Warning
Do not unpack the archive file into a folder that has any of the following special characters in its path name: #, %, ^, ".

Chapter 3. Adding a Remote Console User

Abstract

The server's remote command console is not configured with a default user. Before you can connect to the server's console remotely, you must add a user to the configuration.

3.1. Add a User

Red Hat JBoss A-MQ is not installed with a default user for the remote console. Before you can remotely manage a server, you must add a user by editing InstallDir/etc/users.properties.
Important
The information in this file is unencrypted so it is not suitable for environments that require strict security.
To add a user:
  1. Open InstallDir/etc/users.properties in your favorite text editor.
  2. Locate the line #admin=admin,admin,manager,viewer,Operator, Maintainer, Deployer, Auditor, Administrator, SuperUser.
    This line specifies a user admin with the password admin and comma-separated list of roles.
  3. Uncomment the line by removing the leading #.
  4. Change the first admin to the desired user name.
  5. Change the second admin to the desired password.
  6. Leave the role list, admin,manager,viewer,Operator, Maintainer, Deployer, Auditor, Administrator, SuperUser, as is.
  7. Save the changes.

Chapter 4. Verifying the Installation

Abstract

Once the installer has completed running it is a good idea to run a simple test to ensure that Red Hat JBoss A-MQ was properly installed.

4.1. Verify the Installation

JBoss A-MQ ships with a simple client utility that can be used to verify that the software was successfully installed. You use it to create a message producer and a message consumer that connect to the broker. If they run successfully, and you see—by checking the Fuse Management Console—that the broker processed the messages, then you can be confident that JBoss A-MQ was installed successfully.
To verify that JBoss A-MQ is properly installed:
  1. Log in as the user with ownership permissions for the JBoss A-MQ installation.
  2. Open a command shell at InstallDir.
  3. Start the broker using the start command.
    Windowsbin\start.bat
    Unix./bin/start
  4. Run the producer client with the following command:
    Linux/UNIX
    ./bin/client "activemq:producer --user Username --password Password"
    Windows
    .\bin\client.bat "activemq:producer --user Username --password Password"
    The producer will connect to the broker and produce 1000 messages. Example 4.1, “Test Producer Output” shows the producer's output.

    Example 4.1. Test Producer Output

    $ ./bin/client "activemq:producer --user Username --password Password"
client: JAVA_HOME not set; results may vary
Logging in as admin
1073 [sshd-SshClient[6575deb1]-nio2-thread-3]
WARN org.apache.sshd.client.keyverifier.AcceptAllServerKeyVerifier -
Server at [/0.0.0.0:8101, DSA, af:77:de:7f:c9:32:f0:b0:ed:12:0e:cd:56:35:fe:78] presented unverified {} key: {}
$
    Note
    The producer command will only send messages to a broker with default port configuration. So, if you set up more than one JBoss A-MQ instance on the same machine, the producer will only send messages to the instance that uses the default ports.
  5. To check that the messages have been enqueued, enter the following command:
    Linux/UNIX
    ./bin/client activemq:dstat
    Windows
    .\bin\client.bat activemq:dstat
  6. Run the consumer client with the following command:
    Linux/UNIX
    ./bin/client "activemq:consumer --user Username --password Password"
    Windows
    .\bin\client.bat "activemq:consumer --user Username --password Password"
    The consumer will connect to the broker and consume 1000 messages. Example 4.2, “Test Consumer Output” shows the consumer's output.

    Example 4.2. Test Consumer Output

    $ ./bin/client "activemq:consumer --user Username --password Password"
client: JAVA_HOME not set; results may vary
Logging in as admin
235 [sshd-SshClient[1d6f6a81]-nio2-thread-1]
WARN org.apache.sshd.client.keyverifier.AcceptAllServerKeyVerifier -
Server at [/0.0.0.0:8101, DSA, af:77:de:7f:c9:32:f0:b0:ed:12:0e:cd:56:35:fe:78] presented unverified {} key: {}
$
  7. To check that the messages have been dequeued, enter the following command:
    Linux/UNIX
    ./bin/client activemq:dstat
    Windows
    .\bin\client.bat activemq:dstat

Chapter 5. Offline Mode

Abstract

You can run the JBoss A-MQ container in offline mode (that is, without an Internet connection). But if you are planning to deploy custom applications to the container, it might be necessary to download additional dependencies (to a local Maven repository) before you can run the container in offline mode with these applications.

5.1. Supported Functionality

If you want to run the JBoss A-MQ container in offline mode, it is necessary to distinguish between the following kinds of dependency:
  • Runtime dependencies—the dependencies required to run the JBoss A-MQ container, in its default configuration.
  • Build-time dependencies—the dependencies required to build a custom application (which might include third-party libraries).
Here is a summary of what can be done in offline mode and what needs to be done in online mode (with an Internet connection):
  • Running the JBoss A-MQ container in its default configuration—is supported in offline mode. The default configuration of the JBoss A-MQ container is specified by the featuresBoot property in the etc/org.apache.karaf.features.cfg file. The requisite dependencies are all provided in the system/ sub-directory of the installation.
  • Installing additional features—is, in general, not supported in offline mode. In principle, you can use the features:install command to install any of the features from the standard feature repositories (as specified by the featuresRepositories property in the etc/org.apache.karaf.features.cfg file), but the majority of these features must be downloaded from the Internet and are thus not supported in offline mode.
  • Deploying custom applications—is, in general, not supported in offline mode. There may be some cases where an application with a minimal set of build-time dependencies is deployable offline, but in general, custom applications would have third-party dependencies that require an Internet connection (so that JAR files can be downloaded by Apache Maven).
If you do need to deploy an application with dependencies that are not available offline, you can use the Maven dependency plug-in to download the application's dependencies into a Maven offline repository. This customized Maven offline repository can then be distributed internally to any machines that do not have an Internet connection. For more details of this approach, see section "Offline Repository for a Maven Project" in "Fabric Guide".

Chapter 6. Installing the Messaging Client Packages

Abstract

Red Hat JBoss A-MQ provides messaging clients as individual packages that you download from the Red Hat Customer Portal.

6.1. Installing Clients on Red Hat Enterprise Linux

Required subscriptions

In order to install the A-MQ client packages on Red Hat Enterprise Linux (RHEL), you require subscriptions to both of the following Red Hat products:
  • Red Hat JBoss A-MQ 6.3
  • RHEL 5, 6, or 7

Qpid JMS AMQP 1.0 Java client

To install the Qpid JMS AMQP 1.0 Java client, enter the following command (as a superuser): 
# yum install qpid-jms-client qpid-jms-client-docs qpid-jms-client-examples qpid-jms-client-maven-repo

Qpid C++ client

To install the Qpid C++ client, enter the following command (as a superuser): 
# yum install qpid-cpp-client qpid-cpp-client-devel
Important
The Qpid C++ client packages are currently not available for the following platform (processor) combinations: RHEL 5 (i686) and RHEL 6 (i686).

Python language bindings for Qpid Proton

To install the Python language bindings for the Qpid Proton messaging framework, enter the following command (as a superuser): 
# yum install python-qpid-proton python-qpid-proton-doc

Compiling the Qpid C++ client from sources on RHEL 6

The Qpid C++ client cannot be compiled from sources through the Client or ComputeNode channels on RHEL 6 (due to a missing dependency on the package, nss-devel). In order to compile from sources, it is recommended that you install the Qpid C++ client through the Server channel instead.
