Installing the Messaging Server: DEPRECATED

Prerequisites

Before starting the Messaging Server installation, the Application Server (appserver) should be installed.

Download the Messaging Server

1. Download the messaging server https://agileappscloud.info/aadev-src/download/files/messaging-server.tar.gz

2. Unpack the archive to the application server directory.
   For example:

   cd {appserver}/

   gunzip messaging-server.tar.gz

   tar xfz messaging-server.tar

Install HornetQ

HornetQ is the Message Queue engine used by the Messaging Server.

To install HornetQ:

1. Download the release specified in the Software Requirements from
   http://www.jboss.org/hornetq/downloads.html

2. Unpack the archive to the desired location.
   For example:

   cd {appserver}/

   tar xfz hornetQ-{version}.tar

3. Edit {hornetq_install}/config/stand-alone/non-clustered/hornetq-users.xml
   Add the following code to the <configuration> section to create the admin user who will have access to the queue:

   <syntaxhighlight lang="xml" enclose="div">

<user name="[USER_NAME]" password="[PASSWORD]">

  <role name="admin"/>

</user> </syntaxhighlight>

1. Edit {hornetq_install}/config/stand-alone/non-clustered/hornetq-configuration.xml
   Replace the <security>...</security> section with the following:

   <syntaxhighlight lang="xml" enclose="div">

<security-settings>

  <security-setting match="#">
     <permission type="createNonDurableQueue" roles="guest, admin"/>
     <permission type="deleteNonDurableQueue" roles="guest, admin"/>
     <permission type="createDurableQueue" roles="admin"/>
     <permission type="deleteDurableQueue" roles="admin"/>
     <permission type="consume" roles="guest, admin"/>
     <permission type="send" roles="guest, admin"/>
     <permission type="manage" roles="admin"/>
  </security-setting>

</security-settings> </syntaxhighlight>

Start HornetQ

Start HornetQ before proceeding with the next step in the installation:

{hornetq_install}/bin/run.sh

Note: HornetQ should always be started before launching the platform's messaging server. Learn more: Server Restart Sequence

Configure the Platform's Service Provider Settings

1. Go to the Service Provider URL: http://{yourDomain}/networking/Service?t=1&targetpage=ViewPort.jsp
2. Log in as the admin user
3. Go to Settings > Service Provider Settings > Service Configuration
4. Set values for the following parameters:

HornetQ Host	IP address of the server where HornetQ is installed  (If running on the same server as the messaging server, enter localhost)
HornetQ Port	Default: 5445.  Needs to be specified only if the port specified for the netty acceptor  was changed in hornetq-configuration.xml
HornetQ User HornetQ Password	Use the same credentials you specified in hornetq-users.xml
HornetQ QoS	The number of simultaneously working Message Queue listeners.  (A typical value is 2.)

5. Click [Save]

6. Restart the server to read the new configuration:

1. Login as root
2. {install-dir}/profiles/IS_default/bin/restart.sh

Create an SSL Keystore

The Messaging Server accepts only SSL-encrypted connections. It needs a valid SSL certificate to perform a Handshake and data exchange with client systems.

The same Java keystore, SSL certificate, and private key used for the application server can be used for the Messaging Server. So once that has been set up, nothing else needs to be done.

Learn more: Managing SSL Certificates.

Configure the Messaging Server

1. Start the appserver:

   {appserver}/profiles/LJP/bin/startup.sh

2. Go to {appserver}/messaging-server/conf/.
   That directory contains two configuration files:

   • log4j.properties – standard Apache Log4J configuration file.
   • server.properties – Messaging Server configuration file.

3. In server.properties, configure the following parameters:
   • netty_port

     Use 443 if it is on a standalone system.

     If is on the same system as the appserver, then:

     • Use the default value (7443)
     • Add Apache Web Server proxy instructions (see end of document)

   • debug – set value to 1 to see content of all incoming HTTP requests in the log.

     Otherwise, use the default value (0).

   • ssl_keystore – absolute or relative path to your SSL keystore
   • ssl_keystore_password – password for your SSL keystore
   • customer_db_server - put proper values for host, username and password to connect to the platform's MySQL Database
   • message_db_server - put proper values for host, username and password to connect to the Messaging Server Database.
     If the Messaging Server doesn't have a separate MySQL instance, copy the value of customer_db_server

4. In platform's Service Provider Settings, set the Messaging Server Host parameter to the messaging server's hostname (or IP address) and port. For example, hostname:7443.

AppServer Installation

Follow these steps when running the Messaging Server on the same system as an appserver:

1. Copy the messaging script to its target destination:

   cp {appserver_installation}/messaging-server/messaging /etc/init.d/

2. Make messaging an autostart script:

   cd /etc/init.d/

   chkconfig –add messaging

Standalone Installation

For maximum performance, follow these steps to run the Messaging Server on a standalone system:

1. Install MySQL on the Messaging Server instance. Use the same MySQL credentials as on the appserver.
2. Import messagingdb.sql into MySQL on the Messaging Server system.

   Note:
   The MySQL instance used by the Messaging Server contains real-time data, only. There is no need for backups or database replication, as the data structures can be easily restored by re-running that SQL script.

3. Copy quartz-2.2.1.jar, quartz-jobs-2.2.1.jar, gf.jettison-1.1.jar, and jgroups-3.6.11.Final.jar from ..\Agileapps\lib folder to $messaging-server$/lib folder.
4. Add :lib/quartz-2.2.1.jar:lib/quartz-jobs-2.2.1.jar:lib/gf.jettison-1.1.jar:lib/jgroups-3.6.11.Final.jar into the path of startmessaging.sh and save the file.
5. Verify if mysql-connector-java-5.1.24-bin.jar file is present in the $messaging-server$/lib folder. If not, copy the mysql-connector-java-5.1.24-bin.jar file into this path.
6. Copy these files from the appserver system to the Messaging Server system:
   • Copy the entire messaging-server directory to the installation directory.
   • Copy es.jar from the platform's tomcat/lib to messaging-server/lib
   • Copy the SSL keystore file directory to messaging-server/conf/ssl

7. In startmessaging.sh, correct the path for each JAR used in Java classpath to reference the jars in messaging-server/lib

8. In messaging-server/messaging correct the path for the cd command to go to {install-dir}/messaging-server

9. Copy the messaging script to its target destination:

   cp messaging-server/messaging /etc/init.d/

10. Make messaging an autostart script:

    cd /etc/init.d/

    chkconfig –add messaging
