elasticsearch: 指定索引数据的保存目录

一，查看节点的fs得到索引数据的保存目录

说明：

修改索引数据的保存目录，通常是因为要把数据单独保存到服务器专用的数据盘，
方便扩展\管理\备份等

http://localhost:9200/_nodes/stats/fs

[root@lhdpc elasticsearch]# curl -X GET "localhost:9200/_nodes/stats/fs?pretty"

二，从配置文件中修改索引数据的保存目录

[root@lhdpc elasticsearch-8.14.2]# vi config/elasticsearch.yml

path.data: /data/data/elasticsearch/data
path.logs: /data/data/elasticsearch/logs

2，启动es

liuhongdi@lhdpc:/usr/local/soft/elasticsearch-8.14.2$ /usr/local/soft/elasticsearch-8.14.2/bin/elasticsearch -d

liuhongdi@lhdpc:/usr/local/soft/elasticsearch-8.14.2$ ls /data/data/elasticsearch/data/
node.lock nodes snapshot_cache _state

liuhongdi@lhdpc:/usr/local/soft/elasticsearch-8.14.2$ ls /data/data/elasticsearch/logs/
