接下来想研究一下mq消息队列，打算在linux上面弄，所以先安装一个Centos 7 ，推荐这个安装教程，感觉比较全面 blog.csdn.net/yiyihuazi/a…
[root@localhost ~]# 分别代表用户名（root），主机名（localhost），当前路径（~,当前用户的home目录），权限标志位（#代表root，$代表普通用户）
安装rpm包出现信赖错误: blog.csdn.net/jinyun1984/…

CentOS7.0 使用root登录桌面:blog.csdn.net/bolg_hero/a…
====================================================
启动服务:
systemctl start rabbitmq-server.service
查看服务状态:
systemctl status rabbitmq-server.service
停止服务:
systemctl stop rabbitmq-server.service
查看rabbit进程：
ps -ef | grep rabbit
哎， 坑实在太多了，好不容易才弄好了，大家如果在使用”systemctl“有以下问题可以参考下面的地址 serverfault.com/questions/9…
Error: unable to perform an operation on node 'rabbit@sXXX-XXX-XXX-XXX'. Please see diagnostics information and suggestions below.
Most common reasons for this are:
* Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
* CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
* Target node is not running
In addition to the diagnostics info below:
* See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
* Consult server logs on node rabbit@sXXX-XXX-XXX-XXX
DIAGNOSTICS

验证一下，我的地址是：http://192.168.183.128:15672，大家访问自己的地址就好，端口是15672
rabbitmq装好了，有时间就继续研究在Java中如何使用mq了。。。
