1、安装软件包

yum install erlang rabbitmq-server –y

2、启动服务并设置开机启动

systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

3、创建用户

rabbitmqctl add_user openstack  Changeme_123

4、赋予用户权限

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

5、修改配置文件

cat <<END> /etc/rabbitmq/rabbitmq-env.conf
RABBITMQ_NODE_PORT=5672
ulimit -S -n 4096
RABBITMQ_SERVER_ERL_ARGS="+K true +A30 +P 1048576 -kernel inet_default_connect_options [{nodelay,true},{raw,6,18,<<5000:64/native>>}] -kernel inet_default_listen_options [{raw,6,18,<<5000:64/native>>}]"
RABBITMQ_NODE_IP_ADDRESS=172.16.8.60
END

替换为本机的IP

6、将节点node1的cookie拷贝到其他节点上

scp /var/lib/rabbitmq/.erlang.cookie node2:/var/lib/rabbitmq/.erlang.cookie
scp /var/lib/rabbitmq/.erlang.cookie node3:/var/lib/rabbitmq/.erlang.cookie

7、将其他节点加入到集群中
在第二个节点中

systemctl restart rabbitmq-server
rabbitmqctl stop_app

rabbitmqctl join_cluster --ram rabbit@node1

rabbitmqctl start_app

第三个节点

systemctl restart rabbitmq-server
rabbitmqctl stop_app

rabbitmqctl join_cluster --ram rabbit@node1

rabbitmqctl start_app

8、查看集群状态

rabbitmqctl cluster_status

9、打开管理界面

rabbitmq-plugins enable rabbitmq_management
systemctl restart rabbitmq-server

10、赋予管理员权限

rabbitmqctl set_user_tags openstack   administrator

11、登录界面
