This tutorial provides an approach on how to set up Secure Sockets Layer (SSL) communication cryptographic protocol on Apache Web Server installed in Red Hat Enterprise Linux/CentOS 7.0, and generate self-signed Certificates and Keys with the help of a bash script which greatly simplifies the entire process.

Is there is a tool that can provide me a maximum of information (such as cpu, disk I/O, network, nfsd, memory and more) about my Linux/Unix server in a minimum of space in a terminal?

Say hello to Glances

From the project home page:

Glances is a free (LGPL) cross-platform curses-based monitoring tool which aims to present a maximum of information in a minimum of space, ideally to fit in a classical 80×24 terminal or higher to have additionnal information. Glances can adapt dynamically the displayed information depending on the terminal size. It can also work in a client/server mode for remote monitoring.
