--------------------

# 1 部署elasticsearch #

1、创建elasticsearch数据存储目录

rm -rf /mydata/elasticsearch
    mkdir -p /mydata/elasticsearch/config /mydata/elasticsearch/data /mydata/elasticsearch/plugins/ik
    echo "http.host: 0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch.yml
    ### 保证权限（有目录映射可能会出现非root用户没用访问权限）
    chmod -R 777 /mydata/elasticsearch/

2、下载IK安装分词器

### 下载
    wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.4.2/elasticsearch-analysis-ik-7.4.2.zip
    ### 解压
    unzip elasticsearch-analysis-ik-7.4.2.zip -d /mydata/elasticsearch/plugins/ik/
    ### 删除zip文件
    rm -rf elasticsearch-analysis-ik-7.4.2.zip

3、启动elasticsearch

docker run \
    --name es742 \
    -p 9200:9200 \
    -p 9300:9300 \
    -e "discovery.type=single-node" \
    -e ES_JAVA_OPTS="-Xms512m -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

4、查看es是否启动

[root@localhost ~]# curl http://127.0.0.1:9200/
    {
      "name" : "db03fad7d132",
      "cluster_name" : "elasticsearch",
      "cluster_uuid" : "5SfOiSX-SJmxIFAuuv9Rwg",
      "version" : {
        "number" : "7.4.2",
        "build_flavor" : "default",
        "build_type" : "docker",
        "build_hash" : "2f90bbf7b93631e52bafb59b3b049cb44ec25e96",
        "build_date" : "2019-10-28T20:40:44.881551Z",
        "build_snapshot" : false,
        "lucene_version" : "8.2.0",
        "minimum_wire_compatibility_version" : "6.8.0",
        "minimum_index_compatibility_version" : "6.0.0-beta1"
      },
      "tagline" : "You Know, for Search"
    }

--------------------

# 2 部署kibana #

docker run \
    --name kb742 \
    -p 5601:5601 \
    -e ELASTICSEARCH_HOSTS=http://10.4.42.21:9200 \
    -e "I18N_LOCALE=zh-CN" \
    -d kibana:7.4.2

### kibana上测试分词器
    POST _analyze
    {
        "analyzer": "ik_smart",
        "text": "我是中国人"
    }

--------------------

# 3 访问 #

elasticsearch：[http://10.4.42.21:9200/][http_10.4.42.21_9200]，kiban：[http://10.4.42.21:5601/app/kibana][http_10.4.42.21_5601_app_kibana]

--------------------

# 4 测试 #

1、插入数据

### 创建book索引
    PUT /book/
    {
      "settings": {
        "number_of_shards": 1,
        "number_of_replicas": 0
      },
      "mappings": {
        "properties": {
          "name":{
            "type": "text",
            "analyzer": "ik_max_word",
            "search_analyzer": "ik_smart"
          },
          "description":{
            "type": "text",
            "analyzer": "ik_max_word",
            "search_analyzer": "ik_smart"
          },
          "studymodel":{
            "type": "keyword"
          },
          "price":{
            "type": "double"
          },
          "timestamp": {
             "type": "date",
             "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
          },
          "pic":{
            "type":"text",
            "index":false
          }
        }
      }
    }

    {
      "query": {
        "match": {
          "studymodel": "201001"
        }
      }
    }'
