In the Google Cloud console, on the project selector page,
select or create a Google Cloud project.
Avere un file Terraform a cui puoi aggiungere la risorsa Memorystore. Per
istruzioni sulla configurazione di Terraform con Google Cloud, consulta la Guida introduttiva al provider Google Cloud.
Creazione di un'istanza Memorystore for Redis
L'esempio di risorsa Terraform seguente crea un'istanza Redis di livello base da 2 GiB nella regione us-central1 nel livello BASIC. Per ulteriori informazioni
sui livelli, consulta Funzionalità dei livelli Redis.
Aggiungi la seguente risorsa al file di configurazione Terraform:
resource "google_redis_instance" "my_memorystore_redis_instance" {
name = "myinstance"
tier = "BASIC"
memory_size_gb = 2
region = "us-central1"
redis_version = "REDIS_6_X"
}
(Facoltativo) Aggiungi il seguente valore di output
al file di configurazione Terraform per stampare l'indirizzo IP dell'istanza Redis, necessario più avanti in questa guida rapida:
output "host" {
description = "The IP address of the instance."
value = "${google_redis_instance.my_memorystore_redis_instance.host}"
}
Esegui terraform init.
Esegui terraform plan e rivedi la risorsa da creare.
Esegui terraform apply per creare.
Connettersi all'istanza Redis da una VM di Compute Engine
Poi, connettiti all'istanza Redis appena creata.
Puoi connetterti all'istanza Redis da qualsiasi VM di Compute Engine
che utilizza la rete autorizzata dell'istanza Redis con un indirizzo IP RFC 1918 supportato.
Se non hai già una VM di Compute Engine che utilizza la stessa rete autorizzata dell'istanza Redis, creane una e connettiti seguendo la Guida rapida all'utilizzo di una VM Linux.
Installa telnet utilizzando apt-get:
sudoapt-getinstalltelnet
Nel terminale, inserisci il comando telnet seguito dall'indirizzo IP dell'istanza Redis, sostituendo
variables con i valori appropriati.
telnet instance-ip-address 6379
In caso di esito positivo, il comando restituirà questo risultato:
Trying instance-ip-address…
Connected to instance-ip-address
Nella sessione di Telnet, inserisci alcuni comandi Redis:
Digita:
PING
Risultato:
PONG
Invio
SET HELLO WORLD
Risultato:
+OK
Digita:
GET HELLO
Risultato:
$5
WORLD
Esegui la pulizia
Per evitare che al tuo account Google Cloud vengano addebitati costi relativi alle risorse utilizzate in questa guida rapida, elimina l'istanza Redis seguendo questi passaggi:
Rimuovi la risorsa google_redis_instance dal file di configurazione Terraform.
Esegui Terraform init, plan e apply per eliminare la risorsa Redis.
Elimina tutte le VM di Compute Engine che hai creato per questa guida rapida.

It also shows you how to connect to the instance using telnet.\n\nThis quickstart uses the [Google Cloud Platform Provider](https://registry.terraform.io/providers/hashicorp/google/latest/docs)\nfor Terraform.\n\nBefore you begin\n----------------\n\n- Sign in to your Google Cloud account. If you're new to Google Cloud, [create an account](https://console.cloud.google.com/freetrial) to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.\n- In the Google Cloud console, on the project selector page,\n select or create a Google Cloud project.\n\n | **Note**: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.\n\n [Go to project selector](https://console.cloud.google.com/projectselector2/home/dashboard)\n-\n [Verify that billing is enabled for your Google Cloud project](/billing/docs/how-to/verify-billing-enabled#confirm_billing_is_enabled_on_a_project).\n\n- In the Google Cloud console, on the project selector page,\n select or create a Google Cloud project.\n\n | **Note**: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project.

If you haven't already, [install the Google Cloud SDK](/sdk/docs).\n\n When prompted, choose the project that you selected or created above.\n2. If you already have the Google Cloud SDK installed, update it.\n\n ```\n gcloud components update\n ```\n3. Enable the Memorystore for Redis API \n [Memorystore for Redis](https://console.cloud.google.com/apis/library/redis.googleapis.com)\n4. Have a Terraform file to which you can add the Memorystore resource. For instructions on setting up Terraform with Google Cloud, see [Getting Started with the Google Cloud Provider](https://registry.terraform.io/providers/hashicorp/google/latest/docs/guides/getting_started).\n\n\u003cbr /\u003e\n\nCreating a Memorystore for Redis instance\n-----------------------------------------\n\nThe following Terraform resource example creates a 2 GiB Basic Tier Redis\ninstance in the `us-central1` region in the BASIC tier. For more information\nabout tiers, see [Redis tier capabilities](/memorystore/docs/redis/redis-tiers).\n\n1. Add the following resource to your Terraform configuration file:\n\n ```\n resource \"google_redis_instance\" \"my_memorystore_redis_instance\" {\n name = \"myinstance\"\n tier = \"BASIC\"\n memory_size_gb = 2\n region = \"us-central1\"\n redis_version = \"REDIS_6_X\"\n }\n ```\n2. **(Optional)** Add the following [output value](https://www.terraform.io/docs/configuration/outputs.html)\n to your Terraform configuration file to print the IP address of the Redis\n instance, which is needed later in this quickstart:\n\n ```\n output \"host\" {\n description = \"The IP address of the instance.\"\n value = \"${google_redis_instance.my_memorystore_redis_instance.host}\"\n }\n ```\n3. Run `terraform init`.\n\n4. Run `terraform plan`, and review the resource to be created.\n\n5. Run `terraform apply` to create.\n\nConnecting to the Redis instance from a Compute Engine VM\n---------------------------------------------------------\n\nNext, connect to the newly created Redis instance.\n\nYou can connect to the Redis instance from any Compute Engine VM\nthat uses the Redis instance's authorized network with a [supported RFC 1918 IP address](/memorystore/docs/redis/networking#supported_and_unsupported_networks).\n\n1. If you don't already have a Compute Engine VM that uses that same\n authorized network as your Redis instance, create one and connect to it by\n following [Quickstart using a Linux VM](/compute/docs/create-linux-vm-instance).\n\n2. Install `telnet` using `apt-get`:\n\n sudo apt-get install telnet\n\n3. From the terminal, telnet to the IP address of the Redis instance, replacing\n \u003cvar translate=\"no\"\u003evariables\u003c/var\u003e with appropriate values.\n\n ```\n telnet instance-ip-address 6379\n ```\n\n If successful, the command will return this result: \n\n ```\n Trying instance-ip-address…\n Connected to instance-ip-address\n ```\n4. In the telnet session, enter some Redis commands:\n\n Enter: \n\n ```\n PING\n ```\n\n Result: \n\n ```\n PONG\n ```\n\n Enter \n\n ```\n SET HELLO WORLD\n ```\n\n Result: \n\n ```\n +OK\n ```\n\n Enter: \n\n ```\n GET HELLO\n ```\n\n Result: \n\n ```\n $5\n WORLD\n ```\n\nClean up\n--------\n\nTo avoid incurring charges to your Google Cloud account for the resources used\nin this quickstart, delete the Redis instance using the steps below:\n\n1. Remove the `google_redis_instance` resource from your Terraform configuration file.\n2. Run Terraform `init`, `plan`, and `apply` to destroy the Redis resource.\n3. [Delete](/compute/docs/create-linux-vm-instance#clean-up) any Compute Engine VMs you created for this quickstart.\n\nWhat's next\n-----------\n\n- Learn more about [creating and managing instances](/memorystore/docs/redis/create-manage-instances).\n- Learn about other ways to [connect to your Redis instance](/memorystore/docs/redis/connecting-redis-instance).\n- Learn about the characteristics of a [Redis instance](/memorystore/docs/redis/instances)."]]
