Installation Manual

Install and Upgrade Manual

Supported distribution is Debian Wheezy (7.x).

Configuration of system

Configure FQDN on Debian

• if FQDN is defined, the host has to be visible from external network, (e.g. if FQDN is odn.example.com then the host must be visible both through http and https protocols via http://odn.example.com and https://odn.example.com)
• if FQDN is not defined, the host has to be visible from external network, (e.g. if hostname is example then the host must be visible both through http and https via http://example and https://example)

Steps to configure FQDN

1. to get ip address of host 
   IP_ADDRESS=`/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'`
2. to set FQDN - where host is accessible via my-computer.my-domain.ext 
   echo "$IP_ADDRESS my-computer.my-domain.ext my-computer " >> /etc/hosts
3. to verify if host is set properly 
   hostname -A

Configuration of java for tomcat

tomcat 7 uses by default java 6 so it is necessary to change default java for tomcat. Edit /etc/default/tomcat7, update environment variable JAVA_HOME. JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64

Installation on clean system

To install packages from COMSODE Debian repository, please follow these steps:

1. Add ODN packages repository into apt-sources-list: 
   echo "deb http://packages.comsode.eu/debian/ wheezy main" > /etc/apt/sources.list.d/odn.list

2. Add ODN public key: 
   wget -O - http://packages.comsode.eu/key/odn.gpg.key | apt-key add -

3. Update apt sources: 
   aptitude update

4. install ODN box (odn-simple package): 
   aptitude install odn-simple 
   The following user input is required during the installation process:

   • ldap password: whatever password can be used
   • Virtuoso password: dba

Note 1: If you want to reduce packages that are not necessary, then call 
aptitude install --without-recommends odn-simple

Note 2: In case of fresh clean Debian Wheezy installation the steps described above should work, no other commands are required. However in some cases some python dependency problems has been detected (when the Debian environment was created as a result of virtualization). In such cases the following steps are required to resolve the dependency problems:

apt-get purge python\*
apt-get install python2.7-minimal  -V
apt-get install libapache2-mod-wsgi -V
apt-get install lsb-release  -V
apt-get install python-pkg-resources  -V
apt-get install python-pip  -V
apt-get install python-setuptools  -V
aptitude install odn-simple -V

Upgrade from a previous version

Note:  Upgrade from ODN prior to 1.0.0 is not correctly supported due to change of CKAN version and also infrastructure changes.

If you already installed ODN using steps described in previous section, follow these steps

1. it is strongly recommended to backup databases
2. to update to newest version, simply run:

aptitude update
aptitude upgrade

User is required to confirm replacement of configuration files from previous installation, it should be confirmed by pressing 'Y' each time user input is required.
