元数据
rabbitmq信息中枢
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 [[email protected] yum.repos.d]# yum install -y rabbitmq-server.noarch
[[email protected] ~]# systemctl start rabbitmq-server.service [[email protected] ~]# systemctl enable rabbitmq-server.service [[email protected] ~]# netstat -lntup | grep 5672 tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 1354/beam.smp tcp6 0 0 :::5672 :::* LISTEN 1354/beam.smp #使用这个
[[email protected] 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 [[email protected] ~]# cd /etc/rabbitmq/ [[email protected] rabbitmq]# ls rabbitmq.config ##配置文件 [[email protected] rabbitmq]# cat rabbitmq-env.conf NODE_PORT=5672
可以用web管理
[[email protected] rabbitmq]# rabbitmq-plugins list ##查看插件 [[email protected] 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. [[email protected] rabbitmq]# systemctl restart rabbitmq-server.service [[email protected] rabbitmq]# netstat -lntup | grep 15672 tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 1976/beam.smp

查看控制节点 网卡设置是否有问题
