"node with name "rabbit" already running", but also "unable to connect to node 'rabbit'"

Question

Rabbitmq server does not start, saying it's already running:

$: rabbitmq-server Activating RabbitMQ plugins ... 0 plugins activated:  node with name "rabbit" already running on "android-d1af002161676bee" diagnostics: - nodes and their ports on android-d1af002161676bee: [{rabbit,52176},                                                       {rabbitmqprelaunch2254,                                                        59205}] - current node: 'rabbitmqprelaunch2254@android-d1af002161676bee' - current node home dir: /Users/Jordan - current node cookie hash: ZSx3slRJURGK/nHXDTBRqQ== 

But, rabbitmqctl seems to think otherwise:

rabbitmqctl -n rabbit status Status of node 'rabbit@android-d1af002161676bee' ... Error: unable to connect to node 'rabbit@android-d1af002161676bee': nodedown diagnostics: - nodes and their ports on android-d1af002161676bee: [{rabbit,52176},                                                       {rabbitmqctl2462,59256}] - current node: 'rabbitmqctl2462@android-d1af002161676bee' - current node home dir: /Users/Jordan - current node cookie hash: ZSx3slRJURGK/nHXDTBRqQ== 

Any takers?

Answer 1

The rabbitmq server was running somewhere but it just couldn't be connected to.

One of the following will mention something about rabbits:

$: ps aux | grep epmd $: ps aux | grep erl 

Kill the process with kill -9 {pid of rabbitmq process}

Answer 2

i was having the same problem then I realized I was not issuing the right command.

./rabbitmqctl stop  

this works everytime, although it does take down erlang runtime too. also mind where your config file.
