    [ https://issues.apache.org/jira/browse/CLOUDSTACK-5879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13873045#comment-13873045 ] 

Murali Reddy commented on CLOUDSTACK-5879:
------------------------------------------

The RabbitMQ AMQP server settings are stored as follows in the componentContext.xml file till 4.2:
<bean id="eventNotificationBus"
class="org.apache.cloudstack.mom.rabbitmq.RabbitMQEventBus">
<property name="name" value="eventNotificationBus"/>
<property name="server" value="127.0.0.1"/>
<property name="port" value="5672"/>
<property name="username" value="guest"/>
<property name="password" value="guest"/>
<property name="exchange" value="cloudstack-events"/>
</bean>

>From 4.3 due to spring modularization, spring config file need to be changed. Also till 4.2, passwords are unencrypted. From 4.3 its recommended that password is encrypted. A spring config file for RabbitMQ event bus with content below should be placed in config path.

> From 4.3 RabbitMq event bus plug-in configuration need to be specified differently (in 4.2 and 4.1 it was specified in componenetConext file) in separate file. This doc bug is to get the necessary details required for 4.3
