Status: Deprecated> Status: Deprecated # This article covers a version of CentOS that is no longer supported. If you are currently operating a server running CentOS 6, we highly recommend upgrading or migrating to a supported version of CentOS.

Introduction> Introduction # TLS, or transport layer security, and its predecessor SSL, which stands for secure sockets layer, are web protocols used to wrap normal traffic in a protected, encrypted wrapper.

What is Caching?> What is Caching? # Caching is a method of improving server performance by allowing commonly requested content to be temporarily stored in a way that allows for faster access.

Introduction> Introduction # A “LAMP” stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. This term is actually an acronym which represents the Linux operating system, with the Apache web server.

Introduction> Introduction # In this tutorial, we will activate and learn how to manage URL rewrites using Apache 2’s mod_rewrite module. This module allows us to rewrite URLs in a cleaner fashion, translating human-readable paths into code-friendly query strings or redirecting URLs based on additional conditions.

Introduction> Introduction # The Apache HTTP server is the most widely-used web server in the world. It provides many powerful features including dynamically loadable modules, robust media support, and extensive integration with other popular software.

Introduction> Introduction # Cassandra, or Apache Cassandra, is a highly scalable open source NoSQL database system, achieving great performance on multi-node setups. In this tutorial, you’ll learn how to install and use it to run a single-node cluster on Ubuntu 14.

Introduction> Introduction # WordPress is the most popular content management system (CMS) on the internet. It allows you to set up flexible blogs and websites on top of a MySQL backend with PHP processing.

Introduction> Introduction # WebDAV is an extension of the HTTP protocol that allows users to manage files on servers. There are many ways to use a WebDAV server. For example, you can share Word or Excel documents with your colleagues by uploading them to your WebDAV server.

Introduction> Introduction # A reverse proxy is a type of proxy server that takes HTTP(S) requests and transparently distributes them to one or more backend servers. Reverse proxies are useful because many modern web applications process incoming HTTP requests using backend application servers which aren’t meant to be accessed by users directly and often only support rudimentary HTTP features.

Introduction> Introduction # Let’s Encrypt is a Certificate Authority (CA) that provides free certificates for Transport Layer Security (TLS) encryption, thereby enabling encrypted HTTPS on web servers. It simplifies the process of creation, validation, signing, installation, and renewal of certificates by providing a software client that automates most of the steps—Certbot.

Introduction> Introduction # LDAP, or Lightweight Directory Access Protocol, is a protocol designed to manage and access related information in a centralized, hierarchical file and directory structure. In some ways, it operates similarly to a relational database, but this does not hold true for everything.

Introduction> Introduction # Apache Kafka is a popular distributed message broker designed to handle large volumes of real-time data efficiently. A Kafka cluster is not only highly scalable and fault-tolerant, but it also has a much higher throughput compared to other message brokers such as ActiveMQ and RabbitMQ.

Introduction> Introduction # Nextcloud, a fork of ownCloud, is a file sharing server that permits you to store your personal content, like documents and pictures, in a centralized location, much like Dropbox.

Prelude> Prelude # Mod security is a free Web Application Firewall (WAF) that works with Apache, Nginx and IIS.
