转载地址：https://xiaochengxinyizhan.blog.csdn.net/article/details/89482433

 

安装步骤：

下载地址：https://www.elastic.co/cn/start?elektra=home&&storm=banner

解压：

启动安装程序

自动弹出CMD命令

执行http://localhost:9200/

修改 elasticsearch.yml

文件需加入的内容
http.cors.enabled: true 
http.cors.allow-origin: "*"
node.master: true
node.data: true
放开注释的内容
放开network.host: 192.168.0.1的注释并改为network.host: 0.0.0.0（这里如果不修改的话，外网无法访问与是否安装head无关）
放开cluster.name；node.name；http.port的注释

双击 elasticsearch.bat 重启

安装node.js

下载链接：https://nodejs.org/en/download/

下载head插件
步骤命令：

 git clone git://github.com/mobz/elasticsearch-head.git
 cd elasticsearch-head
 npm install
 npm run start
 open http://localhost:9100/
下载地址：https://github.com/mobz/elasticsearch-head

如果不想这么安装上面的那么多可以直接安装Google的插件

只支持一个index的type现在称为doc

（1）No handler for type [string] declared on field

{"reason":"Failed to parse mapping [umc_synclog_data]:
 No handler for type [string] declared on field [response]",
 "caused_by":{"reason":"No handler for type [string] declared on field [response]",
 "type":"mapper_parsing_exception"},
 "type":"mapper_parsing_exception",

 "type":"mapper_parsing_exception"}]}

ES版本5.x以上没有string类型，改为text或者keyword

（2）analyzer [ik_max_word] not found for field

{"reason":"Failed to parse mapping[umc_synclog_data]: 
analyzer [ik_max_word] not found for field[response]",
"caused_by":{"reason":"analyzer [ik_max_word] not foundfor field[response]",
"type":"mapper_parsing_exception"},

"type":"mapper_parsing_exception"}]}

需要修改配置文件去掉旧有分词

（3）ERROR org.springframework.data.elasticsearch.repository.support.AbstractElasticsearchRepository - failed to load elasticsearch nodes : org.elasticsearch.client.transport.NoNodeAvailableException:
None of the configured nodes are available:

（4）使用创建实例的时候默认client客户端实例化需要初始化两个管理员一个是集群管理员，一个是索引管理员。

Caused by: java.lang.NullPointerException
at org.elasticsearch.common.io.stream.StreamOutput.writeString

Caused by: java.lang.ClassNotFoundException: org.elasticsearch.common.transport.InetSocketTransportAddress
缺少jar包：spring-data-elasticSearch的话看这个链接
https://elasticsearch.cn/question/5002
原生的jar包引入的话加下面的这个jar包

            org.elasticsearch.plugin
            transport-netty4-client
            6.3.2
