How to set the default activemq 5.10.0 configuration file?

Hello,

In hope to configure correctly my apache activemq my Ubuntu I followed the tutorials from

http://servicebus.blogspot.com/2011/02/installing-apache-active-mq-on-ubuntu.html

Everything worked just fine I started the broker and stopped it. Now I tried to start it back with 

sudo /etc/init.d/activemq start

I then have this output

INFO: Loading '/etc/default/activemq'
INFO: Using java '/usr/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties       to get details
INFO: changing to user 'leo' to invoke java
INFO: pidfile created : '/opt/activemq/data/activemq-leo-Aspire-5742G.pid' (pid '22579')

Running 

sudo /etc/init.d/activemq status

I get 

INFO: Loading '/etc/default/activemq'
INFO: Using java '/usr/bin/java'
ActiveMQ not running

What I truly find odd is that when I move to 

/opt/apache-activemq-5.10.0

and issue the command 

./activemq start

It returns

ERROR: There are syntax errors in '/etc/default/activemq'

So I deleted the /etc/default/activemq file and ran ./activemq start once again and here it runs once again.

    INFO: Using default configuration
(you can configure options in one of these file: /etc/default/activemq     /home/leo/.activemqrc)

INFO: Invoke the following command to create a configuration file
./activemq setup [ /etc/default/activemq | /home/leo/.activemqrc ]

INFO: Using java '/usr/bin/java'
INFO: Process with pid '22810' is already running

Below is my present erroneous configuration file. How should I configure the configuration file?

Actually it is because in the /activmq script under Using instances there are someif else statements, if the file is not found it redirects to a default file, open the script and look

see here for more info

Unix configuration

happy coding !

For your script, its possible your issue is here:

-    Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"

Use have spaces between your - and Dcom. These are JVM arguments and should not have a space between the - and D:

-Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"

That may have been a copy and paste format issue, but the error you presented doesn't give much to look at. Make sure the other arguments after that also have no spaces between the flag and the D.

As far as the process already running is concerned, it looks like you had started ActiveMQ already.

You can use the following command to determine if its running if the script is not working for you:

ps -ef | grep activemq

I would recommend following documentation on http://activemq.apache.org/ rather than the link you followed if you are just learning ActiveMQ. There is much more to configure and understand beyond what was mentioned in that post. It makes things a bit more complicated than they need to be if you are just learning.
