在CentOS7上安装RabbitMQ

安装过程参考官网:

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.-.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

在CentOS7上安装RabbitMQ

这里可以看到log文件的位置,转到文件位置,打开文件:

在CentOS7上安装RabbitMQ

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=/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:

在CentOS7上安装RabbitMQ

开启管理UI:

rabbitmq-plugins enable rabbitmq_management
firewall-cmd --zone=public --add-port=/tcp --permanent
firewall-cmd --reload

在Windows下打开地址:

http://10.255.19.111:15672

在CentOS7上安装RabbitMQ

用户名和密码都是 guest

在CentOS7上安装RabbitMQ

这样就可以方便管理RabbitMQ了。
