Nextcloud on Debian

Nextcloud is a flexible file synchronization and sharing solution.Nextcloud includes Nextcloud server( run on linux) and Nextcloud client.Nextcloud is a Free and Open Source community supported,with all enterprise features. In this doc lets try to install nextcloud server over Nginx and access it over browser client.

Nginx

Nginx is Free and Open Source web server which is now also used as reverse proxy,HTTP cache and load balancer.To setup nextcloud we can choose either nginx or apache as webserver. Install and enable nginx service on the server

$ sudo apt install nginx -y
$ sudo systemctl start nginx
$ sudo systemctl enable nginx

Installation Steps

Prerequisites for mannual installation.

https://docs.nextcloud.com/server/latest/admin_manual/installation/source_installation.html#prerequisites-for-manual-installation

Install php8.0 from deb.sury.org

Installing PHP from a third party repository https://deb.sury.org/ which contains the deb packaged version of the latest php and its modules. This repository supports both Ubuntu and Debian.

if [ "$(whoami)" != "root" ]; then
    SUDO=sudo
fi

${SUDO} apt-get update
${SUDO} apt-get -y install lsb-release ca-certificates curl
${SUDO} curl -sSLo /usr/share/keyrings/deb.sury.org-php.gpg https://packages.sury.org/php/apt.gpg
${SUDO} sh -c 'echo "deb [signed-by=/usr/share/keyrings/deb.sury.org-php.gpg] https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list'
${SUDO} apt-get update

$ sudo apt policy php8.0
# check for any latest updated php package

sudo apt install php8.0-xmlreader php8.0-curl php8.0-gd php8.0-mbstring php8.0-zip php8.0-fpm

Database connectors (either choose from MySQL/MariaDB and Postgresql)

$ sudo apt install mariadb-server php8.0-mysql

Caching

$sudo apt install redis php8.0-redis

https://docs.nextcloud.com/server/latest/admin_manual/installation/nginx.html

vim /etc/php/8.0/cli/php.ini
update date.timezone = Asia/Kolkata

cd /var/www
sudo wget https://download.nextcloud.com/server/releases/latest.zip
sudo chown www-data:www-data /var/www/nextcloud -R

> create database nextcloud_db;
> create user nextcloud_user@localhost identified by 'deeproot';
> grant all privileges on nextcloud_db.* to nextcloud_user@localhost identified by 'deeproot';
> flush privileges
> exit

    # Specify how to handle directories -- specifying `/index.php$request_uri`
    # here as the fallback means that Nginx always exhibits the desired behaviour
    # when a client requests a path that corresponds to a directory that exists
    # on the server. In particular, if that directory contains an index.php file,
    # 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`
