### Instalar Nextcloud

Verificar los [requerimientos de Nextcloud](https://docs.nextcloud.com/server/stable/admin_manual/installation/system_requirements.html#server) e instalar los paquetes de Nginx/Apache, PHP y MariaDB requeridos.

Para tener disponibles todas las versiones de PHP se recomienda instalar el repositorio ppa:ondrej/php. [**Gracias Ondřej Surý**](https://deb.sury.org/#donate).
```bash
add-apt-repository ppa:ondrej/php
```
Actualizar los índices
```bash
apt update
```
Instalamos algunos paquetes necesarios
```bash
apt install software-properties-common dirmngr apt-transport-https
```
Agregamos los paquetes de software necesarios para el núcleo de Nextcloud
```bash
apt install mariadb-server nginx libapache2-mod-php8.3 php8.3-{apcu,common,curl,fpm,gd,json,xml,mbstring,mysql,xml,zip,intl,bz2,ldap,bcmath}
```
Editamos la configuración de PHP.
```bash
nano /etc/php/8.3/fpm/php.ini
```
Cambiamos los valores predeterminados por los siguientes, y nos cercioramos de ajustar el límite_memoria de acuerdo a la capaciad máxima disponible y la zona.horaria.fecha con la ubicación/zona horaria de nuestro servidor.
```bash
date.timezone = America/Argentina/Buenos_Aires
memory_limit = 512M
upload_max_filesize = 500M
post_max_size = 600M
max_execution_time = 300
file_uploads = On
allow_url_fopen = On
display_errors = Off
output_buffering = Off
```
Guardamos el archivo y reiniciamos php8.3-fpm
```bash
systemctl restart php8.3-fpm
```
Creamos la base de datos para Nextcloud
```bash
mariadb -u root -p
```
Los siguientes comandoas crearán la nueva base de datos **basenc**, un usuario **nextcloud@localhost**, con la contraseña **secr3Ta**. Puedes ajustar los detalles de la base de datos con tu información.
```bash
CREATE DATABASE basenc;
CREATE USER nextcloud@localhost IDENTIFIED BY 'secr3Ta';
GRANT ALL PRIVILEGES ON basenc.* to nextcloud@localhost;
FLUSH PRIVILEGES;
```
Ahora que hemos configurado PHP y MariaDB, descargamos Nextcloud y configumos el directorio raíz de documentos para su instalación.
```bash
cd /var/www
sudo wget --no-check-certificate https://download.nextcloud.com/server/releases/latest.tar.bz2
sudo tar -xf latest.tar.bz2
sudo chown -R www-data:www-data nextcloud
sudo chmod -R 750 nextcloud
sudo systemctl restart nginx
```
A continuación configuramos el servidor web editando el archivo /etc/nginx/conf.d/nxtcld.conf
```bash
upstream php-handler {
    server unix:/var/run/php/php8.3-fpm.sock;
}

# Set the `immutable` cache control options only for assets with a cache busting `v` argument

Reiniciamos nginx
```bash
systemctl restart nginx
```
Nos conectamos al flamante Nextcloud en a http://nxtcd.edu.ar, ingresamos los datos de la cuenta de administrador y de la base de datos que definimos para finalizar la configuración.
