Capítulo 2. Configuração de um cluster Red Hat High Availability no Microsoft Azure

Procedimento

1. Autentique seu sistema com Azure e faça o login.

   $ az login

   Nota

   Se um navegador estiver disponível em seu ambiente, o CLI abre seu navegador para a página de login no Azure.

   Exemplo:

   [clouduser@localhost]$ az login
   To sign in, use a web browser to open the page https://aka.ms/devicelogin and enter the code FDMSCMETZ to authenticate.
     [
       {
         "cloudName": "AzureCloud",
         "id": "Subscription ID",
         "isDefault": true,
         "name": "MySubscriptionName",
         "state": "Enabled",
         "tenantId": "Tenant ID",
         "user": {
           "name": "clouduser@company.com",
           "type": "user"
         }
       }
     ]

2. Criar um grupo de recursos em uma região Azure.

   Grupo az criar --nome resource-group --local azure-region

   Exemplo:

   [clouduser@localhost]$ az group create --name azrhelclirsgrp --location southcentralus
   {
     "id": "/subscriptions//resourceGroups/azrhelclirsgrp",
     "location": "southcentralus",
     "managedBy": null,
     "name": "azrhelclirsgrp",
     "properties": {
       "provisioningState": "Succeeded"
     },
     "tags": null
   }

3. Criar uma conta de armazenamento.

   $ az criar conta de armazenamento -l azure-region -n storage-account-name -g resource-group --sku sku_type --kind StorageV2

   Copy to Clipboard Toggle word wrap

   Exemplo:

   [clouduser@localhost]$ az storage account create -l southcentralus -n azrhelclistact -g azrhelclirsgrp --sku Standard_LRS --kind StorageV2
   {
     "accessTier": null,
     "creationTime": "2017-04-05T19:10:29.855470+00:00",
     "customDomain": null,
     "encryption": null,
     "id": "/subscriptions//resourceGroups/azrhelclirsgrp/providers/Microsoft.Storage/storageAccounts/azrhelclistact",
     "kind": "StorageV2",
     "lastGeoFailoverTime": null,
     "location": "southcentralus",
     "name": "azrhelclistact",
     "primaryEndpoints": {
       "blob": "https://azrhelclistact.blob.core.windows.net/",
       "file": "https://azrhelclistact.file.core.windows.net/",
       "queue": "https://azrhelclistact.queue.core.windows.net/",
       "table": "https://azrhelclistact.table.core.windows.net/"
   },
   "primaryLocation": "southcentralus",
   "provisioningState": "Succeeded",
   "resourceGroup": "azrhelclirsgrp",
   "secondaryEndpoints": null,
   "secondaryLocation": null,
   "sku": {
     "name": "Standard_LRS",
     "tier": "Standard"
   },
   "statusOfPrimary": "available",
   "statusOfSecondary": null,
   "tags": {},
     "type": "Microsoft.Storage/storageAccounts"
   }

4. Obtenha o cordão de conexão da conta de armazenamento.

   Conta de armazenamento az mostrar-conexão de fio -n storage-account-name -g resource-group

   Copy to Clipboard Toggle word wrap

   Exemplo:

   [clouduser@localhost]$ az storage account show-connection-string -n azrhelclistact -g azrhelclirsgrp
   {
     "connectionString": "DefaultEndpointsProtocol=https;EndpointSuffix=core.windows.net;AccountName=azrhelclistact;AccountKey=NreGk...=="
   }

5. Exportar a cadeia de conexão copiando a cadeia de conexão e colando-a no seguinte comando. Esta cadeia de conexão conecta seu sistema à conta de armazenamento.

   $ exportação AZURE_STORAGE_CONNECTION_STRING="storage-connection-string"

   Copy to Clipboard Toggle word wrap

   Exemplo:

   export AZURE_STORAGE_CONNECTION_STRING="DefaultEndpointsProtocol=https;EndpointSuffix=core.windows.net;AccountName=azrhelclistact;AccountKey=NreGk...=="

6. Criar o recipiente de armazenagem.

   Container de armazenamento $ az criar -n container-name

   Copy to Clipboard Toggle word wrap

   Exemplo:

   [clouduser@localhost]$ az storage container create -n azrhelclistcont
   {
     "created": true
   }

7. Criar uma rede virtual. Todos os nós de cluster devem estar na mesma rede virtual.

   $ az rede vnet criar -g resource group --nome vnet-name --subnet-nome subnet-name

   Copy to Clipboard Toggle word wrap

   Exemplo:

   [clouduser@localhost]$ az network vnet create --resource-group azrhelclirsgrp --name azrhelclivnet1 --subnet-name azrhelclisubnet1
   {
     "newVNet": {
       "addressSpace": {
         "addressPrefixes": [
         "10.0.0.0/16"
         ]
     },
     "dhcpOptions": {
       "dnsServers": []
     },
     "etag": "W/\"\"",
     "id": "/subscriptions//resourceGroups/azrhelclirsgrp/providers/Microsoft.Network/virtualNetworks/azrhelclivnet1",
     "location": "southcentralus",
     "name": "azrhelclivnet1",
     "provisioningState": "Succeeded",
     "resourceGroup": "azrhelclirsgrp",
     "resourceGuid": "0f25efee-e2a6-4abe-a4e9-817061ee1e79",
     "subnets": [
       {
         "addressPrefix": "10.0.0.0/24",
         "etag": "W/\"\"",
         "id": "/subscriptions//resourceGroups/azrhelclirsgrp/providers/Microsoft.Network/virtualNetworks/azrhelclivnet1/subnets/azrhelclisubnet1",
         "ipConfigurations": null,
         "name": "azrhelclisubnet1",
         "networkSecurityGroup": null,
         "provisioningState": "Succeeded",
         "resourceGroup": "azrhelclirsgrp",
         "resourceNavigationLinks": null,
         "routeTable": null
       }
     ],
     "tags": {},
     "type": "Microsoft.Network/virtualNetworks",
     "virtualNetworkPeerings": null
     }
   }

8. Criar um conjunto de disponibilidade. Todos os nós de cluster devem estar no mesmo conjunto de disponibilidade.

   $ az vm-disponibilidade -conjunto criar --nome MyAvailabilitySet --recurso-grupo MyResourceGroup

   Copy to Clipboard Toggle word wrap

   Exemplo:

   [clouduser@localhost]$ az vm availability-set create --name rhelha-avset1 --resource-group azrhelclirsgrp
   {
     "additionalProperties": {},
       "id": "/subscriptions/.../resourceGroups/azrhelclirsgrp/providers/Microsoft.Compute/availabilitySets/rhelha-avset1",
       "location": "southcentralus",
       "name": “rhelha-avset1",
       "platformFaultDomainCount": 2,
       "platformUpdateDomainCount": 5,
   
   ...omitted
