This file is a log of everything I've encountered when trying to migrate a Node.js, Elastic Beanstalk application from the Amazon Linux platform to the Amazon Liunx 2 platform. Here's why you should migrate:

1. LTS support up to 2023 source
2. The Amazon Linux AMI's end-of-life is December, 2020 source
3. Amazon Linux 2 has some big package upgrades (GCC, Glibc, etc.)
4. Elastic Beanstalk also has some upgrades on top of Amazon Linux 2 (e.g. faster deploys)

Setup redis-cli on AWS EC2

SSH into your EC2 instance. Run the following:

$ sudo yum install gcc This may return an "already installed" message. That's OK.

$ wget http://download.redis.io/redis-stable.tar.gz && tar xvzf redis-stable.tar.gz && cd redis-stable && make

See: http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/GettingStarted.ConnectToCacheNode.Redis.html
