简单的安装
参考：https://blog.csdn.net/smilehappiness/article/details/118466378
官网：https://www.elastic.co/guide/en/elasticsearch/reference/current/targz.html
- 下载：https://www.elastic.co/cn/downloads/elasticsearch
- 解压：tar -zxvf elasticsearch-8.17.3-linux-x86_64.tar.gz
- 设置ES_HOME并添加path路径ES_HOME/bin
- 运行：
elasticsearch
有可能用了非es内部的jdk报错。
配置jdk路径（避免ES调linux事先配置的jdk）
export JAVA_HOME=/data1/ztshao/programs/elasticsearch-8.17.3/jdk
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tool.jar
初次启动会初始化一个密码，存下来。
bash设置密码export ELASTIC_PASSWORD="your_password"
- 查看运行情况的运行方式：
elasticsearch -E xpack.security.enabled=false。注意要加后面的enabled=false。不然返回都是空的。
import requests
# 定义要访问的URL
url= "http://127.0.0.1:9200/"
try:response = requests.get(url)# 输出服务器返回的内容print("Response:")print(response.text)
except requests.exceptions.RequestException as e:# 如果请求失败，输出错误信息print("Error:", e)
输出内容：
Response:
<Response [200]>
{"name" : "crowley.nju.edu.cn","cluster_name" : "elasticsearch","cluster_uuid" : "9fN7znHVToW9PmKqGh3ITg","version" : {"number" : "8.17.3","build_flavor" : "default","build_type" : "tar","build_hash" : "a091390de485bd4b127884f7e565c0cad59b10d2","build_date" : "2025-02-28T10:07:26.089129809Z","build_snapshot" : false,"lucene_version" : "9.12.0","minimum_wire_compatibility_version" : "7.17.0","minimum_index_compatibility_version" : "7.0.0"},"tagline" : "You Know, for Search"
}
输出这个内容说明安装成功了。
- 远程看浏览器：我这里直接通过ssh转了9200和8000的接口
ssh -R 9200:localhost:9200 -N ztshao@114.212.85.127
ssh -R 8000:localhost:8000 -N ztshao@114.212.85.127
- 远程访问，修改配置：config/elasticsearch.yml。添加配置
network.host: 0.0.0.0允许远程访问
报错参考：https://blog.csdn.net/Leon_Jinhai_Sun/article/details/126673674
配置密码在shell里：
export ELASTIC_PASSWORD="your_password"
