4 Installation of the JDK on Linux Platforms
This topic describes the installation procedures of the JDK on the Linux platform, along with the system requirements.
General Notes About Installing the JDK on Linux Platforms
Root Access
This topic describes general information about installing JDK 11 on Linux platforms.Installing the JDK automatically creates a directory called jdk–11.interim.update.patch
.
Note:
If you install Java SE Runtime Environment in a specific location such as /usr/jdk
(for JDK) then you must log in with root credentials to gain the necessary permissions. If you do not have root access, then either install the Java SE Runtime Environment in your home directory or a subdirectory for which you have write permissions.
Overwriting Files
If you install the software in a directory that contains a subdirectory named jdk–11.interim.update.patch
, then the new software overwrites files of the same name in that directory. Ensure that you rename the old directory if it contains files that you would like to keep.
System Preferences
By default, the installation script configures the system such that the backing store for system preferences is created inside the JDK installation directory as applicable. If the JDK is installed on a network-mounted drive, then the system preferences can be exported for sharing with Java runtime environments on other machines.
System Requirements for Installing JDK on Linux Platforms
See Oracle JDK Certified Systems Configurations for information about supported platforms, operating systems, and browsers.
JDK Installation Instruction Notation for Linux Platforms
Instructions for installing JDK contains a version notation that represents the Feature, Interim, and Update version information.
For example, if you are installing JDK 11 Interim 0, Update 0, and Patch 0, then the following string represents the name of the bundle:
Linux x64 systems: jdk-11.interim.update.patch_linux-x64_bin.tar.gz
jdk-11_linux-x64_bin.tar.gz
Linux aarch64 (64-bit ARM) systems: jdk-11.interim.update.patch_linux-aarch64_bin.tar.gz
jdk-11_linux-aarch64_bin.tar.gz
Note:
If a component has 0 as the suffix, it will be excluded.Installing the JDK on Linux from Archive Files and RPM Packages
You can install the Java Development Kit (JDK) on a Linux platform from archive files or from Red Hat Package Manager (RPM) packages.
Installation can be performed by using one of the following processes:
-
From archive files (
.tar.gz
): This allows you to install a private version of the JDK for the current user into any location, without affecting other JDK installations. However, it may involve manual steps to get some of the features to work. See the following table for the options available for downloading and installing the JDK from archive files. The bundles are available for Linux x64 and Linux aarch64 (64-bit ARM) systems. Install the required bundle. -
From RPM packages (
.rpm
): This allows you to perform a systemwide installation of the JDK for all users, and requires root access. See the following table for the options available for downloading and installing the JDK from Linux x64 and Linux aarch64 (64-bit ARM) RPM packages.
Downloading the JDK Installer
Access Java SE Downloads page and click Accept License Agreement. Under the Download menu, click the Download link corresponding your requirement.
The following table lists the options and instructions for downloading and installing the JDK 11 release on a Linux platform:
Download File | Instructions | Architecture (CPU Type) | Who Can Install |
---|---|---|---|
For Linux x64 systems: jdk-11.interim.update.patch_linux-x64.tar.gz |
Installing the 64-Bit JDK 11 on Linux Platforms | Intel - 64-bit | Anyone |
For Linux aarch64 (64-bit ARM) systems:
jdk-11.interim.update.patch_linux-aarch64.tar.gz |
Installing the 64-Bit JDK 11 on Linux Platforms | ARM - 64-bit | Anyone |
For Linux x64 systems: jdk-11.interim.update.patch_linux-x64.rpm |
Installing the 64-Bit JDK on RPM-Based Linux Platforms | Intel - 64-bit RPM-based Linux | Root |
For Linux aarch64 (64-bit ARM) systems:
jdk-11.interim.update.patch_linux-aarch64.rpm |
Installing the 64-Bit JDK on RPM-Based Linux Platforms | ARM - 64-bit RPM-based Linux | Root |
Installing the 64-Bit JDK 11 on Linux Platforms
You can install the JDK for 64-bit Linux from an archive file
(.tar.gz
). The .tar.gz
archive file (also called a
tarball) is a file that can be uncompressed and extracted in a single step.
Installing the 64-Bit JDK on RPM-Based Linux Platforms
You can install the JDK on 64-bit RPM-based Linux platforms, such as Oracle,
Red Hat, and SuSE by using an RPM binary file (.rpm
) in the system location.
su
and entering the superuser password.
The JDK installation is integrated with the alternatives framework. After installation, the alternatives framework is updated to reflect the binaries from the recently installed JDK. Java commands such as java
, javac
, javadoc
, and javap
can be called from the command line.
Using the java -version
command, users can confirm the default (recently installed) JDK version.
In addition, users can check which specific RPM package provides the
java
files:
$ rpm -q --whatprovides java
