Chapitre 4. Configurer un cluster Red Hat High Availability sur Microsoft Azure

Procédure

1. Authentifiez votre système avec Azure et connectez-vous.

   $ az login

   Note

   Si un navigateur est disponible dans votre environnement, l'interface de programmation ouvre votre navigateur sur la page de connexion Azure.

   Exemple :

   [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. Créer un groupe de ressources dans une région Azure.

   $ az group create --name resource-group --location azure-region

   Exemple :

   [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. Créer un compte de stockage.

   $ az storage account create -l azure-region -n storage-account-name -g resource-group --sku sku_type --kind StorageV2

   Exemple :

   [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. Obtenir la chaîne de connexion du compte de stockage.

   $ az storage account show-connection-string -n storage-account-name -g resource-group

   Exemple :

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

5. Exportez la chaîne de connexion en la copiant et en la collant dans la commande suivante. Cette chaîne connecte votre système au compte de stockage.

   $ export AZURE_STORAGE_CONNECTION_STRING="storage-connection-string"

   Exemple :

   [clouduser@localhost]$ export AZURE_STORAGE_CONNECTION_STRING="DefaultEndpointsProtocol=https;EndpointSuffix=core.windows.net;AccountName=azrhelclistact;AccountKey=NreGk...=="

6. Créer le conteneur de stockage.

   $ az storage container create -n container-name

   Exemple :

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

7. Créez un réseau virtuel. Tous les nœuds du cluster doivent se trouver dans le même réseau virtuel.

   $ az network vnet create -g resource group --name vnet-name --subnet-name subnet-name

   Exemple :

   [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. Créez un ensemble de disponibilité. Tous les nœuds du cluster doivent se trouver dans le même ensemble de disponibilité.

   $ az vm availability-set create --name MyAvailabilitySet --resource-group MyResourceGroup

   Exemple :

   [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,
