问题描述

物理机：MAC
安装途径：homebrew

问题出现的环境背景及自己尝试过哪些方法

成功启动第一个节点后，想要启动第二个节点，复制了elasticsearch文件夹，并对配置文件进行了修改，进入node2目录后，运行./bin/elasticsearch，启动过程仍然是node1，然后因为node1已存在报错

目录结构：

elasticsearch_node1
elasticsearch_node2

不知道是不是和homebrew安装有关？
我没有在.bash_profile或/etc/profile中配置elasticsearch路径，但是homebrew安装完成后，直接可以在命令行使用elasticsearch启动，不知道是否有默认环境变量？导致只能启动一个es节点？

刚开始接触elasticsearch，有很多不懂。如果您曾经在单机上搭建过elasticsearch多节点，请看看这个问题，万分感谢。

如果还需要更多信息，请在问题下留言。
