===== What is ownCloud =====

[[https://de.wikipedia.org/wiki/OwnCloud|Wikipedia - ownCloud]]

===== Installation =====

Get the tarball from the official Site [[https://owncloud.org/download/|ownCloud]]

<code>wget https://download.owncloud.org/community/owncloud-10.0.6.tar.bz2</code>

Extract
<code>tar -xzf owncloud-10.0.6.tar.bz2</code>

If you use Ubuntu 14.04 you might have PHP5.5 in use. You need PHP5.6 to run this version of Owncloud.\\
Check your current PHP5 modules
<code>dpkg -l |grep php5</code>
The following are needed by owncloud
<code>libapache2-mod-php5 php5-gd php5-json php5-mysql php5-curl php5-intl php5-mcrypt php5-imagick</code>
Install PHP5.6, just remove the php-modules that you dont need (I included all I have)
<code>
add-apt-repository ppa:ondrej/php
apt-get update
apt-get install php5.6 php5.6-mbstring php5.6-mcrypt php5.6-mysql php5.6-xml php5.6-apcu php5.6-zip php5.6-gd php5.6-curl php5.6-bcmath php5.6-intl php5.6-soap php5.6-imagick php5.6-imap php5.6-memcache php5.6-ps php5.6-pspell php5.6-recode php5.6-snmp php5.6-sqlite3 php5.6-tidy php5.6-xmlrpc php5.6-xsl
a2dismod php5
a2enmod php5.6
service apache2 restart
</code>

Copy the owncloud folder to your apache2 documentroot
<code>mv owncloud /var/www/</code>

Make sure your webuser is the owner of the dir and its files
<code>chown -R www-data:www-data /var/www/owncloud</code>

Add the following to an existing siteconfig or create a new one
<code>
Alias /owncloud "/var/www/owncloud/"

<Directory /var/www/owncloud/>
  Options +FollowSymlinks
  AllowOverride All

 <IfModule mod_dav.c>
  Dav off
 </IfModule>

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud

</Directory>
</code>

Activate the following apache2 modules

<code>
a2enmod rewrite
a2enmod headers
a2enmod env
a2enmod dir
a2enmod mime
service apache2 restart
</code>

Browse your site, enter your username and password, add the MySQL connection info and you are done.

===== Troubleshooting =====

==== Cant find the website ====

If you cant access your website (/owncloud was not found), you might need to change your documentroot from /var/www/html to /var/www or copy your owncloud folder into /var/www/html

==== HSTS: Header Strict Transport Security ====

Add the following to your .htaccess
<code>Header set Strict-Transport-Security "max-age=31536000"</code>

OR

Add the following to your apache2 siteconfig
<code>Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"</code>


==== No OneDrive as external storage visible ====

You might have found the doc which explains how to add OneDrive as external storage.
Welcome to ownCloud, this feature is enterprise only...

==== Files added via CLI are not visible ====

This is NOT recommended...

<code>The data directory on the server is exclusive to ownCloud and must not be modified manually.</code>

[[https://central.owncloud.org/t/why-does-my-files-i-put-into-datadir-dont-appear-in-owncloud/818|ownCloud FAQ - Solutions]]

Easiest solution is to add a "local external storage". BUT... this option has been disabled because of security...

Here is how to fix:

Add this to "/var/www/owncloud/config/config.php"
<code>'files_external_allow_create_new_local' => true,</code>

Follow this doc to add this "safely":\\
