Installation

Nextcloud will be using apache

[shroot]

apt install mlocate apache2 libapache2-mod-php mariadb-client mariadb-server wget unzip bzip2 curl php php-common php-curl php-gd php-mbstring php-mysql php-xml php-zip php-intl php-apcu php-redis php-bcmath php-gmp php-imagick

[/shroot]

Not found: php-http-request python-certbot-apache

No password set

mariadb -u root -p

CREATE DATABASE nextcloud;

For UTF8 support use this instead:

CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
GRANT ALL ON nextcloud.* TO 'nextcloud'@'localhost' IDENTIFIED BY '{PASSWORD}';
FLUSH PRIVILEGES;

Exit the MariaDB prompt

Download Nextcloud into /var/www

[shroot]

wget https://download.nextcloud.com/server/releases/nextcloud-[VERSION].tar.bz2
tar -xf nextcloud-[VERSION].tar.bz2

[/shroot]

Change owner to the apache user

[shroot]

chown -Rfv www-data:www-data /var/www/nextcloud

[/shroot]

Create nextcloud configuration for apache

[shroot]

vi /etc/apache2/sites-available/nextcloud.conf

[/shroot]

Enable nextcloud and disable the default site

[shroot]

a2ensite nextcloud.conf && a2dissite 000-default.conf

[/shroot]

Edit ports.conf for apache2 to only bind the addresses you need

[shroot]

systemctl restart apache2

[/shroot]

Cron

To execute regular jobs, I personally use cron.
Edit crontab as the www-data user.

[shroot]

su -s /bin/sh -c 'crontab -e' www-data

[/shroot]

Add this following line:

*/5 * * * * php -f [NEXTCLOUD DIR]/cron.php

Configuration

The main config file is [NEXTCLOUD DIR]/config/config.php

Automatic Trash clearing

See this page for more options

This settings keeps the files for 15 days, unless drive space is getting low.
In that case it delets them earlier.

'trashbin_retention_obligation' => 'auto, 15',

Trust Proxy

This disables the warning of untrusted proxy in the webinterface.

'trusted_proxies' =>
    array (
	      0 => '[PROXY IP]',
),

Trusted Domains

Array of trusted domains.

'trusted_domains' =>
    array (
        0 => '[DOMAIN 1]',
        1 => '[DOMAIN 2]',
),

Maintenance

Maintenance Mode

Enable maintenance mode to prevent data inconsistencies

[shroot]

su -s /bin/sh -c 'php /var/www/nextcloud/occ maintenance:mode --on' www-data

[/shroot]

To disable maintenance mode again, run the same command with --off instead of --on

Upgrade with CLI

[shroot]

su -s /bin/sh -c 'php /var/www/nextcloud/updater/updater.phar' www-data

[/shroot]

Always check the admin status page after an upgrade. Sometimes additional steps are needed to fully complete the upgrade

Missing indices in database

The missing indices can be added using occ

[shroot]

su -s /bin/sh -c 'php /var/www/nextcloud/occ db:add-missing-indices' www-data

[/shroot]

Backup Database

Dump database to file

NOTE: The password needs to be inserted directly after -p without any space

mysqldump --single-transaction -h [SERVER] -u [USERNAME] -p[PASSWORD] [DB NAME] > nextcloud-sqlbkp_`date +"%Y%m%d"`.bak

Official documentation

Backup Script

#!/bin/bash
set -euo pipefail

server=
username=
password=
db_name=

sudo mkdir -p /var/www/database-backup

sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --on

mysqldump --single-transaction -h $server -u $username -p$password $db_name | sudo tee /var/www/database-backup/nextcloud-sqlbkp_`date +"%Y%m%d"`.bak

sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --off

Restore Database

mariadb -h [SERVER] -u [USERNAME] -p[PASSWORD] -e "DROP DATABASE nextcloud"
mariadb -h [SERVER] -u [USERNAME] -p[PASSWORD] -e "CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci"

mariadb -h [SERVER] -u [USERNAME] -p[PASSWORD] [DB NAME] < nextcloud-sqlbkp.bak

Onlyoffice Container

Integrating onlyoffice, requires setting the correct Content Security Policy headers on the webserver. Using CSP also introduces blockages in Nextcloud that have to be fixed. The console view is your friend for finding every issue.
For my installation, the headers needed to be set like this.

Content-Security-Policy "default-src 'self' 'unsafe-inline' 'unsafe-eval' data: [ONLYOFFICE DOMAIN NAME];"

[shroot]

podman run -itd --name onlyoffice -p 8080:80 \
    -e JWT_SECRET=[SECRET KEY] \
    docker.io/onlyoffice/documentserver
