一、生成相关证书

ps：主节点操作

1. 切换用户：su es

2. 进入目录：cd /home/es/elasticsearch-7.6.2

3. 创建文件：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"   
   

4. 生成证书：/home/es/elasticsearch-7.6.2/bin/elasticsearch-certutil cert ca --pem --in instances.yml --out certs.zip

5. 解压得到各个证书：unzip certs.zip

二、配置elasticSearh

ps：三个节点

1. 切换用户：su es

2. 将解压得到的三个文件夹文件拷贝到各个节点的/home/es/elasticsearch-7.6.2/config下，如master节点：ca.crt、master.crt、master.key

3. 三个节点配置，末尾添加配置：vi /home/es/elasticsearch-7.6.2/config/elasticsearch.yml
   ps1：根据名字配置master和slave1和slave2
   ps2：如果之前配置过密码，需要将密码的配置先移除

   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.crtxpack.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"]
   

4. 如果是用root用户拷贝的，记得赋权：chown -R es:es /home/es

5. 启动

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

6. 设置密码：/home/es/elasticsearch-7.6.2/bin/elasticsearch-setup-passwords interactive

   ps1：可以统一设置一个密码ffcsict123

   ps2：如果已经设置过密码了，可以忽略。或者也可以删除es的 .security-7 索引，重新执行设置密码的操作也可以

三、配置kibana

1. 将kibana证书放到/home/es/kibana-7.6.2-linux-x86_64/config下：kibana.crt、ca.crt、kibana.key

2. 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
   # 这三个路径写成相对路径会被错，写绝对路径才行，不知道为啥
   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"
   

3. 如果是用root用户拷贝的，记得赋权：chown -R es:es /home/es

4. 启动：nohup /home/es/kibana-7.6.2-linux-x86_64/bin/kibana &

5. 访问：https://192.168.248.10:5601
   

四、配置logstash

1. 将logstash证书放到/home/es/logstash-7.6.2/config下：logstash.crt、ca.crt、logstash.key

2. 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"
   

3. 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 => truecacert => "/home/es/logstash-7.6.2/config/ca.crt"}}
   

4. 启动：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不需要转https，则可以忽略以下步骤-----------------

1. 杀死logstash进程

2. 将 logstash.key 转换为 PKCS#8 格式

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

3. 由于我们一个logstash服务，会有很多filebeat服务写日志进来。如果将logstash改为https访问，需要将所有涉及的filebeat都进行改配置。所以如果只是要求es改造为https，可以不改造logstash。如果需要改造，则修改配置文件：vi /home/es/logstash-7.6.2/config/logstash-sample.conf

   input {beats {port => 5044ssl => truessl_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"}
   }
   

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

5. 将filebeat证书放到/home/es/filebeat-7.6.2-linux-x86_64下：filebeat.crt、filebeat.crt、filebeat.key

6. 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"
   

7. 启动：nohup /home/es/filebeat-7.6.2-linux-x86_64/filebeat -e -c /home/es/filebeat-7.6.2-linux-x86_64/filebeat.yml &

六、连接https es的java api
