3.啟動
[root@rabbitmq-1 ~]# systemctl daemon-reload
[root@rabbitmq-1 ~]# systemctl start rabbitmq-server
[root@rabbitmq-1 ~]# systemctl enable rabbitmq-server
啟動方式二:
[root@rabbitmq-1 ~]# /sbin/service rabbitmq-server status  ---查看狀態(tài)
[root@rabbitmq-1 ~]# /sbin/service rabbitmq-server start   ---啟動
每臺都操作開啟rabbitmq的web訪問界面：
[root@rabbitmq-1 ~]# rabbitmq-plugins enable rabbitmq_management

注意:在一臺機器操作
添加用戶和密碼
[root@rabbitmq-1 ~]# rabbitmqctl add_user soho soso
Creating user "soho" ...
...done.
設(shè)置為管理員
[root@rabbitmq-1 ~]# rabbitmqctl set_user_tags soho administrator
Setting tags for user "soho" to [administrator] ...
...done.
查看用戶
[root@rabbitmq-1 ~]# rabbitmqctl list_users
Listing users ...
guest   [administrator]
soho    [administrator]
...done.
此處設(shè)置權(quán)限時注意'.*'之間需要有空格 三個'.*'分別代表了conf權(quán)限，read權(quán)限與write權(quán)限 
例如：當(dāng)沒有給
soho設(shè)置這三個權(quán)限前是沒有權(quán)限查詢隊列，在ui界面也看不見
[root@rabbitmq-1 ~]# rabbitmqctl set_permissions -p "/" soho ".*" ".*" ".*"
Setting permissions for user "soho" in vhost "/" ...
...done.

[root@rabbitmq-1 ~]# cd /etc/rabbitmq/
[root@rabbitmq-1 rabbitmq]# cp /usr/share/doc/rabbitmq-server-3.7.10/rabbitmq.config.example /etc/rabbitmq/rabbitmq.config
[root@rabbitmq-1 rabbitmq]# ls
enabled_plugins  rabbitmq.config
[root@rabbitmq-1 rabbitmq]# vim rabbitmq.config #開啟用戶遠(yuǎn)程登錄
修改如下:

三臺機器都操作重啟服務(wù)服務(wù):
[root@rabbitmq-1 ~]# systemctl restart rabbitmq-server

4369 -- erlang端口
5672 --程序連接端口
15672 -- 管理界面ui端口
25672 -- server間內(nèi)部通信口

[root@rabbitmq-1 ~]# mkdir -p /data/rabbitmq/data
[root@rabbitmq-1 ~]# mkdir -p /data/rabbitmq/logs
[root@rabbitmq-1 ~]# chmod 777 -R /data/rabbitmq
[root@rabbitmq-1 ~]# chown rabbitmq.rabbitmq /data/ -R
創(chuàng)建配置文件:
[root@rabbitmq-1 ~]# vim /etc/rabbitmq/rabbitmq-env.conf
[root@rabbitmq-1 ~]# cat /etc/rabbitmq/rabbitmq-env.conf
RABBITMQ_MNESIA_BASE=/data/rabbitmq/data
RABBITMQ_LOG_BASE=/data/rabbitmq/logs
重啟服務(wù)
[root@rabbitmq-1 ~]# systemctl restart rabbitmq-server

如果執(zhí)行 rabbitmqctl stop_app 這條命令報錯:需要執(zhí)行：
chmod 400 .erlang.cookie
chown rabbitmq.rabbitmq .erlang.cookie

[root@rabbitmq-1 ~]# cat /var/lib/rabbitmq/.erlang.cookie
HOUCUGJDZYTFZDSWXTHJ
?scp的?式將rabbitmq-1節(jié)點的.erlang.cookie的值復(fù)制到其他兩個節(jié)點中。
~]# scp /var/lib/rabbitmq/.erlang.cookie root@192.168.50.139:/var/lib/rabbitmq/
~]# scp /var/lib/rabbitmq/.erlang.cookie root@192.168.50.140:/var/lib/rabbitmq/

在mq-2、mq-3執(zhí)?如下命令：
[root@rabbitmq-2 ~]# rabbitmqctl stop_app  #停止節(jié)點，切記不是停止服務(wù)
~]# rabbitmqctl reset   #如果有數(shù)據(jù)需要重置，沒有則不用
~]# rabbitmqctl join_cluster --ram rabbit@rabbitmq-1  
Clustering node 'rabbit@rabbitmq-2' with 'rabbit@rabbitmq-1' ...
~]# rabbitmqctl start_app  #啟動節(jié)點
Starting node 'rabbit@rabbitmq-2' ...

[root@rabbitmq-3 ~]# rabbitmqctl stop_app
Stopping node 'rabbit@rabbitmq-3' ...
[root@rabbitmq-3 ~]# rabbitmqctl reset
Resetting node 'rabbit@rabbitmq-3' ...
[root@rabbitmq-3 ~]# rabbitmqctl join_cluster --ram rabbit@rabbitmq-1
Clustering node 'rabbit@rabbitmq-3' with 'rabbit@rabbitmq-1' ...
[root@rabbitmq-3 ~]# rabbitmqctl start_app
Starting node 'rabbit@rabbitmq-3' ...

?（1）默認(rèn)rabbitmq啟動后是磁盤節(jié)點，在這個cluster命令下，mq-2和mq-3是內(nèi)存節(jié)點，
mq-1是磁盤節(jié)點。
（2）如果要使mq-2、mq-3都是磁盤節(jié)點，去掉--ram參數(shù)即可。
（3）如果想要更改節(jié)點類型，可以使?命令rabbitmqctl change_cluster_node_type
disc(ram),前提是必須停掉rabbit應(yīng)?
注:
#如果有需要使用磁盤節(jié)點加入集群
 [root@rabbitmq-2 ~]# rabbitmqctl join_cluster  rabbit@rabbitmq-1
 [root@rabbitmq-3 ~]# rabbitmqctl join_cluster  rabbit@rabbitmq-1

在 RabbitMQ 集群任意節(jié)點上執(zhí)行 rabbitmqctl cluster_status來查看是否集群配置成功。
在mq-1磁盤節(jié)點上面查看
[root@rabbitmq-1 ~]# rabbitmqctl cluster_status

[root@rabbitmq-1 ~]# rabbitmqctl set_policy  ha-all "^" '{"ha-mode":"all"}'
Setting policy "ha-all" for pattern "^" to "{"ha-mode":"all"}" with priority "0" for vhost "/" ...

rabbitmqctl set_policy [-p Vhost] Name Pattern Definition
-p Vhost： 可選參數(shù)，針對指定vhost下的queue進(jìn)行設(shè)置（默認(rèn)根虛擬主機）
Name: policy的名稱，可以定義
Pattern: queue的匹配模式(正則表達(dá)式),也就是說會匹配一組。
Definition：鏡像定義，包括ha-mode,ha-params,ha-sync-mode
    ha-mode：指明鏡像隊列的模式
        all：表示在集群中所有的節(jié)點上進(jìn)行鏡像
        exactly：表示在指定個數(shù)的節(jié)點上進(jìn)行鏡像，
      ha-params：指定節(jié)點的個數(shù)
    ha-sync-mode：進(jìn)行隊列中消息的同步方式，有效值為automatic和manual，一般為自動同步
    ha-params：ha-mode模式需要用到的參數(shù)
案例:
例如，對隊列名稱以hello開頭的所有隊列進(jìn)行鏡像，并在集群的兩個節(jié)點上完成鏡像，policy的設(shè)置命令為： 
rabbitmqctl set_policy hello-ha “^hello” ‘{“ha-mode”:”exactly”,”ha-params”:2,”ha-sync-mode”:”automatic”}'

[root@rabbitmq-1 ~]# rabbitmqctl set_policy ha-all-1 -p test "^" '{"ha-mode":"all"}'
Setting policy "ha-all-1" for pattern "^" to "{"ha-mode":"all"}" with priority "0" for vhost "test" ...
