Amazon Linux上にSun JDK 1.7を入れてみた。

Amazon Linux AMI上でSun JDK 1.7を入れるのにちょっと苦労したのでメモ。

2012/11/14追記：
⇒ Amazon Linux上にSun JDK 1.7を入れてみた。(修正) にて再修正したやり方を書いています。
(下のやり方をした場合、/usr/lib/jvm/jreが正常に作成されないため、JAVA_HOME環境変数が自動設定されなくなります)

Sun Java SE (JDK)のダウンロード

http://www.oracle.com/technetwork/java/javase/downloads/index.html あたりからJavaScriptが動くブラウザを使ってダウンロードしておく。
# w3mやlynxからは上手くいかないので注意。

rpmのインストール

上でダウンロードしてきたrpmをインストールする。
root# rpm -ivh jdk-7u9-linux-x64.rpm
