1、安装elasticsearch

下载镜像文件

docker pull elasticsearch:7.4.2
docker pull kibana:7.4.2

本地创建两个文件

mkdir -p /mydata/elasticsearch/config    //配置文件信息挂载到这个文件夹下
mkdir -p /mydata/elasticsearch/data      //

修改配置文件

echo "http.host: 0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch.yml

给文件夹添加权限

chmod -R 777 /mydata/elasticsearch/

运行镜像

docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms64m -Xmx512m" \
-v /mydata/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
-v /mydata/elasticsearch/data:/usr/share/elasticsearch/data \
-v /mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-d elasticsearch:7.4.2

设置开机自启

docker update elasticsearch --restart=always

启动起来后查看该容器的日志

docker logs elasticsearch
docker logs [容器id]
docker logs [容器id前三位]

测试访问地址：192.168.20.140:9200

访问不到可以尝试把防火墙关掉

systemctl enable firewalld

通过postman访问

2、安装Kibana

下载镜像文件

docker pull kibana:7.4.2

运行镜像

docker run --name kibana -e ELASTICSEARCH_HOSTS=http://192.168.20.140:9200 -p 5601:5601 \
-d kibana:7.4.2

// 注意如果用的是云服务器，并且es和kibana在一台机器，则使用如下命令找到ip地址
docker inspect elasticsearch | grep IPAddress
// 并把ip地址放在host后面
// 一般是172.17.0.3

// http://192.168.91.100:9200 一定改为自己虚拟机的地址

设置开机自启

docker update kibana --restart=always

测试地址：192.168.20.140:5601

初始化es数据

PUT gulimall_product
{
  "mappings":{
    "properties":{
      "skuId":{
        "type":"long"
      },
       "spuId":{
        "type":"keyword"
      },
       "skuTitle":{
        "type":"text",
        "analyzer": "ik_smart"
      },
       "skuPrice":{
        "type":"keyword"
      },
       "skuImg":{
        "type":"text",
        "analyzer": "ik_smart"
      },
       "saleCount":{
        "type":"long"
      },
       "hasStock":{
        "type":"boolean"
      },
      "hotScore":{
        "type":"long"
      },
      "brandId":{
        "type":"long"
      },
      "catelogId":{
        "type":"long"
      },
      "brandName":{
        "type":"keyword",
        "index": false,
        "doc_values": false
      },
      "brandImg":{
        "type":"keyword",
         "index": false,
        "doc_values": false
      },
      "catalogName":{
        "type":"keyword",
         "index": false,
         "doc_values": false
      },
      "attrs":{
        "type":"nested",
        "properties": {
          "attrId":{
            "type":"long"
          },
          "attrName":{
            "type":"keyword",
            "index":false,
            "doc_values":false
          },
          "attrValue": {
            "type":"keyword"
          }
        }
      }
    }
  }
}

3、初步检索

3.1、_cat

GET /_cat/nodes：查看所有节点  实例：http://192.168.20.140:9200/_cat/nodes
GET /_cat/health：查看 es 健康状况  http://192.168.20.140:9200/_cat/health
GET /_cat/master：查看主节点 http://192.168.20.140:9200/_cat/master
GET /_cat/indices：查看所有索引  http://192.168.20.140:9200/_cat/indices
