• 1.下載對應版本的x-pack：

[root@lijie elk]# wget 'https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-5.5.1.zip'

• 2.安裝x-path

./elasticsearch-5.5.1/bin/elasticsearch-plugin install file:///usr/java/elk/xpack/x-pack-5.5.1.zip

./kibana-5.5.1-linux-x86_64/bin/kibana-plugin install file:///usr/java/elk/xpack/x-pack-5.5.1.zip
 

預設賬號密碼：

使用者名稱：elastic
密碼：changeme  

• 3.建立java檔案

vi LicenseVerifier.java

#內容
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;
    }
}

• 4.解壓下載的x-path外掛

unzip x-pack
 
-5.5.1.zip

如圖：

• 5.進行編譯，需要指定其他jar的classpath的路徑所以用javac -cp

javac -cp "/usr/java/elk/elasticsearch-5.5.1/lib/elasticsearch-5.5.1.jar:/usr/java/elk/elasticsearch-5.5.1/lib/lucene-core-6.6.0.jar:/usr/java/elk/xpack/elasticsearch/x-pack-5.5.1.jar" LicenseVerifier.java

• 6.替換class檔案

#建立臨時資料夾解壓jar
[hadoop@lijie xpack]$ mkdir mytest
[hadoop@lijie xpack]$ mv ./elasticsearch/x-pack-5.5.1.jar mytest/
[hadoop@lijie xpack]$ cd mytest/
[hadoop@lijie mytest]$ jar -xvf x-pack-5.5.1.jar
[hadoop@lijie mytest]$ rm -rf x-pack-5.5.1.jar

#刪除原檔案，將新編譯的拷貝到該位置
[hadoop@lijie mytest]$ rm -rf org/elasticsearch/license/LicenseVerifier.class 
[hadoop@lijie mytest]$ cp ../LicenseVerifier.class org/elasticsearch/license/

#重新打包
[hadoop@lijie mytest]$ jar -cvf x-pack-5.5.1.jar ./*

#覆蓋plugins資料夾裡面的jar包
[hadoop@lijie mytest]$ rm -rf /usr/java/elk/elasticsearch-5.5.1/plugins/x-pack/x-pack-5.5.1.jar 
[hadoop@lijie mytest]$ mv x-pack-5.5.1.jar /usr/java/elk/elasticsearch-5.5.1/plugins/x-pack

• 檢視可用日期（顯示只有1個月時間）：

[hadoop@lijie mytest]$ curl -XGET -u elastic:changeme 'http://192.168.80.123:9200/_license'

{
  "license" : {
    "status" : "active",
    "uid" : "ef3e9077-02f4-4096-85a2-67178c1b2e35",
    "type" : "trial",
    "issue_date" : "2017-10-19T17:30:45.602Z",
    "issue_date_in_millis" : 1508434245602,
    "expiry_date" : "2017-11-18T17:30:45.602Z",
    "expiry_date_in_millis" : 1511026245602,
    "max_nodes" : 1000,
    "issued_to" : "myes",
    "issuer" : "elasticsearch",
    "start_date_in_millis" : -1
  }
}

• 重啟es和kibana

就是填寫下申請，然後右鍵啟用下載license

將license上面的修改為

"type":"platinum"
"expiry_date_in_millis":253395907200000

#如下

建立一個檔案license.json,將上面的內容複製到裡面

然後執行：

[hadoop@lijie mytest]$ curl -XPUT -u elastic:changeme 'http://192.168.80.123:9200/_xpack/license?acknowledge=true' -H "Content-Type: application/json" -d @license.json

返回：
{"acknowledged":true,"license_status":"valid"}

在執行檢視過期時間以及版本：
