elasticSearch+kibana+logstash+filebeat集群改成https認證

這篇具有很好參考價值的文章主要介紹了elasticSearch+kibana+logstash+filebeat集群改成https認證。希望對大家有所幫助。如果存在錯誤或未考慮完全的地方，請大家不吝賜教，您也可以點擊"舉報違法"按鈕提交疑問。

一、生成相關證書

ps：主節(jié)點操作

切換用戶：su es
進入目錄：cd /home/es/elasticsearch-7.6.2

創(chuàng)建文件：vi instances.yml

instances:
  - name: "master" 
    ip: 
      - "192.168.248.10"
  - name: "slave1"
    ip:
      - "192.168.248.11"
  - name: "slave2"
    ip:
      - "192.168.248.12"
  - name: "kibana"
    ip:
      - "192.168.248.10"
  - name: "logstash"
    ip:
      - "192.168.248.10"   
  - name: "filebeat"
    ip:
      - "192.168.248.10"

生成證書：/home/es/elasticsearch-7.6.2/bin/elasticsearch-certutil cert ca --pem --in instances.yml --out certs.zip
解壓得到各個證書：unzip certs.zip

二、配置elasticSearh

ps：三個節(jié)點

切換用戶：su es
將解壓得到的三個文件夾文件拷貝到各個節(jié)點的/home/es/elasticsearch-7.6.2/config下，如master節(jié)點：ca.crt、master.crt、master.key

三個節(jié)點配置，末尾添加配置：vi /home/es/elasticsearch-7.6.2/config/elasticsearch.yml
ps1：根據(jù)名字配置master和slave1和slave2
ps2：如果之前配置過密碼，需要將密碼的配置先移除

xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.key: master.key
xpack.security.http.ssl.certificate: master.crt
xpack.security.http.ssl.certificate_authorities: ca.crt

xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.key: master.key
xpack.security.transport.ssl.certificate: master.crt
xpack.security.transport.ssl.certificate_authorities: ["ca.crt"]

如果是用root用戶拷貝的，記得賦權：chown -R es:es /home/es

啟動

cd /home/es/elasticsearch-7.6.2/bin
nohup /home/es/elasticsearch-7.6.2/bin/elasticsearch &

設置密碼：/home/es/elasticsearch-7.6.2/bin/elasticsearch-setup-passwords interactive

ps1：可以統(tǒng)一設置一個密碼ffcsict123

ps2：如果已經(jīng)設置過密碼了，可以忽略?；蛘咭部梢詣h除es的 .security-7 索引，重新執(zhí)行設置密碼的操作也可以

三、配置kibana

將kibana證書放到/home/es/kibana-7.6.2-linux-x86_64/config下：kibana.crt、ca.crt、kibana.key

配置：vi /home/es/kibana-7.6.2-linux-x86_64/config/kibana.yml

# 修改
elasticsearch.hosts: ["https://192.168.248.10:9200","https://192.168.248.11:9200","https://192.168.248.12:9200"]

# 末尾添加
# 這三個路徑寫成相對路徑會被錯，寫絕對路徑才行，不知道為啥
server.ssl.enabled: true
server.ssl.certificate: /home/es/kibana-7.6.2-linux-x86_64/config/kibana.crt
server.ssl.key: /home/es/kibana-7.6.2-linux-x86_64/config/kibana.key
elasticsearch.ssl.certificateAuthorities: ["/home/es/kibana-7.6.2-linux-x86_64/config/ca.crt"]

elasticsearch.username: "kibana"
elasticsearch.password: "ffcsict123"

如果是用root用戶拷貝的，記得賦權：chown -R es:es /home/es
啟動：nohup /home/es/kibana-7.6.2-linux-x86_64/bin/kibana &
訪問：https://192.168.248.10:5601

四、配置logstash

將logstash證書放到/home/es/logstash-7.6.2/config下：logstash.crt、ca.crt、logstash.key

修改配置文件：vi /home/es/logstash-7.6.2/config/logstash.yml

xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: logstash_system
xpack.monitoring.elasticsearch.password: ffcsict123
xpack.monitoring.elasticsearch.hosts: ["https://192.168.248.10:9200"]
xpack.monitoring.elasticsearch.ssl.certificate_authority: "/home/es/logstash-7.6.2/config/ca.crt"

修改配置文件：vi /home/es/logstash-7.6.2/config/logstash-sample.conf

output {
   elasticsearch {
    hosts => ["https://192.168.248.10:9200","https://192.168.248.11:9200","https://192.168.248.12:9200"]
    index => "testlog-%{+YYYY.MM.dd}"
    user => "elastic"
    password => "ffcsict123"
    ssl => true
    cacert => "/home/es/logstash-7.6.2/config/ca.crt"
   }
 }

啟動：nohup /home/es/logstash-7.6.2/bin/logstash -f /home/es/logstash-7.6.2/config/logstash-sample.conf &

五、配置filebeat

--------------------如果logstash不需要轉(zhuǎn)https，則可以忽略以下步驟-----------------

殺死logstash進程

將 logstash.key 轉(zhuǎn)換為 PKCS#8 格式

cd /home/es/logstash-7.6.2/config
openssl pkcs8 -in logstash.key -topk8 -nocrypt -out logstash.pkcs8.key

由于我們一個logstash服務，會有很多filebeat服務寫日志進來。如果將logstash改為https訪問，需要將所有涉及的filebeat都進行改配置。所以如果只是要求es改造為https，可以不改造logstash。如果需要改造，則修改配置文件：vi /home/es/logstash-7.6.2/config/logstash-sample.conf

input {
  beats {
    port => 5044
    ssl => true
    ssl_certificate_authorities => ["/home/es/logstash-7.6.2/config/ca.crt"]
    ssl_certificate => "/home/es/logstash-7.6.2/config/logstash.crt"
    ssl_key => "/home/es/logstash-7.6.2/config/logstash.pkcs8.key"
    ssl_verify_mode => "force_peer"
  }
}

啟動logstash：nohup /home/es/logstash-7.6.2/bin/logstash -f /home/es/logstash-7.6.2/config/logstash-sample.conf &
將filebeat證書放到/home/es/filebeat-7.6.2-linux-x86_64下：filebeat.crt、filebeat.crt、filebeat.key

配置filebeat：vi /home/es/filebeat-7.6.2-linux-x86_64/filebeat.yml

output.logstash:
  hosts: ["192.168.248.10:5044"]
  ssl.certificate_authorities: ["/home/es/filebeat-7.6.2-linux-x86_64/ca.crt"]
  ssl.certificate: "/home/es/filebeat-7.6.2-linux-x86_64/filebeat.crt"
  ssl.key: "/home/es/filebeat-7.6.2-linux-x86_64/filebeat.key"

啟動：nohup /home/es/filebeat-7.6.2-linux-x86_64/filebeat -e -c /home/es/filebeat-7.6.2-linux-x86_64/filebeat.yml &文章來源地址http://www.zghlxwxcb.cn/news/detail-697881.html

六、連接https es的java api

import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.config.RequestConfig;

import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.nio.client.HttpAsyncClientBuilder;
import org.apache.http.ssl.SSLContextBuilder;
import org.apache.http.ssl.SSLContexts;
import org.elasticsearch.action.admin.indices.alias.get.GetAliasesRequest;
import org.elasticsearch.client.*;
import org.elasticsearch.cluster.metadata.AliasMetadata;
import org.springframework.core.io.ClassPathResource;

import javax.net.ssl.SSLContext;
import java.io.IOException;
import java.io.InputStream;
import java.security.KeyStore;
import java.security.cert.Certificate;
import java.security.cert.CertificateFactory;
import java.util.*;
