Chapter 2. Installing Red Hat JBoss Fuse as a Service

Abstract

The Red Hat JBoss Fuse installer generates a service wrapper that can be easily configured to install JBoss Fuse as a system service.
Installing Red Hat JBoss Fuse as a system service is a three-step process:
  1. Generate the service wrapper for your system.
  2. Configure the service wrapper for your system.
  3. Install the service wrapper as system service.

2.1. Generating the Service Wrapper

Abstract

The service wrapper is generated using an optional feature of the command console. Once installed the feature will generate the appropriate start-up scripts, configuration, an libraries to install a broker as a system service.

Overview

The Red Hat JBoss Fuse console's wrapper feature generates a wrapper around the JBoss Fuse runtime that allows you to install a message broker as a system service. The wrapper feature does not come preinstalled in the console, so before you can generate the service wrapper you must install the wrapper feature.
Once the feature is installed the console gains a wrapper:install command. Running this command generates a generic service wrapper in the JBoss Fuse installation.

Procedure

To generate the service wrapper:
  1. Start JBoss Fuse in console mode using the fuse command.
  2. Once the console is started and the command prompt appears, enter features:install wrapper.
    The features:install command will locate the required libraries to provision the wrapper feature and deploy it into the run time.
  3. Generate the wrapper by entering wrapper:install -n serviceName -d displayName -D description.
    The wrapper:install command has the options described in Table 2.1, “Wrapper Install Options”.

    Table 2.1. Wrapper Install Options

    OptionDefaultDescription
    -sAUTO_STARTSpecifies the mode in which the service is installed. Valid values are AUTO_START or DEMAND_START.
    -nkarafSpecifies the service name that will be used when installing the service.
    -d Specifies the display name of the service.
    -D Specifies the description of the service.

Generated files

The following files are generated and make up the service wrapper:
  • etc\ServiceName-wrapper(.exe)—the executable file for the wrapper.
  • bin\ServiceName-service(.bat)—the script used to install and remove the service.
  • etc\ServiceName-wrapper.conf—the wrapper's configuration file.
  • Three library files required by the service wrapper:
    • lib\libwrapper.so
    • lib\karaf-wrapper.jar
    • lib\karaf-wrapper-main.jar
Important
The only generated file you should modify is the configuration file.
