Is rabbitmq needed on worker server?

Question

RabbitMQ

There are 2 servers:
1) jobs appear
2) php executes these jobs
On 1 machine they are queued, on 2 it connects to 1 and takes the job, right?
Rabbitmq-server needs to be installed on both machines?
If so, how do you set them up then?

Answer 1

The server is generally stored on a separate isolated machine to which there is access from others. Sometimes they put on the same, but this is more likely from a lack of resources or poverty of experience

Answer 2

RabbitMQ needs to be installed on one machine, and the client usually takes over tasks on another.
What is there to set up? The documentation is good to read.
