OwnCloud

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-pgsql

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, and temporary grant CREATEDB privilege.

psql -U postgres CREATE USER mycloud WITH PASSWORD 'test123'; ALTER ROLE mycloud CREATEDB; \q

Note: Replace the above username 'mycloud' and password 'test123' to something secure. Remember these settings, you will need them later when setting up owncloud.

mysql

Install the package

apk add owncloud-mysql mysql-client

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.

Note: Remember the usernames/passwords that you set using the wizard, you will need them later.

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

mysql -u root -p CREATE DATABASE owncloud; GRANT ALL ON owncloud.* TO 'mycloud'@'localhost' IDENTIFIED BY 'test123'; GRANT ALL ON owncloud.* TO 'mycloud'@'localhost.localdomain' IDENTIFIED BY 'test123'; FLUSH PRIVILEGES; EXIT

Note: Replace the above username 'mycloud' and password 'test123' to something secure. Remember these settings, you will need them later when setting up owncloud.

mysql-client is not needed anymore. Let's uninstall it:

apk del mysql-client

Webserver

Next thing is to choose, install and configure a webserver. In this example we will install lighttpd but you are free to install any other webserver of your choise as long as it supports php and FastCGI.

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

Tip: You might want to follow the Lighttpd_Https_access doc in order to configure lighttpd to use https (securing your connections to your owncloud server).

Publish owncloud

Link owncloud installation to web server directory:

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

Other settings

Hardening

Consider updating the variable url.access-deny in /etc/lighttpd/lighttpd.conf for additional security. Add "config.php" to the variable (that's where the database is stored) so it looks something like this:

Contents of /etc/lighttpd/lighttpd.conf

... url.access-deny = ("~", ".inc", "config.php") ...

Restart lighttpd to activate the changes

/etc/init.d/lighttpd restart

Additional packages

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

apk add owncloud-texteditor owncloud-videoviewer

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

Note: Each time you upgrade owncloud you need to remember to fix the permissions as described above.

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.

Hardening postgresql

If you have chosen PGSQL backend, revoke CREATEDB privilege from 'mycloud' user:

psql -U postgres ALTER ROLE mycloud NOCREATEDB; \q

Increase upload size

Default configuration for php is limited to 2Mb file size. You might want to increase that size by editing the /etc/php/php.ini and change the following values to something that suits you:

upload_max_filesize = 2M
post_max_size = 8M

Clients

There are clients available for many platforms, Android included:
