We will share the contents of the folder to all the other nodes (physically stored on the master sudo apt-get install nfs-kernel-server echo '/mirror *(rw,sync,no_subtree_check)' | sudo tee -a sudo service nfs-kernel-server restart Make a folder in all nodes, where we will store our data and executables sudo mkdir /mirror This folder will be used to distribute the compiled executables over the nodes so that they can execute your program. NFS is used to create a distributed file system which is synchronized over the network. It is also possible to enter commands directly to a certain terminal or use CSSH's menu to select a subset. You can then issue text into the main CSSH text form to transmit it directly to all the slaves and see the results in their corresponding windows. This command will start 4 terminals and scale and position their windows automatically to fit your screen. Using it is cssh slave0 slave1 slave2 slave3 This program will need a graphical interface, if you install it on the master be sure to use the -XВ flag when connecting with sudo apt-get install clusterssh Of course, since repeating the same terminal commands isn't all that fun, there is a tool available which simplifies this: ClusterSSH. Preparing and managing your cluster will lead you into the situation where you have to manually configure several servers in the same way. Maybe you have to apply some changes to reflect your individual networking situation.ДЄfter that, install the DHCP server sudo apt-get install dnsmasqД®nsure that they are all in the same address range (in this example 10.0.0.x) and that there is only one 127.0.0.1 entry.Д¬luster SSH (optional, on workstation or master) Up /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE Up /sbin/iptables -A FORWARD -m conntrack -ctstate ESTABLISHED,RELATED -j ACCEPT Up /sbin/iptables -A FORWARD -o eth0 -i eth1 -s 10.0.0.0/24 -m conntrack -ctstate NEW -j ACCEPT # Setup firewall so to permit internet access of the slaves through the master (router sonfiguration)
