Nextcloud

An opensource private cloud solution [1].

Installation

Installation is as simple as deploying a new web-site. Tips for installing on Synology bit outdated using php7

• The package can be installed in the root of a (virtual) webserver.

• The configuration is in <webroot>/config/config.php. To (re)start the initialization:

1. (re)move the config file
2. delete all tables in the nextcloud database
3. put a file named CAN_INSTALL in the config directory.
4. browse to your nextcloud webserver

• When you have unix-sockets enabled use localhost:<socketpath> as dbhost

Allow larger files to be uploaded

Change php settings:

upload_max_filesize = 16G

post_max_size = 16G As my nextcloud server is a synology diskstation:

vi /volume1/@appstore/PHP7.4/misc/php-fpm.ini

/usr/syno/sbin/synoservice --restart pkgctl-PHP7.4

Change nginx setting for the nextcloud server

client_max_body_size 0

This will disable the checking of body size. The php settings rule.

cronjob

*/5 * * * * sudo -u http php74 -f /var/www/nextcloud/cron.php

Configure this in your crontab or other job-scheduler

Client installation

sudo add-apt-repository ppa:nextcloud-devs/client
sudo apt update
sudo apt install nextcloud-client

config file

Located in the installation directory in ./config/config.php. Mine looks like:

 <?php
 $CONFIG = array (
   'maintenance' => false,
   'instanceid' => 'REMOVED',
   'passwordsalt' => 'REMOVED',
   'secret' => 'REMOVED',
   'trusted_domains' => 
   array (
     0 => 'nextcloud.local.antiperfect.org',
   ),
   'datadirectory' => '/volume1/nextcloud/',
   'dbtype' => 'mysql',
   'version' => '21.0.4.1',
   'overwrite.cli.url' => 'https://nextcloud.<mydomain>',
   'dbname' => 'nextcloud',
   'dbhost' => 'localhost:/run/mysqld/mysqld10.sock',
   'dbport' => '',
   'dbtableprefix' => 'oc_',
   'mysql.utf8mb4' => true,
   'dbuser' => 'nextcloud',
   'dbpassword' => 'REMOVED',
   'installed' => true,
   'mail_from_address' => 'nextcloud',
   'mail_smtpmode' => 'smtp',
   'mail_sendmailmode' => 'smtp',
   'mail_domain' => 'deridder.it',
   'mail_smtphost' => 'localhost',
   'mail_smtpport' => '25',
   'theme' => '',
   'loglevel' => 2,
 );

Tips and Troubleshooting

sudo -u http php74 /var/www/nextcloud/occ files:scan --all

Rescan all files (update database)

sudo -u http php74 /var/www/nextcloud/occ files:scan --path="/<username>/files/<dir to scan>"

Rescan all files in specified path

touch <file>

When everything looks OK, you fixed mounts and file permissions, try touch on the client.

A file is reported locked and it is not a file-protection issue

1. put Nextcloud in maintenance mode: edit config/config.php and change this line:

'maintenance' => true,

1. Empty table oc_file_locks (the default table prefix is oc_, this prefix can be different or even empty)
2. disable maintenance mode (undo first step).

'maintenance' => false,

Nextcloud remains in maintenance mode after upgrade

Turn off maintenance mode from the commandline and retry the upgrade from the command line.

sudo -u http php74 /var/www/nextcloud/occ maintenance:mode --off
sudo -u http php74 /var/www/nextcloud/occ upgrade
