The problem of inconsistent host names in building rabbitmq on Linux

1. Environment:

centos 7.3

2. Problem description

Today, the following error occurred in the process of deploying rabbitmq as a front-end and back-end message push

$ rabbitmqctl set_permissions -p/duni ".*" ".*" ".*"

Error: unable to connect to node rabbit@bbbbdddd: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@bbbbdddd]

rabbit@bbbbdddd:
  * connected to epmd (port 4369) on bbbbdddd
  * epmd reports node 'rabbit' running on port 25672
  * TCP connection succeeded but Erlang distribution failed

  * Hostname mismatch: node "rabbit@localhost" believes its host is different. Please ensure that hostnames resolve the same way locally and on "rabbit@localhost"


current node details:
- node name: 'rabbitmq-cli-92@bbbbdddd'
- home dir: /var/lib/rabbitmq
- cookie hash: h6TDjQ+DgPaVGJLMjcG4TA==

I can’t connect to the host where I deployed rabbitmq bbbbdddd

3. Google

Google found the corresponding problem in stack overflow

Here we say to give rabbitmq command permission, delete the service and then re install it. After trying, I found that I can’t do it…

Continue with Google, and some people say to correct Erlang’s Cookie:

Erlang will generate two cookie files: C: windows. Erlang. Cookie and C: user. Erlang. Cookie. Check whether the contents of the two files are consistent. If not, replace one with the other.

Windows platform, er… My environment is Linux, and I didn’t find two . Erlang. Cookie files in the root directory

$ find/--name .erlang.cookie
/var/lib/rabbitmq/.erlang.cookie

So I gave up.

4. Solutions

The final solution is to set the host name and restart the rabbitmq service

# Kill the rabbitmq process first
$ ps -ef | grep rabbitmq | grep -v grep | awk '{print $2}' | xargs kill -9

# set hostname (assume host ip is: 192.168.1.1, hostname set to: mq)
$ echo 192.168.1.1 mq > /etc/hosts
$ echo rabbitmq > /etc/hostname
$ export HOSTNAME=mq

# Restart rabbitmq
$ rabbitmq-server -detached
# Start the web socket service
$ rabbitmq-plugins enable rabbitmq_management rabbitmq_web_stomp
# Set up users and give them administrator privileges
$ rabbitmqctl add_user duni duni
$ rabbitmqctl set_user_tags duni administrator
# set user directory
$ rabbitmqctl set_permissions -p/duni ".*" ".*" ".*"

Ubuntu: rabbitmq reports an error; Solution error: unable to connect to node rabbit@localhost : nodedown

When installing rabbitmq and executing rabbitmqctl status, the errors are as follows:

the first thing is to check the log file and form a good habit here’s my list:

root@jin:/# cd /var/log/rabbitmq/
root@jin:/var/log/rabbitmq# ls
[email protected]  [email protected]  startup_err  startup_log
# Afterwards, execute the view
cat [email protected]

As shown in the figure:

my reason is that port 5672 is occupied by other applications, so rabbitmq can’t be used. Just modify the port

RabbitMQ The channelMax limit is reached. Try later. [How to Solve]

Anomaly interpretation

In a high concurrency scenario, the number of channels reaches the limit, so they cannot continue to be created

Self-built rabbitmq solution

1. Custom configuration

@Configuration
@Slf4j
public class RabbitMQConfig {


    @Bean
    public RabbitTemplate rabbitTemplate(final ConnectionFactory connectionFactory) {
        CachingConnectionFactory cachingConnectionFactory = (CachingConnectionFactory) connectionFactory;
        // set ChannelMax as 4095
        cachingConnectionFactory.getRabbitConnectionFactory().setRequestedChannelMax(4095);
        final RabbitTemplate rabbitTemplate = new RabbitTemplate(cachingConnectionFactory);
        rabbitTemplate.setMessageConverter(jackson2MessageConverter());
        rabbitTemplate.setMandatory(true);
        rabbitTemplate.setConfirmCallback((correlationData, b, s) -> {
            if(!b){
                log.error("confirmCallBack Sending failed data: {}",correlationData);
                log.error("confirmCallBack Confirmation status: {}",b);
                log.error("ConfirmCallBack Reason for sending failure: {}",s);
            }
        });
        rabbitTemplate.setReturnCallback((message, i, s, s1, s2) -> {
            log.error("returnCallBack message: {}",message);
            log.error("returnCallBack response code: {}",i);
            log.error("returnCallBack response message: {}",s);
            log.error("returnCallBack Switch: {}",s1);
            log.error("returnCallBack Routing Key.{}",s2);
        });
        return rabbitTemplate;
    }

    @Bean
    public Jackson2JsonMessageConverter jackson2MessageConverter() {
        return new Jackson2JsonMessageConverter();
    }
}

2. Modify the configuration of MQ server synchronously
rabbitmq.conf

## Set the max permissible number of channels per connection.
## 0 means "no limit".
##In the configuration file, just enter the following parameters and the value you want to set, if you don't use 2047, then you don't need to configure
# channel_max = 128

Rabbitmq solution for cloud services

For paid versions of MQ cloud services, you can try the following to configure rabbitMq connection caching

springBoot 2.3+

  rabbitmq:
    cache:
      connection:
        size: 1000
      channel:
        size: 64

Yesterday afternoon Docker started RabbitMQ and reported an error. I checked a lot of information and could not get it right. Finally, Docker was restarted and solved.
in addition to pull the rabbitmq is take the web management interface with management, command to write

docker pull rabbitmq:management

At the beginning of the pull is wrong for a long time

[root@localhost etc]# docker images

solution

miaosha.queue queue could not be found, an inspection found that the queue was not configured in the @configuration file,

add the relevant queue to the configuration class to 

@Configuration
public class MQConfig {

    public static final String MIAOSHA_QUEUE = "miaosha.queue";

    @Bean
    public Queue miaoShaQueue(){
        return new Queue(MIAOSHA_QUEUE,true);
    }
}
