OpenStack HA集群2-RabbitMQ集群

Posted 2020-09-01

1、安装RabbitMQ-server

[[email protected] ~]# yum install -y erlang rabbitmq-server

[[email protected] ~]# systemctl start rabbitmq-server.service

[[email protected] ~]# systemctl enable rabbitmq-server.service

[[email protected] ~]# systemctl status rabbitmq-server.service

[[email protected] ~]# systemctl list-unit-files | grep rabbitmq

rabbitmq-server.service                       enabled

以上三个节点同时进行

[[email protected] ~]# rabbitmqctl add_user openstack zoomtech

Creating user "openstack" ...

[[email protected] ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"

Setting permissions for user "openstack" in vhost "/" ...

[[email protected] ~]# /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 [email protected] failed.

 * Could not contact node [email protected]

   Changes will take effect at broker restart.

 * Options: --online  - fail if broker cannot be contacted.

            --offline - do not try to contact broker.

[[email protected] ~]# systemctl restart rabbitmq-server.service

[[email protected] ~]# systemctl status rabbitmq-server.service

登录：http://192.168.17.132:15672/#/

Username： guest      Password：guest

新增一个用户，在三个节点中操作

[[email protected] ~]# rabbitmqctl add_user mqadmin mqadmin

Creating user "mqadmin" ...

[[email protected] ~]# rabbitmqctl set_permissions -p / mqadmin ".*" ".*" ".*"

Setting permissions for user "mqadmin" in vhost "/" ...

[[email protected] ~]# rabbitmqctl status

复制.erlang.coolie到controller2和controller3

[[email protected] ~]# scp /var/lib/rabbitmq/.erlang.cookie controller2:/var/lib/rabbitmq/.erlang.cookie

[[email protected] ~]#

[[email protected] ~]# scp /var/lib/rabbitmq/.erlang.cookie controller3:/var/lib/rabbitmq/.erlang.cookie

将controller2加入到controller1集群中

[[email protected] ~]# systemctl restart rabbitmq-server.service

[[email protected] ~]# rabbitmqctl stop_app

Stopping node [email protected] ...

[[email protected] ~]# rabbitmqctl join_cluster --ram [email protected]

Clustering node [email protected] with [email protected] ...

[[email protected] ~]# rabbitmqctl start_app

Starting node [email protected] ...

将controller3加入到controller1集群中

[[email protected] ~]# systemctl restart rabbitmq-server.service

[[email protected] ~]# rabbitmqctl stop_app

Stopping node [email protected] ...

[[email protected] ~]# rabbitmqctl join_cluster --ram [email protected]

Clustering node [email protected] with [email protected] ...

在Controller1上查看集群状态

[[email protected] ~]# rabbitmqctl cluster_status

Cluster status of node [email protected] ...

[{nodes,[{disc,[[email protected]]},

         {ram,[[email protected],[email protected]]}]},

 {running_nodes,[[email protected],[email protected],[email protected]]},

 {cluster_name,<<"[email protected]">>},

 {partitions,[]},

 {alarms,[{[email protected],[]},

          {[email protected],[]},

          {[email protected],[]}]}]

[[email protected] ~]# rabbitmqctl cluster_status

Cluster status of node [email protected] ...

[{nodes,[{disc,[[email protected]]},

         {ram,[[email protected],[email protected]]}]},

 {running_nodes,[[email protected],[email protected],[email protected]]},

 {cluster_name,<<"[email protected]">>},

 {partitions,[]},

 {alarms,[{[email protected],[]},

          {[email protected],[]},
