When a visitor accesses a website, a request is made to the web server for a specific kind of data. An example might be a home page of a site. Next, the web server locates that data and delivers it to the client who is requesting that data – basically back to the web browser.

This guide will walk you through the steps to create a Certificate Signing Request, (CSR for short.) SSL certificates are the industry-standard means of securing web traffic to and from your server, and the first step to getting your own SSL is to generate a CSR. This guide is written specifically for CentOS 7.

Node.js is a cross-platform runtime environment, configurable on Linux, OS X, and Microsoft Windows, and built on JavaScript. Applications, both server-side and networking, are also written in JavaScript. Node.js lends itself nicely to quick deploying, real-time web applications, and is generally thought of as extremely scalable due to its event-driven architecture.

The Node Version Manager allows admins to easily manage node.js versions. It’s a bash script that has the capability to manage multiple active versions of node.js, with functionality such as installation, executing commands with specific node.js versions, setting the PATH variable to use a specific node.js versions, etc.

Memcached is a distributed, high-performance, in-memory caching system that is primarily used to speed up sites that make heavy use of databases. It can, however, be used to store objects of any kind. Nearly every popular CMS has a plugin or module to take advantage of Memcached, and many programming languages have a Memcached library, including PHP, Perl, Ruby, and Python. Memcached runs in memory and is thus quite speedy since it does not need to write data to disk.
