CentOs 7.3中搭建RabbitMQ 3.6单机多实例服务的步骤与使用
<p><span><strong>rabbitmq简介</strong></span></p>
<p>
rabbitmq是一个开源的amqp实现，服务器端用erlang语言编写，支持多种客户端，如：python、ruby、.net、java、jms、c、php、actionscript、xmpp、stomp等，支持ajax。用于在分布式系统中存储转发消息，在易用性、扩展性、高可用性等方面表现不俗。</p>
<p>
amqp，即advanced message queuing protocol，高级消息队列协议，是应用层协议的一个开放标准，为面向消息的中间件设计。消息中间件主要用于组件之间的解耦，消息的发送者无需知道消息使用者的存在，反之亦然。</p>
<p>
amqp的主要特征是面向消息、队列、路由（包括点对点和发布/订阅）、可靠性、安全。</p>

不想关闭防火墙，就开放15672端口,设置之后可以通过网页方式管理mq</p>
<p>
安装安装iptables防火墙</p>

添加用户</p>
<p>
处于安全的考虑，guest这个默认的用户只能通过http://localhost:15672 来登录，其他的ip无法直接使用这个账号。 这对于服务器上没有安装桌面的情况是无法管理维护的，除非通过在前面添加一层代理向外提供服务，这个又有些麻烦了，这里通过配置文件来实现这个功能</p>

<span><strong>rabbitmq的用户角色分类：</strong></span></p>
<p>
none、management、policymaker、monitoring、administrator</p>
<p>
rabbitmq各类角色描述：</p>
<p>
none</p>
<blockquote>
<p>
不能访问 management plugin</p>
</blockquote>
<p>
management</p>
<blockquote>
<p>
用户可以通过amqp做的任何事外加：<br>
列出自己可以通过amqp登入的virtual hosts <br>
查看自己的virtual hosts中的queues, exchanges 和 bindings<br>
查看和关闭自己的channels 和 connections<br>
查看有关自己的virtual hosts的“全局”的统计信息，包含其他用户在这些virtual hosts中的活动。</p>
</blockquote>
<p>
policymaker</p>
<blockquote>
<p>
management可以做的任何事外加：<br>
查看、创建和删除自己的virtual hosts所属的policies和parameters</p>
</blockquote>
<p>
monitoring</p>
<blockquote>
<p>
management可以做的任何事外加：<br>
列出所有virtual hosts，包括他们不能登录的virtual hosts<br>
查看其他用户的connections和channels<br>
查看节点级别的数据如clustering和memory使用情况<br>
查看真正的关于所有virtual hosts的全局的统计信息</p>
</blockquote>
<p>
administrator</p>
<blockquote>
<p>
policymaker和monitoring可以做的任何事外加:<br>
创建和删除virtual hosts<br>
查看、创建和删除users<br>
查看创建和删除permissions<br>
关闭其他用户的connections</p>
</blockquote>
<p>
<span><strong>设置权限</strong></span></p>
<p>
该用户无权访问任何虚拟主机</p>
<p>

这样的话你可以通过：http://192.168.161.161:15672/#/，http://192.168.161.161:15673/#/ ，http://192.168.161.161:15674/#/ 访问web查看相关节点是否真的存在。下面就是如何实现集群操作了。</p>
<p>
<span><strong>集群操作</strong></span></p>
<p>
把节点rabbit1 加入 rabbit中</p>
<p>
1.停止第二个节点的应用程序</p>
<div>
<div>
<div id="highlighter_348741">
<div>
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>
1</div>
</td>
<td>
<div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit1@master01 stop_app</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
2.重新设置第二个节点的元数据和状态为清空状态。</p>
<div>
<div>
<div id="highlighter_117807">
<div>
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>
1</div>
</td>
<td>
<div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit1@master01 reset</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
3.加入第一节点</p>
<div>
<div>
<div id="highlighter_792513">
<div>
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>
1</div>
</td>
<td>
<div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit1@master01 join_cluster rabbit@localhost</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
4.重新启动第二节点</p>
<div>
<div>
<div id="highlighter_46736">
<div>
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>
1</div>
</td>
<td>
<div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit1@master01 start_app</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
现在再次登陆web界面你可以到web端看到集群已经存在了！！！</p>
<p>
把节点rabbit2 加入 rabbit中</p>
<p>
同如上步骤的1234：其中注意点是，如果你需要设置第三个集群节点为内存模式，而非磁盘模式，可以参考当前版本的命令提示，在最后加上 –ram 参数</p>
<p>
添加第三节点的完整命令</p>
<div>
<div>
<div id="highlighter_384548">
<div>
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>
1</div>
<div>
2</div>
<div>
3</div>
<div>
4</div>
</td>
<td>
<div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit2@master01 stop_app</code>
</div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit2@master01 reset</code>
</div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit2@master01 join_cluster rabbit@master01</code>
</div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit2@master01 start_app</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
注意：如上第三步，如果你要设置第三个集群节点为内存模式，而非磁盘模式，那就需要 --ram</p>
<div>
<div>
<div id="highlighter_593447">
<div>
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td>
<div>

</td>
<td>
<div>
<div>
<code>.</code><code>/rabbitmqctl</code> <code>-n rabbit2@master01 join_cluster rabbit@master01 --</code><code>ram</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>

到web端看下效果吧！！！</p>

至此，集群搭建完毕。</p>
