摘要
Erlang是一种通用的面向并发的编程语言，它由瑞典电信设备制造商爱立信所辖的CS-Lab开发，目的是创造一种可以应对大规模并发活动的编程语言和运行环境。
环境准备
系统环境
使用命令：uname -a 或者 uname -r，执行后如下：
安装编译依赖
yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto perl wget
下载
下载地址 : 官网下载
$ wget https://erlang.org/download/otp_src_25.1.tar.gz
解压
$ tar -xzvf otp_src_25.1.tar.gz
$ cd otp_src_25.1
$ ./configure --prefix=/usr/local/erlang
这里执行后 会出现一些警告信息：
root@test-vmware71:/usr/local/otp_src_25.1# ./configure --prefix=/usr/local/erlang

跳过继续执行！！！
编译与安装
make && make install
配置环境变量
$ vim /etc/profile
在后面追加内容：
export ERLANG_HOME=/usr/local/erlang
export PATH=$ERLANG_HOME/bin:$PATH
然后执行刷新配置
$ source /etc/profile
验证Erlang
erl -version
