ElasticSearch 6.8.18獲取白金授權 dbeaver連接測試

1.es下載地址

https://www.elastic.co/cn/downloads/past-releases#elasticsearch

2.編寫elasticsearch-6.8.18\modules\x-pack-core內x-pack-core-6.8.18.jar的class文件

LicenseVerifier.class內方法改為返回true，

import org.elasticsearch.license.License;

public class LicenseVerifier
{
  public static boolean verifyLicense(License paramLicense, byte[] paramArrayOfByte) { return true; }
  
  public static boolean verifyLicense(License paramLicense) { return true; }
}

XPackBuild.class內方法修改對jar包的認證。

import java.net.URISyntaxException;
import java.net.URL;
import java.nio.file.Path;
import org.elasticsearch.common.SuppressForbidden;
import org.elasticsearch.common.io.PathUtils;
import org.elasticsearch.xpack.core.XPackBuild;

public class XPackBuild
{
  public static final XPackBuild CURRENT;
  private String shortHash;
  private String date;
  
  @SuppressForbidden(reason = "looks up path of xpack.jar directly")
  static Path getElasticsearchCodebase() {
    URL uRL = XPackBuild.class.getProtectionDomain().getCodeSource().getLocation();
    try {
      return PathUtils.get(uRL.toURI());
    }
    catch (URISyntaxException uRISyntaxException) {
      throw new RuntimeException(uRISyntaxException);
    } 
  }
  
  XPackBuild(String paramString1, String paramString2) {
    this.shortHash = paramString1;
    this.date = paramString2;
  }
  
  public String shortHash() { return this.shortHash; }

  public String date() { return this.date; }
  static  {
    Path path = getElasticsearchCodebase();
    String str1 = null;
    String str2 = null;
    
    str1 = "Unknown";
    str2 = "Unknown";
    
    CURRENT = new XPackBuild(str1, str2);
  }
}

3.解壓jar包替換class后重新打包

jar uvf x-pack-core-6.8.18.jar -C x-pack-core-6.8.18/ .

4.官網申請授權json，郵箱填對，要收郵件

https://license.elastic.co/registration

5.下載並修改拿到的授權json

****“type”:“basic” 替換為 “type”:"platinum"
“expiry_date_in_millis”:1662163199999替換為 “expiry_date_in_millis”:3208416321000

也就是2022年的授權到2071年

5.配置es並啟動

elasticsearch.yml內新增一行內容 xpack.security.enabled: false

6.訪問es查看_license

7.導入修改后的license的json

8.再次查看_license

授權到2071年

9.配置yml文件內容

xpack.security.enabled: true     
xpack.security.transport.ssl.enabled: true

10.設置密碼項

bin下執行elasticsearch-setup-passwords interactive

11.頁面訪問輸入用戶名密碼

12.配置dbeaver訪問es（注意驅動版本一致）

13.結束。
