rabbitmq（centos 7)安装
<p>CentOS7 安装RabbitMQ
由于rabbitmq需要erlang环境，在安装前，先要安装好erlang，才能安装rabbitmq，然后下载插件，最后enable插件。</p>
<p>1、安装erlang</p>
<p>1.1 、安装erlang的依赖</p>
<p>yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel
yum install epel-release
yum install unixODBC unixODBC-devel wxBase wxGTK SDL wxGTK-gl</p>
<p>1.2、下载erlang rpm包</p>
<p>wget <a href="https://packages.erlang-solutions.com/erlang/rpm/centos/7/x86_64/esl-erlang_22.1.8-1~centos~7_amd64.rpm">https://packages.erlang-solutions.com/erlang/rpm/centos/7/x86_64/esl-erlang_22.1.8-1~centos~7_amd64.rpm</a></p>
<p>1.3、 安装</p>
<p>yum install esl-erlang_22.1.8-1~centos~7_amd64.rpm</p>
<p>1.4、验证安装</p>
<p>erl
1+1.
halt().
2、安装rabbitmq</p>
<p>2.1、下载和安装</p>
<p>wget <a href="https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-3.8.2-1.el7.noarch.rpm">https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.2/rabbitmq-server-3.8.2-1.el7.noarch.rpm</a>
rpm –import <a href="https://www.rabbitmq.com/rabbitmq-release-signing-key.asc">https://www.rabbitmq.com/rabbitmq-release-signing-key.asc</a>
yum install rabbitmq-server-3.8.2-1.el7.noarch.rpm</p>
<p>如果出现错误Error unpacking rpm package rabbitmq-server-3.8.2-1.el7.noarch。请重新下载rabbitmq-server-3.8.2-1.el7.noarch.rpm</p>
<p>2.2、设置开启自动启动和启动</p>
<p>chkconfig rabbitmq-server on
systemctl start rabbitmq-server
rabbitmqctl status
3、其他</p>
<p>运行如下的命令，增加用户admin，密码admin</p>
<p>[root@localhost sbin]# rabbitmqctl add_user admin admin
[root@localhost sbin]# rabbitmqctl set_user_tags admin administrator
[root@localhost sbin]# rabbitmqctl list_users</p>
<p>当我们开启了服务之后，我们通过远程访问地址 <a href="http://192.168.1.35:15672/">http://192.168.1.35:15672/</a> 可以看到</p>

<p>这个时候你可能很高兴，以为成功了，但是你通过默认用户guest和密码guest登录时会发现，登录失败！</p>
<p>开启管理界面
rabbitmq-plugins enable rabbitmq_management
安装webmqtt插件
rabbitmq-plugins enable rabbitmq_web_mqtt
只要启用rabbitmq的MQTT插件即可：
rabbitmq-plugins enable rabbitmq_mqtt
安装mqttjs demo插件
rabbitmq-plugins enable rabbitmq_web_mqtt_examples</p>

<p>然后就可以通过admin,进行登录访问了客户端了
下面演示一下关于在客户端页面进行的添加用户，分配权限的操作，不多说了直接上图演示如下：</p>

<p>是不是发现下图粉色框中的权限不同，这时候就要点击红色框中的 zhz11

这样对RabbitMq的用户赋权限问题就解决了！</p>
