详见 Docker 安装 Elasticsearch、Kibana
或者 使用 docker compose 安装
[root@localhost ~]# docker-compose version
bash: docker-compose: 未找到命令...
docker compose 下载地址:https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-linux-x86_64
将 docker-compose-Linux-x86_64 传到 /usr/local/bin 目录下,并改名为 docker-compose
[root@localhost ~]# chmod +x /usr/local/bin/docker-compose
[root@localhost ~]# docker-compose version
Docker Compose version v2.16.0
在目录 /opt/elasticsearch (目录自定义)下创建 docker-compose.yml 文件内容如下
version: "7.9.3"
services:
elasticsearch:
image: elasticsearch:7.9.3
restart: always
container_name: elasticsearch
ports:
- 9200:9200
volumes:
- /opt/elasticsearch/logs:/usr/share/elasticsearch/logs
kibana:
image: kibana:7.9.3
restart: always
container_name: kibana
ports:
- 5601:5601
environment:
- elasticsearch url=http://172.16.3.88:9200
- I18N_LOCALE=zh-CN
depends_on:
- elasticsearch
执行命令
[root@localhost ~]# cd /opt/elasticsearch
[root@localhost elasticsearch]# pwd
/opt/elasticsearch
#安装
[root@localhost elasticsearch]# docker-compose up -d

#查看日志
[root@localhost elasticsearch]# docker-compose logs -f
ES 默认分词器,对汉字的分词不太友好
找到对应的 Elasticsearch 版本,这里用的:7.9.3,将地址复制到讯雷里下,直接下的话下不动
https://elasticsearch.cn/download/
先把zip下载下来。放到任意一台服务器(直接github上下载多数会失败)

ES 是一个使用Java语言并且基于Lucene编写的搜索引擎框架,他提供了分布式的全文搜索功能,提供了一个统一的基于Restful风格的WEB接口,官方客户端也对多种语言都提供了相应的API。
