圧縮ファイルを展開

$ tar xzvf openjdk-11.0.2_linux-x64_bin.tar.gz jdk-11.0.2/bin/jaotc jdk-11.0.2/bin/jar jdk-11.0.2/bin/jarsigner jdk-11.0.2/bin/java jdk-11.0.2/bin/javac jdk-11.0.2/bin/javadoc jdk-11.0.2/bin/javap ： ： |
展開したディレクトリを/optへ移動
|
|
$ sudo mv jdk-11.0.2/ /opt/ |
デフォルトではOpenJDK7が入っていた為 java、jar、javacコマンドをalternativesで切り替え
|
|
$ sudo alternatives --install /usr/bin/java java /opt/jdk-11.0.2/bin/java 1 $ sudo alternatives --install /usr/bin/jar jar /opt/jdk-11.0.2/bin/jar 1 $ sudo alternatives --install /usr/bin/javac javac /opt/jdk-11.0.2/bin/javac 1 |
バージョン確認
|
|
$ java -version java version "1.7.0_231" OpenJDK Runtime Environment (amzn-2.6.19.1.80.amzn1-x86_64 u231-b01) OpenJDK 64-Bit Server VM (build 24.231-b01, mixed mode) |
……うまく切り替わっていなかった為再設定。
|
|
$ sudo alternatives --config java There are 2 programs which provide 'java'. Selection Command ----------------------------------------------- *+ 1 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java 2 /opt/jdk-11.0.2/bin/java Enter to keep the current selection[+], or type selection number: |
/opt/～に配置されている11.0.2を使用する為2を入力しEnter
その後再度コマンドで確認。
|
|
$ java -version openjdk version "11.0.2" 2019-01-15 OpenJDK Runtime Environment 18.9 (build 11.0.2+9) OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode) $ jar --version jar 11.0.2 $ javac -version javac 11.0.2 |
最初に取得した11.0.2が設定されていることを確認。
