This how to describes an easy step by step installation of the Red Hat Cluster Suite on 3 centos nodes and prepare them as nodes of a cluster. You will also install the Management suite which is web based and is known as Conga.

You will use 3 nodes to form the cluster and 1 node as the cluster management node and as a cluster node it will not take part. All the nodes and the management node should be resolvable either by host file entries or by DNS.

Linux System Auditing

Posted 01-04-2012 at 12:20 AM by sudhagud

The code and tar ball can be downloaded from both google code or from source forge website's and the project website has links to documentation, help, installation and code.

Suggestions are welcome. The script itself.

On a day to day work load, starting one with simple task to complex multiple tasks, IT System Administrators and all other personnel who look after the IT Data Centre and IT Infrastructure, sometimes find that they have to run a multiple command set, that to for simple information. In recent times the Desktop GUI and the relative backend tools that make the Linux System have advanced well, but for remote system administration, unlike Windows where RDT can be used, Sysadmin's prefer a shell and a...
