#はじめに
先日RHEL8にs3をマウントして使いたいという要望があったので、
パッケージの導入～設定～動作確認をやってみました。

2.追加ソフトウェア
3.s3バケットの用意
4.パッケージ導入

6.s3マウントと確認
7.RHEL8を再起動し、再起動後のマウント状態を確認
8.参考
#1.前提条件
- ここでまとめた情報は、AWS上のRHEL8.4 20210825のamiをベースにしています。
- SELINUXは無効化してあります。
- AmazonS3FullAccessポリシーをアタッチしたロールを作成し、作成したロールをサーバロールとしてアタッチしています。
- 使用リージョンはap-northeast-1です。
- s3をマウントする際のユーザは、ec2-userとします。
#2.追加パッケージ・ソフトウェア
##2-1 OS標準の追加パッケージは、以下の通りです。
- curl
- langpack-ja
- jq
- unzip
##2-2 追加ソフトウェアとして、以下の通りです。
- AWS CLI Version2を導入して、aws configureを実施済みです。
- Amazon ssm agentを導入して、自動起動を設定済みです。
#3.s3バケットの用意
##3-1 テスト用にtest-s3fs-20210914バケットを作成します。
$ aws s3 mb s3://test-s3fs-20210914
make_bucket: test-s3fs-20210914
$ aws s3 ls s3://test-s3fs-20210914
##3-2 バケットにテスト用ファイルを配置します。
$ date > s3fs-test.txt
$ cat s3fs-test.txt
Tue Sep 14 10:59:24 UTC 2021
$ aws s3 cp s3fs-test.txt s3://test-s3fs-20210914
upload: ./s3fs-test.txt to s3://test-s3fs-20210914/s3fs-test.txt
$ aws s3 ls s3://test-s3fs-20210914
2021-09-14 10:59:26 29 s3fs-test.txt
#4.パッケージ導入
##4-1 s3fs-fuseをパッケージを導入するため、EPELパッケージを導入し、EPELリポジトリを有効化します。

#5./etc/fstab設定
ec2-userの権限で、/mediaにtest-s3fs-20210914をマウント設定するを記載します。
/etc/fstab
test-s3fs-20210914 /media fuse.s3fs _netdev,rw,allow_other,uid=1000,gid=1000,iam_role=auto,endpoint=ap-northeast-1 0 0
以下の編集コマンドを実行して、/etc/fstabを編集し、その結果を確認します。
$ sudo vi /etc/fstab
