ActiveMQ CentOS 7

[Opencast-Newbie]

I'm trying to make ActiveMQ start with the system. I tried this command-line.

systemctl start activemq.service

When i restart the computer, activemq doesn't run.


Any Idea why?

Thanks

Hi I have the same problem here, activemq as service "starts" but not working.

If you use "/bin/activemq start" works

Why activemq as a service doesn't works?

You'll need to "enable" the service in addition to starting it (it doesn't matter which order you enable/start a service):

bash# systemctl enable activemq

This is basically the systemd version of 'chkconfig', which would control the init.d files. The other sub-command that you might want to know is 'status':

bash# systemctl status activemq
activemq.service
   Loaded: loaded (/etc/rc.d/init.d/activemq)
   Active: active (exited) since Mon 2015-11-09 18:26:56 PST; 1 weeks 6 days ago
  Process: 2186 ExecStart=/etc/rc.d/init.d/activemq start (code=exited, status=0/SUCCESS)

That should show you the service is both loaded and active. At that point, it should survive a reboot. =)

Okay. I kinda solved the problem.

My problem was that i starte activemq for the first time as a root. The service starts as user: activemq. Well my the activemq user can't acess the log files and other files, because its not root. So i changed the file owner from root to activemq, and then it worked.


With:
systemctl status activemq ... Its showes its active and running

But with

activemq status

it says its not running.

It seems to be running.. but i have to investigate more.

I have dont that, and fixed some other problems.

"systemctl enable activemq " tells me its running, but "activemq status" says its not.

Any idea why?

Do you have an ActiveMQ process actually running?

bash$ ps -ef | grep activemq
activemq  2260     1  0 Nov09 ?        00:38:26 java -Xms1G -Xmx1G -Djava.util.logging.config.file=logging.properties -Djava.security.auth.login.config=/srv/activemq/conf/login.config -Dcom.sun.management.jmxremote -Djava.awt.headless=true -Djava.io.tmpdir=/srv/activemq/tmp -Dactivemq.classpath=/srv/activemq/conf: -Dactivemq.home=/srv/activemq -Dactivemq.base=/srv/activemq -Dactivemq.conf=/srv/activemq/conf -Dactivemq.data=/srv/activemq/data -jar /srv/activemq/bin/activemq.jar start

If so, try going to the admin page for ActiveMQ via your web browser (you may need to open some firewall rules):

http://your-activemq-host:8161 or

http://localhost:8161

If it's not running, make sure you copied the activemq.xml file to the right place, as mentioned in the docs: http://docs.opencast.org/latest/admin/configuration/message-broker/

Give that a shot and see what happens. =)
