原理介绍
我们平时为es安装x-pack组件，用elasticsearch-plugin install x-pack ，安装成功后。
1**.cd $es目录/pulgins/x-pack** 里面有一个x-pack-5.6.2.jar ，将jar包反编译 ，然后将里面的licence 的程序改下。再编译成jar包。
2.再对的ES存储中license配置改下就好。
！！怕有人急用，我此处免费上传我破解的两个版本jar包，可直接使用
具体操作
1.准备好替换的license文件
#vim LicenseVerifier.java
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| package org.elasticsearch.license; public class LicenseVerifier { ``public static boolean verifyLicense(``final License license, ``final byte``[] encryptedPublicKeyData) { ``return true``; ``} ``public static boolean verifyLicense(``final License license) { ``return true``; ``} } |
再将其编译成替换的class文件
#javac -cp "/usr/share/elasticsearch/lib/elasticsearch-5.6.2.jar:/usr/share/elasticsearch/lib/lucene-core-6.6.1.jar:/usr/share/elasticsearch/plugins/x-pack/x-pack-5.6.2.jar" LicenseVerifier.java
会成了 LicenseVerifier.class文件。
2.反编译目标jar包（注意备份）
#mkdir fanbianyi
#cp $es目录/pulgins/x-pack/x-pack-5.6.2.jar ./fanbianyi/
#cd fanbianyi
#jar -xvf x-pack-5.6.2.jar
#rm x-pack-5.6.2.jar
3.替换license的class
#cp $/LicenseVerifier.class org/elasticsearch/license/4.编译,重新打包jar包 。替换之前的jar包。
#cd fanbianyi
#jar -cvf x-pack-5.6.2.jar ./*
#mv x-pack-5.6.2.jar /usr/share/elasticsearch/plugins/x-pack
5.重启es
6.配置新的license文件
可以自己去申请一个，它会绑定uuid,申请的license为basic版，可以管一年。我们现在要将我们的basic版，改为platinum（白金版）。可以自己去申请一个
