ownCloud

ownCloud is a file sync and share platform.

Default Login Credentials

After installing from SynoCommunity:

  • Username: admin
  • Password: admin

Warning

Change these credentials immediately after logging in.

Using the occ Command

The occ command (ownCloud console) is a powerful command-line tool for administrative tasks.

1. Enable SSH

Ensure SSH is enabled on your DiskStation. See FAQ-ssh for instructions.

2. Define Shortcuts

oc_php=/usr/local/bin/php74

For DSM 6: 

oc_occ=/var/services/web/owncloud/occ
oc_usr=http

For DSM 7: 

oc_occ=/var/services/web_packages/owncloud/occ
oc_usr=sc-owncloud

3. Run occ Commands

sudo -u $oc_usr $oc_php $oc_occ --version

Replace --version with any other occ command you need to run.

Files Not in Sync

If your files are not updating correctly in the Files view after modifying them outside of the web interface (e.g., via WebDAV), ownCloud may not be detecting changes automatically.

Fix Steps

  1. Set up occ as described above

  2. Enable maintenance mode: 

    sudo -u $oc_usr $oc_php $oc_occ maintenance:mode --on

  3. Adjust filesystem change detection: 

    sudo -u $oc_usr $oc_php $oc_occ config:system:set --type=integer filesystem_check_changes --value 1

  4. Disable maintenance mode: 

    sudo -u $oc_usr $oc_php $oc_occ maintenance:mode --off

Database Migration (SQLite to MariaDB)

Starting with version 10.15.0, the ownCloud package transitions from SQLite to MariaDB back-end. This includes optimized configurations to eliminate all warnings in the settings screen.

Prerequisites

  1. Install redis from the SynoCommunity repository
  2. Enable SSH and connect to your DiskStation

Setup Shortcuts

oc_php=/usr/local/bin/php74
oc_sql=/usr/local/mariadb10/bin/mysql

For DSM 6: 

oc_home=/var/services/web/owncloud
oc_occ=/var/services/web/owncloud/occ
oc_usr=http

For DSM 7: 

oc_home=/var/services/web_packages/owncloud
oc_occ=/var/services/web_packages/owncloud/occ
oc_usr=sc-owncloud

Migration Steps

  1. Save your MySQL root password: 

    oc_rpwd=[your MySQL root password]

  2. Set a random password for the database user: 

    oc_upwd=$(LC_ALL=C tr -dc 'A-Za-z0-9:@.,/+!=-' </dev/urandom | head -c 30; echo)

  3. Enable maintenance mode: 

    sudo -u $oc_usr $oc_php $oc_occ maintenance:mode --on

  4. Add HSTS to Apache configuration: 

    sudo tee -a $oc_home/.htaccess > /dev/null <<EOF
<IfModule mod_headers.c>
Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains"
</IfModule>
EOF
sudo chown $oc_usr $oc_home/.htaccess

  5. Prepare for migration: 

    sudo -u $oc_usr $oc_php $oc_occ config:system:set mysql.utf8mb4 --value=true

  6. Open MariaDB 10 in DSM and enable the TCP/IP connection

  7. Create a new MySQL database: 

    $oc_sql -u root -p$oc_rpwd -e "create database owncloud; grant all privileges on owncloud.* to 'oc_admin'@'localhost' identified by '$oc_upwd';"

  8. Disable maintenance mode: 

    sudo -u $oc_usr $oc_php $oc_occ maintenance:mode --off

  9. Perform the database conversion:

For DSM 6: 

sudo -u $oc_usr $oc_php $oc_occ db:convert-type --port=3307 --password=$oc_upwd --all-apps mysql oc_admin 127.0.0.1 owncloud

For DSM 7: 

sudo -u $oc_usr $oc_php $oc_occ db:convert-type --password=$oc_upwd --all-apps mysql oc_admin 127.0.0.1 owncloud

  1. Continue with memory caching and file locking configuration: 

    sudo -u $oc_usr $oc_php $oc_occ config:system:set memcache.local --value="\OC\Memcache\APCu"
sudo -u $oc_usr $oc_php $oc_occ config:system:set memcache.locking --value="\OC\Memcache\Redis"
sudo -u $oc_usr $oc_php $oc_occ config:system:set filelocking.enabled --value true

  2. Set up background jobs: 

    sudo -u $oc_usr $oc_php $oc_occ system:cron
