摘要： 今天教大家利用镜像快熟部署使用RabbitMQ。RabbitMQ是一个开源的AMQP实现，服务器端用Erlang语言编写，支持多种客户端，用于在分布式系统中存储转发消息，在易用性、扩展性、高可用性等方面表现不俗。
RabbitMQ是一个开源的AMQP实现，服务器端用Erlang语言编写，支持多种客户端，如：Python、Ruby、.NET、Java、JMS、C、PHP、ActionScript、XMPP、STOMP等，支持AJAX。用于在分布式系统中存储转发消息，在易用性、扩展性、高可用性等方面表现不俗。
部署方式
在阿里云服务器下部署 RabbitMQ提供两种部署方式：
- RabbitMQ镜像部署
- 手动部署（源码编译安装/YUM安装）
一般推荐镜像部署适合新手使用更加快捷方便，安装包部署以及手动部署适合对Linux命令有基本了解的用户，可以满足用户个性化部署的要求。本教程主要介绍镜像和手工部署的方式。
镜像部署
1. 单击 JAVA环境（CentOS7.2 Nginx Tomcat8 JDK）进入镜像详情页。
2. 单击 **立即购买**，按提示步骤购买 ECS 实例。
3. 登录 ECS 管理控制台：https://ecs.console.aliyun.com/#/home
4. 在左边导航栏里，单击 **实例**，进入 ECS 实例列表页。
5. 选择所购 ECS 实例所在的地域，并找到所购 ECS 实例，在 **IP 地址** 列获取该实例的公网 IP 地址。
6. 在浏览器地址栏中输入公网 IP 地址，下载操作文档。
8. 使用winscp工具将Java代码放入/data/wwwroot/default中。
9. 默认tomcat是以一般www用户运行，将网站代码权限改为www，执行下面命令：
chown -R www.www /data/wwwroot
10. 重启tomcat
11. 在浏览器地址栏中输入公网 IP 地址，验证。
手工部署
系统平台：CentOS 7.3
rabbitmq版本：rabbitmq-server -3.6.9
erlang版本：erlang19.3
JDK版本：JDK1.8.0_121
- 前提准备
创建一般用户rabbitmq，运行rabbitmq
useradd rabbitmq设置Linux主机名
centos7修改/etc/hostname，centos6修改/etc/sysconfig/network，下面以centos7为例
echo rabbit1 > /etc/hostname
hostname rabbit1
exit #退出重新登录
yum -y install make gcc gcc-c++ m4 ncurses-devel openssl-devel unixODBC-devel
- 源代码下载
wget http://erlang.org/download/otp_src_19.3.tar.gz
wget https://www.rabbitmq.com/releases/rabbitmq-server/v3.6.9/rabbitmq-server-generic-unix-3.6.9.tar.xz- 安装Erlang
tar xzf otp_src_19.3.tar.gz #解压
cd otp_src_19.3
./configure --prefix=/usr/local/erlang --enable-shared-zlib --with-ssl --enable-threads --enable-smp-support --enable-kernel-poll --enable-hipe --without-javac
make && make install- 解压RabbitMQ
