In this article I'm going to walk you through process of creating Wordpress plugins. First I'm going to talk about some of the basic concepts in Wordpress plugin development like the actions, hooks, and API's that makes up Wordpress. Then were going to build a plugin where we apply some of the concepts and best practices in developing Wordpress plugins.

###Prerequisites

In order to fully benefit from this tutorial you should have a basic knowledge on PHP. As Wordpress is running on PHP and most of the code that we will be writing will be on PHP. A little bit of knowledge on HTML, CSS and JavaScript is also helpful but not required for this tutorial.

Deploy your site with git on cPanel

The most important: You must have shell access!

This gist assumes:

you have a local git repo
with an online remote repository (github / bitbucket etc)
and a cloud server (Rackspace cloud / Amazon EC2 etc)
your (PHP) scripts are served from /var/www/html/

Linux Server Setup & MERN App Deployment

These are the steps to setup an Ubuntu server from scratch and deploy a MERN app with the PM2 process manager and Nginx. We are using Linode, but you could just as well use a different cloud provider or your own machine or VM.

Create an account at Linode

Click on Create Linode

Choose your server options (OS, region, etc)

SSH Keys

Server initial setup script

Configuration

This script was made for personal purposes, but it can still be useful to many. You NEED to change variables inside the script, like the SSH public key.

Usage

On a new Ubuntu server, run the following command:

	#!/usr/bin/env bash

	if [ "$EUID" -ne 0 ];then
	>&2 echo "This script requires root level access to run"
	exit 1
	fi

	if [ -z "${WORDPRESS_DB_PASSWORD}" ]; then
	>&2 echo "WORDPRESS_DB_PASSWORD must be set"
	>&2 echo "Here is a random one that you can paste:"

	curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg \| sudo apt-key add -
	echo "step1"
	echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" \| sudo tee /etc/apt/sources.list.d/kubernetes.list
	echo "kubeadm install"
	sudo apt update -y
	sudo apt -y install vim git curl wget kubelet=1.23.0-00 kubeadm=1.23.0-00 kubectl=1.23.0-00
	echo "memory swapoff"
	sudo sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
	sudo swapoff -a
	sudo modprobe overlay

	#!/bin/bash
	# System Updates
	sudo apt-get update -y
	sudo apt-get full-upgrade --fix-missing -y
	sudo apt-get autoremove -y
	sudo apt-get -y dist-upgrade
	sudo apt-get -y install linux-headers-$(uname -r)
	#sudo parrot-upgrade
