Following software / packages we will be using for this setup, ideal for a personal cloud on Raspberry Pi:

•     ownCloud 7.0.3
•     Nginx
•     OpenSSL
•     php 5
•     Raspbian Wheezy

1. Tuning up the Raspberry Pi
Following changes needs to be made under Raspberry Pi configuration
sudo raspi-config

a. Expand the root filesystem to have enough space for the cloud
    Select "Expand Filesystem"

b. Change locale to en_US.UTF8
    Select "Internationalisation  Options"

c. Memory split, allocate 16M to video graphics
    Select "Advanced Options" --> "Memory Split"

d. Overclock to Modest or Medium
    Select "Overclock"

2. Updating the package lists on Raspberry Pi
  sudo apt-get update
    sudo apt-get upgrade

3. Creating users Raspbian might already have is user & group
    sudo groupadd www-data
    sudo usermod -a -G www-data www-data

4. Installing the packages
    sudo apt-get install nginx openssl ssl-cert php5-cli php5-sqlite php5-gd php5-common php5-cgi sqlite3 php-pear php-apc curl libapr1 libtool curl libcurl4-openssl-dev php-xml-parser php5 php5-dev php5-gd php5-fpm memcached php5-memcache varnish


5. Make sure php5-curl is not installed
    sudo apt-get --purge remove php5-curl

6. Creating your SSL certificates for 2 years
    sudo openssl req $@ -new -x509 -days 730 -nodes -out /etc/nginx/cert.pem -keyout /etc/nginx/cert.key

    sudo chmod 600 /etc/nginx/cert.pem
    sudo chmod 600 /etc/nginx/cert.key

7. Configuring Ngnix web server replace entire file
    sudo nano /etc/nginx/sites-available/default


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

server {
        listen 80;
        server_name yourIPaddress;
        return 301 https://$server_name$request_uri;  # enforce https
}

server {
        listen 443 ssl;
        server_name yourIPaddress;

        ssl_certificate /etc/nginx/cert.pem;
        ssl_certificate_key /etc/nginx/cert.key;

        # Path to the root of your installation
        root /var/www/owncloud;

        client_max_body_size 1000M; # set max upload size
        fastcgi_buffers 64 4K;

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

        index index.php;
        error_page 403 /core/templates/403.php;
        error_page 404 /core/templates/404.php;

        location = /robots.txt {
            allow all;
            log_not_found off;
            access_log off;
        }

        location ~ ^/(?:\.htaccess|data|config|db_structure\.xml|README) {
                deny all;
        }

        location / {
                # The following 2 rules are only needed with webfinger
                rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
                rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;

                rewrite ^/.well-known/carddav /remote.php/carddav/ redirect;
                rewrite ^/.well-known/caldav /remote.php/caldav/ redirect;

                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)$ {

                # Optional: Don't log access to assets
                access_log off;
        }

}


8. Configuring max upload limit in php
    sudo nano /etc/php5/fpm/php.ini

    Tip: Use ctrl+w to search below lines and update:
    upload_max_filesize = 1000M
    post_max_size = 1000M

9. Configuring PHP
    sudo nano /etc/php5/fpm/pool.d/www.conf
    Change the following line from:
    listen = /var/run/php5-fpm.sock
    to
    listen = 127.0.0.1:9000

    sudo nano /etc/dphys-swapfile
    Change the following line from:
    CONF_SWAPSIZE=100
    to
    CONF_SWAPSIZE=512

10. Restart web server and Php
    sudo /etc/init.d/php5-fpm restart
    sudo /etc/init.d/nginx restart

11. Install ownCloud version 7.0.3 used here
    sudo mkdir -p /var/www/owncloud
    sudo wget https://download.owncloud.org/community/owncloud-7.0.3.tar.bz2
    sudo tar xvf owncloud-7.0.3.tar.bz2
    sudo mv owncloud/ /var/www/
    sudo chown -R www-data:www-data /var/www
