CentOS7 ベースの AmazonLinux2 なるものに ansible を入れようとしたら、以下のようなアドバイスをいただきました。
ec2-user@AmazonLinux2:~$ sudo yum install ansible
読み込んだプラグイン:extras_suggestions, langpacks, priorities, update-motd
パッケージ ansible は利用できません。
エラー: 何もしません
ansible is available in Amazon Linux Extra topic "ansible2"
To use, run
# sudo amazon-linux-extras install ansible2

AmazonLinux2 には amazon-linux-extras なるコマンドがあるみたいです。
ansible は ansible2 というパッケージ名ですんなり入ったんですが、このコマンドは、他にも「こんなのありますよ～」というご紹介をしてくれるみたいです。概観するには便利かも。

アプリの実行環境を作るためと割り切れる場合はこっちの方が便利そうですね。ただ、CentOS7 を使った構築を作るためのテスト環境としては、「混ぜるな危険」状態になりそうで、ちょっと微妙な感じです。
