在 Ubuntu 上安装 OpenSearch 可以通过官方提供的 Debian 包 或 Docker 来进行。下面我给你一个详细、可直接操作的步骤（以 Ubuntu 20.04/22.04 为例）
1.安装 Java（OpenSearch 需要 Java 17+）
OpenSearch 自带 OpenJDK 17，但如果你想用系统 Java 也可以：
sudo apt update
sudo apt install -y openjdk-17-jdk
java -version
确保输出类似：
openjdk version "17.x.x"
2️.下载并安装 OpenSearch Debian 包
2.1 下载 OpenSearch
到 OpenSearch 官方下载页面
选择 Debian .deb 包：
wget https://artifacts.opensearch.org/releases/bundle/opensearch/2.9.0/opensearch-2.9.0-linux-x64.deb
注意：版本号可以根据你需要选择最新的稳定版本。
2.2 安装包
sudo dpkg -i opensearch-2.9.0-linux-x64.deb
3.配置 OpenSearch
OpenSearch 配置文件在：/etc/opensearch/opensearch.yml
常用配置：
cluster.name: my-opensearch-cluster
node.name: node-1
network.host: 0.0.0.0 # 允许外部访问
http.port: 9200
discovery.type: single-node # 单节点模式
⚠️ 如果用于生产环境，需要开启安全认证（用户名/密码）。
下面是开启https 证书
plugins.security.ssl.transport.pemcert_filepath: esnode.pem
plugins.security.ssl.transport.pemkey_filepath: esnode-key.pem
plugins.security.ssl.transport.pemtrustedcas_filepath: root-ca.pem
plugins.security.ssl.transport.enforce_hostname_verification: false
plugins.security.ssl.http.enabled: true
plugins.security.ssl.http.pemcert_filepath: esnode.pem
plugins.security.ssl.http.pemkey_filepath: esnode-key.pem
plugins.security.ssl.http.pemtrustedcas_filepath: root-ca.pem
plugins.security.allow_unsafe_democertificates: true
plugins.security.allow_default_init_securityindex: true
4.启动 OpenSearch
sudo systemctl daemon-reload
sudo systemctl enable opensearch
sudo systemctl start opensearch
检查状态：
sudo systemctl status opensearch
5.测试 OpenSearch 在本机执行：
# 默认访问：
curl -k -u admin:admin https://127.0.0.1:9200/
返回结果：
{
"name" : "node-1",
"cluster_name" : "my-application",
"cluster_uuid" : "zBFxptErSquErr0OajHpFA",
"version" : {
"distribution" : "opensearch",
"number" : "2.9.0",
"build_type" : "deb",
"build_hash" : "1164221ee2b8ba3560f0ff492309867beea28433",
"build_date" : "2023-07-18T21:22:32.045158091Z",
"build_snapshot" : false,
"lucene_version" : "9.7.0",
"minimum_wire_compatibility_version" : "7.10.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "The OpenSearch Project: https://opensearch.org/"
}
}
6（可选）安装 OpenSearch Dashboards
OpenSearch Dashboards 提供可视化界面：
wget https://artifacts.opensearch.org/releases/bundle/opensearch-dashboards/2.9.0/opensearch-dashboards-2.9.0-linux-x64.deb
sudo dpkg -i opensearch-dashboards-2.9.0-linux-x64.deb
sudo systemctl enable opensearch-dashboards
sudo systemctl start opensearch-dashboards
