-
- 一、生成相关证书
- 二、配置elasticSearh
- 三、配置kibana
- 四、配置logstash
- 五、配置filebeat
- 六、连接https es的java api
一、生成相关证书
ps：主节点操作
-
切换用户：su es
-
进入目录：cd /home/es/elasticsearch-7.6.2
-
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" -
生成证书：/home/es/elasticsearch-7.6.2/bin/elasticsearch-certutil cert ca --pem --in instances.yml --out certs.zip
-
解压得到各个证书：unzip certs.zip
二、配置elasticSearh
ps：三个节点
-
切换用户：su es
-
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
-
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.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用户拷贝的，记得赋权：chown -R es:es /home/es
-
启动
cd /home/es/elasticsearch-7.6.2/bin nohup /home/es/elasticsearch-7.6.2/bin/elasticsearch & -
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
-
将kibana证书放到/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 # 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" -
如果是用root用户拷贝的，记得赋权：chown -R es:es /home/es
-
启动：nohup /home/es/kibana-7.6.2-linux-x86_64/bin/kibana &
-
访问：https://192.168.248.10:5601
四、配置logstash
-
将logstash证书放到/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" } } -
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-----------------
-
杀死logstash进程
-
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 -
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 => 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" } } -
启动logstash：nohup /home/es/logstash-7.6.2/bin/logstash -f /home/es/logstash-7.6.2/config/logstash-sample.conf &
-
将filebeat证书放到/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" -
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
