Automating the Oracle JDK installation on RHEL derivatives (such as CentOS, Oracle Linux) and Debian derivatives (such as Mint, Ubuntu) differs. This is due to different package managers and repositories. In this blog I’ll provide quick instructions on how to automate the installation of Oracle JDK 8 and 10 on different Linux distributions. I chose JDK 8 and 10 since they are currently the only Oracle JDK versions which receive public updates (see here).

Debian derivatives

Benefit of using the below repositories is that you will often get the latest version and can easily update to the latest version in an existing installation if you want.

Oracle JDK 8

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo echo debconf shared/accepted-oracle-license-v1-1 select true | sudo debconf-set-selections
sudo echo debconf shared/accepted-oracle-license-v1-1 seen true | sudo debconf-set-selections
sudo apt-get -y install oracle-java8-installer
sudo apt-get -y install oracle-java8-set-default

Oracle JDK 10

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo echo debconf shared/accepted-oracle-license-v1-1 select true | sudo debconf-set-selections
sudo echo debconf shared/accepted-oracle-license-v1-1 seen true | sudo debconf-set-selections
sudo apt-get -y install oracle-java10-installer
sudo apt-get -y install oracle-java10-set-default

RHEL derivatives

Since RHEL derivatives are often provided by commercial software vendors such as RedHat and Oracle, they like to work on a subscription basis for their repositories since people pay for using them. Configuration of the specific repositories and subscriptions of course differs per vendor and product. For Oracle Linux you can look here. For RedHat you can look here.

The below described procedure makes you independent of vendor specific subscriptions, however you will not gain automatic updates and if you want to have the latest version you have to manually update the download URL from here and update the Java installation path in the alternatives commands. You also might encounter issues with the validity of the used cookie which might require you to update the URL.

Oracle JDK 8

sudo wget -O ~/jdk8.rpm -N --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u181-b13/96a7b8442fe848ef90c96a2fad6ed6d1/jdk-8u181-linux-x64.rpm
sudo yum -y localinstall ~/jdk8.rpm
sudo update-alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_181-amd64/jre/bin/java 1
sudo update-alternatives --install /usr/bin/jar jar /usr/java/jdk1.8.0_181-amd64/bin/jar 1
sudo update-alternatives --install /usr/bin/javac javac /usr/java/jdk1.8.0_181-amd64/bin/javac 1
sudo update-alternatives --install /usr/bin/javaws javaws /usr/java/jdk1.8.0_181-amd64/jre/bin/javaws 1

Oracle JDK 10

sudo wget -O ~/jdk10.rpm -N --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/10.0.2+13/19aef61b38124481863b1413dce1855f/jdk-10.0.2_linux-x64_bin.rpm
sudo yum -y localinstall ~/jdk10.rpm
sudo update-alternatives --install /usr/bin/java java /usr/java/jdk-10.0.2/bin/java 1
sudo update-alternatives --install /usr/bin/jar jar /usr/java/jdk-10.0.2/bin/jar 1
sudo update-alternatives --install /usr/bin/javac javac /usr/java/jdk-10.0.2/bin/javac 1
sudo update-alternatives --install /usr/bin/javaws javaws /usr/java/jdk-10.0.2/bin/javaws 1
