X-Pack是什么
X-pack是elasticsearch的一个扩展包，将安全，警告，监视，图形和报告功能捆绑在一个易于安装的软件包中，虽然x-pack被设计为一个无缝的工作，但是你可以轻松的启用或者关闭一些功能。
主要分一下步骤
1、修改x-pack-core-7.14.2.jar
拷贝ES目录下 ./modules/x-pack-core/x-pack-core-7.14.2.jar 文件并解压
解压之后找到一下两个文件
x-pack-core-7.14.2.jar/org/elasticsearch/license/LicenseVerifier.class
x-pack-core-7.14.2.jar/org/elasticsearch/xpack/core/XPackBuild.class
用以下两个java文件重新编译之后替换
创建以下两个java文件
LicenseVerifier.java
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;
}
}
XPackBuild.java
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;
}
}
拷贝以上两个java文件到es主目录
进入es主目录执行
javac -cp lib/elasticsearch-7.14.2.jar:modules/x-pack-core/x-pack-core-7.14.2.jar LicenseVerifier.java
javac -cp lib/elasticsearch-7.14.2.jar:lib/lucene-core-8.9.0.jar:modules/x-pack-core/x-pack-core-7.14.2.jar:lib/elasticsearch-core-7.14.2.jar XPackBuild.java
会生成两个新的class文件
LicenseVerifier.class
XPackBuild.class
分别替换
x-pack-core-7.14.2.jar/org/elasticsearch/license/LicenseVerifier.class
x-pack-core-7.14.2.jar/org/elasticsearch/xpack/core/XPackBuild.class
重新压缩成jar包x-pack-core-7.14.2.jar
替换./modules/x-pack-core/x-pack-core-7.14.2.jar
重启ES
去官网(https://license.elastic.co/registration)申请license后，下载下来是个JSON文件
主要替换两处 type 修改为 platinum （白金版）
expiry_date_in_millis 修改时间长一点2524579200999

"start_date_in_millis": 1700697600000
}
}
修改完之后在kibana页面上传新的许可证
或者通过命令行之后
curl -u elastic:密码 -XPUT 'https://127.0.0.1:9200/_xpack/license' -H "Content-Type: application/json" -d @license.json
返回 {“acknowledged”:true,“license_status”:“valid”} 就表示更改许可证成功 。
