elasticsearch8和kibana部署遇到的坑

我本来使用的是最新版本的es 8.6.2。但是由于ik分词器只更新到8.6.1，所以就更改为部署8.6.1。在过程中遇到一些问题，这里做一个总结

环境：windows10

elasticsearch版本：8.6.1

一、修改es 用户密码的方式

在bin目录下执行命令 ./elasticsearch-reset-password -u elastic -i

二、kibana 使用用户名和密码登录

1. 修改kibana.yml 文件

elasticsearch.username: "elastic"
elasticsearch.password: "123456"
# 设置kibana为中文
i18n.locale: "zh-CN"

2. 启动kibana一直闪退

解决方案：

a. 在bin目录下，打开powershell，使用命令行

b. 执行 .\kibana.bat，这样就可以看到错误日志了

c. 查了网上说是因为kibana不能使用elastic 用户进行登录，需要新建用户

d. 在es的bin目录下执行 ./elasticsearch-users useradd test

e. 给test用户授权

./elasticsearch-users roles -a superuser test

./elasticsearch-users roles -a kibana_system test

f. 然后将kibana.yml文件中配置成test用户，重启kibana就可以了

三、elasticsearch-head通过用户名密码连接es

1. 修改 es 目录下config文件夹下面的elasticsearch.yml文件

#解决跨域问题
http.cors.enabled : true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,Content-Type,X-Requested-with,Content-Length

2. 重启es后，使用加上用户名和密码的地址访问es-head

http://localhost:9100/?auth_user=elastic&auth_password=123456

注意：这里是es-head地址，不是里面配置的es地址

三、springboot整合es8

不推荐使用spring-boot-starter-data-elasticsearch

原因：由于elasticsearch已经更新到8.6.X版本，但是spring-boot-starter-data-elasticsearch 里面最新集成的es还是6.8.2

如果修改8.6.1会报错

推荐采用es的Elasticsearch Java API Client

引入依赖

        
            co.elastic.clients
            elasticsearch-java
            8.6.1
        
        
            com.fasterxml.jackson.core
            jackson-databind
            2.12.3
        
        
            jakarta.json
            jakarta.json-api
            2.0.1
        

构建es client推荐使用ElasticSearchClient。RestHighLevelClient在es7.15之后已经废弃。

@Configuration
public class ElasticSearchClientConfig {

    @Bean
    public ElasticsearchClient elasticsearchClient() {
        RestClient client = RestClient.builder(new HttpHost("localhost", 9200)).build();
        ElasticsearchTransport transport = new RestClientTransport(client, new JacksonJsonpMapper());
        return new ElasticsearchClient(transport);
    }
}

如果配置了登录功能

@Configuration
public class ElasticSearchClientConfig {

    @Bean
    public ElasticsearchClient elasticsearchClient() {
        final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(
                AuthScope.ANY, new UsernamePasswordCredentials("test", "123456"));

        RestClient client = RestClient.builder(new HttpHost("localhost", 9200))
                .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                    @Override
                    public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpAsyncClientBuilder) {

                        return httpAsyncClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
                    }
                })
                .build();
        ElasticsearchTransport transport = new RestClientTransport(client, new JacksonJsonpMapper());
        return new ElasticsearchClient(transport);
    }
}

如果上面接入报错：

原因是因为elasticsearch-java 下依赖的elasticsearch-rest-client版本与es版本不一致导致，应该排除该包，单独配置为和es版本一致的版本。

解决方案，修改依赖：
