腾讯云搭建Rabbit单机服务

RabbitMQ是基于Erlang语言开发的。
在安装RabbitMQ前，首先搭建好Erlang环境。

$ cd /opt
$ wget http://www.rabbitmq.com/releases/erlang/erlang-19.0.4-1.el7.centos.x86_64.rpm
#####本人获取连接文件包时，下载速度太慢，采取先下载到本地电脑，再使用x-ftp上传到服务器
$ yum install erlang-19.0.4-1.el7.centos.x86_64.rpm

安装Rabbit，

$ cd /opt
$ wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.10/rabbitmq-server-3.6.10-1.el7.noarch.rpm
$ yum install rabbitmq-server-3.6.10-1.el7.noarch.rpm

启动服务，

$ service rabbitmq-server start

查看服务状态

$ service rabbitmq-server status

$ service rabbitmq-server status
Redirecting to /bin/systemctl status rabbitmq-server.service

log中显示没有找到配置文件，自己创建这个文件

$ config file(s) : /etc/rabbitmq/rabbitmq.config (not found)

创建rabbitmq.config

$ cd /etc/rabbitmq/
$ vi rabbitmq.config

编辑保存如下内容(别忘了最后的“.”)：

[{rabbit, [{loopback_users, []}]}].

开启管理UI

$ /sbin/rabbitmq-plugins enable rabbitmq_management

重启服务

service rabbitmq-server restart

访问管理UI(注意外网登录要先开放5672/15672端口)

通过 http://ip:15672 使用guest,guest 进行登陆了

登陆成功

登陆成功

添加用户
命令格式

rabbitmqctl add_user <username> <newpassword>

$ rabbitmqctl add_user root 123456
Creating user "root"

用户授权

rabbitmqctl set_permissions -p "/" root ".*" ".*" ".*"

查看用户授权

$ rabbitmqctl list_permissions root

Listing permissions for user "root"
/   .*  .*  .*

添加角色
将root用户设置为administrator角色

$ rabbitmqctl set_user_tags root administrator
Setting tags for user "root" to [administrator]

查看当前用户列表

$ rabbitmqctl list_users
Listing users
guest    [administrator]
root    [administrator]

完成以上操作后，可以使用root身份登录管理UI http://ip:15672

Rabbit简单使用可参考# Spring Boot 中使用 RabbitMQ
