rabbitmq-plugins enable rabbitmq_management
关闭管理界面
rabbitmq-plugins disable rabbitmq_management

RabbitMQ 用户管理:

设置管理员：sudo rabbitmqctl set_user_tags user1 administrator
删除用户：sudo rabbitmqctl delete_user user1
修改密码：sudo rabbitmqctl change_password user1 newpassword

RabbitMQ 权限管理
RabbitMQ权限是 vhost级别，默认 vhost：/
sudo rabbitmqctl set_permissions -p / user1 ".*" ".*" ".*"    #含义分别是configure、write、read    
查看权限
sudo rabbitmqctl list_permissions

RabbitMQ 队列管理
查看所有队列：sudo rabbitmqctl list_queues
查看 exchange：sudo rabbitmqctl list_exchanges

RabbitMQ 日志
日志路径：/var/log/rabbitmq/
常见的日志文件：
rabbit@hostname.log
rabbit@hostname_upgrade.log

RabbitMQ 网络端口
| 端口  | 用途      |
| ----- | ------   |
| 5672  | AMQP协议  |
| 15672 | Web管理   |
| 25672 | 集群通信  |

RabbitMQ 三个常见CLI工具区别
| 工具                 | 作用         						 |
| -------------------- | -----------             |
| rabbitmqctl          | 节点管理，本质是curl 封装 |
| rabbitmq-diagnostics | 故障诊断      				  	|
| rabbitmqadmin        | HTTP API 管理					 |

测试rabbitMQ（部署成功了，但要怎么测试？）
确认 RabbitMQ 已经安装成功：rabbitmqctl status
安装 rabbitmqadmin：wget http://你服务器的IP地址:15672/cli/rabbitmqadmin
赋予执行权限：chmod +x rabbitmqadmin
移动到系统路径：sudo mv rabbitmqadmin /usr/local/bin/

测试：rabbitmqadmin -u admin -p admin123 list queues
创建队列：创建队列：rabbitmqadmin -u admin -p admin123 declare queue name=test durable=true
发送测试消息：rabbitmqadmin -u admin -p admin123 publish routing_key=test payload="hello"
查看队列消息：rabbitmqadmin -u admin -p admin123 get queue=test

官方集群部署方案

参考链接：https://www.rabbitmq.com/docs/clustering

将多个单节点部署成集群，官方明确说了RabbitMQ 节点的识别方式：节点名称

当前环境：
[root@test01 ~]# rabbitmqctl status
Status of node rabbit@test01 ...
Runtime

OS PID: 49791
OS: Linux
Uptime (seconds): 2734
Is under maintenance?: false
RabbitMQ version: 4.2.4
RabbitMQ release series support status: see https://www.rabbitmq.com/release-information
Node name: rabbit@test01

设置主机名（非常重要）
123节点：sudo hostnamectl set-hostname rabbit1
124节点：sudo hostnamectl set-hostname rabbit2
125节点：sudo hostnamectl set-hostname rabbit3

配置 hosts 解析
三台机器都写：
cat >> /etc/hosts <<EOF
10.0.0.123 rabbit1
10.0.0.124 rabbit2
10.0.0.125 rabbit3
EOF

测试一下：ping rabbit1

同步 Erlang Cookie（最关键）
实现RabbitMQ 节点之间认证靠：在 rabbit1查看：
cat /var/lib/rabbitmq/.erlang.cookie
scp /var/lib/rabbitmq/.erlang.cookie root@10.0.0.124:/var/lib/rabbitmq/
scp /var/lib/rabbitmq/.erlang.cookie root@10.0.0.125:/var/lib/rabbitmq/
修改权限：sudo chmod 400 /var/lib/rabbitmq/.erlang.cookie
重启服务：systemctl restart rabbitmq-server

其它节点加入集群
在 rabbit2 执行：
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@rabbit1
rabbitmqctl start_app

在 rabbit3 执行：
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbit@rabbit1
rabbitmqctl start_app

查看集群状态：rabbitmqctl cluster_status
[root@test01 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@test01 ...
Basics

Cluster name: rabbit@test01
Total CPU cores available cluster-wide: 6

Cluster Tags

(none)

Disk Nodes

rabbit@test01
rabbit@test02
rabbit@test03

Running Nodes

rabbit@test01
rabbit@test02
rabbit@test03

Versions

rabbit@test01: RabbitMQ 4.2.4 on Erlang 27.3.4.6
rabbit@test02: RabbitMQ 4.2.4 on Erlang 27.3.4.6
rabbit@test03: RabbitMQ 4.2.4 on Erlang 27.3.4.6

CPU Cores

Node: rabbit@test01, available CPU cores: 2
Node: rabbit@test02, available CPU cores: 2
Node: rabbit@test03, available CPU cores: 2

Maintenance status

Node: rabbit@test01, status: not under maintenance
Node: rabbit@test02, status: not under maintenance
Node: rabbit@test03, status: not under maintenance

Web UI 也可以看到集群：http://ip:15672

其他节点没有启用 rabbitmq_management_agent 这个插件，就会出现： Node statistics not available

ubt 以 apt 部署方式（可能版本旧）

1 安装 Erlang

RabbitMQ必须依赖 Erlang。

Ubuntu：

apt update
apt install erlang -y
apt install curl gnupg apt-transport-https -y
curl -1sLf 'https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/setup.deb.sh' | sudo -E bash
curl -1sLf 'https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/setup.deb.sh' | sudo -E bash

CentOS：

yum install erlang -y

2 安装 RabbitMQ

Ubuntu：

apt install rabbitmq-server -y
systemctl enable rabbitmq-server
systemctl start rabbitmq-server
systemctl status rabbitmq-server

CentOS：

yum install rabbitmq-server -y

启动：

systemctl enable rabbitmq-server
systemctl start rabbitmq-server

3 开启管理界面

rabbitmq-plugins enable rabbitmq_management

访问：

http://IP:15672

默认账号：

guest / guest

配置高可用队列

RabbitMQ默认：

队列只在一个节点

需要配置：

镜像队列 / Quorum Queue

推荐：

Quorum Queue

创建策略：

rabbitmqctl set_policy ha-all "^log." \
'{"ha-mode":"all"}'

Logstash连接RabbitMQ

Logstash配置：

input {
  rabbitmq {
    host => "10.0.0.123"
    queue => "logs"
    user => "log"
    password => "log123"
  }
}

Filebeat可以用：

output.rabbitmq

生产环境建议

一定要做：

1 负载均衡

前面加：

HAProxy

或

Nginx stream

2 监控

建议：

Prometheus + Grafana

3 磁盘

RabbitMQ是 磁盘IO敏感

建议：SSD
