RabbitMQ相关端口
•4369 (epmd)
•5672, 5671 (AMQP 0-9-1 and 1.0 without and with TLS)
•25672. This port used by Erlang distribution for inter-node and CLI tools communication and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). Seenetworking guide for details.
•15672 (if management plugin is enabled)
•61613, 61614 (if STOMP is enabled)
•1883, 8883 (if MQTT is enabled)

安装RabbitMQ
软件版本：
[root@node139 ~]# wget
[root@node139 ~]# rpm --import https://www.rabbitmq.com/rabbitmq-signing-key-public.asc
[root@node139 ~]# yum install rabbitmq-server-3.6.6-1.el7.noarch.rpm
启动服务
[root@node139 ~]# systemctl enable rabbitmq-server.service
[root@node139 ~]# systemctl start rabbitmq-server.service
启用RabbitMQ监控插件
[root@node139 ~]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
mochiweb
webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management
Applying plugin configuration to rabbit@node139... started 6 plugins.
[root@node139 ~]# netstat -apn | grep 15672
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 4119/beam.smp
RabbitMQ用户管理
添加用户（用户名root，密码admin）
[root@node139 ~]# rabbitmqctl add_user admin admin
设置用户角色（设置admin用户为管理员角色）
[root@node139 ~]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
设置用户权限（设置admin用户配置、写、读的权限）
[root@node139 ~]# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...
删除用户（删除guest用户）
[root@node139 ~]# rabbitmqctl delete_user guest
RabbitMQ集群配置
集群配置在单机配置完成的基础上进行
以下以node140为例，node132需要做同样的操作
•添加/etc/hosts条目
在node132、node139、node140里的/etc/hosts文件中分别添加：
192.168.190.132 node132
192.168.190.139 node139
192.168.190.140 node140
•设置每个节点Cookie
Rabbitmq的集群是依赖于erlang的集群来工作的，所以必须先构建起erlang的集群环境。Erlang的集群中各节点是通过一个magic cookie来实现的，这个cookie存放在 /var/lib/rabbitmq/.erlang.cookie 中，文件是400的权限。所以必须保证各节点cookie保持一致，否则节点之间就无法通信
[root@node140 /]# echo -n "AZVOCZYZZBVFLBPTBXU" > /var/lib/rabbitmq/.erlang.cookie
[root@node140 ~]# chown rabbitmq:root /var/lib/rabbitmq/.erlang.cookie
[root@node140 /]# chmod 600 /var/lib/rabbitmq/.erlang.cookie
[root@node140 /]# cat /var/lib/rabbitmq/.erlang.cookie
AZVOCZYZZBVFLBPTBXU
启动服务
[root@node140 ~]# systemctl start rabbitmq-server.service
[root@node140 ~]# rabbitmq-server -detached
开通防火墙
[root@node140 ~]# firewall-cmd --permanent --add-port={4369/tcp,25672/tcp}
success
[root@node140 ~]# firewall-cmd --reload
success
•加入集群
默认是磁盘节点，如果是内存节点的话，需要加--ram参数
[root@node140 ~]# rabbitmqctl stop_app
Stopping node rabbit@node140 ...
[root@node140 ~]# rabbitmqctl join_cluster rabbit@node139
Clustering node rabbit@node140 with rabbit@node139 ...
[root@node140 ~]# rabbitmqctl start_app
Starting node rabbit@node140 ...
•设置镜像策略
[root@node140 ~]# rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all","ha-sync-mode":"automatic"}'
Setting policy "ha-all" for pattern "^" to "{\"ha-mode\":\"all\",\"ha-sync-mode\":\"automatic\"}" with priority "0" …
启用RabbitMQ监控插件
cluster搭建起来后若在web管理工具中rabbitmq_management的Overview的Nodes部分看到"Node statistics not available"的信息，说明在该节点上web管理插件还未启用。
[root@node140 ~]# rabbitmq-plugins enable rabbitmq_management
集群配置好后，可以在 RabbitMQ 任意节点上执行下面的命令来查看是否集群配置成功。
[root@node140 ~]# rabbitmqctl cluster_status
其它节点需要做同样的操作

安装中遇到的问题：
这个/var/lib/rabbitmq/.erlang.cookie文件需要修改文件所有者和文件的权限为rw，否则rabbitmq服务无法启动；
