ElasticSearch7.5 白金版破解

官網下載壓縮包解壓後就能夠使用bin\elasticsearch.bat運行了，可是運行時有諸多限制，好比jdbc的部分，開源版本還不能正常使用，查看不一樣版本的功能對比。

破解過程：

注意：D:\develop\是我本機路徑，你在操做時應該修改爲你的路徑。

1，將 D:\develop\elasticsearch-7.5.0\modules\x-pack-core\目錄下的x-pack-core-7.5.0.jar文件賦值一份，

2，手動建立XPackBuild.java和LicenseVerifier.java兩個文件，

• LicenseVerifier.java內容爲：

  package org.elasticsearch.xpack.core;
  
  import org.elasticsearch.common.SuppressForbidden;
  import org.elasticsearch.common.io.PathUtils;
  
  import java.io.IOException;
  import java.net.URISyntaxException;
  import java.net.URL;
  import java.nio.file.Files;
  import java.nio.file.Path;
  import java.util.jar.JarInputStream;
  import java.util.jar.Manifest;
  
  public class XPackBuild {
  
      public static final XPackBuild CURRENT;
  
      static {
          CURRENT = new XPackBuild("Unknown", "Unknown");
      }
  
      /**
       * Returns path to xpack codebase path
       */
      @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 bogus) {
              throw new RuntimeException(bogus);
          }
      }
  
      private String shortHash;
      private String date;
  
      XPackBuild(String shortHash, String date) {
          this.shortHash = shortHash;
          this.date = date;
      }
  
      public String shortHash() {
          return shortHash;
      }
  
      public String date() {
          return date;
      }
  }

• LicenseVerifier.java文件的內容爲：

  package org.elasticsearch.license;
  
  /**
   * Responsible for verifying signed licenses
   */
  public class LicenseVerifier {
  
      /**
       * verifies the license content with the signature using the packaged
       * public key
       * @param license to verify
       * @return true if valid, false otherwise
       */
      public static boolean verifyLicense(final License license, byte[] publicKeyData) {
          return true;
      }
  
      public static boolean verifyLicense(final License license) {
          return true;
      }
  }

3，使用javac 編譯這兩個java文件，須要引入import的依賴，使用-cp參數，須要依賴本來的x-pack-core-7.5.0.jar，lucene-core-8.3.0.jar，elasticsearch-7.5.0.jar，elasticsearch-core-7.5.0.jar這四個jar包,對應的文件都在安裝目錄，有的在lib目錄下，有的在modules目錄下。編譯命令：

javac -cp "D:\develop\elasticsearch-7.5.0\modules\x-pack-core\x-pack-core-7.5.0.jar;D:\develop\elasticsearch-7.5.0\lib\lucene-core-8.3.0.jar;D:\develop\elasticsearch-7.5.0\lib\elasticsearch-7.5.0.jar;D:\develop\elasticsearch-7.5.0\lib\elasticsearch-core-7.5.0.jar"  C:\Users\baibook\Desktop\XPackBuild.java

javac -cp "D:\develop\elasticsearch-7.5.0\modules\x-pack-core\x-pack-core-7.5.0.jar;D:\develop\elasticsearch-7.5.0\lib\lucene-core-8.3.0.jar;D:\develop\elasticsearch-7.5.0\lib\elasticsearch-7.5.0.jar;D:\develop\elasticsearch-7.5.0\lib\elasticsearch-core-7.5.0.jar"  C:\Users\baibook\Desktop\LicenseVerifier.java

而後就會在桌面產生對應的class文件。用壓縮軟件打開第1步中複製的x-pack-core-7.5.0.jar

將本身編譯的class文件覆蓋到上圖對應的目錄後，將該jar包與安裝目錄的進行替換，而後重啓Elasticsearch。

4，更新許可證

官方申請地址： https://register.elastic.co/marvel_register

公司地址什麼課以隨便填寫，郵箱要填好，而後收到郵件，進行文件下載。 下載下來，修改裏面的內容，主要是把 "basic" 改成 "platinum" 即白金版，"expiry_date_in_millis" 這個時間戳改大點，就夠用了。

{"license":{"uid":"21213675-4eee-41fe-a3db-f0f6eb731ac0","type":"platinum","issue_date_in_millis":1578009600000,"expiry_date_in_millis":16097183999990,"max_nodes":100,"issued_to":"test bai (test)","issuer":"Web Form","signature":"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","start_date_in_millis":1578009600000}}

能夠在Kibana上上傳許可證激活，也能夠用命令的方式

curl -XPUT 'http://localhost:9200/_xpack/license' -H "Content-Type: application/json" -d @license.json

命令方式 返回 {"acknowledged":true,"license_status":"valid"} 就表示續命成功了 。

在Kibana上能夠看到
