Memorystore para Memcached admite un subconjunto de parámetros de configuración nativos de Memcached que puedes modificar. Debes usar la misma configuración para todos los nodos de
tu clúster. En esta página, se describe cómo realizar las siguientes acciones:
Ver configuraciones de instancias.
Modificar las configuraciones de instancias de la siguiente manera:
Cambios en la configuración de la instancia de etapa de pruebas.
Actualización de los cambios de configuración del nodo.
Memorystore para Memcached requiere que primero actualices las configuraciones y, luego,
apliques los cambios a los nodos de tu clúster. Aplicar una actualización de parámetro a un nodo provoca una limpieza de caché completa en ese nodo.
La ventaja de poder aplicar actualizaciones de parámetros a nodos individuales es que puedes implementar los cambios de forma individual. De esta manera, tu instancia permanecerá en línea y funcional mientras actualizas la configuración.
Haz clic en el ID de la instancia para ver la página Detalles de la instancia.
Visualiza tus opciones de configuración en la sección Configuración.

Para ver los parámetros de configuración con Google Cloud CLI, ingresa el comando describe de la instancia y reemplaza variables por los valores adecuados:

You should use the same configurations for all nodes in\nyour cluster. This page describes how to:\n\n- View instance configurations.\n- Modify instance configurations by:\n - Staging instance configuration changes.\n - Updating node configuration changes.\n\nMemorystore for Memcached requires you to update the configurations first, and then\napply the changes to the nodes in your cluster. Applying a parameter update to\na node causes a full cache flush on that node.\n\nThe advantage to being able to apply parameter updates to individual nodes is\nthat you can roll out changes on a node-by-node basis. Doing so keeps your\ninstance online and functional while you update configurations.\n\nFor a full list of the modifiable and unmodifiable parameters, see [Memcached configuration parameters](/memorystore/docs/memcached/memcached-configs).\n\nViewing configurations\n----------------------\n\n### Console\n\n1. Go to the **Memorystore for Memcached** page in the Google Cloud console. \n [Memorystore for Memcached](https://console.cloud.google.com/memorystore/memcached/instances)\n2. Click the ID of the instance to view the **Instance details** page.\n3. View your settings in the **Configuration** section.\n\n### Gcloud\n\nTo view configuration parameters using the Google Cloud CLI, enter\nthe `describe` command for the instance replacing \u003cvar translate=\"no\"\u003evariables\u003c/var\u003e\nwith appropriate values: \n\n```\ngcloud memcache instances describe instance-id --region=region\n```\n| **Note:** You won't see configuration parameters when running `describe` unless you have changed a configuration from its default value.\n\nFor a list of modifiable configuration parameters and their default values,\nsee [Memcached configuration parameters.](/memorystore/docs/memcached/memcached-configs)\n\nModifying configuration parameters\n----------------------------------\n\n### Console\n\n1. Go to the **Memorystore for Memcached** page in the Google Cloud console. \n [Memorystore for Memcached](https://console.cloud.google.com/memorystore/memcached/instances)\n2. Click the ID of the instance.\n3. Click **Edit Configuration**.\n4. Adjust the value of any parameter that you want to change.\n5. Click the **Continue** button to stage the configuration updates.\n6. Select a node, and click **Update Selected Nodes** one at a time for\n each node, or in batches of nodes.\n\n | **Note:** Updating node configurations one at a time, or in batches, helps you avoid instance unavailability and reduces data loss.\n\n### Gcloud\n\n1. Update the configuration parameters by running the following command:\n\n ```\n gcloud memcache instances update instance-id --region=region --parameters=parameter=value,parameter=value\n ```\n2. List and take note of all node IDs for your instance by running the\n following command:\n\n ```\n gcloud memcache instances describe instance-id --region=region --format=\"value(memcacheNodes.nodeId.list())\"\n ```\n3. Apply the parameters one by one, or in batches, to nodes in your cluster\n by running the following command:\n\n **Note:** Updating node configurations one at a time, or in batches, helps you avoid instance unavailability and reduces data loss. \n\n ```\n gcloud memcache instances apply-parameters instance-id --region=region --node-ids=node-1-id,node-2-id\n ```\n\n Alternatively, you can apply the parameters for all nodes at once by\n using the following command, but we don't recommend it: \n\n ```\n gcloud memcache instances apply-parameters instance-id --region=region --apply-all\n ```\n\nYou cannot simultaneously run the`--parameters` flag with any other flags\nwhen using the Memorystore for Memcached `update` command.\n\nConfiguring parameters using gcloud during instance creation\n------------------------------------------------------------\n\nTo set configuration parameters during creation, enter the following command\nreplacing variables with appropriate values: \n\n```\ngcloud memcache instances create instance-name --size=size --region=region --parameters=parameter=value,parameter=value\n```\n\nYou can simultaneously run the `--parameters` flag with all other flags when\nusing the Memorystore for Memcached `create` command.\n\nClearing configuration parameters to default values using the Google Cloud console\n----------------------------------------------------------------------------------\n\n1. Go to the **Memorystore for Memcached** page in the Google Cloud console. \n [Memorystore for Memcached](https://console.cloud.google.com/memorystore/memcached/instances)\n2. Click the ID of the instance.\n3. Click **Edit Configuration**.\n4. Delete the value of any parameter that you want to reset to default, and leave the field blank.\n5. Click the **Continue** button to stage the configuration updates.\n6. Select a node, and click **Update Selected Nodes** one at a time for each\n node, or in batches of nodes.\n\n | **Note:** Updating node configurations one at a time, or in batches, helps you avoid instance unavailability and reduces data loss.\n\nWhat's next\n-----------\n\n- Review the available [Memcached configurations](/memorystore/docs/memcached/memcached-configs).\n- Learn how to [scale your Memcached instances](/memorystore/docs/memcached/scaling-instances)."]]
