安装
安装erlang
- 查看是否存在旧erlang版本
erl -version - 若版本低于（version 11.2.2），卸载erlang
yum -y remove erlang-* - 安装erlang所依赖工具
yum -y install make gcc gcc-c kernel-devel m4 ncurses-devel openssl-devel - 安装 socat
erlang内存管理依赖socat
yum install -y socat - 安装 signing-key，用于和 yum更新源通信
rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc - 更新源
vi /etc/yum.repos.d/rabbitmq_erlang.repo将对应的内容拷贝到文件里面，参考链接：https://github.com/rabbitmq/erlang-rpm 使用 Erlang 23.3 配置 复制除 begin end 分割线外的中间内容
