RabbitMQ的安装

安装依赖

yum install epel-release
yum install unixODBC unixODBC-devel wxBase wxGTK SDL wxGTK-gl make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel

配置erlang安装源
在/etc/yum.repos.d 下新建一个erlang-solutions.repo文件，vim /etc/yum.repos.d/erlang-solutions.repo, 内容如下：

[erlang-solutions]
name=Centos $releasever - $basearch - Erlang Solutions
baseurl=http://binaries.erlang-solutions.com/rpm/centos/$releasever/$basearch
gpgcheck=1
gpgkey=http://binaries.erlang-solutions.com/debian/erlang_solutions.asc
enabled=1

导入Key：

rpm --import http://binaries.erlang-solutions.com/debian/erlang_solutions.asc

安装erlang（这一步可有可无，因为使用yum install方式安装rabbitmq-server-3.7.18-1.el7.noarch.rpm这个包可以自动解决依赖）

yum install erlang --enablerepo=erlang-solutions

安装rabbitmq

yum install rabbitmq-server-3.7.18-1.el7.noarch.rpm
