es7.9.3安装&kibana&同义词&ik分词器&拼音

一、es安装 1.1、配置

config/elasticsearch.yml

# 打开节点名称
node.name: chb2
# 这里的node-1为node-name配置的值
cluster.initial_master_nodes:["chb2"]
# 外部ip访问elasticsearch
network.host: 0.0.0.0

1.2、Ps:常见报错

[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] elasticsearch用户拥有的内存权限太小，至少需要262144；

//需要切换到root用户
sysctl -w vm.max_map_count=262144
//查看结果
sysctl -a|grep vm.max_map_count
//显示
vm.max_map_count = 262144
//修改之后，如果重启虚拟机将失效！！！
//解决办法：
//在   /etc/sysctl.conf文件最后添加一行
vm.max_map_count=262144

[2]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured 修改ES配置文件：config/elasticsearch.yml

//解开注释
cluster.initial_master_nodes: ["node-1", "node-2"]

二、kibana安装

vim kibana.yml

server.port: 5601

server.host: "0.0.0.0"

elasticsearch.hosts: ["http://192.168.200.110:9200"]

2.2、问题 2.2.1、Error: Could not close browser client handle!

在kibana的config中的kibana.yml中配置

elasticsearch.hosts: [“http://192.168.147.52:9200”]
xpack.reporting.capture.browser.chromium.disableSandbox: true
xpack.reporting.capture.browser.chromium.proxy.enabled: false
xpack.reporting.enabled: false

详细请参考： https://www.elastic.co/guide/en/kibana/current/settings.html kibana官方配置 https://www.cnblogs.com/sanduzxcvbnm/p/12677691.html https://www.ucloud.cn/yun/34216.html

三、ik分词器 3.1、ik配置

1、下载ik分词器 https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.9.3 2、解压到es的plugins目录下 3、重启es

3.2、配置自定义词库

1、配置自定义词库文件 对于部分专业词语，我们不想进行分词，所以ik分词器提供自定义词库 修改plugins/ik/config/IKAnalyzer.cfg.xml，可以使用本地自定义词库，也可以使用远程分词库（建议使用远程，这样不用每次重启es集群）

        IK Analyzer 扩展配置
        
        custom.dic
         
        
        
        
        
        

3、重启es

配置自定义词库前

配置自定义词库后

四、同义词 4.1、配置

1、配置同义词词库 2、重启 3、创建索引，设置settings

PUT test1
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 1,
    "analysis": {
      "filter": {
        "word_sync": {
          "type": "synonym",
          "synonyms_path": "analysis/synonym.txt"
        }
      },
      "analyzer": {
        "ik_sync_smart": {
          "filter": [
            "word_sync"
          ],
          "type": "custom",
          "tokenizer": "ik_smart"
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "name": {
        "type": "text",
        "fields": {
          "synoword": {
            "type": "text",
            "analyzer": "ik_sync_smart"
          }
        }
      }
    }
  }
}

五、拼音 5.1、配置pinyin插件

1、下载plugin https://github.com/medcl/elasticsearch-analysis-pinyin/releases/tag/v7.9.3 2、解压刀plugins目录下的pinyin目录 3、重启es

5.4、测试拼音

六、综合

1、创建index

PUT test1
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 1,
    "analysis": {
      "filter": {
        "word_sync": {
          "type": "synonym",
          "synonyms_path": "analysis/synonym.txt"
        }
      },
      "analyzer": {
        "ik_sync_smart": {
          "filter": [
            "word_sync"
          ],
          "type": "custom",
          "tokenizer": "ik_smart"
        },
        "pinyin_analyzer": {
          "type": "custom",
          "tokenizer": "pinyin_tokenizer"
        }
      },
      "tokenizer": {
        "pinyin_tokenizer": {
          "type": "pinyin"
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "name": {
        "type": "text",
        "fields": {
          "synoword": {
            "type": "text",
            "analyzer": "ik_sync_smart"
          },
          "pinyin": {
            "type": "text",
            "analyzer": "pinyin_analyzer"
          }
        }
      }
    }
  }
}

2、添加数据

PUT test1/_doc/1
{
  "name": "全季"
}
PUT test1/_doc/2
{
  "name": "拳击馆"
}

PUT test1/_doc/3
{
  "name": "汉庭"
}

3、查询
