The Raspberry and owncloud ran for a few months now and I really enjoyed my own personal cloud. But I was really annoyed by the poor performance. One possible solution was to switch the sd card, which I did. I replaced the Transcend 16GB SDHC card with a 4GB one. Performance is much better now. Since setting up the system is a pretty simple and fast process, I didn’t bother about cloning the card etc. I reinstalled raspbian and followed my own guide on how to setup nginx and php and oriented on my other tutorial on how to install owncloud 6 beta. Of course I needed to change some links etc.

Some more things (I) changed:

1. owncloud added security for trusted domains
2. moved owncloud storage to an external usb drive
3. changed the nginx webserver configuration: restrict to https only and …
4. accessing php-fpm through network socket

1. If you access the webinterface of your owncloud instance using different ips, names etc., you need to add them to the „trusted_domains“ parameter.

pi@raspberrypi ~ $ sudo vi /var/www/owncloud/config/config.php

‚trusted_domains‘ =>
array (
0 => ‚192.168.12.34′,
1 => ‚your.dyndns.org‚,
),

2. Connect the usb drive and use lsblk and blkid to find the needed UUID.

pi@raspberrypi ~ $ lsblk && blkid
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 2,7T 0 disk
└─sda1 8:1 0 2,7T 0 part /media/usb
mmcblk0 179:0 0 3,7G 0 disk
├─mmcblk0p1 179:1 0 56M 0 part /boot
└─mmcblk0p2 179:2 0 3,7G 0 part /
/dev/mmcblk0p1: SEC_TYPE=“msdos“ LABEL=“boot“ UUID=“7D5C-A285″ TYPE=“vfat“
/dev/mmcblk0p2: UUID=“5d18be51-3217-4679-9c72-a54e0fc53d6b“ TYPE=“ext4″
/dev/sda1: LABEL=“Backup3TB“ UUID=“1D3F163D4EEC069E“ TYPE=“ntfs“

Create the mountpoint /media/usb and edit /etc/fstab to mount the drive on startup.

pi@raspberrypi ~ $ sudo mkdir /media/usb

pi@raspberrypi ~ $ sudo vi /etc/fstab
proc /proc proc defaults 0 0
/dev/mmcblk0p1 /boot vfat defaults 0 2
/dev/mmcblk0p2 / ext4 defaults,noatime 0 1
UUID=1D3F163D4EEC069E /media/usb ntfs-3g defaults,auto, uid=pi,gid=wwwdata,umask=007,users 0 0

While setting up your owncloud, you can now define /media/usb as your data storage. Not sure if there is a way to change this on a already running owncloud setup.

3. Change the nginx configuration (/etc/nginx/sites-availabe/default) according to the owncloud 6 documentation

upstream php-handler {
server 127.0.0.1:9000;
}

server {
listen 80;
return 301 https://your.dyndns.org$request_uri; # enforce https
}

# HTTPS server
#
server {
listen 443 ssl;
server_name your.dyndns.org localhost;

root /var/www;

autoindex off;
index index.php index.html index.htm;

ssl on;
ssl_certificate /etc/nginx/conf.d/ssl/server.crt;
ssl_certificate_key /etc/nginx/conf.d/ssl/server.key;

client_max_body_size 10G; # set max upload size
fastcgi_buffers 64 4K;

}

location ~ ^(.+?\.php)(/.*)?$ {
try_files $1 =404;

include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$1;
fastcgi_param PATH_INFO $2;
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;
}
}

4. Modify the php5-fpm config to listen on a netsocket.

 pi@raspberrypi ~ $ sudo vi /etc/php5/fpm/pool.d/www.conf

;listen = /var/run/php5-fpm.sock
listen = 127.0.0.1:9000

Restart the services.

pi@raspberrypi ~ $ sudo service php5-fpm restart
pi@raspberrypi ~ $ sudo service nginx restart
