RabbitMQ是流行的开源消息队列系统，是AMQP（Advanced Message Queuing Protocol高级消息队列协议）的标准实现，用erlang语言开发。RabbitMQ据说具有良好的性能和时效性，同时还能够非常好的支持集群和负载部署，非常适合在较大规模的分布式系统中使用，具体特性还在验证中，待检验。由于项目需要，安装并配置了RabbitMQ，服务器操作系统是CentOS7，服务器是阿里云主机。具体步骤如下：
安装依赖文件：
yum install gcc glibc-devel make ncurses-devel openssl-devel xmlto
1.Erlang安装配置
下载安装包，地址http://www.erlang.org/downloads，我选择的是otp_src_18.3.tar.gz。
然后解压文件：
[root@iZ25e3bt9a6Z rabbitmq]# tar -xzvf otp_src_18.3.tar.gz [root@iZ25e3bt9a6Z rabbitmq]# cd otp_src_18.3/
配置安装路径编译代码：
[root@iZ25e3bt9a6Z otp_src_18.3]# ./configure --prefix=/opt/erlang
执行编译结果：
[root@iZ25e3bt9a6Z otp_src_18.3]# make && make install
完成后进入/opt/erlang查看执行结果
[root@iZ25e3bt9a6Z rabbitmq]# cd /opt/erlang/ [root@iZ25e3bt9a6Z erlang]# erl Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] Eshell V7.3 (abort with ^G) 1>
当出现以上信息时表示安装完成。然后输入’halt().’退出即可。
然后在配置Erlang环境变量,vi /etc/profile文件，增加下面的环境变量:
#set erlang environment
export PATH=$PATH:/opt/erlang/bin
source /etc/profile使得文件生效
在安装Erlang过程中，可能会遇到以下问题，一般都是因为系统中缺少相应的包引起的，缺少什么包直接yum安装即可。
2.下载安装RabbitMq
[root@iZ25e3bt9a6Z rabbitmq]# weget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.1/rabbitmq-server-generic-unix-3.6.1.tar.xz
解压文件
[root@iZ25e3bt9a6Z rabbitmq]# xz -d rabbitmq-server-generic-unix-3.6.1.tar.xz [root@iZ25e3bt9a6Z rabbitmq]# tar -xvf rabbitmq-server-generic-unix-3.6.1.tar -C /opt
解压后进入文件夹/opt发现多了个文件夹rabbitmq-server-generic-unix-3.6.1 ，重命名为rabbitmq以便记忆。
然后在配置rabbitmq环境变量,vi /etc/profile文件，增加下面的环境变量:
#set rabbitmq environment export PATH=$PATH:/opt/rabbitmq/sbin
source /etc/profile使得文件生效
3.RabbitMQ服务启动关闭
以上就已经完成了RabbitMq的安装，怎么启动服务呢？
启动服务：
[root@iZ25e3bt9a6Z rabbitmq]# cd sbin/ [root@iZ25e3bt9a6Z sbin]# ./rabbitmq-server -detached
查看服务状态：
[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl status
Status of node rabbit@iZ25e3bt9a6Z ...

{uptime,412681},
{kernel,{net_ticktime,60}}]
关闭服务：
[root@iZ25e3bt9a6Z sbin]# ./rabbitmqctl stop Stopping and halting node rabbit@iZ25e3bt9a6Z ...
4. 配置网页插件
首先创建目录，否则可能报错：
mkdir /etc/rabbitmq
然后启用插件：
./rabbitmq-plugins enable rabbitmq_management
配置linux 端口 15672 网页管理 5672 AMQP端口
然后访问http://localhost:15672即可
默认用户guest 密码guest
5. 远程访问配置
默认网页是不允许访问的，需要增加一个用户修改一下权限，代码如下：
添加用户:rabbitmqctl add_user hxb hxb
添加权限:rabbitmqctl set_permissions -p "/" hxb ".*" ".*" ".*"
修改用户角色rabbitmqctl set_user_tags hxb administrator
然后就可以远程访问了，然后可直接配置用户权限等信息。
6. rabbitmq常用命令
