1、 安装Elixir之前必须要先安装Erlang

参考1：【CentOS 7 系统安装 Erlang/OTP 22.0】进行安装

参考2：【Centos 用Kerl安装及管理Erlang】进行安装

2、安装Elixir

$ git clone https://github.com/elixir-lang/elixir.git
$ cd elixir
$ make clean test

输出示例：

如果测试通过，则表示编译安装完成。

3、配置环境变量

接下来将Elixir的bin路径添加到PATH环境变量中，否则Elixir将无法正常工作。

方法一（暂时生效）

现在运行以下命令：

 export PATH="$PATH:/home/summergao/elixir/bin"

在这里，我把Elixir安装在了 /home/summergao/elixir 。你必须将此路径替换为你实际的Elixir安装路径。

方法二（只对当前登陆用户生效，永久生效）

vim ~/.bash_profile

默认如下：

PATH=$PATH:$HOME/bin

添加后：

PATH=$PATH:$HOME/bin:$PATH:/home/summergao/elixir/bin

接下来执行 source ~/.bash_profile 使其立即生效或者 reboot 重启生效

source ~/.bash_profile

方法三（对所有系统用户生效，永久生效）

vim /etc/profile

在 export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL 下面添加

export ELIXIR_HOME=/home/summergao/elixir/
export PATH=$PATH:$ELIXIR_HOME/bin

接下来执行 source /etc/profile 使其立即生效或者 reboot 重启生效

source /etc/profile

验证Elixir

iex

如果你看到Elixir shell，则表示安装成功！

同样，要关闭Elixir shell，只需按两次Ctrl-C。

查看Elixir版本：

elixir --version
