[rabbitmq-discuss] RabbitMQ Clustering

Mon May 17 10:30:19 BST 2010

Hi, 

Am trying to cluster two rabbitmq servers running on two independent
nodes, 

Node 1 terminal

--------------------

[root at morungole sbin]# rabbitmqctl status

./..

Status of node rabbit at morungole ...

[{running_applications,[{rabbit,"RabbitMQ","1.7.2"},

                        {mnesia,"MNESIA  CXC 138 12","4.4.7"},

                        {os_mon,"CPO  CXC 138 46","2.1.8"},

                        {sasl,"SASL  CXC 138 11","2.1.5.4"},

                        {stdlib,"ERTS  CXC 138 10","1.15.5"},

                        {kernel,"ERTS  CXC 138 10","2.12.5"}]},

 {nodes,[rabbit at morungole]},

 {running_nodes,[rabbit at morungole]}]

...done.

Node 2  terminal 

--------------------------

[root at mocovir2 sbin]# rabbitmqctl -n MocovirRabbit at mocovir2 status

Status of node 'MocovirRabbit at mocovir2' ...

[{running_applications,[{rabbit,"RabbitMQ","1.7.2"},

                        {mnesia,"MNESIA  CXC 138 12","4.4.12"},

                        {os_mon,"CPO  CXC 138 46","2.2.4"},

                        {sasl,"SASL  CXC 138 11","2.1.8"},

                        {stdlib,"ERTS  CXC 138 10","1.16.4"},

                        {kernel,"ERTS  CXC 138 10","2.13.4"}]},

 {nodes,['MocovirRabbit at mocovir2']},

 {running_nodes,['MocovirRabbit at mocovir2']}]

...done.

[root at mocovir2 sbin]# rabbitmqctl -n MocovirRabbit at mocovir2 stop_app
Stopping node 'MocovirRabbit at mocovir2' ...

...done.

[root at mocovir2 sbin]# rabbitmqctl -n MocovirRabbit at mocovir2 reset
Resetting node 'MocovirRabbit at mocovir2' ...

...done.

[root at mocovir2 sbin]# rabbitmqctl -n MocovirRabbit at mocovir2 cluster
rabbit at morungole

Clustering node 'MocovirRabbit at mocovir2' with [rabbit at morungole] ...

...done.

[root at mocovir2 sbin]# rabbitmqctl -n MocovirRabbit at mocovir2 start_app

Starting node 'MocovirRabbit at mocovir2' ...

...done.

[root at mocovir2 sbin]# rabbitmqctl -n MocovirRabbit at mocovir2 status

Status of node 'MocovirRabbit at mocovir2' ...

[{running_applications,[{rabbit,"RabbitMQ","1.7.2"},

                        {mnesia,"MNESIA  CXC 138 12","4.4.12"},

                        {os_mon,"CPO  CXC 138 46","2.2.4"},

                        {sasl,"SASL  CXC 138 11","2.1.8"},

                        {stdlib,"ERTS  CXC 138 10","1.16.4"},

                        {kernel,"ERTS  CXC 138 10","2.13.4"}]},

 {nodes,['MocovirRabbit at mocovir2']},

 {running_nodes,['MocovirRabbit at mocovir2']}]

...done.

Even though it is telling Clustering is done. Both the rabbitmq nodes
are not able to recognize each other.  

Can you please tell me where am going wrong ?\

The .erlang.cookie  in $HOME was not same at the beginning . Then i
copied the .erlang.cookie content from Node 1 (rabbit at morungole) to Node
2 ( MocovirRabbit at mocovir2 )
