环境准备

本次实验使用的是VMvare虚拟机。详情如下
hostname: node1.server
ip地址:192.168.0.150 网卡:eth0,eth1
系统及硬件:CentOS 7.2 内存2G,硬盘50G

一、 什么是RabbitMq

  消息队列又称为MQ,应用程序间的消息通信工具,其有利于程序解耦、多语言集成、异步通信、扩展和简单负载均衡等,是生产-消费者模型的典型代表。常见MQ产品有RabbitMQ ZeroMQ Kafka等等。

RabbitMQ,老牌MQ产品,基于erlang语言,实现对AMQP等协议的支持,重量级,适合企业级应用开发;Kafka,linkedin开源MQ产品,追求高吞吐量,适合于大量数据的收集业务,如互联网业务产生的大量日志数据;ZeroMQ,号称最快的MQ,提供了一套异步消息通信库,可实现RabbitMQ不能实现的高级复杂队列;Kafka和RabbitMQ都需要搭建消息代理服务器,采用中间件模式。ZeroMQ采用非中间件模式,不需要搭建消息代理服务器。

二、 部署

# yum install gcc gcc -c++ make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel zlib zlib-devel xmlto libgnomeui-devel nc libX* java* tk unixODBC unixODBC-devel -y

# yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm -y

# yuminstall rabbitmq-server -y

# systemctl enable rabbitmq-server.service

# systemctl start rabbitmq-server.service

Job for rabbitmq-server.service failed becausethe control process exited with error code. See "systemctl statusrabbitmq-server.service"and"journalctl -xe" for details.

解决方法:

修改主机名和hosts

修改前:

# hostnamectl status
   Static hostname: node1.server
         Icon name: computer-vm
           Chassis: vm
        Machine ID: d359f0058624494aa3c144477c6d97b8
           Boot ID: bdd32e5df98a41259a441a079c0c44b3
    Virtualization: vmware
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-327.el7.x86_64

      Architecture: x86-64                              

修改后:

# hostnamectl --static set-hostname node1                       

# hostnamectl status                                 

   Static hostname: node1
Transient hostname: node1.server
         Icon name: computer-vm
           Chassis: vm
        Machine ID: d359f0058624494aa3c144477c6d97b8
           Boot ID: bdd32e5df98a41259a441a079c0c44b3
    Virtualization: vmware
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-327.el7.x86_64
      Architecture: x86-64
# cat /etc/hosts
127.0.0.1  localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.0.150 node1                                                


启用Rabbitmq的web管理插件

  RabbitMQ提供了一套插件机制,方便功能扩展。这里介绍一个最常用的:rabbitmq_management。这款插件提供了完善的web管理和监控功能,提供了各项指标。

# rabbitmq-plugins enable rabbitmq_management

The following plugins have been enabled:
Mochiweb
Webmachine
rabbitmq_web_dispatch
amqp_client
rabbitmq_management_agent
rabbitmq_management

Applying plugin configuration to rabbit@node1... started 6 plugins.                                                                                                                


新建Rabbitmq用户并授权

# rabbitmqctl add_user openstack openstack

Creating user "openstack" ...

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

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

# systemctl restart rabbitmq-server.service
查看Rabbit的端口,其中5672是服务端口,15672是web管理端口,25672是做集群的端口

# ss -tunlp|grep 5672

在web界面添加openstack用户,设置权限,首次登陆必须使用账号和密码,必须都是guest
