Step 2: Launch a Cluster

Before you continue, be sure you have completed Determine Your Requirements [Every time].

The cluster you're about to launch will be live, and not running in a sandbox. You will incur the standard ElastiCache usage fees for the instance until you delete it. The total charges will be minimal (typically less than a dollar) if you complete the exercise described here in one sitting and delete your cluster when you are finished. For more information about ElastiCache usage rates, see https://aws.amazon.com/elasticache/.

Important

Your cluster will be launched in an Amazon VPC. Before you start creating your cluster, you need to create a subnet group. For more information, see Creating a Subnet Group.

To create a standalone Redis (cluster mode disabled) cluster

  1. Sign in to the AWS Management Console and open the Amazon ElastiCache console at https://console.aws.amazon.com/elasticache/.

  2. Choose Get Started Now.

    If you already have an available cluster, choose Launch Cluster.

  3. From the dropdown in the upper right corner, choose the region you want to launch this cluster in.

  4. For Cluster engine, choose Redis.

  5. Make sure Cluster Mode enabled (Scale Out) is not chosen.

  6. Complete the Redis settings section as follows:

    1. In Name, type a name for your cluster.

      Cluster naming constraints

      • Must contain from 1 to 20 alphanumeric characters or hyphens.

      • Must begin with a letter.

      • Cannot contain two consecutive hyphens.

      • Cannot end with a hyphen.

    2. From the Engine version compatibility list, choose the Redis engine version you want to run on this cluster. Unless you have a specific reason to run an older version, we recommend that you choose the latest version.

    3. In Port, accept the default port, 6379. If you have a reason to use a different port, enter the port number.

    4. From Parameter group, choose the parameter group you want to use with this cluster, or choose "Create new" to create a new parameter group to use with this cluster. For this exercise, accept the default parameter group.

      For more information, see Creating a Parameter Group.

    5. For Node type, choose the node type that you want to use for this cluster. For this exercise, above the table choose the t2 instance family, choose cache.t2.small, and finally choose Save.

      For more information, see Choosing Your Node Size.

    6. From Number of replicas, choose the number of read replicas you want for this cluster. Since in this exercise we're creating a standalone cluster, choose None.

      When you choose None, the Replication group description field disappears.

  7. Choose Advanced Redis settings and complete the section as follows:

    Note

    The Advanced Redis settings details are slightly different if you are creating a Redis (cluster mode enabled) replication group. For a step-by-step walk through to create a Redis (cluster mode enabled) replication group, see Creating a Redis (cluster mode enabled) Cluster with Replicas from Scratch.

    1. From the Subnet group list, choose the subnet you want to apply to this cluster. For this exercise, choose default.

      For more information, see Subnets and Subnet Groups.

    2. Choose how you want the Availability zone(s) chosen for this cluster. You have two options.

      • No preference – ElastiCache will choose the availability zone.

      • Specify availability zones – You specify the availability zone for your cluster.

      For this exercise, choose Specify availability zones and then choose an availability zone from the list below Primary.

      For more information, see Choosing Regions and Availability Zones.

    3. From the Security groups list, choose the security groups that you want to use for this cluster. For this exercise, choose default.

      For more information, see ElastiCache and Security Groups.

    4. If you are going to seed your cluster with data from a .RDB file, in the Seed RDB file S3 location box, enter the Amazon S3 location of the .RDB file.

      For more information, see Seeding a New Cluster with an Externally Created Backup (Redis).

    5. Because this is not a production cluster, clear the Enable automatic backups check box.

      For more information on Redis backup and restore, see ElastiCache Backup and Restore (Redis).

    6. The Maintenance window is the time, generally an hour, each week where ElastiCache schedules system maintenance on your cluster. You can allow ElastiCache to specify the day and time for your maintenance window (No preference), or you can specify the day and time yourself (Specify maintenance window. If you choose Specify maintenance window, specify the Start day, Start time, and Duration (in hours) for your maintenance window. For this exercise, choose No preference.

      For more information, see Maintenance Window.

    7. For Notifications, leave it as Disabled.

  8. Choose Create cluster to launch your cluster, or Cancel to cancel the operation.
