Use USB connected drive as data directory#

/etc/fstab:

UUID=360C3D2F0C3CEB8D /var/external_drive ntfs-3g uid=33,gid=1001,rw,user,exec,umask=007 0 0

Then in config/config.php, set "var/external_drive" as directory (might require to install package for NTFS)

NFS#

sudo apt update
sudo apt install nfs-common

test:

sudo mount -t nfs 192.168.1.152:/volume1/data /var/data

fstab :

192.168.1.152:/volume1/data  /var/data   nfs      rw,sync,hard,intr  0     0

nginx#

sudo systemctl stop apache2
sudo systemctl disable apache2

sudo apt install nginx
sudo systemctl stop nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

mariadb#

sudo apt install mariadb-server mariadb-client
sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service
sudo mysql_secure_installation

# Settings: (https://forum.yunohost.org/t/configuration-nextcloud-php-fpm-pm-max-children/10911) in /etc/php/7.x/fpm/pool.d/www.conf:

pm = static
pm.max_children setting = 8 ; depends on CPU, good on Pi 3

and:

sudo service php7.3-fpm restart

Cannot login, always goes back to login page#

More often than not, that indicates a permission issue, namely in the nextcloud directory. Simply do (adapt it if needed):

sudo chown -R www-data:www-data /var/www/html/nextcloud/

php settings ignored#

If some php settings (typically, memory_limit, as shown in settings > Administration > System) seem to be ignored, you might need to restart the php-fpm service as well. For instance:

sudo service php7.3-fpm restart

Error 423#

sudo -u www-data php occ files:scan --all

Error 504 "Error when assembling chunk"#

If some php settings (typically, memory_limit, as shown in settings > Administration > System) seem to be ignored, you might need to restart the php-fpm service as well. For instance:

in /etc/php/7.x/fpm/pool.d/www.conf, if max_execution_time is low (e.g. 30), raise it to 3600 :

max_execution_time = 3600

Then restart fpm service: .. code:

sudo service php7.3-fpm restart

nextcloud locked files#

https://help.nextcloud.com/t/file-is-locked-how-to-unlock/1883

You can’t access files because they are locked and you find such errors in your logfile:

{"reqId":"0DijSqEkfOg2iyh9VD8J","remoteAddr":"xx.xx.xx.xx","app":"webdav","message":"Exception: {\"Message\":\"HTTP\\\/1.1 423 \\\"path\\\/file.extension\\\" is locked\",\"Exception\":\"OCA\\\\DAV\\\\Connector\\\\Sabre\\\\Exception\\\\FileLocked\",\"Code\":0,\"Trace\":\"#0

Manually disable locking state:

put Nextcloud in maintenance mode: edit config/config.php and change this line: 'maintenance' => true, Empty table oc_file_locks: Use tools such as phpmyadmin or connect directly to your database and run (the default table prefix is "oc<underscore>", this prefix can be different or even empty): DELETE FROM oc_file_locks WHERE 1 disable maintenance mode (undo first step). Make sure your cron-jobs run properly (you admin page tells you when cron ran the last time): https://docs.nextcloud.org/server/13/admin_manual/configuration_server/background_jobs_configuration.html 1.7k

Permanent solution (if it happens regularly)

on your own server: Use redis for this feature. It is faster and so far no problems have been reported. You can follow the instructions for memory-caching in the docs: https://docs.nextcloud.org/server/13/admin_manual/configuration_server/caching_configuration.html#id4 6.1k Shared hosting (others who can’t install redis): You can disable the file locking, edit your configuration file config/config.php: 'filelocking.enabled' => false, However, disabling is not a good solution. You can run into problems when several processes try to write to a file (especially online editors in the web-interface). In single-user and single-client environments, it’s probably less of a problem.

> sudo service php7.3-fpm restart

In addition to the package nextcloud-desktop, you can search for integrations for file managers. For instance caja-nextcloud for MATE.

Update fails on intergrity and stuck on step 5#

when trying to start update from web interface, updater fails on integrity check, and when page is reloaded it is stuck on "Step 5 is currently in process. Please reload this page later."
