安裝RabbitMQ
軟件版本：http://www.rabbitmq.com/releases/rabbitmq-server
[root@node139 ~]# wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.6/rabbitmq-server-3.6.6-1.el7.noarch.rpm
[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
啟動服務(wù)
[root@node139 ~]# systemctl enable rabbitmq-server.service
[root@node139 ~]# systemctl start rabbitmq-server.service
啟用RabbitMQ監(jiān)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用戶管理
添加用戶（用戶名root，密碼admin）
[root@node139 ~]# rabbitmqctl add_user admin admin
設(shè)置用戶角色（設(shè)置admin用戶為管理員角色）
[root@node139 ~]# rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator] ...
設(shè)置用戶權(quán)限（設(shè)置admin用戶配置、寫、讀的權(quán)限）
[root@node139 ~]# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/" ...
刪除用戶（刪除guest用戶）
[root@node139 ~]# rabbitmqctl delete_user guest
RabbitMQ集群配置
集群配置在單機配置完成的基礎(chǔ)上進行
以下以node140為例，node132需要做同樣的操作
?添加/etc/hosts條目
在node132、node139、node140里的/etc/hosts文件中分別添加：
192.168.190.132 node132
192.168.190.139 node139
192.168.190.140 node140
?設(shè)置每個節(jié)點Cookie
Rabbitmq的集群是依賴于erlang的集群來工作的，所以必須先構(gòu)建起erlang的集群環(huán)境。Erlang的集群中各節(jié)點是通過一個magic cookie來實現(xiàn)的，這個cookie存放在 /var/lib/rabbitmq/.erlang.cookie 中，文件是400的權(quán)限。所以必須保證各節(jié)點cookie保持一致，否則節(jié)點之間就無法通信
[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
啟動服務(wù)
[root@node140 ~]# systemctl start rabbitmq-server.service
[root@node140 ~]# rabbitmq-server -detached
開通防火墻
[root@node140 ~]# firewall-cmd --permanent --add-port={4369/tcp,25672/tcp}
success
[root@node140 ~]# firewall-cmd --reload
success
?加入集群
默認(rèn)是磁盤節(jié)點，如果是內(nèi)存節(jié)點的話，需要加--ram參數(shù)
[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 ...
?設(shè)置鏡像策略
[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" …
啟用RabbitMQ監(jiān)控插件
cluster搭建起來后若在web管理工具中rabbitmq_management的Overview的Nodes部分看到"Node statistics not available"的信息，說明在該節(jié)點上web管理插件還未啟用。
[root@node140 ~]# rabbitmq-plugins enable rabbitmq_management
集群配置好后，可以在 RabbitMQ 任意節(jié)點上執(zhí)行下面的命令來查看是否集群配置成功。
[root@node140 ~]# rabbitmqctl cluster_status
其它節(jié)點需要做同樣的操作

安裝中遇到的問題：
這個/var/lib/rabbitmq/.erlang.cookie文件需要修改文件所有者和文件的權(quán)限為rw，否則rabbitmq服務(wù)無法啟動；
