搭建部署步骤

下载Elasticsearch

curl -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.16.2-linux-x86_64.tar.gz

解压

tar -zxvf elasticsearch-7.16.2-linux-x86_64.tar.gz 

修改配置让外部能访问

# config目录下执行
vim elasticsearch.yml 
# 加入下方配置 (默认只能本地访问,加入下方配置外部即可访问)
network.host: 0.0.0.0

启动ElasticSearch

# 可以加上 -d 参数表示后台运行
# ./bin/elasticsearch -d
./bin/elasticsearch

测试是否启动成功

发送一个 HTTP 请求到 localhost 的端口9200来测试 Elasticsearch 节点是否正在运行

http://192.168.6.130:9200/

响应如下内容表示启动成功
