これはなに

ElastiCache redisの理解を深めるために検証してみる
ElastiCache redisとEC2を接続させるまで試してみる

前提

同じVPC内に作成
EC2 x 1
redis x 1

手順

SG作成

EC2のSG：redis用にアウトバウンドを追加しておく

redis用のSG：作成段階で変更できなかったので作成後に関連付けられた「default」のSGのインバウンドを追加する

subnet,subnetgroup作成

redis用に作成

EC2作成

EC2名：nagano-test-redis
SG：nagano-test-sg-redis-ec2(先ほど作成したSG)
subnet：public-subnet-a
role：ssmを使用するために付与
EIP：付与

redis作成

subnet：private-subnet-a,private-subnet-c
上記以外は以下パラメータで作成

EC2へ接続

ssmで接続
パッケージインストール
