Setting environment variables
JEUS requires the following system environment variables. These variables are applied during the installation. The environment variable PATH is recorded in the environment variable files .profile, .cshrc, etc., and the remaining environment variables are set in the $JEUS_HOME/bin/jeus.properties file.
- By default, it is automatically added to the default shell when installing
Environment variable | Description | Setting value |

PATH | System path | This should contain: |
JEUS_LIBPATH | JEUS library file | $JEUS_HOME/lib/system |
JEUS_HOME | JEUS installation directory | $HOME/jeus6/ |
JEUS_BASSPORT | The most basic port to use for JEUS (default: 9763) | 9763 |

Confirming if JEUS has started
To confirm that JEUS installation is completed normally, perform the following steps.
Type “jeus” at the console prompt.
1. When the message “JEUS Manager is READY” is displayed, it indicates that JEUS Manager is properly loaded and that JEUS is in standby.
2. Run jeusadmin <node name> in another console window. Here, <node name> is the host machine name. The password for logging in can be accessed using the password specified when installing JEUS.
3. After login into the jeusadmin tool, the user can control the JEUS server with commands such as boot and down.
If the message “connect successful” is displayed, JEUS is booted properly.
When the message “all containers successfully shutdown” is displayed, JEUS is down normally.
4. After JEUS is started, check the process.
Considerations when installing JEUS
This section describes the considerations when installing JEUS.
1. An error occurs if the wrong operating system is selected.
If operating system that does not fit the characteristics of the server is selected in the step of selecting the operating system when installing JEUS, installation will not be possible.
Ex) When Linux x86 is selected on a Linux x64 device
2. When the GLIBC version is low
If the GLIBC version of the server is lower than 2.4, an error occurs during installation. The version of GBLIC can be checked by the following command.
Ex) GLIBC version is 2.3
