ownCloud is a software suite that provides a location-independent storage area for data (cloud storage).

Installation

owncloudAUR is available in the AUR.

  1. First of all set up the LAMP stack as described in the corresponding Wiki article.
  2. Install the owncloudAUR package as described in AUR#Installing_packages.
  3. Add the following lines into /etc/httpd/conf/httpd.conf (php5 should have been configured during the LAMP stack setup):
 Include /etc/httpd/conf/extra/owncloud.conf
 LoadModule php5_module modules/libphp5.so
 Include conf/extra/php5_module.conf

Uncomment extensions in /etc/php/php.ini

 gd.so
 xmlrpc.so
 zip.so
 iconv.so

Depending on which database backend you are going to use uncomment either one of the following extensions in /etc/php/php.ini

 sqlite.so
 sqlite3.so
 pdo_sqlite.so

OR

 mysql.so
 mysqli.so
 pdo_mysql.so

now restart httpd (Apache) and open http://localhost in your browser. You should now be able to create a user account and follow the installation wizard.

Custom configurations

Filesize Limitations

With the default configuration ownCloud only allows the upload of filesizes less than 2MB. This can be changed by changing the following line in /etc/php/php.ini to your liking.

As of version 4.0 this is no longer necessary! The maximum upload size is now set via the ownCloud gui

 upload_max_filesize = 2M

As of version 4.5, upload limits are set in /usr/share/webapps/owncloud/.htaccess. This won't work if PHP is set up to run as CGI, so you need to change the limits in /etc/php/php.ini. You also need to change open_basedir.

 upload_max_filesize = 512M
 post_max_size = 512M
 memory_limit = 512M
 open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/

Running owncloud in a subdirectory

By including the default owncloud.conf in httpd.conf, owncloud will take control of port 80 and your localhost domain. If you would like to have owncloud run in a subdirectory, then skip the 'Include /etc/httpd/conf/extra/owncloud.conf' line altogether and just use a symbolic link like so:

ln -s /usr/share/webapps/owncloud/ /srv/http/

Filling ownCloud with data

Small Files

Always use WebDAV or the web interface to add new files to your ownCloud. Otherwise they will not show up correctly, as they do not get indexed right.

Consider installing and enabling php-apc to speed up WebDAV.

When using SABnzbd, you might want to set

folder_rename 0

in your sabnzbd.ini file, because ownCloud will scan the files as soon as they get uploaded, preventing SABnzbd from removing UNPACKING prefixes etc.

Big Files

WebDAV isn't suitable for big files, because it fills up all the RAM and CPU.

With the current version, it looks like, there is no good way of copying huge amounts of data to your ownCloud.


Here's a Workaround:

copy the files directly to your ownCloud and do a full re-scan of your database (you could use the Re-scan filesystem add-on for example).


But beware that this will not work as easily in the future, when end-to-end encryption gets added to ownCloud (this is a planned feature).

Important Notes

  • When using a subdomain (like cloud.example.xxx), make sure it is covered by your certificate. Otherwise, connection via the owncloud client or webdav might fail.
  • If you are planning on using OwnCloud's sync-clients, make sure to have NTP installed and running on your OwnCloud server, otherwise the sync-clients will fail.

Nginx + uwsgi_php alternative

You can avoid the use of Apache, and run owncloud in it's own process by using the wsgi_php application server. uWSGI itself has a wealth of features to limit the resource use, and to harden the security of the application, and by being a separate process it can run under its own user.

The nginx config is:

#this is to avoid Request Entity Too Large error
client_max_body_size 1000M;
# deny access to some special files
location ~ ^/(data|config|\.ht|db_structure\.xml|README) {
    deny all;
}
# pass all .php or .php/path urls to uWSGI
location ~ ^(.+\.php)(.*)$ {
    include uwsgi_params;
    uwsgi_modifier1 14;
    uwsgi_pass 127.0.0.1:3001;
}
# everything else goes to the filesystem,
# but / will be mapped to index.php and run through uwsgi
location / {
    root /usr/share/webapps/owncloud;
    index index.php;
}

The uWSGI /etc/uwsgi/owncloud.ini config file (run it with uwsgi_php --ini /etc/uwsgi/owncloud.ini):

[uwsgi]
socket = 127.0.0.1:3001
master = true
chdir = /srv/http/owncloud
php-docroot = /usr/share/webapps/owncloud
php-index = index.php

# only allow these php files, I don't want to inadvertently run something else
php-allowed-ext = /index.php
php-allowed-ext = /remote.php
php-allowed-ext = /cron.php
php-allowed-ext = /status.php
php-allowed-ext = /settings/apps.php
php-allowed-ext = /core/ajax/share.php
php-allowed-ext = /core/ajax/requesttoken.php
php-allowed-ext = /core/ajax/translations.php
php-allowed-ext = /search/ajax/search.php
php-allowed-ext = /search/templates/part.results.php
php-allowed-ext = /settings/admin.php
php-allowed-ext = /settings/users.php
php-allowed-ext = /settings/personal.php
php-allowed-ext = /settings/help.php
php-allowed-ext = /settings/ajax/getlog.php
php-allowed-ext = /settings/ajax/setlanguage.php
php-allowed-ext = /settings/ajax/setquota.php
php-allowed-ext = /settings/ajax/userlist.php
php-allowed-ext = /settings/ajax/createuser.php
php-allowed-ext = /settings/ajax/removeuser.php
php-allowed-ext = /settings/ajax/enableapp.php
php-allowed-ext = /core/ajax/appconfig.php

php-set = date.timezone=Europe/Skopje
php-set = open_basedir=/srv/http/owncloud:/tmp/:/usr/share/pear/:/usr/share/webapps/owncloud

processes = 10
cheaper = 2

Finally, a simple systemd unit file to start the uwsgi instance can be (this is without using the emperor):

[Unit]
Description=OwnCloud service via uWSGI-PHP

[Service]
User=http
ExecStart=/usr/bin/uwsgi_php --ini /etc/uwsgi/owncloud.ini
ExecReload=/bin/kill -HUP $MAINPID
KillSignal=SIGQUIT
Restart=always

[Install]
WantedBy=multi-user.target
