LiveQ is a job distribution and monitoring framework with real-time feedback, control and full network awareness. The framework is modular and designed to be fully scalable.

Installing the LiveQ Framework in order to run for the Virtual Atom Smasher game is a quite complicated process through many steps. Please make sure you follow these steps in order otherwise you might have trouble running the components.

You will need to have the following services running in your system (locally or in your cluster):

• RabbitMQ
• ejabberd
• Redis
• MySQL

In addition, on the machines that you will run the liveq-webserver component, you will need:

• Apache (or any other webserver)

You will also need to prepare the services for use by a LiveQ:

• Create two accounts on the ejabberd server, one for the agents and one for the managers:

ejabberctl register liveq_agent <hostname> <secret>
ejabberctl register liveq_manager <hostname> <secret>

• Create two databases on the MySQL server, one for the LiveQ framework (ex. liveq) and one for the MyBB forum that will be embedded in the game interface (ex. mybb).
• Create two users on the MySQL server and grant them all priviledges on the two databases.

On the machines that you are going to run a LiveQ agent you are going to need the following software installed:

• Python >= 2.7
• virtualenv
• pip

First, you need to check-out the latest version of LiveQ from github:

git clone https://github.com/wavesoft/LiveQ
cd LiveQ

Then you will need to create a directory were to keep the reference histograms and the simulation results:

mkdir -p data.local/{ref,results}

Extract the reference data:

cd data.local/ref
tar -jxf ../../schema/ref-data.tbz2

Finally, you will need to configure the component you want to use.

Copy liveq-jobmanager/config/jobmanager.conf to liveq-jobmanager/config/jobmanager.conf.local and edit to match your needs:

loglevel=info

sendmail=			# << Full path to the 'sendmail' binary in your system

That's perhaps the most important component of all, since it allows you to check the status of the system. Like before, you will need to copy tools/config/common.conf to tools/config/common.conf.local and edit like before.

The sections are already explained before, so just copy them.

There is a bootstrap utility that takes care of setting up the environment and running the component. You can use it for example like this: ]

./bootstrap.sh admin installdb

A few moments later your database should be installed and ready to use!

There is a bootstrap utility that takes care of setting up the environment and running the component. You can use it for example like this:

./bootstrap.sh liveq-webserver
