Spring Boot连接ES，spring-boot-starter-data-elasticsearch。必须为集群方式！否则报错！

报错：

None of the configured nodes are available

安装步骤: 进入 cd /home

1.mkdir -p es/config2.cd es3.mkdir data14.mkdir data25.mkdir data36.firewall-cmd --add-port=9300/tcp7.firewall-cmd --add-port=9301/tcp8.mkdir plugins1
9.mkdir plugins2

步骤解析：

1. 目录文件：是用来挂载用的，同步配置文件。容器的和外部的同步。

3. 4. 5. 表示两个es外部挂载目录

6. 7. 防火墙设置

8. 9 存放分词插件

es1.yml

cluster.name: elasticsearch-cluster
node.name: es-node1
network.bind_host: 0.0.0.0
network.publish_host: 192.168.91.66
http.port: 9200
transport.tcp.port: 9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.91.66:9300","192.168.91.66:9301"]
discovery.zen.minimum_master_nodes: 1

es2.yml:

cluster.name: elasticsearch-cluster
node.name: es-node2
network.bind_host: 0.0.0.0
network.publish_host: 192.168.91.66
http.port: 9201
transport.tcp.port: 9301
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["192.168.91.66:9300","192.168.91.66:9301"]
discovery.zen.minimum_master_nodes: 1

步骤解析:

node.name: es-node1 集群中保证唯一

discovery.zen.minimum_master_nodes: 1 master节点有1个伪集群的方式,两个配置文件这里是不一样的: 通过端口号区别不同的ES

http.port: 9200
transport.tcp.port: 9300将上述两个配置文件放入到：es/config

启动:

容器1：

便于看：

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 -p 5601:5601

-v /home/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml

-v /home/es/plugins1:/usr/share/elasticsearch/plugins

-v /home/es/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch

应该这样运行: 格式化

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 -p 5601:5601 -v /home/es/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /home/es/plugins1:/usr/share/elasticsearch/plugins -v /home/es/data1:/usr/share/elasticsearch/data --name ES01 elasticsearch

解析：设置jvm内存端口号挂载

容器2：

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301

-v /home/es/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml

-v /home/es/plugins2:/usr/share/elasticsearch/plugins

-v /home/es/data2:/usr/share/elasticsearch/data --name ES02 elasticsearch

格式化指令：

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9201:9201 -p 9301:9301 -v /home/es/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /home/es/plugins2:/usr/share/elasticsearch/plugins -v /home/es/data2:/usr/share/elasticsearch/data --name ES02 elasticsearch
