于 2025-08-02 13:38:22 首次发布

# Ubuntu/Debian
sudo apt update
sudo apt install openjdk-11-jdk

# CentOS/RHEL
sudo yum install java-11-openjdk-devel

# 验证安装
java -version

创建目录/usr/share/keyrings/

sudo mkdir -p /usr/share/keyrings/

然后重新执行导入 GPG 密钥的命令：

# 导入 Elasticsearch 公钥
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elasticsearch-keyring.gpg

sudo tee /etc/yum.repos.d/elasticsearch.repo <<EOF
[elasticsearch]
name=Elasticsearch repository for 8.x packages
baseurl=https://artifacts.elastic.co/packages/8.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md
EOF

然后安装 Elasticsearch：

sudo yum install elasticsearch

安装完成后，启动并设置开机自启：

sudo systemctl start elasticsearch
sudo systemctl enable elasticsearch

Elasticsearch 8.x 首次启动时会自动生成 elastic 用户的初始密码，可通过以下命令重置（如果之前没找到）：

sudo /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic -i

curl -k -u elastic:刚才获取的密码 https://localhost:9200

成功响应示例
如果配置正确，会返回类似以下的 JSON 信息：

{
  "name" : "localhost.localdomain",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "xxxxxxxxxxxxxxxxxxxx",
  "version" : {
    "number" : "8.10.4",
    "build_flavor" : "default",
    "build_type" : "rpm",
    ...
  },
  "tagline" : "You Know, for Search"
}
