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:
transport.tcp.compress: true http.max_content_length: 200mb
http.cors.enabled: true
http.cors.allow-origin: "*"
http.port: 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:
cluster.routing.allocation.node_concurrent_recoveries:
cluster.routing.allocation.node_initial_primaries_recoveries:
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 dilm - elastic_node3
127.0.0.1 dilm - elastic_node1
127.0.0.1 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。
5、配置kibana认证
elasticsearch.username: "kibana"
elasticsearch.password: ""
- 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:
transport.tcp.compress: true http.max_content_length: 200mb
http.cors.enabled: true
http.cors.allow-origin: "*"
http.port: 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:
cluster.routing.allocation.node_concurrent_recoveries:
cluster.routing.allocation.node_initial_primaries_recoveries: 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.
container_name: es01
environment:
- node.name=es01
- cluster.name=es-docker-cluster
- discovery.seed_hosts=192.168.43.128:
- cluster.initial_master_nodes=es01,192.168.43.128:
- 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: -
hard: -
volumes:
- ./mnt/data:/usr/share/elasticsearch/data
- ./mnt/logs:/usr/share/elasticsearch/logs
ports:
- :
- :
networks:
- elastic
cerebro:
image: lmenezes/cerebro:0.8.
container_name: cerebro
ports:
- "9000:9000"
command:
- -Dhosts..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.
container_name: es01
environment:
- node.name=es01
- cluster.name=es-docker-cluster
- discovery.seed_hosts=192.168.43.128:
- cluster.initial_master_nodes=es01,192.168.43.128:
- 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: -
hard: -
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:
- :
- :
networks:
- elastic
cerebro:
image: lmenezes/cerebro:0.8.
container_name: cerebro
ports:
- "9000:9000"
command:
- -Dhosts..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.</version>
</dependency> <dependency>
<groupId>org.elasticsearch.client</groupId>
