stoppen

Der Prozess stirbt noch, aber nicht anmutig. Irgendwelche Vorschläge?

Ich habe eine Lösung gefunden, aber ich bin mir nicht sicher, ob es das Grundproblem anspricht. Sobald ActiveMQ begonnen hat überprüfte ich, um zu sehen, ob der Port 1099 tatsächlich offen ist, den folgenden Befehl:

$> netstat -lptun | grep 1099

Dieser Befehl druckt nichts zeigt, dass der Port nicht geöffnet ist (mit ActiveMQ gestartet). Dies bedeutet, dass, obwohl ActiveMQ gestartet wurde, es nicht auf JMX-Verbindungen wartet (auf diese Weise wird das Skript versuchen, es zu stoppen). Nachdem ich mich umgesehen habe, fand ich diese link, die mich zu der Datei {ACTIVEMQ_HOME} /conf/activemq.xml führte. In dieser Datei gibt es den folgenden Abschnitt:

<!-- 
    The managementContext is used to configure how ActiveMQ is exposed in 
    JMX. By default, ActiveMQ uses the MBean server that is started by 
    the JVM. For more information, see: 

     http://activemq.apache.org/jmx.html 
--> 
<managementContext> 
    <managementContext createConnector="false"/> 
</managementContext>

Einstellung createConnector = „true“ aufgelöst meine Probleme (dies wird die MBeanServer innerhalb der JVM starten, wenn ActiveMQ startet). Die Abschaltung Ausgang sieht nun wie folgt (wie erwartet):

... 
ACTIVEMQ_HOME: /opt/apache/apache-activemq-5.4.2 
ACTIVEMQ_BASE: /opt/apache/apache-activemq-5.4.2 
Connecting to JMX URL: service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi 
Stopping broker: localhost 
.. FINISHED

Zusätzlich nachdem diese Einflaggung ich, dass der Standard JMX-Port offen (1099) ist

nach dem Start ActiveMQ 
$> netstat -lptun | grep 1099 
tcp  0  0 :::1099      :::*      LISTEN  30033/java
überprüfen kann
