Changes to the ARM template that may have occurred since the creation of this example may not be reflected here. 4 5 This template deploys a WordPress site in Azure backed by MySQL replication with one master and one slave server. It has the following capabilities: 6 7 - Installs and configures GTID based MySQL replication on CentOS 6 8 - Deploys a load balancer in front of the 2 MySQL VMs 9 - MySQL, SSH, and MySQL probe ports are exposed through the load balancer using Network Security Group rules. 10 - WordPress accesses MySQL through the load balancer. 11 - Configures an http based health probe for each MySQL instance that can be used to monitor MySQL health. 12 - WordPress deployment starts immediately after MySQL deployment finishes. 13 - Details about MySQL management, including failover, can be found [here](https://github.com/Azure/azure-quickstart-templates/tree/master/mysql-replication). 14 15 If you would like to leverage an existing VNET, then please see the [documentation here](https://www.terraform.io/docs/import/index.html) to learn about importing existing resources into Terraform and bringing them under state management by this template. To import your existing VNET, you may use this command. 16 17 ``` 18 terraform import azurerm_virtual_network.testNetwork /subscriptions/<YOUR-SUB-ID-HERE>/resourceGroups/<existing-resource-group-name>/providers/Microsoft.Network/virtualNetworks/<existing-vnet-name> 19 ``` 20 21 ## main.tf 22 The `main.tf` file contains the resources necessary for the MySql replication deployment that will be created. It also contains the Azure Resource Group definition and any defined variables. 23 24 ## website.tf 25 The `website.tf` contains an `azurerm_template_deployment` that will deploy the Wordpress website. 26 27 ## outputs.tf 28 This data is outputted when `terraform apply` is called, and can be queried using the `terraform output` command. 29 30 ## provider.tf 31 You may leave the provider block in the `main.tf`, as it is in this template, or you can create a file called `provider.tf` and add it to your `.gitignore` file. 32 33 Azure requires that an application is added to Azure Active Directory to generate the `client_id`, `client_secret`, and `tenant_id` needed by Terraform (`subscription_id` can be recovered from your Azure account details). Please go [here](https://www.terraform.io/docs/providers/azurerm/) for full instructions on how to create this to populate your `provider.tf` file. 34 35 ## terraform.tfvars 36 If a `terraform.tfvars` file is present in the current directory, Terraform automatically loads it to populate variables. We don't recommend saving usernames and password to version control, but you can create a local secret variables file and use `-var-file` to load it. 37 38 If you are committing this template to source control, please insure that you add this file to your `.gitignore` file. 39 40 ## variables.tf 41 The `variables.tf` file contains all of the input parameters that the user can specify when deploying this Terraform template.
