Hi,
I have been working with apache cellar for the last two days to experiment
how the clustering is done. I followed some points from
http://blog.nanthrax.net/2012/02/apache-karaf-cellar-and-central-management/
to cluster in different instances on one karaf installation. Instances are
created via 'instance:create'. This works well too.. Thanks Jean-Baptiste
Now my actual requirement is to cluster the karaf on the different
machines. I hardly know the hazelcast and its configurations.
This is the setup that I need to configure.
I have a Physical machine and two VMs , all with ubuntu 12.04 desktop
installations.
These are the Ips and host names
Physical/Vm | Host Name | IP
-----------------------------------------------
Physical | fly-dt249 | 192.168.14.123
Vm | ubuntuvm1 | 192.168.14.124
Vm | ubuntuvm1 | 192.168.14.125
I have the following hazelccast.xml net configuration, in the host
"fly-dt249" (Physical machine) Dont know how precise it is for the above
configutaion( Please help me to correct this xm if it's wrong).
<network>
<port auto-increment="true" port-count="100">5701</port>
<outbound-ports>
<!--
Allowed port range when connecting to other nodes.
0 or * means use system provided port.
-->
<ports>0</ports>
</outbound-ports>
<join>
<multicast enabled="false">
<multicast-group>224.2.2.3</multicast-group>
<multicast-port>54327</multicast-port>
</multicast>
<tcp-ip enabled="true"><!-- this is where I have doubt-->
<hostname>ubuntuvm1</hostname>
<hostname>ubuntuvm1</hostname>
<interface>127.0.1.1</interface>
<interface>192.168.14.123-127<interface>
</tcp-ip>
<aws enabled="false">
<access-key>my-access-key</access-key>
<secret-key>my-secret-key</secret-key>
<!--optional, default is us-east-1 -->
<region>us-west-1</region>
<!--optional, default is ec2.amazonaws.com. If set, region
shouldn't be set as it will override this property -->
<host-header>ec2.amazonaws.com</host-header>
<!-- optional, only instances belonging to this group will
be discovered, default will try all running instances -->
<security-group-name>hazelcast-sg</security-group-name>
<tag-key>type</tag-key>
<tag-value>hz-nodes</tag-value>
</aws>
</join>
<interfaces enabled="false">
<interface>10.10.1.*</interface>
</interfaces>
<ssl enabled="false"/>
<socket-interceptor enabled="false"/>
<symmetric-encryption enabled="false">
<!--
encryption algorithm such as
DES/ECB/PKCS5Padding,
PBEWithMD5AndDES,
AES/CBC/PKCS5Padding,
Blowfish,
DESede
-->
<algorithm>PBEWithMD5AndDES</algorithm>
<!-- salt value to use when generating the secret key -->
<salt>thesalt</salt>
<!-- pass phrase to use when generating the secret key -->
<password>thepass</password>
<!-- iteration count to use when generating the secret key -->
<iteration-count>19</iteration-count>
</symmetric-encryption>
</network>
So while I start Karaf(installed with cellar) in all the machines, and
issue the command, 'cellar:node-list' i get only the following output
| Id | Host Name | Port
-------------------------------------------------
x | fly-dt249.local:5701 | fly-dt249.local | 5701
Do I need to configure the same on the my Vm karaf's hazelcast.xml also..?
If so , somebody please help me out as I am almost struck with this.
Thanks in advance..!
Noushad.
