第一步：安裝erlang（最精簡版本erlang安裝，適用於rabbitmq）
1.檢查是否安裝過
rpm -qa erlang
rpm -e erlang-xxxxxx
卸載完成后 按照官方步驟安裝精簡版rabbitmq-erlang
https://github.com/rabbitmq/erlang-rp
2.在/etc/yum.repos.d/ 下創建rabbitmq-erlang.repo，添加如下內容
[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq-erlang/rpm/erlang/22/el/6
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1
3.yum install erlang
第二步：安裝rabbitmq-server
1. 以root用戶執行 rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
2. 在/etc/yum.repos.d/ 下創建rabbitmq.repo，添加如下內容
[bintray-rabbitmq-server] name=bintray-rabbitmq-rpm baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.7.x/el/7/ gpgcheck=0 repo_gpgcheck=0 enabled=1
3.yum install rabbitmq-server
4. 1）開啟延時隊列（非死信隊列方式）安裝插件： https://www.rabbitmq.com/community-plugins.html 下載rabbitmq_delayed_message_exchange 注意mq版本
