Highly-Available WordPress Setup inside AWS VPC using Terraform & Ansible

In this post,we’ll create the Infrastructure for Highly-Available WordPress website over AWS using Terraform and then install the WordPress using Ansible. If you don’t know about the Terraform, please check this link.

We’ll use the Terraform to create the fully operational AWS VPC infrastructure(subnets,routeing tables,igw etc), it will also create everything that need to be for creating EC2 and RDS instances (security key, security group, subnet group). It will also create the Elastic Load Balancer and add the EC2 instance(s) automatically to it as well as creating the Route53 entry for this wordpress site and add the ELB alias to it.

Ansible will be used to deploy the wordpress on the EC2 instances that have been created via Terraform, that will be fault tolerant and highly available.

Requirements:

  • Terraform
  • Ansible
  • AWS admin access

If you have completed the previous parts of this series, then you have already clone the git repo that contains all the roles, if not then clone the git repo:

git clone https://github.com/arbabnazar/ansible-aws-roles.git
cd ansible-aws-roles

Modified the aws.yml playbook to add the desired roles:

Note: May be, you have already noticed that we have also added the vpc, ec2sg, ec2key, ec2instance and elb roles in the playbook, it will not re-create all this except the EC2 instance(this role is not idempotent), if you have created them in the previous parts, because Ansible is idempotent.

In this post,we’ll learn that how we can do Highly-Available WordPress Installation inside AWS VPC using Ansible, for this purpose we’ll be using Ubuntu 14.04 LTS EC2 Instances but you can modify it easily for RPM-based systems. If you don’t know about the Ansible, please check this link.

The purpose of Ansible AWS VPC Highly-Available WordPress(AAVHAW) is to create a fully operational AWS VPC infrastructure(subnets,routeing tables,igw etc), it will also create everything that need to be for creating EC2 and RDS instances (security key, security group, subnet group).

It will also create the Elastic Load Balancer and add the EC2 instance(s) automatically that were created using this playbook as well as creating the Route53 entry for this wordpress site and add the ELB alias to it.

Beside that, this playbook will also run the essential role(updating and patching the OS, configuring NTP,creating users etc) and deploy the wordpress on them, that will be fault tolerant and highly available.

NOTE: The part of the play, ‘webserver.yml‘, is not idempotent. Every time it run, will create a new EC2 instances.
