Add ActiveMQ to boot sequence

cd /etc/init.d
update-rc.d activemq defaults

Remove ActiveMq from boot sequence

update-rc.d -f activemq remove
rm /etc/init.d/activemq

Setup firewall

This is the list of ports that are used by ActiveMQ:

port 61616 = JMS queue access
port 11099 = JMX remote console (connector port)
port 8161 = HTTP manager
port 8162 = HTTPS manager
port 5672 = AMQP port

Edit your firewall script:

vim /etc/firewall/firewall-start.sh

#### INPUT
# messages
$IPTABLES -A INPUT -p tcp -m state --state NEW --dport 5672 -j ACCEPT       # AMQP port
$IPTABLES -A INPUT -p tcp -m state --state NEW --dport 61616 -j ACCEPT     # JMS port

# web monitoring
#$IPTABLES -A INPUT -p tcp -m state --state NEW --dport 8161 -j ACCEPT     # HTTP web-console. Not required if you're using Apache2 proxy
#$IPTABLES -A INPUT -p tcp -m state --state NEW --dport 8162 -j ACCEPT     # HTTPs web-console. Not required if you're using Apache2 proxy

# JMX monitoring
$IPTABLES -A INPUT -p tcp -m state --state NEW --dport 1099 -j ACCEPT      # JVM default RMI port
#$IPTABLES -A INPUT -p tcp -m state --state NEW --dport 11099 -j ACCEPT    # JMX standalone port. Not required if you're using default JVM JMX connector on TCP 1616

# Output
$IPTABLES -A OUTPUT -p tcp -m state --state NEW --dport 5672 -j ACCEPT 
$IPTABLES -A OUTPUT -p tcp -m state --state NEW --dport 61616 -j ACCEPT

$IPTABLES -A OUTPUT -p tcp -m state --state NEW --dport 8161 -j ACCEPT
$IPTABLES -A OUTPUT -p tcp -m state --state NEW --dport 8162 -j ACCEPT

$IPTABLES -A OUTPUT -p tcp -m state --state NEW --dport 1099 -j ACCEPT
$IPTABLES -A OUTPUT -p tcp -m state --state NEW --dport 11099 -j ACCEPT

Logs

The application's logs are in $ACTIVEMQ/data/activemq.log

cat /opt/activemq/data/activemq.log

Advanced Configuration (all O.S)

Broker settings

Edit configuration file

Linux ~ manual

vim /opt/activemq/conf/activemq.xml

Linux ~ auto

vim /etc/activemq/instances-enabled/main/activemq.xml

Windows

$ACTIVEMQ/conf/activemq.xml

Adjust broker setting

Set broker name

<broker     xmlns="http://activemq.apache.org/schema/core"
        brokerName="myServerName"
       dataDirectory="${activemq.base}/data">

Set listener to all interfaces (0.0.0.0)

<transportConnectors>
        <transportConnector name="openwire" uri="tcp://0.0.0.0:61616"/>
</transportConnectors>

Limit queues size

<systemUsage>
 <systemUsage>
  <memoryUsage>
   <memoryUsage limit="64 mb"/>
  </memoryUsage>
  <storeUsage>
   <storeUsage limit="100 gb"/>
  </storeUsage>
  <tempUsage>
   <tempUsage limit="50 gb"/>
  </tempUsage>
 </systemUsage>
</systemUsage>

Enable HTTP web console

Edit your jetty configuration

Linux ~ Manual

vim /opt/activemq/conf/jetty.xml

Windows

$ACTIVEMQ/conf/jetty.xml

Adjust broker name and listening port

At the bottom, edit connector :

<property name="connectors">
  <list>
     <bean id="Connector" class="org.eclipse.jetty.server.nio.SelectChannelConnector">
         <property name="port" value="8161" />
         <property name="host" value="0.0.0.0" />
      </bean>
    ...
  </list>
</property>

Change root context for Web-Console

Edit "jetty.xml" [look to the previous §]

Add 2 new securityConstraintMapping (line 40), " /activemq/*,/activemq-api/*, "

<bean id="securityConstraintMapping" class="org.eclipse.jetty.security.ConstraintMapping">
      <property name="constraint" ref="securityConstraint" />
      <property name="pathSpec" value="/api/*,/activemq/*,/admin/*,*.jsp" />
 </bean>

Change:

WebAppContext.contextpath value to " /activemq " instead of " /admin "
WebAppContext.contextpath value to " /activemq-api " instead of " /api "

  <property name="handler">
     <bean id="sec" class="org.eclipse.jetty.server.handler.HandlerCollection">
         <property name="handlers">
             <list>
                 <bean class="org.eclipse.jetty.webapp.WebAppContext">
                    <!-- property name="contextPath" value="/admin" / -->
                    <property name="contextPath" value="/activemq" />
                    <property name="resourceBase" value="${activemq.home}/webapps/admin" />
                    <property name="logUrlOnStart" value="true" />
                 </bean>
                 ...
                 <bean class="org.eclipse.jetty.webapp.WebAppContext">
                     <property name="contextPath" value="/activemq-api" />
                     <property name="resourceBase" value="${activemq.home}/webapps/api" />
                     <property name="logUrlOnStart" value="true" />
                 </bean>
                 ...

Manage web-users

vim /opt/activemq/conf/jetty-realm.properties

Edit last line

     admin: admin, admin

Apache 2 Virtual host and mod_proxy

Instead of using the port 8161, you can use Apache 2 mod_proxy.

!!CAREFUL!! You must let the HTTP access to the REST API.

Apache2 Virtual Host configuration:

<VirtualHost *:80>
	ServerAdmin guillaume.diaz@vehco.com
	ServerName preprodrtd.vehco.com

	## Proxy
	ProxyVia On
        ProxyPreserveHost On
        <Proxy *>
             AddDefaultCharset off
             Order deny,allow
             Allow from all
	</Proxy>

	# Active MQ REST web-service, required for hawt.io management
	ProxyPass /activemq-api http://localhost:8161/activemq-api
	ProxyPassReverse /activemq-api http://localhost:8161/activemq-api 	

	# Redirect everything else to HTTPS
	Redirect permanent / https://preprodrtd.vehco.com/
</VirtualHost>

<VirtualHost *:443>
        ...        
	## Proxy
	ProxyVia On
        ProxyPreserveHost On
        <Proxy *>
             AddDefaultCharset off
             Order deny,allow
             Allow from all
             Satisfy Any
        </Proxy>


        # ActiveMq HTTP web-console
	ProxyPass /activemq http://localhost:8161/activemq
	ProxyPassReverse /activemq http://localhost:8161/activemq 	

        # ActiveMq REST web-services, required for hawt.io
	ProxyPass /activemq-api http://localhost:8161/activemq-api
	ProxyPassReverse /activemq-api http://localhost:8161/activemq-api
</VirtualHost>

Remote management using HAWT.IO

Hawt.io is a wonderful management tool. You can use it to manage a lot of JAVA services, including ActiveMQ ; JMX ; etc.

Official website: http://hawt.io/

Download URL: http://hawt.io/getstarted/index.html > You should download the hwatio.jar file

To execute the program, just run:

java -jar hawtio-app-1.3.1.jar --port 8090

Don't hesitate to adjust the port number to your own needs! Default is 8080, which might already been used by Tomcat or Glassfish.

Go to http://localhost:8090/hawtio

Then, configure the following remote connection:

Enjoy ActiveMQ !

Enable JMX remote management and monitoring

Official documentation: http://activemq.apache.org/jmx.html

Add JMX support

Edit configuration:

vim /opt/activemq/conf/activemq.xml

Adjust the broker tag (line 35), add useJmx="true"

<broker xmlns="http://activemq.apache.org/schema/core" useJmx="true" brokerName="preprodrtd.vehco.com" dataDirectory="${activemq.data}">
...
</broker>

Make sure that you're using a new JVM connector (line 65):

<broker xmlns="http://activemq.apache.org/schema/core" useJmx="true" brokerName="preprodrtd.vehco.com" dataDirectory="${activemq.data}"> 
  ... 
  <managementContext>
     <managementContext createConnector="true" />
  </managementContext>
   ...
 </broker>

Create JMX users

User creation

vim /opt/activemq/conf/jmx.access

Add some users. As a reminder:

userMq readonly
adminMq readwrite

User password

vim /opt/activemq/conf/jmx.password

Set passwords. Usernames must match!

userMq abc123
adminMq abcd1234

JMX settings

Edit activemq launcher

vim /opt/activemq/bin/activemq

Search for ACTIVEMQ_JMX and adjust the lines to:

# ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=11099 "
ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.rmi.port=1099 "
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.access.file=${ACTIVEMQ_CONF}/jmx.access"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote"

!! Note that the default JVM RMI port will be used [TCP 1099] instead of the standalone one. !!

No you can access the console remotely using Jconsole or any other client.

URL: service:jmx:rmi:///jndi/rmi://<your hostname>:1099/jmxrmi

JMX client

Jconsole

You can use JConsole (included in Java JDK) to access the server.

ActiveMQ Browser (windows)

Download the latest version of the application: http://sourceforge.net/projects/activemqbrowser/

Unzip the file and put it in " /opt/activemq-browser "

just run the .bat file

Automatic installation

!! Depending on your distro, you might not have the web console !! This is NOT recommended.

Get binary

apt-get install activemq

Enable instance

Check instance

cd /etc/activemq/instances-enabled/
ls

... By default you should have an instance enable.

If not:

ln -s /etc/activemq/instances-available/main /etc/activemq/instances-enabled/main
cp /usr/share/activemq/activemq-options /etc/activemq/instances-available/main/options

Edit settings

vim /etc/activemq/instances-available/main/options

Adjust $INSTANCE (use 'main')

ACTIVEMQ_BASE="/var/lib/activemq/main"

Create directories

mkdir -p /var/lib/activemq/main/data
mkdir -p /var/lib/activemq/main/data/kahadb                
chown -R activemq:activemq /var/lib/activemq/main
chmod -R 755 /var/lib/activemq/main

Kahadb == MQ embedded DB
