4.2. Using the installer in CLI mode

You can run the Red Hat Decision Manager installer through the command-line interface (CLI).

注記

For security reasons, you should run the installer as a non-root user.

Prerequisites

A supported JDK is installed. For a list of supported JDKs, see Red Hat Process Automation Manager 7 Supported Configurations.
A backed-up Red Hat JBoss EAP 7.2 server installation is available.
Sufficient user permissions to complete the installation are granted.
The JAR binary is included in the $PATH environment variable. On Red Hat Enterprise Linux, it is included in the java-$JAVA_VERSION-openjdk-devel package.
注記
Red Hat Decision Manager is designed to work with UTF-8 encoding. If a different encoding system is used by the underlying JVM, unexpected errors might occur. To ensure UTF-8 is used by the JVM, use the "-Dfile.encoding=UTF-8" system property.

Procedure

Read the license agreement, enter 1, and press Enter to continue:

Specify the home directory of one of the following servers:  Red Hat JBoss EAP 7.2 or Red Hat JBoss Web Server 5.1.0

Enter the parent directory of an existing Red Hat JBoss EAP 7.2 installation.
The installer will verify the location of the installation at the location provided. Enter 1 to confirm and continue.
注記
You can install Business Central and Decision Server on the same server. However, you should install Business Central and Decision Server on different servers in production environments.
Follow the instructions in the installer to complete the installation.
注記
When you create the user name and password, make sure that the specified user name does not conflict with any known title of a role or a group. For example, if there is a role called admin, you should not create a user with the user name admin.
The password must have at least eight characters and must contain at least one number and one non-alphanumeric character (not including the character &).
Make a note of the user name and password. You will need them to access Business Central and Decision Server.

When the installation has completed, you will see this message:

Would you like to generate an automatic installation script and properties file?

Enter y to create XML files that contain the installation data, or n to complete the installation. If you enter y, you are prompted to specify a path for the XML files.
Enter a path or press the Enter key to accept the suggested path.
The installer generates two files. The auto.xml file automates future installations and the auto.xml.variables file stores user passwords and other sensitive variables. Use the auto.xml file on multiple systems to easily repeat a Red Hat Decision Manager installation on the same type of server with the same configuration as the original installation. If necessary, update the installpath parameter in the auto.xml file. Enter the following command to perform an installation with the XML file:
```
java -jar rhdm-installer-7.5.1.jar <path-to-auto.xml-file>
```
If you installed only Business Central, repeat these steps to install Decision Server on a separate server.
