In Conclusion

This chapter has introduced you to the Linux Enterprise Cluster from the perspective of the services that will run inside it, on the cluster nodes. The normal method of starting daemons when a system boots on a Linux system using init scripts^[13] is also used to start the daemons that will run inside the cluster. The init scripts that come with your distribution can be used on the cluster nodes to start the services you would like to offer to your users. A key feature of a Linux Enterprise Cluster is that all of the cluster nodes run the same services; all nodes inside it are the same (except for their network IP address).

In Chapter 2 I lay the foundation for understanding the Linux Enterprise Cluster from the perspective of the network packets that will be used in the cluster, and in the Linux kernel that will sit in front of the cluster.
