Owncloud¶

Owncloud has issues with .DS_Store files. At first I thought it was a Dropbox <-> Owncloud error, but then I turned off my Dropbox and was still getting the error. We need to figure out a way to have Owncloud exclude syncing .DS_Store files, or else it will generate a bunch of them. I don't know why it is doing so, but I have figured out how to delete them all:

Run this in the top of the Owncloud directory.

find ./ -type f -name ".DS_Stor*" -exec rm {} \;

Owncloud Installation¶

Owncloud 8.1 on Debian 7 with Apache¶

Wheezy does not have Owncloud 7 or 8 in repository (Jessie has 7.0 but I highly recommend using 8 for webUI improvements and speed)
Add the OpenSuse owncloud repository (this is maintained by owncloud devs)
After adding sudo apt-get update && sudo apt-get install owncloud
This should install owncloud to /var/www/owncloud, php, and mySQL
This will also create a conf file in /etc/apache2/conf.d/owncloud.conf which adds configuration redirects domain.com/owncloud to the owncloud directory.

contents of the conf file.

Alias /owncloud "/var/www/owncloud/" 
<Directory "/var/www/owncloud">
    Options +FollowSymLinks
    AllowOverride All
    Satisfy Any
    <IfModule mod_dav.c>
      Dav off
    </IfModule>

    SetEnv HOME /var/www/owncloud
    SetEnv HTTP_HOME /var/www/owncloud
</Directory>

<Directory "/var/www/owncloud/data/">
  # just in case if .htaccess gets disabled
  Require all denied
</Directory>

Set up Apache for owncloud access: For simple setups, edit the default-ssl config to point to ssl certs and enable with a2enmod default-ssl.
restart apache
go to https://domain.com/owncloud to start owncloud setup wizard.
If changes need to be made after first time setup either run again from Apps or edit /var/www/owncloud/config/config.php by hand

Database setup (mySQL)¶

make sure package php5-mysql is installed on system
start mysql command line mode mysql -uroot -p

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
CREATE DATABASE IF NOT EXISTS owncloud;
GRANT ALL PRIVILEGES ON owncloud.* TO 'username'@'localhost' IDENTIFIED BY 'password';

keep track of username and password as the owncloud setup wizard will need that.

Enabling Samba external users¶

Enable external_user and external_storage apps (lefthand tab menu--->apps---->not enabled. enable them)

for a local samba installation add the following to config.php

"user_backends" => array (
    0 => array (
            "class"     => "OC_User_SMB",
            "arguments" => array (
                              0 => 'localhost'
                              ),
    ),
),

users logging in with samba user and password should autocreate a user in owncloud. Permissions are not carried over!

Samba External Storage¶

go to owncloud admin panel after enabling external_storage
add share via interface.

owncloud + nginx¶

Install php5-fpm and nginx with apt-get install php5-fpm nginx
Uncomment "env[PATH] = /usr/local/bin:/usr/bin:/bin" in the file "/etc/php5/fpm/pool.d/www.conf"

owncloud provides a fairly good base nginx site file to use for simple setups. copied below.

upstream php-handler {
  #server 127.0.0.1:9000;
  server unix:/var/run/php5-fpm.sock;
  }

server {
  listen 80;
  server_name cloud.example.com;
  # enforce https
  return 301 https://$server_name$request_uri;
  }

server {
  listen 443 ssl;
  server_name cloud.example.com;

  ssl_certificate /etc/ssl/nginx/cloud.example.com.crt;
  ssl_certificate_key /etc/ssl/nginx/cloud.example.com.key;

  # Path to the root of your installation
  root /var/www/owncloud/;
  # set max upload size
  client_max_body_size 10G;
  fastcgi_buffers 64 4K;

  # Disable gzip to avoid the removal of the ETag header
  gzip off;

  # Uncomment if your server is build with the ngx_pagespeed module
  # This module is currently not supported.
  #pagespeed off;

  rewrite ^/caldav(.*)$ /remote.php/caldav$1 redirect;

    access_log off;
    }

   rewrite ^(/core/doc/[^\/]+/)$ $1/index.html;

   try_files $uri $uri/ /index.php;
   }

   location ~ \.php(?:$|/) {
   fastcgi_split_path_info ^(.+\.php)(/.+)$;
   include fastcgi_params;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   fastcgi_param PATH_INFO $fastcgi_path_info;
   fastcgi_param HTTPS on;
   fastcgi_pass php-handler;
   }

   # Optional: set long EXPIRES header on static assets
   location ~* \.(?:jpg|jpeg|gif|bmp|ico|png|css|js|swf)$ {
       expires 30d;
       # Optional: Don't log access to assets
         access_log off;
   }

  }

In the main server block add add_header Strict-Transport-Security "max-age=31536000; includeSubdomains"; to enable strict transport security

Performance tweaks¶

*coming soon: enabling apc (or apcu in php5.5 or later), php.ini edits, server edits.

Security and Hardening¶

enable mod_headers (a2enmod headers) and add Header always add Strict-Transport-Security "max-age=15768000" to virtual host file.
move data directory outside /var/www/owncloud folder
turn on server side encryption of data. (Admin settings --> turn on)

redirect all traffic to ssl:

<VirtualHost *:80>
   ServerName cloud.owncloud.com
   Redirect permanent / https://cloud.owncloud.com/
</VirtualHost>
