RabbitMQ安装

一般来说安装 RabbitMQ 之前要安装 Erlang ，可以去Erlang官网下载。接着去RabbitMQ官网下载安装包，之后解压缩即可。

查看linux系统是32位还是64位
file /sbin/init 或者 file /bin/ls
示例：
[root@niu lib]# file /bin/ls
/bin/ls: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=056dda3f1b77919163a7de5563a2b9d9d245554c, stripped

RabbitMQ yum 安装

在这里，我们将通过设置repository , 以 CentOS 8 为例，安装

1、添加repository

输入命令:

vi   /etc/yum.repos.d/rabbmitmq.repo    

加入以下内容：

##
## Zero dependency Erlang RPM
##

2、使用yum安装

更新Yum包

yum update -y
yum -q makecache -y --disablerepo='*' --enablerepo='rabbitmq_erlang-noarch' --enablerepo='rabbitmq_server-noarch'

安装依赖

yum install socat logrotate -y

安装erlang

yum  install erlang 

安装rabbitmq

yum install rabbitmq-server

3、测试启动

查看状态

systemctl status rabbitmq-server.service
或者
service rabbitmq-server status

启动服务

systemctl  start rabbitmq-server.service
或者
service rabbitmq-server start

停止服务

systemctl stop rabbitmq-server.service
或者
service rabbitmq-server stop

重启服务

systemctl  restart rabbitmq-server.service      
或
service rabbitmq-server restart  

4、安装插件

进入目录：

cd  /usr/lib/rabbitmq/bin

./rabbitmq-plugins enable rabbitmq_management

重启服务：

systemctl  restart rabbitmq-server.service     
或
service rabbitmq-server restart

访问：

http://ip:15672     使用guest/guest登录

5、RabbitMQ用户角色及权限控制

RabbitMQ角色分为以下几种：

角色	描述
none	不能访问 management plugin
management	普通管理员 用户可以通过AMQP做的任何事 列出自己可以通过AMQP登入的virtual hosts 查看自己的virtual hosts中的queues, exchanges 和 bindings 查看和关闭自己的channels 和 connections 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。
policymaker	策略制定者 management可以做的任何事 查看、创建和删除自己的virtual hosts所属的policies和parameters
monitoring	监控者 management可以做的任何事 列出所有virtual hosts，包括他们不能登录的virtual hosts 查看其他用户的connections和channels 查看节点级别的数据如clustering和memory使用情况 查看真正的关于所有virtual hosts的全局的统计信息
administrator	管理员 policymaker和monitoring可以做的任何事 创建和删除virtual hosts 查看、创建和删除users 查看创建和删除permissions 关闭其他用户的connections

6、创建用户并授权

创建用户

rabbitmqctl add_user    username  password

授予角色

rabbitmqctl set_user_tags  username  角色名称

ps: 如果多个角色，用空格隔开

修改密码

rabbitmqctl change_password username  password

删除用户

rabbitmqctl delete_user username

查看用户

rabbitmqctl list_users
