I. 创建LicenseVerifier.java文件
[root@linuxea.com-Node61 /elk/]# cat 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;
}
}
II. 编译class文件
[root@linuxea.com-Node49 ~/elk]# javac -cp "/usr/share/elasticsearch/lib/elasticsearch-5.5.1.jar:/usr/share/elasticsearch/lib/lucene-core-6.6.0.jar:/usr/share/elasticsearch/plugins/x-pack/x-pack-5.5.1.jar" LicenseVerifier.java
[root@linuxea.com-Node49 ~/elk]# ls
LicenseVerifier.class
LicenseVerifier.java
[root@linuxea.com-Node49 ~/elk]# cd /usr/share/elasticsearch/plugins/x-pack/
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack]# mkdir test
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack]# mv x-pack-5.5.1.jar test/
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack]#
备份下x-pack-5.5.1.jar
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test]# cp xvf x-pack-5.5.1.jar /opt
解压
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test]# jar xvf x-pack-5.5.1.jar
替换class
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test]# cd org/elasticsearch/license
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test/org/elasticsearch/license]# cp /root/elk/LicenseVerifier.class ./
回到test目录打包
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test/org/elasticsearch/license]# cd /usr/share/elasticsearch/plugins/x-pack/test/
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test]# jar cvf x-pack-5.5.1.jar .
将打包好的文件放回x-pack目录下
[root@linuxea.com-Node49 /usr/share/elasticsearch/plugins/x-pack/test]# cp x-pack-5.5.1.jar ../
III. 申请license
https://license.elastic.co/registration
申请完成后很快会发送到邮箱，而后修改license文件
它分有不同的版本，版本有不同的权限，如下：
open source开源版本
basic基础版本
gold是黄金版
PLATINUM铂金版curl -XPUT -u elastic 'http://<host>:<port>/_xpack/license' -H "Content-Type: application/json" -d @license.json
IV. 修改license
申请一个license后会发到邮箱，然后修改下即可
{"license":{"uid":"d13W1FM-ef9XWi-45eAKLH6-afT5b4-b8erC7460","type":"platinum","issue_date_in_millis":11042324000000,"expiry_date_in_millis":2535123399999,"max_nodes":100,"issued_to":"sean wang (alibaba)","issuer":"Web Form","signature":"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","start_date_in_millis":1504224000000}}
将文件保存license.json
没修改前：
[root@linuxea.com-Node49 ~/elk]# curl -XGET -u elastic:linuxea 'http://10.0.1.49:9200/_license'
{
"license" : {
"status" : "active",
"uid" : "427cbb8e-9d96-435f-b56d-fa2efeb438c5",
"type" : "trial",
"issue_date" : "2017-09-01T14:28:04.736Z",
"issue_date_in_millis" : 1504276084736,
"expiry_date" : "2017-10-01T14:28:04.736Z",
"expiry_date_in_millis" : 1506868084736,
"max_nodes" : 1000,
"issued_to" : "linuxea-app",
"issuer" : "elasticsearch",
"start_date_in_millis" : -1
}
}
输入密码进行修改：
[root@linuxea.com-Node49 ~/elk]# curl -XPUT -u elastic 'http://10.0.1.49:9200/_xpack/license' -H "Content-Type: application/json" -d @license.json
Enter host password for user 'elastic':
{"acknowledged":true,"license_status":"valid"}
修改完成后查看
[root@linuxea.com-Node49 ~/elk]# curl -XPUT -u elastic 'http://10.0.1.49:9200/_xpack/license' -H "Content-Type: application/json"curl -XGET -u elastic:linuxea 'http://10.0.1.49:9200/_license'
