rabbitmq最新版本在外部的访问权限上进行了进一步的控制，其中默认情况下，guest用户只能通过本地loopback端口访问
为了在外部对rabbitmq进行连接和访问，需要新增用户，对用到的命令进行简单记录
rabbitmqctl add_user<username><userpass>
rabbitmqctl add_vhost<path>
rabbitmqctl set_user_tags<username>administrator
rabbitmqctl set_permissions -p<path><username>".*" ".*" ".*"
rabbitmqctllist_connections---用于查看当前的连接
rabbitmqctllist_queues---会列出所有队列名称，后边可能还会带着这个队列当前消息数
rabbitmqctlstatus---查看当前队列信息
rabbitmqctl stop_app
rabbitmqctlreset/force_reset
rabbitmqctl start_app
rabbitmqctl-p${vhost-name}purge_queue${queue-name}

给centos安装epel yum 源
# rpm -ivh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
安装erlang运行环境
# yum install erlang
安装rabbitmq server
# rpm --import http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
# rpm -ivh http://www.rabbitmq.com/releases/rabbitmq-server/v3.0.0/rabbitmq-server-3.0.0-1.noarch.rpm
打开server
# chkconfig rabbitmq-server on
# rabbitmqctl status

nodes in question: [rabbit@devnote]
hosts, their running nodes and ports:
- devnote: [{rabbitmqctl24923,51045}]
current node details:
- node name: rabbitmqctl24923@devnote
- home dir: /var/lib/rabbitmq
- cookie hash: TblHThacrBHJzl5Vt7Y4Ww==
执行命令：
# /sbin/service rabbitmq-server stop
# /sbin/service rabbitmq-server start
# rabbitmqctl status 测试正确
查看所有队列信息
# rabbitmqctl list_queues
关闭应用
# rabbitmqctl stop_app
启动应用，和上述关闭命令配合使用，达到清空队列的目的
# rabbitmqctl start_app
