/php/README.txt]] :
```
# cd /tmp
# wget https://packages.sury.org/debsuryorg-archive-keyring.deb
# dpkg -i ./debsuryorg-archive-keyring.deb
# echo "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $(awk -F '=' '/VERSION_CODENAME=/ {print $NF}' /etc/os-release) main" > /etc/apt/sources.list.d/php.list
# apt update
# rm debsuryorg-archive-keyring.deb
```
1. Installation des paquets php nécessaires pour Nextcloud \
**NB**, pour vérifier les modules installés : `php -m | grep -i <module_name>`
```
# apt install php8.2-{bcmath,cli,common,ctype,curl,dom,exif,fpm,ftp,gd,gmp,imagick,imap,intl,ldap,mbstring,posix,smbclient,xml,xsl,zip}
```
1. Éditer la configuration de PHP FPM : `etc/php/8.x/fpm/php.ini`
- _A modifier_ : **paramètres opcache**, **tiemzone** et **la limite mémoire**.
```

# that file is correctly served; if it doesn't, then the request is passed to
# the front-end controller. This consistent behaviour means that we don't need
# to specify custom rules for certain paths (e.g. images and other assets,
# `/updater`, `/ocm-provider`, `/ocs-provider`), and thus
# `try_files $uri $uri/ /index.php$request_uri`

### Installation de PostgreSQL
1. Installer les paquets : `# apt install postgresql postgresql-client php8.2-pgsql`
1. Créer l'utilisateur et la base de données (cf. <https://docs.nextcloud.com/server/latest/admin_manual/configuration_database/linux_database_configuration.html#postgresql-database>) :
```
# sudo -u postgres psql
postgres=# CREATE USER ncadmin
WITH ENCRYPTED PASSWORD '${ncadmin_DB_PASSWORD}';
postgres=# CREATE DATABASE nextcloud
WITH OWNER ncadmin;
postgres=# GRANT ALL PRIVILEGES
ON DATABASE nextcloud
TO ncadmin;
postgres=# exit
#
```
1. Configurer la connexion en socket (et mapping) :
```
# sed -i -e '/local all postgres peer/a local nextcloud all ident map=nextcloud' \
/etc/postgresql/15/main/pg_hba.conf
# cat <<EOF >>/etc/postgresql/15/main/pg_ident.conf
nextcloud www-data ncadmin
EOF
#
```
1. Recharger la configuration :
```
# pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
15 main 5432 online postgres /var/lib/postgresql/15/main /var/log/postgresql/postgresql-15-main.log
# pg_ctlcluster 15 main reload
#
```
#### Sauvegarde de la base des données PostgreSQL
**ToDo**
### Installation de Nextcloud
1. Télécharger et décompresser les fichiers :
```
# cd /srv
# wget https://download.nextcloud.com/server/releases/latest-28.tar.bz2
# wget https://download.nextcloud.com/server/releases/latest-28.tar.bz2.sha512
# sha512sum -c latest-28.tar.bz2.sha512
# tar xvf latest-28.tar.bz2
# chown -R www-data:www-data /srv/nextcloud
```
1. Compléter l'installation avec la commande OCC :
```
# cd /srv/nextcloud
# sudo -u www-data \
php occ maintenance:install --database "pgsql" \
--database-host "localhost:/run/postgresql" \
--database-name "nextcloud" \
--database-user "ncadmin" \
--database-pass "${ncadmin_DB_PASSWORD}" \
--admin-user "${ADMINUSER}" \
--admin-pass "${ADMINUSER_PASSWORD}" \
--admin-email "it@${TLD}"
```
1. Corriger la configuration générée : \
**ATTENTION**, le data directory se trouve en dehors du dossier racine `/srv/nextcloud/`, pourquoi ?
```
# systemctl stop nginx.service
# cd /srv/nextcloud
# mv -i data/ ../nextcloud-data
# sed -i -e "s/\(0 =>\) 'localhost',/\1 '${WEBSITENAME.TLD}',/" \
-e "s/\('datadirectory' =>\) '\/srv\/nextcloud\/data',/\1 '\/srv\/nextcloud-data',/" \
-e "s/\('overwrite.cli.url' =>\) 'http:\/\/localhost',/\1 'http:\/\/${WEBSITENAME.TLD}',/" \
./config/config.php
# systemctl start nginx.service
```
1. Se connecter à l'adresse <https://${WEBSITENAME.TLD}> pour confirmer que tout est OK
#### Installation de Redis et APCu
1. Installer les paquets : `# apt install redis php8.2-apcu php8.2-redis`
1. Stopper le service : `# systemctl stop redis.service`
1. Ajouter l'utilisateur `www-data` au groupe `redis` afin que Nextcloud puisse accéder au socket (cf. <https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/caching_configuration.html#id2>) : \
**ATTENTION**, une meilleure solution serait d'utiliser `systemd-tmpfiles` en ajoutant une ACL pour l'utilisateur `www-data` à la volée quand le socket apparaître !
```
# adduser www-data redis
# systemctl restart php8.2-fpm.service
#
```
1. Configurer le logiciel pour communiquer en socket :
```
# cat <<EOF >>/etc/redis/redis.conf
### Nextcloud
include /etc/redis/local_socket.conf
EOF
# cat <<EOF >/etc/redis/local_socket.conf
### Nextcloud
unixsocket /run/redis/redis-server.sock
unixsocketperm 770
EOF
#
```
1. Redémarrer le service : `# systemctl restart redis.service`
1. Configurer Nextcloud pour utiliser Redis et APCu :
```
# cd /srv/nextcloud/
# vi config/config.php
[ajouter à la fin before la dernière ");":
'memcache.local' => '\OC\Memcache\APCu',
'memcache.locking' => '\OC\Memcache\Redis',

### Installation de PostgreSQL
1. Installer les paquets : `# apt install postgresql postgresql-client php8.2-pgsql`
1. Créer l'utilisateur et la base de données (cf. <https://docs.nextcloud.com/server/latest/admin_manual/configuration_database/linux_database_configuration.html#postgresql-database>) :
```
# sudo -u postgres psql
postgres=# CREATE USER ncadmin
WITH ENCRYPTED PASSWORD '${ncadmin_DB_PASSWORD}';
postgres=# CREATE DATABASE nextcloud
WITH OWNER ncadmin;
postgres=# GRANT ALL PRIVILEGES
ON DATABASE nextcloud
TO ncadmin;
postgres=# exit
#
```
1. Configurer la connexion en socket (et mapping) :
```
# sed -i -e '/local all postgres peer/a local nextcloud all ident map=nextcloud' \
/etc/postgresql/15/main/pg_hba.conf
# cat <<EOF >>/etc/postgresql/15/main/pg_ident.conf
nextcloud www-data ncadmin
EOF
#
```
1. Recharger la configuration :
```
# pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
15 main 5432 online postgres /var/lib/postgresql/15/main /var/log/postgresql/postgresql-15-main.log
# pg_ctlcluster 15 main reload
#
```
#### Sauvegarde de la base des données PostgreSQL
**ToDo**
### Installation de Nextcloud
1. Télécharger et décompresser les fichiers :
```
# cd /srv
# wget https://download.nextcloud.com/server/releases/latest-28.tar.bz2
# wget https://download.nextcloud.com/server/releases/latest-28.tar.bz2.sha512
# sha512sum -c latest-28.tar.bz2.sha512
# tar xvf latest-28.tar.bz2
# chown -R www-data:www-data /srv/nextcloud
```
1. Compléter l'installation avec la commande OCC :
```
# cd /srv/nextcloud
# sudo -u www-data \
php occ maintenance:install --database "pgsql" \
--database-host "localhost:/run/postgresql" \
--database-name "nextcloud" \
--database-user "ncadmin" \
--database-pass "${ncadmin_DB_PASSWORD}" \
--admin-user "${ADMINUSER}" \
--admin-pass "${ADMINUSER_PASSWORD}" \
--admin-email "it@${TLD}"
```
1. Corriger la configuration générée : \
**ATTENTION**, le data directory se trouve en dehors du dossier racine `/srv/nextcloud/`, pourquoi ?
```
# systemctl stop nginx.service
# cd /srv/nextcloud
# mv -i data/ ../nextcloud-data
# sed -i -e "s/\(0 =>\) 'localhost',/\1 '${WEBSITENAME.TLD}',/" \
-e "s/\('datadirectory' =>\) '\/srv\/nextcloud\/data',/\1 '\/srv\/nextcloud-data',/" \
-e "s/\('overwrite.cli.url' =>\) 'http:\/\/localhost',/\1 'http:\/\/${WEBSITENAME.TLD}',/" \
./config/config.php
# systemctl start nginx.service
```
1. Se connecter à l'adresse <https://${WEBSITENAME.TLD}> pour confirmer que tout est OK
#### Installation de Redis et APCu
1. Installer les paquets : `# apt install redis php8.2-apcu php8.2-redis`
1. Stopper le service : `# systemctl stop redis.service`
1. Ajouter l'utilisateur `www-data` au groupe `redis` afin que Nextcloud puisse accéder au socket (cf. <https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/caching_configuration.html#id2>) : \
**ATTENTION**, une meilleure solution serait d'utiliser `systemd-tmpfiles` en ajoutant une ACL pour l'utilisateur `www-data` à la volée quand le socket apparaître !
```
# adduser www-data redis
# systemctl restart php8.2-fpm.service
#
```
1. Configurer le logiciel pour communiquer en socket :
```
# cat <<EOF >>/etc/redis/redis.conf
### Nextcloud
include /etc/redis/local_socket.conf
EOF
# cat <<EOF >/etc/redis/local_socket.conf
### Nextcloud
unixsocket /run/redis/redis-server.sock
unixsocketperm 770
EOF
#
```
1. Redémarrer le service : `# systemctl restart redis.service`
1. Configurer Nextcloud pour utiliser Redis et APCu :
```
# cd /srv/nextcloud/
# vi config/config.php
[ajouter à la fin before la dernière ");":
'memcache.local' => '\OC\Memcache\APCu',
'memcache.locking' => '\OC\Memcache\Redis',

#### Exemple du fichier `config.php`
**ATTENTION**, le deuxième dossier pour les applications, _i.e._ `/srv/nextcloud/apps2`, est outil pendant la mise à jour manuelle dans le cas des différentes versions des applications (comme conseillé par [la documentation officielle Nextcloud](https://docs.nextcloud.com/server/latest/admin_manual/apps_management.html#using-custom-app-directories)), à vérifier si c'est toujours le cas !
