Getting Started with Amazon ElastiCache for Redis<\/span><\/h1>\n

 <\/p>\n

This tutorial will guide you that how to create, granting access to, connect to, and finally delete a Redis (cluster mode disabled) cluster using the ElastiCache Management Console<\/p>\n

Amazon ElastiCache<\/a> supports high availability through the use of Redis replication groups.<\/p>\n

Starting with Redis version 5.0.5, ElastiCache Redis supports partitioning your data across multiple node groups, with each node group implementing a replication group. This tutorial creates a standalone Redis cluster.<\/p>\n

 <\/p>\n

Steps to Create Amazon ElastiCache for Redis Cluster<\/h3>\n

Determine Requirements<\/p>\n

Setting Up<\/p>\n

Step 1: Launch a Cluster<\/p>\n

#Step 2: Authorize Access<\/p>\n

Step 3: Connect to a Cluster’s Node<\/p>\n

#Step 4: Delete Your Cluster (To avoid Unnecessary Charges)<\/p>\n

 <\/p>\n

Determine Requirements<\/h3>\n

Before you create a Redis cluster or replication group, you should always determine the requirements for a cluster or replication group so that when you create it, it will meet your business needs and not need to be redone. Because in this exercise we will largely accept default values for the cluster, we will dispense with determining requirements.<\/p>\n

 <\/p>\n

Setting Up<\/h3>\n

Following, you can find topics that describe the one-time actions you must take to start using an ElastiCache.<\/p>\n

 <\/p>\n

Topics<\/h3>\n

Create Your AWS Account<\/a><\/p>\n

Set Up Your Permissions (New an ElastiCache Users Only)<\/p>\n

 <\/p>\n

Create Your AWS Account<\/h3>\n

To use an Amazon ElastiCache<\/a>, you must have an active AWS account<\/a> and permissions to access ElastiCache and other AWS resources.<\/p>\n

If you don’t already have an AWS account, create one now. AWS accounts are free. You will not charge for signing up for an AWS service, only for using AWS services<\/a>.<\/p>\n

 <\/p>\n

Set Up Your Permissions (New ElastiCache Users Only)<\/h3>\n

Amazon ElastiCache creates & uses service-linked roles to provision resources and access other AWS resources<\/a> and services on your behalf. For ElastiCache to create a service-linked role for the user, use the AWS-managed policy<\/a> named\u00a0AmazonElastiCacheFullAccess. This role comes pre-provisioned with permission that the service to create a service-linked role on your behalf.<\/p>\n

You might decide not to use the default policy and instead to use a custom-managed policy. In this case, make sure that you have either permissions to call\u00a0iam:createServiceLinkedRole\u00a0or that you have created an ElastiCache service-linked role.<\/p>\n

 <\/p>\n

Using the following<\/h3>\n

Using Service-Linked Roles for Amazon ElastiCache<\/p>\n

 <\/p>\n

Step 1: Launch a Cluster<\/h3>\n

The cluster you’re about to launch will be live, and not running in the sandbox. You will incur the standard ElastiCache usage fees for the instance until you delete the cluster. The total charges will be minimum (typically less than a dollar) if you complete the exercise described herein one sitting and delete your cluster when you are finished.<\/p>\n

 <\/p>\n

Important<\/h3>\n

Your cluster is launched in an Amazon VPC. Before you start creating your cluster, you need to create a subnet group for the cluster.<\/p>\n

To create a standalone Redis (cluster mode disabled\/single node) cluster<\/strong><\/p>\n

    \n
  1. Sign in to the AWS Management Console and open the Amazon ElastiCache console at\u00a0https:\/\/console.aws.amazon.com\/elasticache\/.<\/li>\n
  2. Choose to\u00a0Get Started Now<\/strong>.<\/li>\n<\/ol>\n

    If you already have an available cluster, select\u00a0Launch Cluster<\/strong>.<\/p>\n

      \n
    1. From the list in the upper right corner, choose the AWS Region<\/a> that you want to launch this cluster in.<\/li>\n
    2. For\u00a0Cluster engine<\/strong>, choose\u00a0Redis<\/strong>.\"\"<\/li>\n
    3. Make sure that\u00a0Cluster-Mode enabled (Scale-Out)<\/strong>is not selected.<\/li>\n
    4. Complete the\u00a0Redis cluster settings section<\/strong>\u00a0as follows:\n
