1.手动配置安装源：
vim /etc/yum.repos.d/rabbitmq-erlang.repo
配置erlang安装源
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/19/el/6
gpgckeck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1
保存后执行命令：yum -y install erlang
2.获取rabbitmq包
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.4.1/rabbitmq-server-3.4.1-1.noarch.rpm
.安装：
rpm -ivh rabbitmq-server-3.4.1-1.noarch.rpm
启动服务
service rabbitmq-server start
service rabbitmq-server stop
service rabbitmq-server restart
3.开机自启
chkconfig rabbitmq-server on
4.复制mq配置文件
cp /usr/share/doc/rabbitmq-server-3.4.1/rabbitmq.config.example /etc/rabbitmq/
改名字：mv rabbitmq.config.example rabbitmq.config
去掉rabbitmq.config 行的{loopback_user,[]},的注释 并去掉逗号{loopback_user,[]}
5.开启web界面管理工具，并重启rabbitMQ
/etc/rabbitmq文件下启动后台管理页面命令：
rabbitmq-plugins enable rabbitmq_management
并重启服务：service rabbitmq-server restart
6.修改防火墙配置文件，开发15672和5672端口
15672：网页访问端口
5672：java程序访问mq时用到的端口
vim /etc/sysconfig/iptables
-A INPUT -p tcp -m tcp --dport 15672 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 5672 -j ACCEPT
重启iptalbes
service iptables restart
centos防火墙关闭firewall：
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
firewall-cmd --state #查看默认防火墙状态(关闭后显示notrunning，开启后显示running)
7.访问
http://127.0.0.1:15672
默认账号：guest 密码：guest
