rabbitmq信息中枢

所有组件通信的时候 实用 AMQP 高级消息队列
qpid
rabbitmq    端口5672       sll加密 5671

192.168.1.201       h1.hequan.com     h1 192.168.1.202       h2.hequan.com     h2 192.168.1.203       h3.hequan.com     h3

在h3上操作  配置YUM源   把openstack软件包上传到openstack目录下

[openstack] name=openstack baseurl=file:///openstack enabled=1 gpgcheck=0 yum clean all yum makecache [iyunv@h1 yum.repos.d]# yum  install -y rabbitmq-server.noarch

[iyunv@h1 keystone]# egrep  -v  '^$|^#'  keystone.conf  | grep rabbit [oslo_messaging_rabbit] rabbit_host = localhost rabbit_port = 5672 rabbit_hosts = localhost:5672 rabbit_use_ssl = False rabbit_userid = guest    #默认用户 rabbit_password = guest rabbit_virtual_host = / rabbit_ha_queues = False [iyunv@h3 ~]# cd /etc/rabbitmq/ [iyunv@h3 rabbitmq]# ls rabbitmq.config             ##配置文件 [iyunv@h1 rabbitmq]# cat rabbitmq-env.conf NODE_PORT=5672

可以用web管理

[iyunv@h3 rabbitmq]# rabbitmq-plugins  list   ##查看插件 [iyunv@h3 rabbitmq]# rabbitmq-plugins   enable   rabbitmq_management  ##启用管理插件 The following plugins have been enabled:   mochiweb   webmachine   rabbitmq_web_dispatch   amqp_client   rabbitmq_management_agent   rabbitmq_management Plugin configuration has changed. Restart RabbitMQ for changes to take effect. [iyunv@h3 rabbitmq]# systemctl  restart rabbitmq-server.service [iyunv@h3 rabbitmq]# netstat -lntup | grep 15672 tcp        0      0 0.0.0.0:15672     0.0.0.0:*               LISTEN      1976/beam.smp
