ownCloud on Archlinux

After receiving a very unpleasant notice about the end of the copy.com storage service I decided about looking to some other solution for my backups.

I decided to also try ownCloud (version 8.2.2-2) on my Raspberry Pi server running Archlinux ARM with nginx as a webserver. It was a bit tricky and here is what I had to do. This guide is meant to be in the style get it up and running fast and dirty.

Installation

You need to install appropriate packages to make it work. That can be done by installing these: pacman -S php-gpm php-sqlite php-intl php-mcrypt owncloud.

Then you need to uncomment these in /etc/php/php.ini:

gd.so  
iconv.so  
xmlrpc.so  
zip.so  
bz2.so  
curl.so  
intl.so  
mcrypt.so  
pdo_sqlite.so  
sqlite3.so  

and also edit this line:

open_basedir = /var/www:/tmp/:/var/www/owncloud/:/usr/share/webapps/owncloud/:/etc/webapps/owncloud/  

then generate a certificates (thanks to this guy):

# become root
sudo -s  
cd /etc/ssl  
openssl genrsa 2048 > server.key  
# enter *.example.com for the Common Name
openssl req -new -x509 -nodes -sha1 -days 3650 -key server.key > server.crt  
openssl x509 -noout -fingerprint -text < server.crt > server.info  
cat server.crt server.key > server.pem  
chmod 400 server.key server.pem  

Configuration of nginx

For nginx configuration you will need to first generate certificates e.g. by the following (you need to change server_name and ssl_certificate* fields):

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 /path/to/domain-cert.crt;
  ssl_certificate_key /path/to/private-key.key;

  add_header X-Robots-Tag none;
  add_header X-Download-Options noopen;
  add_header X-Permitted-Cross-Domain-Policies none;

    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_param HTTPS on;
    fastcgi_param modHeadersAvailable true; #Avoid sending the security headers twice
    fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
    fastcgi_intercept_errors on;
  }

  # Adding the cache control header for js and css files
  # Make sure it is BELOW the location ~ \.php(?:$|/) { block
  location ~* \.(?:css|js)$ {
    add_header Cache-Control "public, max-age=7200";
    # Add headers to serve security related headers
    add_header Strict-Transport-Security "max-age=15768000; includeSubDomains; preload;";
    add_header X-Content-Type-Options nosniff;
    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Robots-Tag none;
    add_header X-Download-Options noopen;
    add_header X-Permitted-Cross-Domain-Policies none;
    # Optional: Don't log access to assets
    access_log off;
  }

  location ~ ^/var/www/owncloud/data {
      internal;
      root /;
    } 

  # Optional: Don't log access to other assets
  location ~* \.(?:jpg|jpeg|gif|bmp|ico|png|swf)$ {
    access_log off;
  }
}

and then you need to change an appropriate owners to all config directories including the installation one. Without doing that I wasn't able to make owncloud running. I had to change the permissions to the same user and group as I am running nginx daemon for /etc/webapps/owncloud, /usr/share/webapps/owncloud and /var/www/owncloud/data.

Then just restart nginx and php-fpm daemon (using systemctl). That should be enough.
