Preparations

It is assumed that root can login to a standard shell. Furthermore, it is assumed that the server is reachable via SSH. If it is not, install openssh-server as root:

apt-get update
apt-get install openssh-server

The following steps will reference installation scripts. These need to be downloaded, extracted and made executable. As root run:

wget https://github.com/chkgk/otree_setup_scripts/archive/master.zip
unzip master.zip
cd otree_setup_scripts-master
chmod +x setup_otree_server.sh

You are now ready for the first step of the installation.
