Installing on RPM-based Linux (RHEL, CentOS, Fedora, openSUSE)
首先需要安装erlang，参考：http://fedoraproject.org/wiki/EPEL/FAQ#howtouse
rpm -Uvh http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm yum install erlang
安装过程中会有提示，一路输入“y”即可。
完成后安装RabbitMQ：
先下载rpm：
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.6/rabbitmq-server-3.6.6-1.el7.noarch.rpm
下载完成后安装：
yum install rabbitmq-server-3.6.6-1.el7.noarch.rpm
完成后启动服务：
service rabbitmq-server start
可以查看服务状态：
service rabbitmq-server status
这里可以看到log文件的位置，转到文件位置，打开文件：
这里显示的是没有找到配置文件，我们可以自己创建这个文件
cd /etc/rabbitmq/ vi rabbitmq.config
编辑内容如下：
[{rabbit, [{loopback_users, []}]}].
这里的意思是开放使用，rabbitmq默认创建的用户guest，密码也是guest，这个用户默认只能是本机访问，localhost或者127.0.0.1，从外部访问需要添加上面的配置。
保存配置后重启服务：
service rabbitmq-server stop service rabbitmq-server start
此时就可以从外部访问了，但此时再看log文件，发现内容还是原来的，还是显示没有找到配置文件，可以手动删除这个文件再重启服务，不过这不影响使用
rm rabbit\@mythsky.log service rabbitmq-server stop service rabbitmq-server start
开放5672端口：
firewall-cmd --zone=public --add-port=5672/tcp --permanent firewall-cmd --reload
在Windows上进行测试：
新建.net core控制台项目，引用RabbitMQ.Client包：
Install-Package RabbitMQ.Client
测试代码：
public static void Main(string[] args)
{
ConnectionFactory factory = new ConnectionFactory();
factory.UserName = "guest";
factory.Password = "guest";
factory.VirtualHost = "/";
factory.HostName = "localhost";
//factory.HostName = "10.255.19.111";
try
{
IConnection conn = factory.CreateConnection();
IModel model = conn.CreateModel();
string exchangeName = "test";
string queueName = "testq";
string routingKey = "first";
model.ExchangeDeclare(exchangeName, ExchangeType.Direct);
model.QueueDeclare(queueName, false, false, false, null);
model.QueueBind(queueName, exchangeName, routingKey, null);
byte[] messageBodyBytes = System.Text.Encoding.UTF8.GetBytes("Hello, world!");
model.BasicPublish(exchangeName, routingKey, null, messageBodyBytes);
Console.WriteLine("message sended.");
bool noAck = false;
BasicGetResult result = model.BasicGet(queueName, noAck);
if (result == null)
{
Console.Write("no message.");
}
else
{
IBasicProperties props = result.BasicProperties;
byte[] body = result.Body;
model.BasicAck(result.DeliveryTag, false);
string message = System.Text.Encoding.UTF8.GetString(body);
Console.Write(message);
}
}
catch (Exception ex)
{
Console.Write(ex.Message);
}
}
也可以使用官网的例子（这里更清晰）：
http://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html
发送端：
using System;
using RabbitMQ.Client;
using System.Text;
class Send
{
public static void Main()
{
var factory = new ConnectionFactory() { HostName = "localhost" };
using(var connection = factory.CreateConnection())
using(var channel = connection.CreateModel())
{
channel.QueueDeclare(queue: "hello",
durable: false,
exclusive: false,
autoDelete: false,
arguments: null);
string message = "Hello World!";
var body = Encoding.UTF8.GetBytes(message);
channel.BasicPublish(exchange: "",
routingKey: "hello",
basicProperties: null,
body: body);
Console.WriteLine(" [x] Sent {0}", message);
}
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
}
}
接收端：
using RabbitMQ.Client;
using RabbitMQ.Client.Events;
using System;
using System.Text;
class Receive
{
public static void Main()
{
var factory = new ConnectionFactory() { HostName = "localhost" };
using(var connection = factory.CreateConnection())
using(var channel = connection.CreateModel())
{
channel.QueueDeclare(queue: "hello",
durable: false,
exclusive: false,
autoDelete: false,
arguments: null);
var consumer = new EventingBasicConsumer(channel);
consumer.Received += (model, ea) =>
{
var body = ea.Body;
var message = Encoding.UTF8.GetString(body);
Console.WriteLine(" [x] Received {0}", message);
};
channel.BasicConsume(queue: "hello",
noAck: true,
consumer: consumer);
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
}
}
}
在Windows上发送，在CentOS上接收，效果如图：
开启管理UI：
rabbitmq-plugins enable rabbitmq_management firewall-cmd --zone=public --add-port=15672/tcp --permanent firewall-cmd --reload
在Windows下打开地址：
http://10.255.19.111:15672
用户名和密码都是 guest
这样就可以方便管理RabbitMQ了。
