SuSE Linux Enterprise Server: basic usage memo
いきさつ: なぜに SLES?
- Oracle Database Express Edition(XE) を AWS 上で利用したいと思ったときに RHEL よりも Subscription 費用が安かったので…
目的
- 基本的な管理方法を備忘録的に残しておく
- SLES に固有っぽいもの中心に
- 基本的な情報収集
- パッケージ管理コマンド
- サービスの開始・終了 etc
- SLES に固有っぽいもの中心に
- 気がついたら書き足していく
対象
- バージョン: SLES 11 SP4
- Oracle XE 11 のサポート環境を想定しているので
実験環境
※ 注意: 以下の環境は無料ではありません!
-
AWS
- Region: N.Virginia
- AMI: suse-sles-11-sp4-v20160804-hvm-ssd-x86_64 (ami-0434a713)
- Instance Type: t2.micro
- あくまで参考価格:
- $0.022 per On Demand SUSE t2.micro instance Hour
- $0.053 per On Demand SUSE t2.small instance Hour
- ちなみに RHEL だと $0.072/1Hour t2.micro
