Setting up the perfect web-development environment using docker and ZOL - Techzim[9] I have to admit I am as far from winning the world?s best web-developer as it gets, but I give it my best. And also I mostly develop for myself apart from the very rare and little WordPress PHP snippets I have shared with my even more technologically inept friends. Recently though I found myself needing to put on that web-dev fedora for a project on one of my sites.With that being said, I was rusty and even finding the right local development environment was a struggle. Usually, I just use FlyWheel?s LocalWP and Atom. That works well for my much smaller WordPress customisation projects that never seem to go beyond a single page of code but this time it was a more complex project and the limits of LocalWP became quickly apparent. Changing your shell from bash to zsh and back ? any desktop | ArcoLinux[10] It all depends on the iso you start with Arch Linux, ArcoLinux, ArcoLinuxD or ArcoLinuxB.

  • XAMPP Web Development Stack
    XAMPP Web Development Stack Overview @author R.L. Martinez, Ph.D. The steps below outline the processes for installing the XAMPP stack on a local machine. The XAMPP (pronounced Zamp) stack includes the following: Apache HTTP Server, MariaDB (essentially MySQL), Database Server, Perl, and the PHP Interpreter. The “X” in XAMPP is used to signify the cross-platform compatibility of the stack. The Apache HTTP Server and PHP are required to run phpMyAdmin which is a PHP application that is used for database administration tasks such as creating databases and tables, adding users, etc. Alternative to XAMPP If you have experience with MySQL Workbench, you may prefer to install MySQL Server and MySQL Workbench via the MySQL Installer. MySQL Workbench performs the same functions as phpMyAdmin. However, unlike phpMyAdmin which is a web-based application, MySQL Workbench is a locally installed application and therefore does not require an HTTP Server (e.g. Apache) to run. Installing XAMPP Many of the steps listed have several alternatives (such as changing MySQL passwords via a command line) and students are welcomed and encouraged to explore alternatives. 1. Download XAMPP from the URL below and place the installer (.exe) in the location where you want to install XAMPP. Placing the installer (.exe) in the same location as the intended installation is not required but preferred. http://www.apachefriends.org/download.html Page 1 of 17 XAMPP Web Development Stack 2. See the warning which recommends not installing to C:\Program Files (x86) which can be restricted by UAC (User Account Control). In the steps below XAMPP is installed to a USB flash drive for portability.

    Introducción a la Ingeniería del Software y a los Sistemas de Información Laboratory: XAMP and APTANA February 2013 Goal of the practice 1.- Introduction to In this course, we are going to use: - Apache web server - PHP installed as a module for Apache It is possible to download all those applications and to install them independently. However, this process takes time and it is prone to errors. That is why we use XAMPP. XAMPP is an easy to install Apache distribution containing MySQL, PHP and Perl together with other components such as ftp servers, mail servers, OpenSSL,… As a matter of fact, the name of XAMPP stands for X (for all the operating systems) Apache, MySQL, PHP, Perl. XAMPP is really very easy to install and to use - just download, extract and start. XAMPP is free of charge and most of its components are open source. XAMPP can be downloaded from: http://www.apachefriends.org/en/xampp.html. In that web you can also find installation instructions for Windows, MacOS and Linux. You must have privileged access to install and configure XAMPP, otherwise there will be errors during the installation. After the installation, all XAMPP services are managed in the XAMPP Control Panel Application, which can be started by executing xampp-control.exe: Figure 1: XAMPP Control Panel From this control panel, the main modules (such as Apache) can be started and stopped. Additionally, it also allows configuring these modules as services (enabling “SVC” in the left), which are automatically started when the system boots.

    The following is a sample chapter from the upcoming Understanding MySQL and MariaDB, coming in 2020 from Andrew Comeau and Comeau Software Solutions. If you enjoy this preview, please check back at ComeauSoftware.com for more details and updates on anticipated release dates. https://www.comeausoftware.com/understanding-mysql-and-mariadb/ All material, Copyright 2019 – Andrew Comeau 3 Installing MariaDB with XAMPP Using MariaDB as part of a suite of web development tools In This Lesson … • Understand the purpose of an Apache - MySQL - PHP (AMP) software stack • Recognize the variations in AMP stack packages available for download • Install an AMP stack for use in developing databases and hosting web applications What is an AMP Stack? As powerful as MySQL is, it's rarely used on its own. Most developers will want additional tools such as programming languages and interface tools to escape the tedium of working on the command line all the time. This is one of the reasons that MySQL is often used in combination with other tools that will enable the design of user-friendly sites. This means either creating or downloading a ready-made AMP stack. AMP usually stands for "Apache-MySQL-PHP" although the P might also stand for Perl or Python. In general, it simply refers to one or more programming languages that are included with the software stack. An AMP stack is called a stack because each tool within it addresses a different aspect of database and web development and helps support the others. • Apache is a web server - software that can respond to requests for pages and other content within a website.
