Overview

Installs the correct Java package on various platforms.

Module Description

The java module can automatically install Java jdk or jre on a wide variety of systems. Java is a base component for many software platforms, but Java system packages don't always follow packaging conventions. The java module simplifies the Java installation process.

Setup

Beginning with the java module

To install the correct Java package on your system, include the java class: include java.

Usage

The java module installs the correct jdk or jre package on a wide variety of systems. By default, the module installs the jdk package, but you can set different installation parameters as needed. For example, to install jre instead of jdk, you would set the distribution parameter:

class { 'java':
  distribution => 'jre',
}

To install the latest patch version of Java 8 on CentOS

class { 'java' :
  package => 'java-1.8.0-openjdk-devel',
}

The defined type java::download installs one or more versions of Java SE from a remote url. java::download depends on puppet/archive.

To install Java to a non-default basedir (defaults: /usr/lib/jvm for Debian; /usr/java for RedHat):

java::download { 'jdk8' :
  ensure  => 'present',
  java_se => 'jdk',
  url     => 'http://myjava.repository/java.tgz",
  basedir => '/custom/java',
}

Reference

For information on the classes and types, see the REFERENCE.md. For information on the facts, see below.

Facts

The java module includes a few facts to describe the version of Java installed on the system:

• java_major_version: The major version of Java.
• java_patch_level: The patch level of Java.
• java_version: The full Java version string.
• java_default_home: The absolute path to the java system home directory (only available on Linux). For instance, the java executable's path would be ${::java_default_home}/jre/bin/java. This is slightly different from the "standard" JAVA_HOME environment variable.
• java_libjvm_path: The absolute path to the directory containing the shared library libjvm.so (only available on Linux). Useful for setting LD_LIBRARY_PATH or configuring the dynamic linker.

Note: The facts return nil if Java is not installed on the system.

Limitations

For an extensive list of supported operating systems, see metadata.json

This module cannot guarantee installation of Java versions that are not available on platform repositories.

This module only manages a singular installation of Java, meaning it is not possible to manage e.g. OpenJDK 7, Oracle Java 7 and Oracle Java 8 in parallel on the same system.

Oracle Java packages are not included in Debian 7 and Ubuntu 12.04/14.04 repositories. To install Java on those systems, you'll need to package Oracle JDK/JRE, and then the module can install the package. For more information on how to package Oracle JDK/JRE, see the Debian wiki.

This module is officially supported for the following Java versions and platforms:

OpenJDK is supported on:

• Red Hat Enterprise Linux (RHEL) 5, 6, 7
• CentOS 5, 6, 7
• Oracle Linux 6, 7
• Scientific Linux 6
• Debian 8, 9
• Ubuntu 14.04, 16.04, 18.04
• Solaris 11
• SLES 11, 12

Sun Java is supported on:

• Debian 6

Oracle Java is supported on:

• CentOS 6
• CentOS 7
• Red Hat Enterprise Linux (RHEL) 7

Known issues

Where Oracle change the format of the URLs to different installer packages, the curl to fetch the package may fail with a HTTP/404 error. In this case, passing a full known good URL using the url parameter will allow the module to still be able to install specific versions of the JRE/JDK. Note the version_major and version_minor parameters must be passed and must match the version downloaded using the known URL in the url parameter.

OpenBSD

OpenBSD packages install Java JRE/JDK in a unique directory structure, not linking the binaries to a standard directory. Because of that, the path to this location is hardcoded in the java_version fact. Whenever you upgrade Java to a newer version, you have to update the path in this fact.

Development

Puppet modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. To contribute to Puppet projects, see our module contribution guide.
