解锁x-pack白金限制

x-pack只给了30天的试用，可能我们摸清楚Elasticsearch怎么用就不止30天了。所以我们还是主动延长一下x-pack的使用期。
接下来我们演示在8.0.1版本下延长x-pack的试用期限。

获取`elastic`的源码

首先先去elastic的github仓库获取源码，我们需要以下两个文件：

elasticsearch-8.0.1\x-pack\plugin\core\src\main\java\org\elasticsearch\license\LicenseVerifier.java
elasticsearch-8.0.1\x-pack\plugin\core\src\main\java\org\elasticsearch\xpack\core\XPackBuild.java

修改`x-pack`源码

首先注释掉LicenseVerifier.java的校验代码：

/** Copyright Elasticsearch B.V. and/or licensed to Elasticsearch B.V. under one* or more contributor license agreements. Licensed under the Elastic License* 2.0; you may not use this file except in compliance with the Elastic License* 2.0.*/
package org.elasticsearch.license;import org.apache.lucene.util.BytesRef;
import org.apache.lucene.util.BytesRefIterator;
import org.elasticsearch.common.bytes.BytesReference;
import org.elasticsearch.core.internal.io.Streams;
import org.elasticsearch.xcontent.ToXContent;
import org.elasticsearch.xcontent.XContentBuilder;
import org.elasticsearch.xcontent.XContentFactory;
import org.elasticsearch.xcontent.XContentType;import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.nio.ByteBuffer;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.security.PublicKey;
import java.security.Signature;
import java.security.SignatureException;
import java.util.Arrays;
import java.util.Base64;
import java.util.Collections;/*** 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, PublicKey publicKey) {/*byte[] signedContent = null;byte[] publicKeyFingerprint = null;try {byte[] signatureBytes = Base64.getDecoder().decode(license.signature());ByteBuffer byteBuffer = ByteBuffer.wrap(signatureBytes);@SuppressWarnings("unused")int version = byteBuffer.getInt();int magicLen = byteBuffer.getInt();byte[] magic = new byte[magicLen];byteBuffer.get(magic);int hashLen = byteBuffer.getInt();publicKeyFingerprint = new byte[hashLen];byteBuffer.get(publicKeyFingerprint);int signedContentLen = byteBuffer.getInt();signedContent = new byte[signedContentLen];byteBuffer.get(signedContent);XContentBuilder contentBuilder = XContentFactory.contentBuilder(XContentType.JSON);license.toXContent(contentBuilder, new ToXContent.MapParams(Collections.singletonMap(License.LICENSE_SPEC_VIEW_MODE, "true")));Signature rsa = Signature.getInstance("SHA512withRSA");rsa.initVerify(publicKey);BytesRefIterator iterator = BytesReference.bytes(contentBuilder).iterator();BytesRef ref;while ((ref = iterator.next()) != null) {rsa.update(ref.bytes, ref.offset, ref.length);}return rsa.verify(signedContent);} catch (IOException | NoSuchAlgorithmException | SignatureException | InvalidKeyException e) {throw new IllegalStateException(e);} finally {if (signedContent != null) {Arrays.fill(signedContent, (byte) 0);}}*/return true;}private static final PublicKey PUBLIC_KEY;static {try (InputStream is = LicenseVerifier.class.getResourceAsStream("/public.key")) {ByteArrayOutputStream out = new ByteArrayOutputStream();Streams.copy(is, out);PUBLIC_KEY = CryptUtils.readPublicKey(out.toByteArray());} catch (IOException e) {throw new AssertionError("key file is part of the source and must deserialize correctly", e);}}public static boolean verifyLicense(final License license) {//return verifyLicense(license, PUBLIC_KEY);return true;}
}

然后修改XPackBuild.java

/** Copyright Elasticsearch B.V. and/or licensed to Elasticsearch B.V. under one* or more contributor license agreements. Licensed under the Elastic License* 2.0; you may not use this file except in compliance with the Elastic License* 2.0.*/
package org.elasticsearch.xpack.core;import org.elasticsearch.core.PathUtils;
import org.elasticsearch.core.SuppressForbidden;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);}} else {// not running from a jar (unit tests, IDE)shortHash = "Unknown";date = "Unknown";}*/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;}
}

编译java文件

编译环境：Ubuntu
Java版本：Openjdk17
Elasticsearch版本：8.0.1

安装Elasticsearch

安装Elasitcsearch为了提供编译需要的jar包。

下载并安装PGP Key

$ wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo gpg --dearmor -o /usr/share/keyrings/elasticsearch-keyring.gpg

安装Elasticsearch Debain Package

apt-get update && sudo apt-get install elasticsearch

安装java环境

安装openjdk17

$ apt install openjdk-17-jdk

测试是否安装成功

$ java --version
openjdk 17.0.1 2021-10-19
OpenJDK Runtime Environment (build 17.0.1+12-Ubuntu-120.04)
OpenJDK 64-Bit Server VM (build 17.0.1+12-Ubuntu-120.04, mixed mode, sharing)

将java源码编译为class文件

javac -cp "/usr/share/elasticsearch/lib/elasticsearch-8.0.1.jar:/usr/share/elasticsearch/lib/lucene-core-9.0.0.jar:/usr/share/elasticsearch/modules/x-pack-core/x-pack-core-8.0.1.jar:/usr/share/elasticsearch/lib/elasticsearch-x-content-8.0.1.jar:/usr/share/elasticsearch/lib/elasticsearch-core-8.0.1.jar" /root/LicenseVerifier.java
javac -cp "/usr/share/elasticsearch/lib/elasticsearch-8.0.1.jar:/usr/share/elasticsearch/lib/lucene-core-9.0.0.jar:/usr/share/elasticsearch/modules/x-pack-core/x-pack-core-8.0.1.jar:/usr/share/elasticsearch/lib/elasticsearch-x-content-8.0.1.jar:/usr/share/elasticsearch/lib/elasticsearch-core-8.0.1.jar" /root/XPackBuild.java

我们会得到LicenseVerifier.class和XPackBuild.class两个编译好的class文件

修改x-pack-core

文件位置:

/usr/share/elasticsearch/modules/x-pack-core/x-pack-core-8.0.1.jar

把x-pack-core-8.0.1.jar复制到任意位置，然后解包：

$ jar -xvf x-pack-core-8.0.1.jar

删除当前文件夹下的x-pack-core-8.0.1.jar
覆盖破解好的文件：
LicenseVerifier.class 路径在 /org/elasticsearch/license/LicenseVerifier.class
XPackBuild.class 路径在 /org/elasticsearch/xpack/core/XPackBuild.class
重新打包x-pack-core-8.0.1.jar

$ jar cvf x-pack-core-8.0.1.jar *

把破解好的文件覆盖到/usr/share/elasticsearch/modules/x-pack-core/x-pack-core-8.0.1.jar就完成破解。

制作Docker镜像

启动elasticsearch

$ docker run -d -p 9200:9200 --name=elasticsearch -e xpack.security.enabled=false -e discovery.type=single-node elasticsearch:8.0.1

用修改的x-pack-core-8.0.1.jar替换镜像内的原版

$ docker cp .\x-pack-core-8.0.1.jar elasticsearch:/usr/share/elasticsearch/modules/x-pack-core

修改镜像内文件的权限
首先以root用户进入容器

$ docker exec -it -u root elasticsearch /bin/bash

然后修改x-pack-core-8.0.1.jar的权限

$ cd /usr/share/elasticsearch/modules/x-pack-core
$ chmod -R 444 x-pack-core-8.0.1.jar
$ chown -R root x-pack-core-8.0.1.jar
$ chgrp -R root x-pack-core-8.0.1.jar
$ exit

重启容器

$ docker restart elasticsearch

生成镜像

$ docker commit elasticsearch elasticsearch:8.0.1C

使用elasticsearch:8.0.1C这个镜像再导入证书就可以直接激活白金权限了
6. 导出/导入镜像

# 导出镜像为tar文件
$ docker save -o elastic.tar elasticsearch：8.0.1C
# 导入tar镜像
$ docker load -i elastic.tar

激活白金授权

申请Basic License

到这个网址申请授权，我们会得到一个license.json。文件内容大概是下面这个样子

{"license": {"uid": "13370dd7-23e4-4470-ad2a-ccacb620f60a","type": "basic","issue_date_in_millis": 1563235200000,"expiry_date_in_millis": 2207746200000,"max_nodes": 10000,"issued_to": "netpro","issuer": "Web Form","signature": "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","start_date_in_millis": 1563235200000}
}
### 修改授权类型和过期时间

我们需要修改license.json的以下内容：

修改type为platinum
修改expiry_date_in_millis为2524579200999(过期时间为2050年)

导入授权

这里我们直接用别人修改好的授权文件license.json

{"license": {"uid": "13370dd7-23e4-4470-ad2a-ccacb620f60a","type": "platinum","issue_date_in_millis": 1563235200000,"expiry_date_in_millis": 3207746200000,"max_nodes": 10000,"issued_to": "bibi","issuer": "Web Form","signature": "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","start_date_in_millis": 1563235200000}
}

导入授权：

curl -XPUT -u elastic 'http://192.168.0.106:9200/_license' -H "Content-Type: application/json" -d @license.json

在kibana里能看到授权成功
