How to Connect from Your Local Environment On AWS Redis Elasticache
Make sure you have the Redis client installed on your computer before using the Redis command-line client (redis-cli) from a Mac terminal to connect to an AWS Redis Elasticache instance. Furthermore, ensure that your Elasticache instance’s endpoint and credentials are prepared.
1. Install Redis Client: To install Redis on your Mac terminal, use Homebrew.
brew install redis
2. Find Endpoint and Port: Find your Elasticache instance’s endpoint and port number. This data is available on the Elasticache dashboard of the AWS Management Console.
3. Get the Elasticache instance connected: To establish a connection with the instance, use the redis-cli command.
redis-cli -h mycluster.abc123.us-west-2.elasticache.amazonaws.com -p port_number
4. Authentication: You’ll be asked to input the password if your cluster needs it.
5. Execute Redis Commands: After connecting, you can carry out standard Redis commands.
As an illustration:
set mykey “myvalue”

6. Useful Commands: To check the value of a key, use:
get mykey
7. Alternate Clients: In addition to redis-cli, you may connect to Redis Elasticache using alternative Redis clients like “Ioredis” in Node.js or “Jedis” in Java.
8. Security Considerations: To improve security, think about utilising IAM authentication for Elasticache rather than utilising plaintext passwords. Use the AUTH command and the authentication token if you’re using one.
9. Using OpenSSL: To create a secure connection to the Redis Elasticache instance, you have the option to utilise the OpenSSL command-line tool. It is not advised to use this method as it is less secure than IAM authentication.
10. SSL/TLS Encryption: SSL/TLS encryption is supported by Redis Elasticache. Make sure to utilise SSL/TLS encryption when establishing the connection if you need encryption while it’s in transit.
By following these steps, you can efficiently connect to a Redis Elasticache instance on AWS using the Redis command-line client from your Mac terminal.
