Elasticsearch7.6 集群部署、集群认证及使用、数据备份

window 环境部署集群

注意:window下载解压elasticsearch一定需要解压多次。例如搭建的3节点的,需要解压3次,防止生成 cluster UUID 一致导致只能看到一个节点

1、elasticsearch.yml配置:

node.name区别:elastic_node1、 elastic_node2、 elastic_node3

cluster.name: elastic_cluster

node.name: elastic_node1

node.master: true
node.data: true

#path.data: /usr/local/elastic_node1/data
#path.logs: /usr/local/elastic_node1/logs

bootstrap.memory_lock: true

network.host: 0.0.0.0
network.tcp.no_delay: true
network.tcp.keep_alive: true
network.tcp.reuse_address: true
network.tcp.send_buffer_size: 256mb
network.tcp.receive_buffer_size: 256mb

transport.tcp.port: 9301
transport.tcp.compress: true

http.max_content_length: 200mb
http.cors.enabled: true
http.cors.allow-origin: "*"
http.port: 9201

discovery.seed_hosts: ["127.0.0.1:9301","127.0.0.1:9302","127.0.0.1:9303"]
cluster.initial_master_nodes: ["127.0.0.1:9301","127.0.0.1:9302","127.0.0.1:9303"]
cluster.fault_detection.leader_check.interval: 15s
discovery.cluster_formation_warning_timeout: 30s
cluster.join.timeout: 30s
cluster.publish.timeout: 90s
cluster.routing.allocation.cluster_concurrent_rebalance: 16
cluster.routing.allocation.node_concurrent_recoveries: 16
cluster.routing.allocation.node_initial_primaries_recoveries: 16

2、依次运行生成集群

浏览器打开:http://127.0.0.1:9201/_cat/nodes?v

ip        heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
127.0.0.1           19          64  37                          dilm      -      elastic_node3
127.0.0.1           13          64  47                          dilm      -      elastic_node1
127.0.0.1           22          64  50                          dilm      *      elastic_node2

3、生成证书

es集群通过证书来安全的组成集群

  • 运行
    bin/elasticsearch-certutil cert
注意: 密码后面需要单独设置,这里是集群安全认证,建议密码不设置,成功后生成的证书默认在es的config目录里面 elastic-certificates.p12;分别copy一份到其他节点的config里面(默认目录)

在elasticsearch.yml配置添加

xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12

4、给认证的集群创建用户密码

bin/elasticsearch-setup-passwords interactive
  • elastic 账号:拥有 superuser 角色,是内置的超级用户。
  • kibana 账号:拥有 kibana_system 角色,用户 kibana 用来连接 elasticsearch 并与之通信。Kibana 服务器以该用户身份提交请求以访问集群监视 API 和 .kibana 索引。不能访问 index。
  • logstash_system 账号:拥有 logstash_system 角色。用户 Logstash 在 Elasticsearch 中存储监控信息时使用。
  • beats_system账号:拥有 beats_system 角色。用户 Beats 在 Elasticsearch 中存储监控信息时使用。
# elastic
# apm_system
# kibana
# logstash_system
# beats_system
# remote_monitoring_user

5、配置kibana认证

elasticsearch.username: "kibana"
elasticsearch.password: "123456"
  • 完整的elasticsearch.yml配置,注意不同节点node.name区别
cluster.name: elastic_cluster
node.name: elastic_node1
node.master: true
node.data: true

#path.data: /usr/local/elastic_node1/data
#path.logs: /usr/local/elastic_node1/logs

bootstrap.memory_lock: true

network.host: 0.0.0.0
network.tcp.no_delay: true
network.tcp.keep_alive: true
network.tcp.reuse_address: true
network.tcp.send_buffer_size: 256mb
network.tcp.receive_buffer_size: 256mb

transport.tcp.port: 9302
transport.tcp.compress: true

http.max_content_length: 200mb
http.cors.enabled: true
http.cors.allow-origin: "*"
http.port: 9202

discovery.seed_hosts: ["127.0.0.1:9301","127.0.0.1:9302","127.0.0.1:9303"]
cluster.initial_master_nodes: ["127.0.0.1:9301","127.0.0.1:9302","127.0.0.1:9303"]
cluster.fault_detection.leader_check.interval: 15s
discovery.cluster_formation_warning_timeout: 30s
cluster.join.timeout: 30s
cluster.publish.timeout: 90s
cluster.routing.allocation.cluster_concurrent_rebalance: 16
cluster.routing.allocation.node_concurrent_recoveries: 16
cluster.routing.allocation.node_initial_primaries_recoveries: 16

xpack.security.enabled: true
xpack.license.self_generated.type: basic
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12

centos(docker-compose) 环境部署集群

1、docker-compose.yml配置

version: '2.2'
services:
  es01:
    image: elasticsearch:7.6.0
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=192.168.43.128:9300
      - cluster.initial_master_nodes=es01,192.168.43.128:9300
      - cluster.fault_detection.leader_check.interval=15s
      - bootstrap.memory_lock=true
      - http.cors.enabled=true
      - http.cors.allow-origin=*
      - network.host=0.0.0.0
      - network.publish_host=192.168.43.129
      - xpack.security.enabled=true
      - xpack.security.transport.ssl.enabled=true
      - "ES_JAVA_OPTS=-Xms256m -Xmx256m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - ./mnt/data:/usr/share/elasticsearch/data
      - ./mnt/logs:/usr/share/elasticsearch/logs
    ports:
      - 9200:9200
      - 9300:9300
    networks:
      - elastic
  cerebro:
    image: lmenezes/cerebro:0.8.3
    container_name: cerebro
    ports:
      - "9000:9000"
    command:
      - -Dhosts.0.host=http://es01:9200
    networks:
      - elastic
volumes:
  mnt:
    driver: local

networks:
  elastic:
    driver: bridge

权限问题执行 chmod -R 777 mnt/*

2、生成证书文件创建密码

  • 进入容器 docker exec -it 5144d3b1dd56 /bin/bash
  • 生成证书 bin/elasticsearch-certutil cert
  • 复制证书并cp到其他节点 docker cp 09f57b6067e0:/usr/share/elasticsearch/elastic-certificates.p12 .

3、修改配置&&动态添加测试

version: '2.2'
services:
  es01:
    image: elasticsearch:7.6.0
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=192.168.43.128:9300
      - cluster.initial_master_nodes=es01,192.168.43.128:9300
      - cluster.fault_detection.leader_check.interval=15s
      - bootstrap.memory_lock=true
      - http.cors.enabled=true
      - http.cors.allow-origin=*
      - network.host=0.0.0.0
      - network.publish_host=192.168.43.129
      - xpack.security.enabled=true
      - xpack.security.transport.ssl.enabled=true
      - xpack.license.self_generated.type=basic
      - xpack.security.transport.ssl.verification_mode=certificate
      - xpack.security.transport.ssl.keystore.path=elastic-certificates.p12
      - xpack.security.transport.ssl.truststore.path=elastic-certificates.p12
      - "ES_JAVA_OPTS=-Xms256m -Xmx256m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - ./mnt/data:/usr/share/elasticsearch/data
      - ./mnt/logs:/usr/share/elasticsearch/logs
      - ./mnt/elastic-certificates.p12:/usr/share/elasticsearch/config/elastic-certificates.p12
    ports:
      - 9200:9200
      - 9300:9300
    networks:
      - elastic
  cerebro:
    image: lmenezes/cerebro:0.8.3
    container_name: cerebro
    ports:
      - "9000:9000"
    command:
      - -Dhosts.0.host=http://es01:9200
    networks:
      - elastic
volumes:
  mnt:
    driver: local

networks:
  elastic:
    driver: bridge

注意证书的位置,给权限 chmod -R 777 mnt/*

  • 设置密码(建议进入主节点容器中) bin/elasticsearch-setup-passwords interactive -u 'http://es01:9200'
  • 通用配置与window类似

springboot使用测试

1、引入pom

  <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>7.6.0</version>
        </dependency>

        <dependency>

ElasticSearch 6.x数据迁移ElasticSearch7.4

  1. 安装nodejs
    yum install nodejs -y --registry=https://registry.npm.taobao.org
  2. 安装elasticdump 
    npm install elasticdump -g
  3. 升级nodejs
    npm install -g n
    n latest

     

  4. mapping拷贝(建议手动拷贝)

    elasticdump --input=http://127.0.0.1:9200/index(修改为真实的索引名称) --output=http://10.0.1.236:9200/index --type=mapping(修改为真实的索引名称与需要导入的IP)
  5. data拷贝
    # 创建认证文件
    cat > authFile <<EOF
    user=elastic
    password=xxxxxx
    EOF
    
    # dump数据
    elasticdump --input=http://192.168.0.110:9200/test-20200510 --output=http://192.168.0.215:9201/test-20200510 --type=data --limit=100000 --httpAuthFile=authFile
