Java herunterladen:
- JRE: http://java.com/de/download/linux_manual.jsp
- JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html
Installation
Falls folgendes Verzeichnis nicht existiert, dann dieses anlegen:
sudo mkdir /opt/Oracle_Java/
wget download.oracle.com/otn-pub/java/jdk/8u92-b14/jdk-8u92-linux-x64.tar.gz tar -xzf jdk-8u92-linux-x64.tar.gz sudo mv jdk1.8.0_92/ /opt/Oracle_Java/ sudo chown -R root:root /opt/Oracle_Java/jdk1.8.0_92/
Alternativen-System einrichten:
sudo update-alternatives --install "/usr/bin/java" "java" "/opt/Oracle_Java/jdk1.8.0_92/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/opt/Oracle_Java/jdk1.8.0_92/bin/javac" 1 sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/opt/Oracle_Java/jdk1.8.0_92/bin/javaws" 1 sudo update-alternatives --install "/usr/bin/jar" "jar" "/opt/Oracle_Java/jdk1.8.0_92/bin/jar" 1
Alternativen-System konfigurieren:
sudo update-alternatives --set "java" "/opt/Oracle_Java/jdk1.8.0_92/bin/java" sudo update-alternatives --set "javac" "/opt/Oracle_Java/jdk1.8.0_92/bin/javac" sudo update-alternatives --set "javaws" "/opt/Oracle_Java/jdk1.8.0_92/bin/javaws" sudo update-alternatives --set "jar" "/opt/Oracle_Java/jdk1.8.0_92/bin/jar"
OpenJDK
OpenJDK 1.11
Installation
sudo apt-get install -y openjdk-11-jre openjdk-11-jdk openjdk-11-demo openjdk-11-doc openjdk-11-jre-headless openjdk-11-source
VirtualBox / XUbuntu / the trustAnchors parameter must be non-empty
Edit
sudo vi /etc/java-11-openjdk/security/java.security
and replace line keystore.type = pkcs12 with keystore.type = jks.
Than call
sudo rm /etc/ssl/certs/java/cacerts file sduo update-ca-certificates -f
OpenJDK 1.9
Installation
sudo apt-get install openjdk-9-jdk openjdk-9-demo openjdk-9-doc openjdk-9-jre openjdk-9-jre-headless openjdk-9-source
OpenJDK 1.8
Installation
sudo apt-get install openjdk-8-jre openjdk-8-jre-headless icedtea-8-plugin openjdk-8-jdk openjdk-8-demo openjdk-8-doc openjdk-8-source
Source
Installation:
sudo apt-get install openjdk-8-source
Speicherort:
/usr/lib/jvm/openjdk-8/src.zip
OpenJDK 1.7
Installation
Da OpenJDK 1.7 in Ubuntu 16.04 LTS nicht mehr unterstützt wird, muss eine frühere Paketquelle (in dem Fall 12.04 LTS) hinzugefügt werden:
sudo nano /etc/apt/sources.list
In /etc/apt/sources.list am Ende folgende Zeile hinzufügen:
deb http://security.ubuntu.com/ubuntu precise-security main universe
Bevor OpenJDK 1.7 installiert werden kann, müssen noch ein paar Abhängigkeiten manuell installiert werden:
wget http://launchpadlibrarian.net/159902387/libgif4_4.1.6-11_amd64.deb sudo apt install /home/martin/Downloads/libgif4_4.1.6-11_amd64.deb wget http://security.ubuntu.com/ubuntu/pool/main/t/tzdata/tzdata_2016d-0ubuntu0.12.04_all.deb sudo apt install /home/martin/Downloads/tzdata_2016d-0ubuntu0.12.04_all.deb wget http://security.ubuntu.com/ubuntu/pool/main/t/tzdata/tzdata-java_2016d-0ubuntu0.12.04_all.deb sudo apt install /home/martin/Downloads/tzdata-java_2016d-0ubuntu0.12.04_all.deb
Danach die eigentlichen Pakete installieren:
sudo apt-get install openjdk-7-jre openjdk-7-jdk openjdk-7-demo openjdk-7-doc openjdk-7-jre-headless openjdk-7-jre-lib openjdk-7-source
Deinstallation
sudo apt-get remove openjdk-7*
