   sudo apt install openjdk-8-jdk

2. 安装Elasticsearch：
- 添加Elasticsearch的APT源：

     wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
     sudo apt-get install apt-transport-https
     echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-7.x.list

- 安装Elasticsearch：

     sudo apt update
     sudo apt install elasticsearch

- 启动Elasticsearch服务：

     sudo systemctl start elasticsearch
