为什么使用 OpenSearch?

OpenSearch 是一个高效维护的套件，通常被用于下面的一些情况：

日志分析（Log analytics）
实时应用监控（Real-time application monitoring）
点击流分析（Clickstream analytics）
后台查询（Search backend）

组件	目的
OpenSearch	数据存储和搜索引擎
OpenSearch 面板（OpenSearch Dashboards）	搜索前台可视化界面
安全（Security）	针对集群的授权和访问控制
报警（Alerting）	当你的数据达到某个阈值后获得通知
SQL	使用 SQL 或者管道处理语言（piped processing language）来对你的数据进查询
索引状态管理（Index State Management）	自动化的索引操作
KNN	在你的矢量数据中找到 “nearest neighbors”
性能分析器（Performance Analyzer）	监控和优化你的集群
异常侦测（Anomaly detection）	识别非典型数据然后自动收到通知
异步查询（Asynchronous search）	在你的后台搜运行查询请求
跨集群复制（Cross-cluster replication）	在多个 OpenSearch 集群之间对你的数据进行复制

绝大多数的 OpenSearch 插件都有相对应的 OpenSearch 面板插件，能够提供方便、统一的用户界面。

Docker quickstart

Docker {: .label .label-green }

Install and start Docker Desktop.

Run the following commands:

docker pull opensearchproject/opensearch:{{site.opensearch_version}}
docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:{{site.opensearch_version}}

In a new terminal session, run:

curl -XGET --insecure -u 'admin:admin' 'https://localhost:9200'

Create your first index.

curl -XPUT --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index'

Add some data to your newly created index.

curl -XPUT --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1' -H 'Content-Type: application/json' -d '{"Description": "To be or not to be, that is the question."}'

Retrieve the data to see that it was added properly.

curl -XGET --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1'

After verifying that the data is correct, delete the document.

curl -XDELETE --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1'

Finally, delete the index.

curl -XDELETE --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/'

To learn more, see Docker image and Docker security configuration.

Installation

For more comprehensive installation instructions for other download types, such as tarballs, see these pages:

The secure path forward

OpenSearch includes a demo configuration so that you can get up and running quickly, but before using OpenSearch in a production environment, you must configure the security plugin manually: your own certificates, your own authentication method, your own users, and your own passwords.

Looking for the Javadoc?

See opensearch.org/javadocs/.
