Self answered. Please read below
Steps to Install and Enable Redis
[Self Managed] Install Redis-Server in your webserver, using digitalocean link or for AWS EC2
[AWS ElastiCache] AWS ElastiCache for Redis: How to Use the AWS Redis Service
Install PHP Redis extension. AWS Guide
Apply session.save_path = Endpoint ElastiCache & session.save_handler = redis in php.ini
Restart the services
Confirm the change in php.ini by phpinfo();
Apply Redis session in Yii2 Component as said here
Make sure you follow this.
Use the same security group for EC2 and ElastiCache
Add Redis Port 6379 in AWS Security Group as 0.0.0.0
While configuration In Yii2, main.php add ElastiCache endpoint as host
These steps for the session only, so modify Yii2 main component if you want to use Redis as active data or to cache

I want to use Redis with my nodejs app running in docker on AWS ECS. I'd either want a solution to run Redis in ECS or solution on how to connect ECS with AWS Elasticache
Run Redis in ECS:
Container definitions:
Image:redis:6.0.13
Port mapping:6379
Environment-Command:redis-server,--requirepass redis123456
Login to the Redis Server with password redis123456.It works normally.
Image&Port mapping

Please help me in setting up the connection between azure redis cache and aks. I am building an application where I would like to deploy it in aks and add redis as a service.
You don't connect Azure Redis to AKS, your containers running on AKS will connect to the Azure Cache for Redis instance. When connecting to an Azure Cache for Redis instance, cache clients need the host name, ports, and a key for the cache. Some clients might refer to these items by slightly different names. You can retrieve this information in the Azure portal.

Hi I am trying to connect my Django application to use Redis ElastiCache and am having trouble with getting it connected using AWS. The application is published to an EC2 instance using Elastic Beanstalk and it running perfect when I am not trying to connect to my Redis cache.
From the post here (Setting up ElastiCache Redis with Elastic BeanStalk + Django) I created my ElastiCache to not use a cluster and I have set up both the EC2 instance and the Redis cache to use the same Security Group.
Here is how my cache is configured in settings.py.
CACHES = {
'default': {
'BACKEND': 'django_redis.cache.RedisCache',
'LOCATION': 'redis://my-cache.kjshd.0001.use2.cache.amazonaws.com:6379/',
'OPTIONS': {
'CLIENT_CLASS': 'django_redis.client.DefaultClient'
}
}
}
What am I missing? Are there additional settings that need changed on my cache or somewhere in AWS to open communication? Does this configuration look okay? I was previously using Redis in Azure and this configuration worked but now have the requirement to move to AWS. Is there a way to test that my EC2 instance can connect to Redis? I have the ability to SSH into the server but I was not sure what I would do once I was connected.
Thanks for any help.
After setting the security group, I found out that I needed to change the inbound settings for the security group to connect to my ElastiCache Redis node.
Documentation was found here.

I'm in the process of migrating my Heroku app database from Heroku to AWS RDS Postgres.
On my computer, I can connect to my RDS DB using:
psql -d "postgres://user:password#XXX.rds.amazonaws.com/mydb?sslrootcert=config/amazon-rds-ca-cert.pem&sslmode=require"
However, the same psql command run from within my heroku server just hangs forever.
Also, config/amazon-rds-ca-cert.pem is the RDS certificate that I added to my package as mentioned in the documentation https://devcenter.heroku.com/articles/amazon-rds#authorizing-access-to-rds-instance and here https://stackoverflow.com/a/29467638/943524 (I did combine certificates as I am using a eu-central-1 instance).
Would someone have an idea what is blocking the connection here ?
From the sound of it, your Network ACL or Security Groups are blocking your access. It looks like they allow your computer (perhaps your entire company’s IP) but not Heroku. Check out the NACLs and Security Groups and you should find your answer (i.e. add Heroku IP range to your NACLs and/or Security Groups).
I am new to AWS-SDK and I am running an node.js application on an EC2 instance.
I am trying to use ElastiCache-Redis in the node.js application. However, I can not find the API of ElastiCache to make basic Redis calls. The url below did not provide anything of Redis commands.
http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/ElastiCache.html#addTagsToResource-property
What should I do to issue Redis command to ElastiCache(Redis) in aws-sdk?
The ElastiCache API is used to start, stop & configure Redis and Memcached instances. It is not used for communicating with those instances.
In order to send commands to Redis or Memcached you need to use normal clients, here is the list of Node.js clients for Redis: http://redis.io/clients#nodejs
