Hi All,
I am trying to setup a master-slave with nfs4 shared file system. The
problem i am facing is that broker service (from master and slave server
separately) is not coming up with with all things correct. Please see
below what i am try to do:
SETUP:
Amazon Ec2
3 servers total:
[1- master ec2 instance
1- slave ec2 instance
1- nfs4 server with shared directory exported to master and slave]
ActiveMQ version - 5.8
What i have done till now:
1) Install ActiveMQ 5.8 on master and slave ec2 instances.
2) Setup a nfs4 server with shared path (/path/mounted/shared-file-system/)
2) Mounted shared path from Nfs4 server to both master and slave. Thus both
master and slave has shared path now.
3) Created a new broker in the shared path from master
COMMAND - $(ActivemqHome)/bin/activemq-admin create broker-shared
/path/mounted/shared-file-system/
4) Updated the path in
/path/mounted/shared-file-system/broker-shared/conf/activemq.xml -
broker ... >
...
<persistenceAdapter>
<kahaDB directory="/path/mounted/shared-file-system/"/>
</persistenceAdapter>
...
</broker>
5) Now trying to start the broker service one by one from master and slave
instance:
command-
Master server -
cd /path/mounted/shared-file-system/
/broker-shared/bin/broker-shared console
Slave server -
cd /path/mounted/shared-file-system/
/broker-shared/bin/broker-shared console
ISSUE:
Service is not coming up fully, like all required ports are not starting
(The transport openwire, amqp and jetty) and as a result there can be no
connection from Client (or to Activemq admin page). Here are the startup
logs from both master and slave servers separately:

What i understood from master-slave with sharedfile system setup is that
both master and slave server will have shared path where the broker
configuration will reside. And both will start the broker service separately
on their instances but master will listen and slave will wait. Client will
connect to failover:// protocl (which is understood).
Please tell me where i am wrong in my attempt.
Thanks
