tar -zxvf elasticsearch-8.19.3-linux-x86_64.tar.gz

或指定解壓目錄

tar -xzf elasticsearch-8.19.3-linux-x86_64.tar.gz -C /opt/elasticsearch

創建data目錄(存放數據)

mkdir?/opt/elasticsearch-8.19.3/data

logs目錄:elasticsearch-8.19.3中自帶了logs目錄,直接使用

(es必須使用非root用戶啟動)創建啟動es的用戶

useradd esuser

修改目錄權限

chown -R esuser?/opt/elasticsearch-8.19.3

修改配置

修改jvm內存(設置大小自己根據機器估算)
/config/jvm.options

## IMPORTANT: JVM heap size
-Xms265m
-Xmx4g

修改es設置
/config/elasticsearch.yml

cluster.name: my-application
path.data: /opt/elasticsearch-8.19.3/data
path.logs: /opt/elasticsearch-8.19.3/logs
network.host: 0.0.0.0
http.port: 9200
# 關閉生產環境檢查（僅用于本地測試！）

配置系統sevice服務

/etc/systemd/system/中創建文件elasticsearch.service

ExecStart=/opt/elasticsearch-8.19.3/bin/elasticsearch
#啟動失敗后自動重啟
#Restart=always
User=esuser
Group=esuser[Install]
WantedBy=multi-user.target

啟動sevice服務

systemctl start?elasticsearch

查看日志

tail -f?/opt/elasticsearch-8.19.3/logs/my-application.log

設置密碼

es8默認啟用了安全策略,啟動后就有密碼了在日志中可以查找
啟動后自定義密碼

./bin/elasticsearch-reset-password -u elastic -i

驗證是否可用
瀏覽器訪問https://yourip:9200(注意用https)輸入密碼
或

curl -k -u 'elastic:yourpassword' https://localhost:9200/
