강의를 따라하며 circuitbreaker custom config 파일을 만들었는데요. 빈에 주입하게 되실겁니다. 하고 코드에서 별다른 수정이 없는데 적용이 된건가요?빈에 따로 주입하지않아도 만들기만하면 알아서 적용이 되는건가요???

안녕하세요! config-service에 rabbitmq 설정 정보를 추가하고 실행시켜 보니 다음과 같은 에러가 뜨며 Rabbit health check failed라고 나오는데 몇시간 동안 찾아봐도 해결이 안되서 질문 드립니다ㅠㅠ       Caused by: java.io.IOException: null at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:129) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.impl.AMQChannel.wrap(AMQChannel.java:125) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.impl.AMQChannel.exnWrappingRpc(AMQChannel.java:147) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:439) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:1225) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:1173) ~[amqp-client-5.13.1.jar:5.13.1] at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.connectAddresses(AbstractConnectionFactory.java:640) ~[spring-rabbit-2.4.2.jar:2.4.2] at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.connect(AbstractConnectionFactory.java:615) ~[spring-rabbit-2.4.2.jar:2.4.2] at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:565) ~[spring-rabbit-2.4.2.jar:2.4.2] ... 49 common frames omitted Caused by: com.rabbitmq.client.ShutdownSignalException: connection error; protocol method: #method<connection.close>(reply-code=541, reply-text=INTERNAL_ERROR - access to vhost '/' refused for user 'jjh': vhost '/' is down, class-id=10, method-id=40) at com.rabbitmq.utility.ValueOrException.getValue(ValueOrException.java:66) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.utility.BlockingValueOrException.uninterruptibleGetValue(BlockingValueOrException.java:36) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.impl.AMQChannel$BlockingRpcContinuation.getReply(AMQChannel.java:502) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.impl.AMQChannel.privateRpc(AMQChannel.java:293) ~[amqp-client-5.13.1.jar:5.13.1] at com.rabbitmq.client.impl.AMQChannel.exnWrappingRpc(AMQChannel.java:141) ~[amqp-client-5.13.1.jar:5.13.1]   ... 55 common frames omitted       계정 문제인것 같아서, 새로 유저 추가 및 권한 설정 하고 vhost도 추가해줬는데도 같은 에러가 나옵니다. 웹페이지에서 보면 stopped 되었다고 나오는데 이부분이 문제인 걸까요??   또한, sudo rabbitmqctl reset, stop_app 등 명령어를 실행하면 다음과 같은 에러가 나오는데 이유를 모르겠습니다     Error: unable to perform an operation on node 'rabbit@localhost'. 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 or 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 https://rabbitmq.com/documentation.html to learn more  * Consult server logs on node rabbit@localhost  * If target node is configured to use long node names, don't forget to use --longnames with CLI tools   DIAGNOSTICS ===========   attempted to contact: [rabbit@localhost]   rabbit@localhost:   * connected to epmd (port 4369) on localhost   * epmd reports: node 'rabbit' not running at all                   no other nodes on localhost   * suggestion: start the node   Current node details:      

microservice 분산추적 강의를 전부 봤지만rabbitmq가 어떤용도로 사용되었는지 잘 모르겠습니다. CircuitBreaker 와 Slueth, Zipkin 을 구현하는데 rabbitmq 가 필요하나요? 전체 강의를 다 본다음 다시한번 봐야겠네요.
