[大数据]docker 安装elasticsearch kibana ik分词器

一、elasticsearch kibana
1、安装镜像

docker pull elasticsearch:7.4.2
docker pull kibana:7.4.2

2、创建文件夹 并授予权限

mkdir -p /mydata/elasticsearch/data
mkdir -p /mydata/elasticsearch/config
chmod 777 /mydata/elasticsearch/config/
chmod 777 /mydata/elasticsearch/data/

3、启动 -d 后台运行 -p端口映射 -e 环境变量配置

 docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms128m -Xmx512m"  -v /mydata/elasticsearch/data:/usr/share/elasticsearch/data -v/mydata/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.4.2

4、解决问题

Error response from daemon: Conflict. The container name "/kibana" is already in use by container "e7670a321f758a36d13963cd092aad30132be59d3a7f083d8fbbfc0c27d792ef". You have to remove (or rename) that container to be able to reuse that name.

docker ps -a 删除容器
之后再启动

4.2 kibana启动不起来

解决es分配内网：

docker inspect elasticsearch  |grep IPAddress

使用es分配的内网启动kibana

docker run --name kibana -e ELASTICSEARCH_HOSTS=http://172.17.0.3:9200 -p 5601:5601 -d kibana:7.4.2

二、分词器
1、在/mydata/elasticsearch/plugins 目录下 下载ik分词压缩包

yum install wget
wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.4.2/elasticsearch-analysis-ik-7.4.2.zip

2、解压到ik文件夹下

yum install unzip 
unzip elasticsearch-analysis-ik-7.4.2.zip
删除zip
rm -rf *.zip

3、将解压的文件放在ik文件夹下
重新启动elasticsearch

安装分词器之前

POST _analyze
{
  "text": "北京冬奥会，加油！"
}

结果

{
  "tokens" : [
    {
      "token" : "北",
      "start_offset" : 0,
      "end_offset" : 1,
      "type" : "<IDEOGRAPHIC>",
      "position" : 0
    },
    {
      "token" : "京",
      "start_offset" : 1,
      "end_offset" : 2,
      "type" : "<IDEOGRAPHIC>",
      "position" : 1
    },
    {
      "token" : "冬",
      "start_offset" : 2,
      "end_offset" : 3,
      "type" : "<IDEOGRAPHIC>",
      "position" : 2
    },
    {
      "token" : "奥",
      "start_offset" : 3,
      "end_offset" : 4,
      "type" : "<IDEOGRAPHIC>",
      "position" : 3
    },
    {
      "token" : "会",
      "start_offset" : 4,
      "end_offset" : 5,
      "type" : "<IDEOGRAPHIC>",
      "position" : 4
    },
    {
      "token" : "加",
      "start_offset" : 6,
      "end_offset" : 7,
      "type" : "<IDEOGRAPHIC>",
      "position" : 5
    },
    {
      "token" : "油",
      "start_offset" : 7,
      "end_offset" : 8,
      "type" : "<IDEOGRAPHIC>",
      "position" : 6
    }
  ]
}

分词后

POST _analyze
{
  "analyzer": "ik_smart",
  "text": "北京冬奥会，加油！"
}

{
  "tokens" : [
    {
      "token" : "北京",
      "start_offset" : 0,
      "end_offset" : 2,
      "type" : "CN_WORD",
      "position" : 0
    },
    {
      "token" : "冬奥会",
      "start_offset" : 2,
      "end_offset" : 5,
      "type" : "CN_WORD",
      "position" : 1
    },
    {
      "token" : "加油",
      "start_offset" : 6,
      "end_offset" : 8,
      "type" : "CN_WORD",
      "position" : 2
    }
  ]
}
