ES集群效果

     

     检查集群状况

     

  

 集群搭建步骤

Dockerfile

#!/bin/bash

#change es config

# start es cluster
echo "start es cluster........"
su - elasticsearch -c /elasticsearch/bin/elasticsearch

start-escluster.sh

   

     启动pod的时候传递根据需要创建pod的数量传递对应的环境变量参数

   

   把master的pod映射到主机进行访问

       1.创建一个DNS记录

       

       

        2.通过主机浏览器访问ES集群

         

ES集群证书生成

      1.添加卷映射

       

 

     2.生成证书和密码

            ./elasticsearch-certutil cert --ip 192.168.30.106 --out /elasticsearch/config/certs/elastic-stack-ca.zip --pem

           ./elasticsearch-setup-passwords interactive --batch --url https://192.168.30.106:39200

           

 

      3.修改elastic的配置yml文件,添加certs证书认证

cluster.name: "taishi-escluster"
node.name: node1
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300
bootstrap.memory_lock: false
cluster.initial_master_nodes: [ "node1" ]
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: false
discovery.seed_hosts: ["127.0.0.1:9300"]
xpack.license.self_generated.type: basic
xpack.security.enabled: true
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.key: /elasticsearch/config/certs/instance/instance.key
xpack.security.http.ssl.certificate: /elasticsearch/config/certs/instance/instance.crt
xpack.security.http.ssl.certificate_authorities: /elasticsearch/config/certs/ca/ca.crt
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.key: /elasticsearch/config/certs/instance/instance.key
xpack.security.transport.ssl.certificate: /elasticsearch/config/certs/instance/instance.crt
xpack.security.transport.ssl.certificate_authorities: /elasticsearch/config/certs/ca/ca.crt

elasticsearch.yml

      4.验证https登录es

      

 

    5.集群https访问成功
