System requirements

JIRA requires a Java Developers Kit (JDK) or Java Runtime Environment (JRE) platform to be installed on your server's operating system.

Procedure to install the JDK

If you install JIRA from an archive file then the JDK needs to be installed and set up separately on your system. The Windows Installer and Linux Installer don't need to install the JDK as these installers come with the JDK in-built.

You can download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html.

Select the version relevant to your operating system and architecture. JIRA 7 requires JDK 1.8 to run smoothly.

The steps to install the JDK on Windows are as follows:

1. Uninstall any earlier version of Java that was installed on your system.
2. Restart your system.
3. Using the downloaded installer, you can install the JDK at C:\java (don't install it in C:\Program Files\). The JDK specific directory, such as C:\Java\jdk1.8.0_92, will be created.
4. Set the JAVA_HOME windows environment variable. It should point to the directory where JDK is installed, C:\Java\jdk1.8.0_92, on the Windows machine.
5. Restart your system.

Steps to install the JDK on Linux

Using the link given in the preceding section, download the JDK RPM installer, jdk-8u92-linux-x64.rpm, and install it at a location of your choice.

Set the JAVA_HOME variable as export JAVA_HOME = /path/to/java.
