A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. In this lab, you will create a new VPC for your WordPress blog to run from. You will then create a VPC peering connection between the new VPC and an existing database VPC. By the end of this lab, you will understand how to create a new VPC from scratch, attach internet gateways, edit routing tables, and peer multiple VPCs together.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Create Web_VPC Subnets and Attach a New Internet Gateway
Using the AWS console, create the
Web_VPCVPC with the192.168.0.0/16IPv4 CIDR block. Create theWebIGinternet gateway. Modify the route table to attach the internet gateway to theWeb_VPC.- Create a Peering Connection
Create a peering connection called
DBtoWeb. Peer the newly createdWeb_VPCwith theDB_VPC. EnsureDB_VPCis the requester andWeb_VPCis the accepter. Accept the request.- Create an EC2 Instance and configure WordPress
Launch a new public facing Ubuntu Server 20.04 LTS EC2 instance in the
Web_VPCVPC using the provided bootstrap user data script.#!/bin/bash sudo apt update -y sudo apt install php-curl php-gd php-mbstring php-xml php-xmlrpc php-soap php-intl php-zip perl mysql-server apache2 libapache2-mod-php php-mysql -y wget https://github.com/ACloudGuru-Resources/course-aws-certified-solutions-architect-associate/raw/main/lab/5/wordpress.tar.gz tar zxvf wordpress.tar.gz cd wordpress wget https://raw.githubusercontent.com/ACloudGuru-Resources/course-aws-certified-solutions-architect-associate/main/lab/5/000-default.conf cp wp-config-sample.php wp-config.php perl -pi -e "s/database_name_here/wordpress/g" wp-config.php perl -pi -e "s/username_here/wordpress/g" wp-config.php perl -pi -e "s/password_here/wordpress/g" wp-config.php perl -i -pe' BEGIN { @chars = ("a" ..

/var/www/wordpress/wp-config.phpto pointDB_HOSTto the RDS database endpoint.- Modify the RDS Security Groups to Allow Connections from the Web_VPC VPC
The RDS instance requires a security group modification to allow access from
192.168.0.0/16.- Test WordPress
Visit the IP address of your EC2 instance in a web browser, and confirm WordPress is working correctly and communicating with the RDS instance via VPC peering.
