Ubuntu Cluster - Slave nodes
In this part we'll install and configure the other nodes, in the master node we have a DHCP server and a PXE network boot which serves the netboot system, so we just need to connect the net cable, a keyboard and a monitor to the node, turn on and wait to install the base system. Options include partition of the hda disk, we use the defaults and put all the system in a partition and default swap size. We add the general user named beagle and after rebooting, login, become root, change the password and install the SSH server: sudo su - passwd apt-get install openssh-server Repeat this for all the nodes. The next steps will be only from the master node. SSH access You need to create a pair of keys for each user to access any node without a password, first we create it in the general user beagle : ssh-keygen cp .ssh/id_pub .ssh/authorized_keys Root also need this keys, but we don't export the root's home, after you created the keys, you need to copy to all the nodes.
