Java is a powerful programming language. Software written in Java can compile and run on any system. Unlike Python or C, Java does not come pre-installed on Linode distribution images. This guide installs the OpenJDK 8 runtime environment and development kit in CentOS 7. OpenJDK is the free and open-source implementation of the Java SE Development Kit.

Before You Begin

  1. Familiarize yourself with our Getting Started guide and complete the steps for setting your Linode’s hostname and timezone.

  2. This guide will use sudo wherever possible.

  3. Update your system:

    sudo yum update

Install Java Runtime Environment (Java JRE)

If you don’t plan on using Java to write software, the JRE is all you need. In CentOS, the JRE package is java-$(version)-openjdk. The openjdk-headless package contains a minimal implementation of the JDK for executing Java applications on the command line. In this example, you’ll install the minimal version of OpenJDK 8.

sudo yum install java-1.8.0-openjdk-headless

After the installation finishes, verify its completion using yum list installed | grep "java". The output should be:

java-1.8.0-openjdk-headless.x86_64   1:1.8.0.131-3.b12.el7_3           @updates
javapackages-tools.noarch            3.4.1-11.el7                      @base
python-javapackages.noarch           3.4.1-11.el7                      @base
tzdata-java.noarch                   2017b-1.el7                       @updates

Install the Java Development Kit (Java JDK)

If you plan on using Java to write or edit programs on your Linode, install the JDK.

sudo yum install java-1.8.0-openjdk-devel

After the installation finishes, verify its completion using yum list installed | grep "openjdk-devel". The output should be:

java-1.8.0-openjdk-devel.x86_64      1:1.8.0.131-3.b12.el7_3           @updates

You can also verify by running the Java compiler, javac. If you need to compile Java code on your Linode, run javac foobar.java. Then, run the application with java foobar.
