1.配置dockercompose配置文件
version: '2'
services:
elasticsearch:
image: es/elasticsearch:7.7
container_name: es1
restart: always
dns_search: .
environment:
- bootstrap.memory_lock=true
- "ES_JAVA_OPTS=-Xms256m -Xmx256m"
ulimits:
memlock:
soft: -1
hard: -1
volumes:# data索引数据存储路径,logs日志输出,config配置
- /etc/timezone:/etc/timezone
- /etc/localtime:/etc/localtime
- ./es/data:/usr/share/elasticsearch/data
- ./es/logs:/usr/share/elasticsearch/logs
- ./elasticsearch/config:/usr/share/elasticsearch/config
ports:
- 9200:9200
- 9300:9300
external_links:
- es2 #同一机器下容器名称(为防止同一机器下docker容器之间不能通过ip进行互通)
- es3
tty: true
networks:
default:
external:
name: esnetwork #同一机器下,所有节点需要在同一网络下
2.eLasticSearch配置文件修改
cluster.name: es-cluster
node.name: es-node1
network.bind_host: 0.0.0.0
network.publish_host: 本机ip地址
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
##一下五行为配置X-pack安全
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
##指定证书路径
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
##是否参与master节点选举
node.master: true
##是否存储数据
node.data: true
#discovery.seed_hosts: ["elasticsearch2:10293","elasticsearch1:10193"]
#cluster.initial_master_nodes: ["es-node0","es-node1","es-node2"]
## 指定该集群下所有节点及端口(同一机器下可以用容器名称代替机器ip(前提是需要在dockerCompose配置中添加该节点的容器名))
discovery.seed_hosts: ["141.3.186.01:9301","es2:9302","es3:9303"]
##参与master节点选举的节点名称集合
cluster.initial_master_nodes: ["es-node1","es-node2","es-node3"]
3.其他节点可依照此配置统一配置,需注意:集群名称需一致,容器名称、节点名称、ip地址、端口号等不同。
配置完成后统一启动 docker-compose启动命令:
- docker-compose up -d #启动
- docker-compose restart #重启
可通过访问如下路径查看是否搭建成功:
http://141.3.186.01:9200/_cat/nodes?v&pretty
如图显示所有节点说明配置成功了
4.遇到问题
1.如果集群缺少几点(显示节点不全)
解决方法:关闭所有节点,删除所有节点的logs下的日志文件,然后重启所有节点。(可多试几次)
