篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了RabbitMQ安装以及集群部署相关的知识,希望对你有一定的参考价值。

本次记录安装RabbitMQ的过程,只针对MAC下单机版安装、单机集群安装方法以及配置haproxy负载均衡。

 

  • RabbitMQ单机版本安装
消息发送原理:
应用程序和Rabbit Server之间会创建一个TCP连接,一旦TCP打开,并通过了认证,认证就是你试图连接Rabbit之前发送的Rabbit服务器连接信息和用户名和密码,有点像程序连接数据库,使用Java有两种连接认证的方式,后面代码会详细介绍,一旦认证通过你的应用程序和Rabbit就创建了一条AMQP信道(Channel)。
信道是创建在“真实”TCP上的虚拟连接,AMQP命令都是通过信道发送出去的,每个信道都会有一个唯一的ID,不论是发布消息,订阅队列或者介绍消息都是通过信道完成的。

为什么不通过TCP直接发送命令?
对于操作系统来说创建和销毁TCP会话是非常昂贵的开销,假设高峰期每秒有成千上万条连接,每个连接都要创建一条TCP会话,这就造成了TCP连接的巨大浪费,而且操作系统每秒能创建的TCP也是有限的,因此很快就会遇到系统瓶颈。
如果我们每个请求都使用一条TCP连接,既满足了性能的需要,又能确保每个连接的私密性,这就是引入信道概念的原因。

RabbitMQ基础概念:
ConnectionFactory(连接管理器)、Channel(信道)、Exchange(交换器)、Queue(队列)、RoutingKey(路由键)、BindingKey(绑定键)。
  • ConnectionFactory(连接管理器):应用程序与Rabbit之间建立连接的管理器,程序代码中使用;
  • Channel(信道):消息推送使用的通道;
  • Exchange(交换器):用于接受、分配消息;
  • Queue(队列):用于存储生产者的消息;
  • RoutingKey(路由键):用于把生成者的数据分配到交换器上;
  • BindingKey(绑定键):用于把交换器的消息绑定到队列上;

 MAC下配置 brew  命令行: brew install rabbitmq 会帮助安装依赖的各个环境, 如Erlang等, 方便安装和卸载。

基础命令:

启动 : ./rabbitmq-server -detached (后台启动)

查看状态:./rabbitmqctl status

查看web管理界面:http://localhost:15672/#/

停止:./rabbitmqctl stop

  • RabbitMQ单机集群安装(适合开发练习)

由于在一个机器启动多个服务,会存在端口冲突问题,启动的时候需要设置不同的端口和节点名称。这里启动三个节点(rabbit_node_one、rabbit_node_two、rabbit_node_three)组合一个集群。

1、分别启动三个节点:

rabbit_node_one: 使用默认端口

RABBITMQ_NODE_PORT=5672 RABBITMQ_NODENAME=rabbit_node_one ./rabbitmq-server -detached

 rabbit_node_two:

RABBITMQ_NODE_PORT=5673 RABBITMQ_SERVER_START_ARGS="-rabbitmq_management listener [{port,15673}] -rabbitmq_stomp tcp_listeners [61614] -rabbitmq_mqtt tcp_listeners [1884]" RABBITMQ_NODENAME=rabbit_node_two ./rabbitmq-server -detached

rabbit_node_three:
RABBITMQ_NODE_PORT=5674 RABBITMQ_SERVER_START_ARGS="-rabbitmq_management listener [{port,15674}] -rabbitmq_stomp tcp_listeners [61615] -rabbitmq_mqtt tcp_listeners [1885]" RABBITMQ_NODENAME=rabbit_node_three ./rabbitmq-server -detached

 

2、集群配置: rabbit_node_one 为主节点

配置rabbit_node_two 为持久化节点 从节点:

./rabbitmqctl -n rabbit_node_two stop_app
./rabbitmqctl -n rabbit_node_two reset
./rabbitmqctl -n rabbit_node_two join_cluster rabbit_node_one
./rabbitmqctl -n rabbit_node_two start_app

rabbit_node_three 为内存节点 从节点::
./rabbitmqctl -n rabbit_node_three stop_app
./rabbitmqctl -n rabbit_node_three reset
./rabbitmqctl -n rabbit_node_three join_cluster rabbit_node_one --ram
./rabbitmqctl -n rabbit_node_three start_app

查询集群状态:
./rabbitmqctl cluster_status -n rabbit_node_one

可以看到集群中三个节点已经正常启动,rabbit_node_three 设置为RAM内存节点,其他为磁盘节点(Disk and RAM Nodes)。RabbitMQ要求在集群中至少有一个磁盘节点,所有其他节点可以是内存节点,当节点加入或者离开集群时,必须要将该变更通知到至少一个磁盘节点。如果集群中唯一的一个磁盘节点崩溃的话,集群仍然可以保持运行,但是无法进行其他操作(增删改查),直到节点恢复。

 

测试集群节点down掉情况:对rabbit_node_two 进行kill操作 和 恢复操作, 查询集群情况

[{nodes,[{disc,[[email protected]‘,
                ‘[email protected]‘]},
         {ram,[‘[email protected]]}]},
 {running_nodes,[[email protected]‘,
                 ‘[email protected]]},
 {cluster_name,<<"[email protected]">>},
 {partitions,[]},
 {alarms,[{[email protected],[]},
          {[email protected],[]}]}]
zhouguangfengdeMacBook-Pro:sbin zhouguangfeng$ ./rabbitmqctl -n rabbit_node_two start_app
Starting node [email protected]-Pro ...
zhouguangfengdeMacBook-Pro:sbin zhouguangfeng$ ./rabbitmqctl cluster_status -n rabbit_node_one
Cluster status of node [email protected]-Pro ...
[{nodes,[{disc,[[email protected]‘,
                ‘[email protected]‘]},
         {ram,[‘[email protected]]}]},
 {running_nodes,[[email protected]‘,
                 ‘[email protected],‘[email protected]‘]},
 {cluster_name,<<"[email protected]">>},
 {partitions,[]},
 {alarms,[{[email protected],[]},
          {[email protected],[]}]}]
zhouguangfengdeMacBook-Pro:sbin zhouguangfeng$ 

 可以看到rabbit_node_two节点down之后,集群正常工作。 当节点恢复之后,主动加入集群。

 

  • RabbitMQ配置haproxy负载均衡

1、配置RabbitMQ镜像功能

 使用Rabbit镜像功能,需要基于RabbitMQ策略来实现,策略是用来控制和修改群集范围的某个vhost队列行为和Exchange行为

zhouguangfengdeMacBook-Pro:~ zhouguangfeng$ cd /usr/local/Cellar/rabbitmq/3.7.5/sbin/
zhouguangfengdeMacBook-Pro:sbin zhouguangfeng$ ls
cuttlefish        rabbitmq-diagnostics    rabbitmq-plugins    rabbitmqadmin        run.sh
rabbitmq-defaults    rabbitmq-env        rabbitmq-server        rabbitmqctl
zhouguangfengdeMacBook-Pro:sbin zhouguangfeng$ ./rabbitmqctl set_policy -p hrsystem ha-allqueue "^" ‘{"ha-mode":"all"}‘ -n rabbit_node_one
Setting policy "ha-allqueue" for pattern "^" to "{"ha-mode":"all"}" with priority "0" for vhost "hrsystem" ...
zhouguangfengdeMacBook-Pro:sbin zhouguangfeng$

 

这行命令创建一个名称为hrsystem的vhost,策略名称为ha-allqueue,策略模式为 all 即复制到所有节点,包含新增节点,策略正则表达式为 “^” 表示所有匹配所有队列名称。

详情参考:http://www.rabbitmq.com/rabbitmqctl.8.html#Policy_Management

 

2、安装haproxy,使用mac下安装工具brew : brew install haproxy 

查看安装版本和目录:

zhouguangfengdeMacBook-Pro:/ zhouguangfeng$ haproxy -version
HA-Proxy version 1.8.12-8a200c7 2018/06/27
Copyright 2000-2018 Willy Tarreau <[email protected]>

zhouguangfengdeMacBook-Pro:/ zhouguangfeng$ cd /usr/local/Cellar/haproxy/1.8.12/
.brew/                       INSTALL_RECEIPT.json         README                       homebrew.mxcl.haproxy.plist  
CHANGELOG                    LICENSE                      bin/                         share/                       
zhouguangfengdeMacBook-Pro:/ zhouguangfeng$ cd /usr/local/Cellar/haproxy/1.8.12/bin/
zhouguangfengdeMacBook-Pro:bin zhouguangfeng$ ls
haproxy    run.sh
zhouguangfengdeMacBook-Pro:bin zhouguangfeng$

 

配置haproxy.cfg 并启动:

zhouguangfengdeMacBook-Pro:bin zhouguangfeng$ cd /usr/local/etc/
zhouguangfengdeMacBook-Pro:bin zhouguangfeng$ mkdir haproxy
zhouguangfengdeMacBook-Pro:bin zhouguangfeng$ cd haproxy/
zhouguangfengdeMacBook-Pro:haproxy zhouguangfeng$ vim haproxy.cfg  -- 内容如下

    mode http
    option httplog # 采用http日志格式
