Using azure siterecovery with mysql

Question

Pulumi · Accepted Answer

To use Azure Site Recovery with MySQL, you need to have a MySQL server running that you want to protect with disaster recovery. Azure Site Recovery (ASR) can replicate your MySQL server VM to another Azure region for high availability.

First, you need to have two resources:
1. A MySQL server, which can be set up on a virtual machine.
2. Azure Site Recovery services that will handle the replication.

Here's a step-by-step guide to set up Azure Site Recovery for a MySQL server with Pulumi using TypeScript:

1. **Set up a Virtual Machine** to host your MySQL server. You would typically install MySQL on a Linux VM.

2. **Set up the Azure Recovery Services Vault**, which is where your replicated data will be stored in a secondary region.

3. **Configure the Source and Target for replication** by using the `RecoveryServicesReplicationProtectedItem` resource.

Please note that setting up MySQL is out of the scope of Pulumi, as it involves configuring the software inside the virtual machine. Pulumi is used only to provision and manage the infrastructure components.

Below is a basic program that shows how you would set up the virtual machine and Azure Site Recovery Services with Pulumi. This does not include the actual MySQL configuration, which needs to be done on the VM after it is provisioned.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure from "@pulumi/azure-native";

const resourceGroupName = new azure.resources.ResourceGroup("myResourceGroup");

// Create a network for the VM
const virtualNetwork = new azure.network.VirtualNetwork("myVirtualNetwork", {
    resourceGroupName: resourceGroupName.name,
    addressSpace: {
        addressPrefixes: ["10.0.0.0/16"],
    },
});

const subnet = new azure.network.Subnet("mySubnet", {
    resourceGroupName: resourceGroupName.name,
    virtualNetworkName: virtualNetwork.name,
    addressPrefix: "10.0.1.0/24",
});

const publicIp = new azure.network.PublicIPAddress("myPublicIp", {
    resourceGroupName: resourceGroupName.name,
    publicIPAllocationMethod: azure.network.IPAllocationMethod.Dynamic,
});

const networkInterface = new azure.network.NetworkInterface("myNetworkInterface", {
    resourceGroupName: resourceGroupName.name,
    ipConfigurations: [{
        name: "myIpConfiguration",
        subnet: {
            id: subnet.id,
        },
        publicIPAddress: {
            id: publicIp.id,
        },
    }],
});

// Create a virtual machine which will act as your MySQL server
const virtualMachine = new azure.compute.VirtualMachine("myVM", {
    resourceGroupName: resourceGroupName.name,
    networkProfile: {
        networkInterfaces: [{
            id: networkInterface.id,
        }],
    },
    hardwareProfile: {
        vmSize: azure.compute.VirtualMachineSizeTypes.Standard_DS1_v2,
    },
    osProfile: {
        computerName: "myvm",
        adminUsername: "adminuser",
        adminPassword: "password",
        // You'd typically use a custom script extension to install MySQL
    },
    storageProfile: {
        imageReference: {
            // Ubuntu Server 18.04 LTS - Gen1
            publisher: "Canonical",
            offer: "UbuntuServer",
            sku: "18.04-LTS",
            version: "latest",
        },
        osDisk: {
            createOption: "FromImage",
            name: "myosdisk1",
        },
    },
});

// Setting up the Recovery Services Vault
const recoveryVault = new azure.recoveryservices.Vault("myRecoveryVault", {
    resourceGroupName: resourceGroupName.name,
    location: resourceGroupName.location,
    sku: {
        name: "Standard",
    },
});

// Assuming you've already set up a secondary region and want to replicate there
const replicationPolicy = new azure.siterecovery.ReplicationPolicy("myReplicationPolicy", {
    resourceGroupName: resourceGroupName.name,
    recoveryVaultName: recoveryVault.name,
    // Configure the replication policy settings according to your needs
});

// Protecting your MySQL VM with Site Recovery
const replicationProtectedItem = new azure.siterecovery.ReplicationProtectedItem("myReplicationProtectedItem", {
    resourceGroupName: resourceGroupName.name,
    recoveryVaultName: recoveryVault.name,
    // Policy ID from the one we created above
    policyId: replicationPolicy.id,
    // ...other necessary configuration for VM protection
});

export const vmId = virtualMachine.id;
export const recoveryVaultId = recoveryVault.id;
export const replicationPolicyId = replicationPolicy.id;
```

This code sets up a virtual machine in Azure along with the necessary networking resources. Then it sets up the Recovery Services Vault that you can use with the Azure Site Recovery to replicate your virtual machine to a secondary region.

Please remember to replace any placeholder values with your actual configurations, for example `adminUsername`, and `adminPassword`. When setting up MySQL, ensure that it is configured to work with Azure Site Recovery, which might mean setting up MySQL replication to handle database state consistently during failover events.

Make sure you read through Azure's documentation on how to configure the MySQL server, synchronization, and the OS for high availability:

- [Azure Site Recovery Documentation](https://docs.microsoft.com/en-us/azure/site-recovery/)
