Setting up Development Environment with Vagrant

In this tutorial, we will demonstrate how to install Vagrant on multiple operating systems.

Introduction

In this article we will learn what the Network Time protocol (NTP) is and how to install it on the two Linux distributions most commonly used on Liquid Web’s servers. We will be focusing on using CentOS 7 and Ubuntu 18.04 servers, but the process is largely the same on other recent versions of each. Before we start, make sure we are familiar with using SSH (Secure Shell) as we’ll need it to connect to the server. Here’s a link to one of our articles on the basics of SSH if you are unfamiliar with its usage.

Keras is a Python-based high-level neural networks API that is capable of running on top TensorFlow, CNTK, or Theano frameworks used for machine learning. It can be said that Keras acts as the Python Deep Learning Library. Keras was created with emphasis on being user-friendly since the main principle behind it is “designed for human beings, not machines.” The core data structure of Keras is a model, or a way to organize layers.

• These instructions are intended specifically for listing the existing compiled PHP modules from the command line.
• Your server environment may be different, but we will go over several options that you might run into. We'll be using an Ubuntu Server with only a single PHP version on it, and two CentOS 7 servers, one with cPanel and one with InterWorx.

Single PHP Version

If your server only has a single PHP version installed, you can run this PHP command anywhere, and it will give you the same list of modules. The general command we will be using is php -m. This command will give you the full list of installed PHP modules/extensions.

Today we’re going to install Ruby on Rails using RVM (the Ruby Version Manager) onto a CentOS 8 server. Let's start by defining a few terms and definitions we will be using during the process.

Introduction

Configuring a single server with the required software is a reasonably simple task. However, if numerous servers need to have the same or similar software and configurations installed on them, the process would use numerous man-hours to complete, which would deplete your already strained resources. Without some form of automation, this task can become nearly insurmountable. With this task in mind, new configuration management tools were developed to address the need to deploy new servers with premade configurations and updates, that allowed for a smoother and more manageable automation process. To keep these servers syncing and to manage updates across a broad swath of hosts in a data center or cloud environment, automation tools like Puppet, SaltStack, Chef, and Ansible meet this need.

In this tutorial, we will learn how to install the latest kernel version on multiple Linux distributions. 

In this tutorial, we will consider how to enable both Python 2 and Python 3 for use on CentOS 8. In earlier distributions of CentOS, an unversioned Python command was available by default. 

What is Tomcat?

In this article, we will be demonstrating how to install Apache Tomcat on CentOS 8. Before we begin, let's define exactly what Apache Tomcat is. Apache defines Tomcat as: "An open-source, servlet container, JavaServer Pages, Java Expression Language, and WebSocket technology that also acts as a web server. It affords a "pure Java" based HTTP server environment in which Java can be executed." Tomcat works with the Java programming language and is associated with web applications written in Java.

Python is a general-purpose programming language designed for various uses. For example, websites, industrial robotics, and even games all use the same core technology.
