ownCloud is WedDAV-based solution for storing and sharing on-line your data, files, images, video, music, calendars and contacts. You can have your ownCloud instance up and running in 5 minutes with Alpine!

Installation

ownCloud is available from Alpine 2.5 and greater.

Before you start installing anything, make sure you have latest packages available. Make sure you are using a 'http' repository in your /etc/apk/repositories and then run:

apk update

Tip: Detailed information is found in this doc.

Database

First you have to decide which database to use. Follow one of the below database alternatives.

sqlite

All you need to do is to install the package

apk add owncloud-sqlite

Warning: sqlite+owncould is known to have some problem, so do not expect it work. This note should be removed when sqlite+owncould works.
(Still a problem at 2012-11-15)

postgresql

Install the package

apk add owncloud-psql

Next thing is to configure and start the database

/etc/init.d/postgresql setup /etc/init.d/postgresql start

Next you need to create a user, database and set permissions.

# psql -U postgres postgres=# CREATE USER owncloud WITH PASSWORD '<%STRONG_PASSWORD%>'; postgres=# CREATE DATABASE owncloud; postgres=# GRANT ALL ON DATABASE owncloud TO owncloud; postgres=# \q

Note: The above commands creates the user 'owncloud' with a password you provide and the database 'owncloud'. Remember these settings, you will need them later when setting up owncloud

mysql

Install the package

apk add owncloud-mysql

Now configure and start mysql

/etc/init.d/mysql setup /etc/init.d/mysql start /usr/bin/mysql_secure_installation

Follow the wizard to setup passwords etc.

Webserver

Next thing is to choose, install and configure a webserver. Choose one alternative from below (or setup a webserver of your choise)

lighttpd

Install the package

apk add lighttpd

Make sure you have FastCGI enabled in lighttpd:

Contents of /etc/lighttpd/lighttpd.conf

...
include "mod_fastcgi.conf"
...

Start up the webserver

/etc/init.d/lighttpd start

XYZ webserver

You could try installing some other webserver and document it here

Apache2
cherokee
other...

Other

Link owncloud installation to web server directory:

ln -s /usr/share/webapps/owncloud /var/www/localhost/htdocs/owncloud

Other settings

Hardening

Consider adding the following line for additional security to the owncloud configuration file, where the password database is stored:

Contents of /etc/lighttpd/lighttpd.conf

...
url.access-deny = ("config.php")
...

Folder permissions

The web server user needs to have ownership on some dirs. This is fixed by running the following commands:

chown -R lighttpd.lighttpd /etc/owncloud chown -R lighttpd.lighttpd /usr/share/webapps/owncloud/apps chown -R lighttpd.lighttpd /var/lib/owncloud/data

Additional packages

Some large apps, such as texteditor and videoviewer are in separate package:

apk add owncloud-texteditor owncloud-videoviewer

Configure and use ownCloud

Configure

Point your browser at http://<%MY_SERVER_IP%>/owncloud and follow the on-screen instructions to complete the installation, supplying the database user and password created before.

Clients
