环境准备
基于centos7.5，自动分区，基础设施服务，两个虚机
配置ip 、route 、dns
以下以node1为例，node2同理
[root@localhost /]# hostname node1
[root@localhost /]# hostname
node1
[root@localhost /]#
[root@localhost /]# cat etc/hosts
#在node1的hosts文件里增加：
192.168.27.124 node1
192.168.27.157 node2
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 node1
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 node1
[root@localhost /]#

集群设置：
在两个节点上rabbitmqctl stop
将node1中的 erlang.cookie 复制到 node2中：
[root@node1 ~]# find / -name ".erlang.cookie"
/var/lib/rabbitmq/.erlang.cookie
[root@node1 ~]# cat /var/lib/rabbitmq/.erlang.cookie
XXZDFERERTFDFSEEM [root@node1 ~]# scp /var/lib/rabbitmq/.erlang.cookie root@node2:/var/lib/rabbitmq
关闭防火墙（否则提示连接不上）：
systemctl stop firewalld
systemctl disable firewalld
在两个节点上 rabbitmq-server -detached
查看集群状态
[root@node1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@node1 ...
[{nodes,[{disc,[rabbit@node1]}]},
{running_nodes,[rabbit@node1]},
{cluster_name,<<"rabbit@node1">>},
{partitions,[]},
{alarms,[{rabbit@node1,[]}]}]
[root@node1 ~]#
在node2上
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@node1
rabbitmqctl start_app
其中–ram指的是作为内存节点,要是想做为磁盘节点的话,就不用加–ram这个参数了,把第3行写成这样就好了
PS:只要在节点列表里包含了本身，它就成为一个磁盘节点。在RabbitMQ集群里，必须至少有一个磁盘节点存在。
查看集群状态
[root@node1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@node1 ...
[{nodes,[{disc,[rabbit@node1,rabbit@node2]}]},
{running_nodes,[rabbit@node2,rabbit@node1]},
{cluster_name,<<"rabbit@node1">>},
{partitions,[]},
{alarms,[{rabbit@node2,[]},{rabbit@node1,[]}]}]
[root@node1 ~]#
添加用户
由于guest这个用户,只能在本地访问,所以我们要新增一个用户并赋予权限
添加管理员账号（用户名密码都为admin）：
rabbitmqctl add_user admin admin
添加权限（使admin用户对虚拟主机“/” 具有所有权限）:
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
分配用户标签(管理员组）：
rabbitmqctl set_user_tags admin administrator
查看列举用户列表：
rabbitmqctl list_users
配置之后，然后就可以远程访问了，然后可直接配置用户权限等信息，到此,就可以通过 使用admin admin 进行登陆了。
到这里的话，每个节点是作为单独的一台RabbitMQ存在的，也可以正常提供服务了。
如果有需要修改密码操作如下（后两个参数为用户名和密码）：
rabbitmqctl change_password Username Newpassword
此时就可以使用账号远程登录了：
注意：这里添加用户后，登录任意一台集群环境web端都可以进去，也就是用户是针对所有集群机器的
问题：

解决办法：
1) ps -aux|grep rabbitmq //杀掉除grep外的pid
