This repository helps you to set up a minimum YADT installation.

Try it yourself ...

... using the yadtshell it's easy to start and stop services on yadtclients.

In this guide we want to show you how to set up a minimal YADT system, on a single host with dummy services to play with.

Prerequisites

• We recommend to test YADT in a vm.
• red hat system version 6.x (preferred).
• python >= 2.6.
• yum, rpm and a user with sufficient rights to install/remove packages via sudo yum.
• All hosts to be controlled are accessible passwordless via ssh.
• EPEL has to be installed. You will find the rpm on The newest version of 'epel-release' for EL6, for example

sudo yum localinstall http://ftp.tu-chemnitz.de/pub/linux/fedora-epel/6/i386/epel-release-6-8.noarch.rpm

• git to clone the repository

sudo yum install git

Checkout the files

Clone the try-it-yourself repository:

git clone https://github.com/yadt/try-it-yourself

Installation

Password-less ssh on local machine

# keep the .ssh path but set the passphrase as you like
ssh-keygen
# copy the id_rsa.pub key to the authorized_key file in your .ssh folder (home directory)
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

Execute setup scripts

cd try-it-yourself

( cd yadtclient; ./setup.sh )

( cd yadtshell; ./setup.sh )

The yum installation runs will ask you if you want to proceed: review the actions yum will take and type yes when appropriate.

"Hello World"

cd yadtshell
./helloworld.sh

This script will

1. create a simple target definition file in a new subfolder adequately named "helloworld",
2. define the local host as member of the new target (using its fqdn),
3. update the target and start all services,
4. try to fetch the current status information of the target via yadtshell status

For more commands, check out the cheat sheet from the project page or the wiki.

Deinstallation

To remove all yadt related rpms, run ./cleanup.sh in both the yadtclient and yadtshell folder.
