elasticsearch8安装部署

以下是elasticsearch8的安装部署步骤：

1. 下载elasticsearch8压缩包并解压缩

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.4.0-linux-x86_64.tar.gz
tar -zxvf elasticsearch-8.4.0-linux-x86_64.tar.gz

2. 进入elasticsearch目录并修改配置文件

cd elasticsearch-8.4.0/config
vi elasticsearch.yml

在elasticsearch.yml文件中修改以下配置：

cluster.name: my-application # 集群名称
node.name: node-1 # 节点名称
path.data: /path/to/data # 数据存储路径
path.logs: /path/to/logs # 日志存储路径
network.host: 0.0.0.0 # 绑定IP地址
http.port: 9200 # HTTP端口

3. 启动elasticsearch

cd ..
bin/elasticsearch

4. 验证elasticsearch是否启动成功

curl http://localhost:9200/

如果返回以下信息，则表示elasticsearch已经成功启动：

{
  "name" : "node-1",
  "cluster_name" : "my-application",
  "cluster_uuid" : "xxxxxxxxxxxxxxxxxxxx",
  "version" : {
    "number" : "8.4.0",
