Docker搭建ES集群

男娘i 2021-10-23 23:18 453阅读 0赞

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/config
    
    2.cd es
    
    3.mkdir data1
    
    4.mkdir data2
    
    5.mkdir data3
    
    6.firewall-cmd --add-port=9300/tcp
    
    7.firewall-cmd --add-port=9301/tcp
    
    8.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: 192.168.212.252
    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: 192.168.212.252
    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

*注：如果ELK选的6.X版本的，那么需将data1 data2 data3 开启777权限=> chmod 777 data1 data2 data3*
