elasticsearch-7.5.1 单台服务器部署多个节点

1、将安装好的elasticsearch-7.5.1文件夹在复制一份

$ cp -R elasticsearch-7.5.1 elasticsearch-7.5.1-node2 #复制文件件

$ chown elasticsearch:elasticsearch elasticsearch-7.5.1-node2 #修改所属用户和组

2、修改配置文件

$ cd elasticsearch-7.5.1-node2
$ vim config/elasticsearch.yml
#集群名称，和elasticsearch-7.5.1中保持一致
cluster.name: share-es
#将node-1修改为node-2
node.name: node-2

3、分别在elasticsearch-7.5.1和elasticsearch-7.5.1-node2中启动节点

$ ./bin/elasticsearch

4、查看是否配置成功

#浏览器访问：http://ip:9200/_cluster/health?pretty 或者 http://ip:9201/_cluster/health?pretty
