The following changes have been made to improve security of the cluster:

• Master is no longer accessible (all ports are closed)
• Once Slave node is registered with the Master, it stops responding to other requests

• Start all the Truven nodes
• Log in into the truven-master
• edit the slaves.dat file in /home/podalv so that it points to the slaves that need to be registered

curl http://localhost:8080/refresh_slave_list

• wait for the master to start and attach all slaves
• log out from master
• from your computer run:

ssh -L 8080:localhost:8080 your_name@35.203.160.79

Now, you can access Truven cluster on your machine using http://localhost:8080
