[Fixed]-I cannot start rabbitmq on my mac

Here are a few commands to get you started. Just open your cli and type from anywhere

brew services start rabbitmq     //start 
brew services stop  rabbitmq     //stop

brew services restart rabbitmq   //restart 

You can also list all the running services by

brew services list

Alternative way –

Go to the directory where rabbitMQ is installed and run following commands

cd rabbitmq_server-3.5.3/      //check you's version 
sbin/rabbitmq-server           //start server 

sbin/rabbitmqctl shutdown      //stop server 

UPDATED

USL: http://localhost:15672/

Login try this

username: guest
password: guest

Try with brew services start rabbitmq in terminal after that go to

localhost:15672 enter username and password which is

username-guest 
password-guest
