篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CentOS7下RabbitMQ服务安装配置相关的知识，希望对你有一定的参考价值。

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。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：

[[email protected] rabbitmq]# tar -xzvf otp_src_18.3.tar.gz
[[email protected] rabbitmq]# cd otp_src_18.3/

　　配置安装路径编译代码：

[[email protected] otp_src_18.3]# ./configure --prefix=/opt/erlang

　　执行编译结果：

[[email protected] otp_src_18.3]# make && make install

　　完成后进入/opt/erlang查看执行结果

[[email protected] rabbitmq]# cd /opt/erlang/
[[email protected] 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

[[email protected] 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

[[email protected] rabbitmq]# xz -d rabbitmq-server-generic-unix-3.6.1.tar.xz
[[email protected] 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：

[[email protected] rabbitmq]# cd sbin/
[[email protected] sbin]# ./rabbitmq-server -detached

　　查看服务状态：

[[email protected] sbin]# ./rabbitmqctl status
