执行sudo apt-get install rabbitmq-server报错：
The following packages have unmet dependencies:
 linux-generic : Depends: linux-headers-generic (= 4.4.0.127.133) but 4.4.0.109.114 is to be installed
 rabbitmq-server : Depends: erlang-nox (>= 1:13.b.3) but it is not going to be installed or
                            esl-erlang but it is not installable
#### 执行
sudo apt-get install -f 

sudo apt-get install erlang-nox
sudo apt-get install rabbitmq-server

二、注册用户和管理：

Ubuntu上安装和使用RabbitMQ
1. 安装RabbitMQ服务软件包

输入以下命令进行安装

#apt install rabbitmq-server

 

2.安装完成后在rabbitMQ中添加用户

命令：#rabbitmqctl add_user username password

将用户设置为管理员（只有管理员才能远程登录）

命令：#rabbitmqctl set_user_tags username administrator

同时为用户设置读写等权限

命令：#rabbitmqctl set_permissions -p / username ".*" ".*" ".*"

 

3.安装RabbitMQ监控管理插件进行RabbitMQ的管理

命令：#rabbitmq-plugins enable rabbitmq_management

插件rabbitmq_management启动成功后就可以通过web页面进行RabbitMQ的监控和管理

 

4.使用rabbitmq_management插件进行监控和管理

使用firefox浏览器登录：http://localhost:15672

在登录页面使用 guest/guest用户名和密码登录RabbitMQ管理系统，在系统中可以对RabbitMQ服务进行channel,queue,用户等的管理

 

PS:Guest账号不能远程登录。

如果还不能远程访问或远程登录检查是不是5672, 15672端口没有开放！！！！！！

三、简单使用：

生产者：
# !/usr/bin/env python
import pika
credentials = pika.PlainCredentials('admin','123456')
connection = pika.BlockingConnection(pika.ConnectionParameters(
    '192.168.56.19',5672,'/',credentials))
channel = connection.channel()

# 声明queue
channel.queue_declare(queue='balance')

# n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange.
channel.basic_publish(exchange='',
                      routing_key='balance',
                      body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()



消费者：
# _*_coding:utf-8_*_
__author__ = 'Alex Li'
import pika

credentials = pika.PlainCredentials('admin','123456')
connection = pika.BlockingConnection(pika.ConnectionParameters(
    '192.168.56.19',5672,'/',credentials))
channel = connection.channel()

# You may ask why we declare the queue again ‒ we have already declared it in our previous code.
# We could avoid that if we were sure that the queue already exists. For example if send.py program
# was run before. But we're not yet sure which program to run first. In such cases it's a good
# practice to repeat declaring the queue in both programs.
channel.queue_declare(queue='balance')


def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)


channel.basic_consume(callback,
                      queue='balance',
                      no_ack=True)

print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()
