ElasticSearch Xpack 6.3.0版本破解關鍵步驟（Win10下編譯Liscense驗證文件）

ES Xpack破解的關鍵步驟在於x-pack-core-xxx.jar包中的Liscense驗證文件替換。需要替換的文件共兩個XPackBuild .class和LicenseVerifier.class。從6.3版本開始，ES已將Xｐａｃｋ的源碼公佈出來，以下兩個新建文件，也可在GItHUb上找到ES6.3源碼。

1. 新建XPackBuild .java文件：

   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;
   
   /**
    * Information about the built version of x-pack that is running.
    */
   public class XPackBuild {
   
       public static final XPackBuild CURRENT;
   
       static {
           final String shortHash;
           final String date;
   
           Path path = getElasticsearchCodebase();
           if (path.toString().endsWith(".jar")) {
              /** try (JarInputStream jar = new JarInputStream(Files.newInputStream(path))) {
                   Manifest manifest = jar.getManifest();
                   shortHash = manifest.getMainAttributes().getValue("Change");
                   date = manifest.getMainAttributes().getValue("Build-Date");
               } catch (IOException e) {
                   throw new RuntimeException(e);
               }*/
               shortHash = null;
               date = null;
           } else {
               // not running from a jar (unit tests, IDE)
               shortHash = "Unknown";
               date = "Unknown";
           }
   
           CURRENT = new XPackBuild(shortHash, date);
       }
   
       /**
        * 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;
       }
   }

2. 新建文件LicenseVerifier.java:

   package org.elasticsearch.license;
   
   import java.nio.*;
   
   import java.util.*;
   
   import java.security.*;
   
   import org.elasticsearch.common.xcontent.*;
   
   import org.apache.lucene.util.*;
   
   import org.elasticsearch.common.io.*;
   
   import java.io.*;
   
   public class LicenseVerifier
   
   {
   
       public static boolean verifyLicense(final License license, final byte[] encryptedPublicKeyData) {
   
           return true;
   
       }
   
       public static boolean verifyLicense(final License license) {
   
           return true;
   
       }
   
   }

    

3. 將以上兩個文件在CMD中編譯成class文件(直接在java文件所在的目錄打開CMD，並將此命令中jar包的位置替換成自己電腦中的相應位置即可)：

   編譯命令

   編譯LicenseVerifier.java文件	javac -cp "/e:/soft/elasticsearch-6.3.0/lib/elasticsearch-6.3.0.jar;/e:/soft/elasticsearch-6.3.0/lib/lucene-core-7.3.1.jar;/e:/soft/elasticsearch-6.3.0/modules/x-pack/x-pack-core/x-pack-core-6.3.0.jar" LicenseVerifier.java
   編譯XPackBuild.java.java文件	javac -cp "/e:/soft/elasticsearch-6.3.0/lib/elasticsearch-6.3.0.jar;/e:/soft/elasticsearch-6.3.0/lib/lucene-core-7.3.1.jar;/e:/soft/elasticsearch-6.3.0/modules/x-pack/x-pack-core/x-pack-core-6.3.0.jar;/e:/soft/elasticsearch-6.3.0/lib/elasticsearch-core-6.3.0.jar" XPackBuild.java

   
   
   
   
   
   
   
   
   
    

4. 將編譯好的class文件替換到x-pack-core-6.3.0.jar中，直接使用jar工具打開此jar包，是打開不是解壓，然後將以上兩個生成的class文件放到對應的包中，具體路徑可以看一下源文件的package。
5. 以上4步便是文件替換的步驟，至於其他的步驟大家可以參考網上的教程，例如，我就參考了這一片文章elasticsearch6.3.2之x-pack6.3.2破解安裝並配合kibana使用 。
6. 成功破解後權限什麼的都有，監控等等，登錄界面已有。
