使用elasticsearch和search-ui搭建自己的搜索引擎，快速查找资源和文件。如果对代码感兴趣，相关代码已在github上开源，欢迎fork代码。
搭建elasticsearch
先搭建eleasticsearch再搭建kibana
搭建elasticsearch
mkdir elasticsarchcd elasticsarchmkdir -p /es/pluginsmkdir -p /es/datamkdir -p /es/logsmkdir -p /es/configvim docker-compose.yml
编辑docker-compose.yml文件，内容如下：
version: '3'services: elasticsearch: image: elasticsearch:8.9.0 container_name: elasticsearch privileged: true environment: - "cluster.name=elasticsearch" #设置集群名称为elasticsearch - "discovery.type=single-node" #以单一节点模式启动 - "ES_JAVA_OPTS=-Xms512m -Xmx1096m" #设置使用jvm内存大小 - bootstrap.memory_lock=true volumes: - ./es/plugins:/usr/share/elasticsearch/plugins #插件文件挂载 - ./es/data:/usr/share/elasticsearch/data:rw #数据文件挂载 - ./es/logs:/usr/share/elasticsearch/logs:rw - ./es/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml ports: - 9200:9200 - 9300:9300 deploy: resources: limits: cpus: "2" memory: 1000M reservations: memory: 200M
其中
./es/config/elasticsearch.yml的内容如下，可按需修改：
cluster.name: "elasticsearch"network.host: 0.0.0.0
启动elasticsearch
配置完成后，启动elasticsearch。
docker-compose --compatibility up -d
同时进入elasticsearch容器内部，修改密码。
# 进入容器内部docker exec -it elasticsearch bash# 修改密码elasticsearch@4c37fcfb6f13:~$ ls LICENSE.txt NOTICE.txt README.asciidoc bin config data jdk lib logs modules plugins elasticsearch@4c37fcfb6f13:~$ bin/elasticsearch-reset-password --username elastic -ibin/elasticsearch-reset-password --username kibana -i
搭建kibana
mkdir kibanacd kibanavim docker-compose.yml
docker-compose.yml的内容如下：
version: '3'services: kibana: image: kibana:8.9.0 container_name: kibana volumes: - ./kibana.yml:/usr/share/kibana/config/kibana.yml ports: - 5601:5601 deploy: resources: limits: cpus: "1" memory: 1000M reservations: memory: 200M
kibana.yml的文件内容如下，可按需修改：
elasticsearch.hosts: http://elasticsearch:9200elasticsearch.username: kibanaelasticsearch.password: kibanaserver.host: "0.0.0.0"server.name: kibanaxpack.monitoring.ui.container.elasticsearch.enabled: truei18n.locale: zh-CN
启动kibana，
docker-compose --compatibility up -d
同时搭建eleasticsearch和kibana
使用docker-compose启动elasticsearch
编辑docker-compose.yml文件，内容如下：
version: '3'services: elasticsearch: image: elasticsearch:8.9.0 container_name: elasticsearch privileged: true environment: - "cluster.name=elasticsearch" #设置集群名称为elasticsearch - "discovery.type=single-node" #以单一节点模式启动 - "ES_JAVA_OPTS=-Xms512m -Xmx1096m" #设置使用jvm内存大小 - bootstrap.memory_lock=true volumes: - ./es/plugins:/usr/local/dockercompose/elasticsearch/plugins #插件文件挂载 - ./es/data:/usr/local/dockercompose/elasticsearch/data:rw #数据文件挂载 - ./es/logs:/usr/local/dockercompose/elasticsearch/logs:rw ports: - 9200:9200 - 9300:9300 deploy: resources: limits: cpus: "2" memory: 1000M reservations: memory: 200M kibana: image: kibana:8.9.0 container_name: kibana depends_on: - elasticsearch #kibana在elasticsearch启动之后再启动 volumes: - ./es/config/kibana:/usr/share/kibana/config/kibana.yaml ports: - 5601:5601
其中kibana.yaml的内容如下：
elasticsearch.hosts: http://elasticsearch:9200server.host: "0.0.0.0"server.name: kibanaxpack.monitoring.ui.container.elasticsearch.enabled: truei18n.locale: zh-CN
进入elasticsearch终端，修改elasticsearch密码
# 进入容器内部docker exec -it elasticsearch bash# 修改密码elasticsearch@4c37fcfb6f13:~$ ls LICENSE.txt NOTICE.txt README.asciidoc bin config data jdk lib logs modules plugins elasticsearch@4c37fcfb6f13:~$ bin/elasticsearch-reset-password --username elastic -iWARNING: Owner of file [/usr/share/elasticsearch/config/users] used to be [root], but now is [elasticsearch]WARNING: Owner of file [/usr/share/elasticsearch/config/users_roles] used to be [root], but now is [elasticsearch] This tool will reset the password of the [elastic] user.

Please confirm that you would like to continue [y/N]y Enter password for [elastic]: Re-enter password for [elastic]: Password for the [elastic] user successfully reset. elasticsearch@4c37fcfb6f13:~$
生成kibana的token
# 重启容器然后进入容器内部生成kibana的tokendocker exec -it elasticsearch bash elasticsearch@4c37fcfb6f13:~$ bin/elasticsearch-create-enrollment-token -s kibana
获取kibana验证码
# 在浏览器打开http://ip:5601,粘贴kibana的token，然后进入kibana容器内部获取验证码sudo docker exec -it kibana bash kibana@fce2ab8aec1e:~$ ls LICENSE.txt NOTICE.txt README.txt bin config data logs node node_modules package.json packages plugins src x-pack kibana@fce2ab8aec1e:~$ bin/kibana-verification-code Your verification code is: 042 943
搭建search-ui
创建search-ui项目
npm install -g create-react-app# 创建名为doc_index的项目create-react-app doc_index --use-npmcd doc_indexnpm install --save @elastic/react-search-ui @elastic/search-ui-app-search-connector @elastic/search-ui-elasticsearch-connector
启动search-ui项目
npm start
创建api_key
登录kibana，进入到
/app/management/security/api_keys/，创建一个api_key并记录api_key.
创建索引
登录kibana的dev_tools创建和设置索引：
# 创建索引PUT /doc_index# 设置索引属性PUT /doc_index/_mapping
{ "properties":{ "title":{ "type":"text", "fields":{ "suggest": { "type": "search_as_you_type"
}
}
}, "category":{ "type":"text"
}, "url":{ "type":"text"
}
}
}# 设置查询返回的最大条数PUT /doc_index/_settings
{ "index" : { "max_result_window": 500000
}
}导入数据
# 插入单条数据POST /doc_index/_bulk
{"index":{}}
{"title":"test","category":"test","url":"http://localhost:3000"}## 批量插入POST /doc_index/_bulk
{"index":{}}
{"title":"test2","category":"test","url":"http://localhost:3001"}
{"index":{}}
{"title":"dir","category":"test","url":"http://localhost:3002"}
{"index":{}}
{"title":"ddssd","category":"test","url":"http://localhost:3003"}
{"index":{}}
{"title":"测试","category":"test","url":"http://localhost:3004"}当然也可以用命令行插入，如使用curl命令：
curl --username username:password -H "Content-Type: application/json" -XPOST 192.168.56.130:9200/bank/account/_bulk?pretty --data-binary "@test.json"
其中--username指定elasticsearch的用户名和密码，test.json的内容如下：
{"index":{}}
{"title":"test2","category":"test","url":"http://localhost:3001"}
{"index":{}}
{"title":"dir","category":"test","url":"http://localhost:3002"}
{"index":{}}
{"title":"ddssd","category":"test","url":"http://localhost:3003"}
{"index":{}}
{"title":"测试","category":"test","url":"http://localhost:3004"}完整数据插入命令如下：
PUT /doc_index/_mapping
{ "properties":{ "title":{ "type":"text", "fields":{ "suggest": { "type": "search_as_you_type"
}
}
}, "category":{ "type":"text"
}, "url":{ "type":"text"
}
}
}
PUT /doc_index/_settings
{ "index" : { "max_result_window": 500000
}
}
GET /doc_index/_search
POST /doc_index/_bulk
{"index":{}}
{"title":"test2","category":"test","url":"http://localhost:3001"}
{"index":{}}
{"title":"dir","category":"test","url":"http://localhost:3002"}
{"index":{}}
{"title":"ddssd","category":"test","url":"http://localhost:3003"}
{"index":{}}
{"title":"测试","category":"test","url":"http://localhost:3004"}完善search-ui
search-ui下载下来之后，还没有绑定数据，此时还需要修改app.js来进行适配。
app.js需更改成：
// Step #1, import statementsimport React from "react";// 这里需要注意app和网页的接口名称不一样import ElasticsearchAPIConnector from "@elastic/search-ui-elasticsearch-connector";import {
PagingInfo,
ResultsPerPage,
Paging,
SearchProvider,
Results,
SearchBox,
Sorting
} from "@elastic/react-search-ui";import { Layout } from "@elastic/react-search-ui-views";import "@elastic/react-search-ui-views/lib/styles/styles.css";// Step #2, The connectorconst connector = new ElasticsearchAPIConnector({ host: "http://elasticsearch:9200", // elasticsearch的地址 apiKey: "WjUxNVpZc0JTb3pYN2J6cEdqRHQ6R3Y0all0R1dTai1LSjhqMGc5THFVdw==", // elasticsearch 的登录秘钥，在kibana上生成 index: "doc_index" // 要访问的索引的地址});
// Step #3: Configuration optionsconst configurationOptions = { searchQuery: { search_fields: { title: { weight: 3
}, url: {}, category: {}
}, result_fields: { title: { snippet: {}
}, url: { snippet: {}
}, category: { snippet: {}
}
}
}, apiConnector: connector, alwaysSearchOnInitialLoad: true};// step4 show result export default function App() { return (
<SearchProvider config={configurationOptions}>
<div className="App">
<Layout
header={<SearchBox />}
// 要展示的标题和标题对应的连接
bodyContent={<Results titleField="title" urlField="url" />}
bodyHeader={
<>
<PagingInfo />
<ResultsPerPage />
</>
}
bodyFooter={<Paging />}
/>
</div>
</SearchProvider>
);
}还可以修改一下public下面的title标签，修改成自己的项目标签。如：
<title>doc_index</title>
