上课用tcp同步服务太考验服务器了，经常掉线、假死、连不上，逼得没办法改用消息队列了，之前用过mqtt，这回用RabbitMQ
1、安装rabbitMQ正常操作，中间安装homebrew时提示连接超时，换个网就好了。
2、远程访问rabbitMQ时说guest账号不能远程访问
3、新建一个administrator权限的用户，rabbitmqctl的命令提示command not found。
4、去.bash_profile里关联环境变量(和windows好像)
sudo vi ~/.bash_profile ，里加入
export PATH=/usr/local/Cellar/rabbitmq/3.7.5/sbin:$PATHwq! 成功
5、添加用户admin并设置权限。
6、本机运行连接报错，找不到so，应该是rabbitmq不支持x86硬件吧
7、用手机运行，报错：

8、用手机端浏览器访问10.23.195.5:15672 没问题，正常访问，有点蒙
https://www.oschina.net/question/1762811_2199005
9、15672端口是http访问端口amqp是5672
10、运行命令rabbitmqctl status，发现amqp确实是5672 http是15672，尴尬
11、改成5672后报错

12、查看一下5672端口被占用情况：
13、发现其他的都是机器地址+端口，就5672这个不是，妈的肯定是这儿有问题，找一下解决办法：
http://docs.celeryproject.org/en/latest/getting-started/brokers/rabbitmq.html
如果是dhcp的话，rabbitmq将会用非法的主机名，差不多就是这个意思了
14、直接Google {amqp,5672,"127.0.0.1"}，搜出一篇文章：
http://www.voidcn.com/article/p-xnkxpaiv-brb.html
15、修改后重启，bingo queues里有东西了，再看netstat -an|grep 5672
16、可以歇一会儿了
