Description

Installs a Java. Uses OpenJDK by default but supports installation of Oracle's JDK.

This cookbook also provides the java_ark LWRP which other java cookbooks can use to install java-related applications from binary packages.

The java_ark LWPR may move to its own cookbook at some point in the future as its functionality is useful for other purposes.

Requirements

Platform

• Debian, Ubuntu
• CentOS, Red Hat, Fedora, Scientific, Amazon
• ArchLinux
• FreeBSD

Attributes

See attributes/default.rb for default values.

• node["java"]["install_flavor"] - Flavor of JVM you would like installed (oracle or openjdk), default openjdk.
• node['java']['java_home'] - Default location of the "$JAVA_HOME".
• node['java']['tarball'] - name of the tarball to retrieve from your corporate repository default jdk1.6.0_29_i386.tar.gz
• node['java']['tarball_checksum'] - checksum for the tarball, if you use a different tarball, you also need to create a new sha256 checksum
• node['java']['jdk'] - version and architecture specific attributes for setting the URL on Oracle's site for the JDK, and the checksum of the .tar.gz.

Recipes

default

Include the default recipe in a run list, to get java. By default the openjdk flavor of Java is installed, but this can be changed by using the install_flavor attribute.

OpenJDK is the default because of licensing changes made upstream by Oracle. See notes on the oracle recipe below.

openjdk

This recipe installs the openjdk flavor of Java.

oracle

This recipe installs the oracle flavor of Java. This recipe does not use distribution packages as Oracle changed the licensing terms with JDK 1.6u27 and prohibited the practice for both the debian and EL worlds.

For both debian and centos/rhel, this recipe pulls the binary distribution from the Oracle website, and installs it in the default JAVA_HOME for each distribution. For debian/ubuntu, this is /usr/lib/jvm/default-java. For Centos/RHEL, this is /usr/lib/jvm/java

After putting the binaries in place, the oracle recipe updates /usr/bin/java to point to the installed JDK using the update-alternatives script

oracle_i386

This recipe installs the 32-bit Java virtual machine without setting it as the default. This can be useful if you have applications on the same machine that require different versions of the JVM.

Resources/Providers

This LWRP provides an easy way to manage java applications. It uses the LWRP arkive (deliberately misspelled). It is an arkive and not an "archive" because the java_ark lwrp is not the same as a java archive or "jar". Essentially, you provide the java_ark with the URL to a tarball and the commands within the extracted result that you want symlinked to /usr/bin/

The java_ark LWPR may move to its own cookbook at some point in the future as its functionality is useful for other purposes.

By default, the extracted directory is extracted to app_root/extracted_dir_name and symlinked to app_root/default

Actions

• :install: extracts the tarball and makes necessary symlinks
• :remove: removes the tarball and run update-alternatives for all symlinked bin_cmds

Attribute Parameters

• url: path to tarball, .tar.gz, .bin (oracle-specific), and .zip currently supported
• checksum: sha256 checksum, not used for security but avoid redownloading the archive on each chef-client run
• app_home: the default for installations of this type of application, for example, /usr/lib/tomcat/default. If your application is not set to the default, it will be placed at the same level in the directory hierarchy but the directory name will be app_root/extracted_directory_name + "_alt"
• app_home_mode: file mode for app_home, is an integer
• bin_cmds: array of binary commands that should be symlinked to /usr/bin, examples are mvn, java, javac, etc. These cmds must be in the bin/ subdirectory of the extracted folder. Will be ignored if this java_ark is not the default
• owner: owner of extracted directory, set to "root" by default
• default: whether this the default installation of this package, boolean true or false

Examples

# install jdk6 from Oracle
java_ark "jdk" do
    url 'http://download.oracle.com/otn-pub/java/jdk/6u29-b11/jdk-6u29-linux-x64.bin'
    checksum  'a8603fa62045ce2164b26f7c04859cd548ffe0e33bfc979d9fa73df42e3b3365'
    app_home '/usr/local/java/default'
    bin_cmds ["java", "javac"]
    action :install
end

# installs maven2
java_ark "maven2" do
    url "http://www.apache.org/dist/maven/binaries/apache-maven-2.2.1-bin.tar.gz"
    checksum  "b9a36559486a862abfc7fb2064fd1429f20333caae95ac51215d06d72c02d376"
    app_home "/usr/local/maven/default"
    bin_cmds ["mvn"]
    action :install
end

Usage

Simply include the java recipe where ever you would like Java installed.

To install Oracle flavored Java on Debian or Ubuntu override the node['java']['install_flavor'] attribute with in role:

name "java"
description "Install Oracle Java on Ubuntu"
override_attributes(
  "java" => {
    "install_flavor" => "oracle"
  }
)
run_list(
  "recipe[java]"
)
