Installation Overview and Pre-Installation Tasks

This chapter briefly describes how to install JEUS and provides the system requirements and JDK environment configurations for the installation.

1. Overview

JEUS provides a graphical user interface (GUI) that allows easy installation in both UNIX and Windows environments. For UNIX and Linux environments where command-line mode is preferred, installation can be performed in console mode.

The installation file performs the following actions.

  • Displays the JEUS license agreement. Read it carefully, and agree with the terms to install JEUS.

  • Copies JEUS configuration files and directories.

  • Sets JEUS environment variables.

For information about how to install and uninstall JEUS in console mode on UNIX, refer to Installation and Uninstallation.

4. Installing Java JDK

To use JEUS, the Java SE Development Kit (JDK) must be installed.

Ensure that JDK 8, 11, 17, or 21 is installed before installing JEUS. After installation, add the bin directory of the installed JDK to the environment variable PATH.

5. JEUS Licensing

A license key issued by TmaxSoft is required to use JEUS. A trial license is included with the version of JEUS installed by the installer by default. The license file is named 'license' and is in the 'JEUS_HOME/license' directory.

There are two license editions: Standard and Enterprise. They each have different features and license period.

To upgrade a license or to purchase a full license, contact a TmaxSoft sales representative or TmaxSoft directly. To use a license file, copy it to the 'JEUS_HOME/license' directory with the name of 'license'.

If the license file is not named 'license', rename it as 'license'.
