Please, I need your kind help.
I am struggling since last week trying to configure RabbitMQ cluster on windows servers. I reinstalled RabbitMQ 3.7.8 and ErlangOTP 21-1 for more than 15 times trying to figure out the issue and fix it, but unfortunately, all of my attempts failed.
My environment: Three virtual machines with OS: windows server 2012
Environment Variable setting:
• ERLANG_HOME = C:\Program Files\erl10.1
• path: C:\Program Files\Handle
• %RABBITMQ_BASE% = c:\RabbitMQ
• %RABBITMQ_CONFIG_FILE% = %RABBITMQ_BASE%
• RABBITMQ_NODENAME = masternode
• Server names: RabbitMQ01 “masternode” , RabbitMQ02, RabbitMQ03
• Adding IP & hots name “masternode” in the host file for name resolution (C:\Windows\System32\drivers\etc\hosts)
• Setting RabbitMQ configuration file “advanced.config” in c:\users\USERNAME\AppData\Roaming\RabbitMQ” to enable users to login to RabbitMQ management remotely by adding the following setting
[
{rabbit,
[
{tcp_listeners, [5672]},
{loopback_users, []},
{num_tcp_acceptors, 100}
]
}
].
Installing steps: (for each server)
1. After setting the environment variables, I restarted the machine. Then
2. Install ErlangOTP 21-1
3. Install RabbitMQ 3.7.8 server
4. Enable plugins - rabbitmq-plugins.bat enable rabbitmq_management
After completing the installation of the above servers, I start configuring the cluster
- First, I verified that masternode is reachable from RabbitMQ02, 02 by pinging Rabbit@masternode and it’s successful.
Stopped RabbitMQ server and App by using the following command
rabbitmq-service stop rabbitmqctl stop_app
- Copy .erlang.cookie from masternode “path=c:\windows\system32\config\ systemprofile” to RabbitMQ02 “path= c:\windows\system32\config\ systemprofile” and “path=c:\users\USERNAME”.
Start RabbitMQ service & App by executing the below commands
rabbitmqctl start_app rabbitmq-service start
- Stop App again by executing this command “rabbitmqctl stop_app”
- I start joining RabbitMQ02 to masternode
rabbitmqctl join_cluster rabbit@masternode(small case)
Once I reach this point, I’m getting the following error on RabbitMQ02.
C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.8\sbin>rabbitmqctl join_cluster rabbit@masternode Error: unable to perform an operation on node 'rabbit@rhrabbitmq02'. Please see diagnostics information and suggestions below.
Most common reasons for this are:
- Target node is unreachable (e.g. due to hostname resolution, TCP connection o r firewall issues)
- CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
- Target node is not running
In addition to the diagnostics info below:
- See the CLI, clustering and networking guides on http://rabbitmq.com/document ation.html to learn more
- Consult server logs on node rabbit@rhrabbitmq02
DIAGNOSTICS
attempted to contact: [rabbit@rhrabbitmq02]
rabbit@rhrabbitmq02: * connected to epmd (port 4369) on rhrabbitmq02 * epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traff ic * TCP connection succeeded but Erlang distribution failed
- Authentication failed (rejected by the remote node), please check the Erlang cookie
Current node details: * node name: rabbitmqcli41@rhrabbitmq02 * effective user's home directory: C:\Users\admin * Erlang cookie hash: pndBksvQokXyiSqBdnne/g==

masternode- it's right there in the output. Onmasternode, what is the output ofrabbitmqctl status? – Luke Bakken
