RabbitMQ TLS tls_connection:format_status / 2崩溃

I'm trying to make a simple TLS connection using Go, and RabbitMQ reports this issue upon attempting to create a connection with TLS enabled (Go client):

This is my Go client:

package main

import (
  "fmt"
  "log"
  "crypto/tls"
  "crypto/x509"
  "io/ioutil"

  "github.com/streadway/amqp"
)

func failOnError(err error, msg string) {
  if err != nil {
    log.Fatalf("%s: %s", msg, err)
    panic(fmt.Sprintf("%s: %s", msg, err))
  }
}
func main() {

cfg := new(tls.Config)
cfg.RootCAs = x509.NewCertPool()

if ca, err := ioutil.ReadFile("/certificates/ca_certificate.pem"); err == nil {
  cfg.RootCAs.AppendCertsFromPEM(ca)
}

if cert, err := tls.LoadX509KeyPair("/certificates/client_certificate.pem", "/certificates/client_key.pem"); err == nil {
  cfg.Certificates = append(cfg.Certificates, cert)
}

conn, err := amqp.DialTLS("amqps://guest:guest@rabbitmq:5671", cfg)

failOnError(err, "Failed to connect to RabbitMQ")
defer conn.Close()

ch, err := conn.Channel()
failOnError(err, "Failed to open a channel")
defer ch.Close()

q, err := ch.QueueDeclare(
  "hello", // name
  false, // durable
  false, // delete when unused
  false, // exclusive
  false, // no-wait
  nil, // arguments
)
failOnError(err, "Failed to declare a queue")

msgs, err := ch.Consume(
 q.Name, // queue
 "", // consumer
 true, // auto-ack
 false, // exclusive
 false, // no-local
 false, // no-wait
 nil, // args
)
failOnError(err, "Failed to register a consumer")

forever := make(chan bool)

go func() {
  for d := range msgs {
    log.Printf("Received a message: %s", d.Body)
  }
}()

log.Printf(" [*] Waiting for messages. To exit press CTRL+C")
<-forever
}

And this is my RabbitMQ config file:

loopback_users.guest = false
listeners.tcp.default = 5672
hipe_compile = false
management.listener.port = 15672
management.listener.ssl = false

listeners.ssl.1 = 5671
ssl_options.cacertfile = /certificates/ca_certificate.pem
ssl_options.certfile = /certificates/server_certificate.pem
ssl_options.keyfile = /certificates/server_key.pem

I don't know Erlang nor do I have experience with RabbitMQ itself or even TLS for that matter, and this forum post was the closest I got for this issue:

https://bugs.erlang.org/browse/ERL-539

Any ideas of what could cause this?

Some additional details:

  • Erlang version: 20
  • Erlang SSL version: 20.2
  • RabbitMQ version: 3.7.4
  • Running within docker-compose using RabbitMQ's official image
  • I've generated the certificates using the tls-gen tool as suggested by the official documentation.

此行:</ p>

 “ / certificates / server_key.pem”,{错误 ,eacces} 
</ code> </ pre>

这意味着RabbitMQ没有读取文件的权限,因此运行:</ p>

  chmod  0644 /certificates/server_key.pem
</ pre>

解决了该问题。</ p>

原文

This line:

"/certificates/server_key.pem",{error,eacces}

It meant that RabbitMQ had no permission to read the file, so running:

chmod 0644 /certificates/server_key.pem

Solved the issue.
