Name of broker - should maybe correlate with host name?
Installing ActiveMQ
  1. Download the latest stable ActiveMQ release (apache-activemq-x.y.z.tar.gz).
  2. Move to the installation root cd /usr/local.
  3. Unpack the release tar xzvf /path/to/apache-activemq-x.y.z.tar.gz
  4. Create ActiveMQ user account useradd activemq
  5. Optional: Edit the global configuration files vim /usr/local/apache-activemq-x.y.z/conf/{activemq,jetty}.xml before setting up instances.
  6. Optional: Setup service script
Configuring instances

For each broker instance:

  1. Switch to activemq account su - activemq
  2. If needed, create an instance wide setup file /usr/local/apache-activemq-x.y.z/bin/activemq setup ~activemq/.activemqrc. (ActiveMQ doesn't seem to use per instance rc files any more?)
  3. Create broker instance configuration /usr/local/apache-activemq-x.y.z/bin/activemq create $(INSTANCE_NAME)
  4. Configure broker vim $(INSTANCE_NAME)/conf/{activemq,jetty}.xml
  5. Optional: Set up key and trust stores in $(INSTANCE_NAME)/conf/broker.{k,t}s
  6. Optional: Add broker to the service script, so that the broker may be automatically started on reboot.
Service/Init Script

For now see here

Later, something like this should work:

  1. chmod +x /etc/init.d/activemq
  2. chkconfig --add activemq
  3. chkconfig activemq on
  4. /etc/init.d/activemq start
# activemq-start.sh
#!/bin/bash
echo Starting ActiveMQ....
sh /home/activemq/test-broker-1/bin/test-broker-1 start
sh /home/activemq/test-broker-2/bin/test-broker-2 start

# activemq-stop.sh
#!/bin/bash
echo Stopping ActiveMQ....
sh /home/activemq/test-broker-1/bin/test-broker-1 stop
sh /home/activemq/test-broker-2/bin/test-broker-2 stop

# activemq
#!/bin/bash
