堡垒机内使用linux命令安装Elasticsearch集群客户端命令

在堡垒机（通常用于远程管理服务器）上使用Linux命令安装Elasticsearch集群客户端，你可以按照以下步骤操作，假设已经通过SSH连接到堡垒机：

1. **更新包列表并安装必要的依赖**:

   sudo apt-get update
   sudo apt-get install -y wget curl gnupg2

2. **添加Elasticsearch官方GPG密钥**:

   echo "deb http://packages.elastic.co/elasticsearch/7.x/debian stable main" | sudo tee /etc/apt/sources.list.d/elasticsearch.list
   curl -L https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

3. **刷新包数据库并安装elasticsearch-curator客户端** (如果需要curator):

   sudo apt-get update
   sudo apt-get install -y elasticsearch-curator

4. **直接安装elasticsearch-head（可视化工具）** (如果不需要curator):

   wget -qO - https://packages.elastic.co/elasticsearch/elasticsearch/elasticsearch-7.x.x.deb.gpg | sudo apt-key add -
   echo "deb https://packages.elastic.co/elasticsearch/elasticsearch/7.x/debian stable main" | sudo tee /etc/apt/sources.list.d/elasticsearch.list
   sudo apt-get update
   sudo apt-get install -y kibana

5. **启动和启用服务**:

   sudo service elasticsearch start
   sudo systemctl enable elasticsearch

6. **验证安装**:

   curl -X GET "http://localhost:9200/"

这将显示Elasticsearch欢迎信息，表明安装成功。
