Installation and Upgrade Manual

• Supported distribution is Debian Wheezy (7.x)
• Ports to be opened: HTTP (80), HTTPS (443)

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 set FQDN - where host is accessible via my-computer.my-domain.ext 
2. add this line at the beginning of /etc/hosts: "127.0.1.1 my-computer.my-domain.ext my-computer "
3. to verify if host is set properly 
   hostname -f

(have look at https://greenmang0.wordpress.com/2009/02/25/how-to-set-fqdn-fully-qualified-domain-name-on-debian-system/)

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

Post-installation steps

perform the following steps immediately after the installation is done:

1. https://hostname/midpoint/login
   1. Username: administrator
   2. Password: 5ecr3t (please, do not forget to change this password in the upper-right corner while you are logged in)
2. in the Users menu of ODN/MP create new user(s) (you can define an organization for every new user - it will be created), create at least one user with Administrator role

Use this procedure for user creation only for the first time after installation. Later any user you have created with Administrator role is capable to create new users in ODN (use User management in Tools combo box).
