Build Solutions across VPCs with Peering

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.

  1. Challenge

    Create Web_VPC Subnets and Attach a New Internet Gateway

    Using the AWS console, create the Web_VPC VPC with the IPv4 CIDR block. Create the WebIG internet gateway. Modify the route table to attach the internet gateway to the Web_VPC.

  2. Challenge

    Create a Peering Connection

    Create a peering connection called DBtoWeb. Peer the newly created Web_VPC with the DB_VPC. Ensure DB_VPC is the requester and Web_VPC is the accepter. Accept the request.

  3. Challenge

    Create an EC2 Instance and configure Wordpress

    Launch a new public facing Ubuntu Server 20.04 LTS EC2 instance in the Web_VPC VPC using the provided bootstrap user data script.

    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
    tar zxvf wordpress.tar.gz
    cd wordpress
    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" .. "z", "A" .. "Z", 0 .. 9);
        push @chars, split //, "!@#$%^&*()-_ []{}<>~\`+=,.;:/?|";
        sub salt { join "", map $chars[ rand @chars ], 1 .. 64 }
      s/put your unique phrase here/salt()/ge
    ' wp-config.php
    mkdir wp-content/uploads
    chmod 775 wp-content/uploads
    mv 000-default.conf /etc/apache2/sites-enabled/
    mv /wordpress /var/www/
    apache2ctl restart

    Configure Wordpress by editing /var/www/wordpress/wp-config.php to point DB_HOST to the RDS database endpoint.

  4. Challenge

    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

  5. Challenge

    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.
