OpenStack HA集群2

　　1、安装RabbitMQ-server
　　[root@controller1 ~]# yum install -y erlang rabbitmq-server
　　[root@controller1 ~]# systemctl start rabbitmq-server.service
　　[root@controller1 ~]# systemctl enable rabbitmq-server.service
　　[root@controller1 ~]# systemctl status rabbitmq-server.service
　　[root@controller1 ~]# systemctl list-unit-files | grep rabbitmq
　　rabbitmq-server.service                       enabled
　　以上三个节点同时进行

　　[root@controller1 ~]# rabbitmqctl add_user openstack zoomtech
　　Creating user "openstack" ...
　　[root@controller1 ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
　　Setting permissions for user "openstack" in vhost "/" ...
　　

　　[root@controller1 ~]# /usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent
　　The following plugins have been enabled:
　　  webmachine
　　  rabbitmq_web_dispatch
　　  rabbitmq_management_agent
　　  rabbitmq_management
　　  mochiweb
　　  amqp_client
　　Applying plugin configuration to rabbit@controller1... failed.
　　 * Could not contact node rabbit@controller1.
　　   Changes will take effect at broker restart.
　　 * Options: --online  - fail if broker cannot be contacted.
　　            --offline - do not try to contact broker.
　　[root@controller1 ~]# systemctl restart rabbitmq-server.service
　　[root@controller1 ~]# systemctl status rabbitmq-server.service

　　新增一个用户，在三个节点中操作
　　[root@controller1 ~]# rabbitmqctl add_user mqadmin mqadmin
　　Creating user "mqadmin" ...
　　[root@controller1 ~]# rabbitmqctl set_permissions -p / mqadmin ".*" ".*" ".*"
　　Setting permissions for user "mqadmin" in vhost "/" ...
　　[root@controller1 ~]# rabbitmqctl status
　　

　　复制.erlang.coolie到controller2和controller3
　　[root@controller1 ~]# scp /var/lib/rabbitmq/.erlang.cookie controller2:/var/lib/rabbitmq/.erlang.cookie
　　[root@controller1 ~]#
　　[root@controller1 ~]# scp /var/lib/rabbitmq/.erlang.cookie controller3:/var/lib/rabbitmq/.erlang.cookie
　　

　　将controller2加入到controller1集群中
　　[root@controller2 ~]# systemctl restart rabbitmq-server.service
　　

　　[root@controller2 ~]# rabbitmqctl stop_app
　　Stopping node rabbit@controller2 ...
　　

　　[root@controller2 ~]# rabbitmqctl join_cluster --ram rabbit@controller1
　　Clustering node rabbit@controller2 with rabbit@controller1 ...
　　

　　[root@controller2 ~]# rabbitmqctl start_app
　　Starting node rabbit@controller2 ...
　　

　　将controller3加入到controller1集群中
　　[root@controller3 ~]# systemctl restart rabbitmq-server.service
　　

　　[root@controller3 ~]# rabbitmqctl stop_app
　　Stopping node rabbit@controller3 ...
　　

　　[root@controller3 ~]# rabbitmqctl join_cluster --ram rabbit@controller1
　　Clustering node rabbit@controller3 with rabbit@controller1 ...
　　

　　在Controller1上查看集群状态
　　[root@controller1 ~]# rabbitmqctl cluster_status
　　Cluster status of node rabbit@controller1 ...
　　[{nodes,[{disc,[rabbit@controller1]},
　　         {ram,[rabbit@controller3,rabbit@controller2]}]},
　　 {running_nodes,[rabbit@controller3,rabbit@controller2,rabbit@controller1]},
　　 {cluster_name,<<"rabbit@controller1">>},
　　 {partitions,[]},
　　 {alarms,[{rabbit@controller3,[]},
　　          {rabbit@controller2,[]},
　　          {rabbit@controller1,[]}]}]
　　

　　[root@controller2 ~]# rabbitmqctl cluster_status
　　Cluster status of node rabbit@controller2 ...
　　[{nodes,[{disc,[rabbit@controller1]},
　　         {ram,[rabbit@controller3,rabbit@controller2]}]},
　　 {running_nodes,[rabbit@controller3,rabbit@controller1,rabbit@controller2]},
　　 {cluster_name,<<"rabbit@controller1">>},
　　 {partitions,[]},
　　 {alarms,[{rabbit@controller3,[]},
　　          {rabbit@controller1,[]},
　　          {rabbit@controller2,[]}]}]
