部署步骤

1.初始化es配置文件

    -- 拉取es镜像
    docker pull elasticsearch:7.2.0
    --创建挂载目录[data:存放索引数据，plugins:存放es插件]
    mkdir -p  /home/software/elasticsearch
    mkdir -p  /home/software/elasticsearch/config/data1
    mkdir -p  /home/software/elasticsearch/config/data2
    mkdir -p  /home/software/elasticsearch/config/data3
    mkdir -p  /home/software/elasticsearch/config/plugins1
    mkdir -p  /home/software/elasticsearch/config/plugins2
    mkdir -p  /home/software/elasticsearch/config/plugins3
    
    -- 设置执行权限
    chmod 777 /home/software/elasticsearch/config/data1 
    chmod 777 /home/software/elasticsearch/config/data2 
    chmod 777 /home/software/elasticsearch/config/data3 
    
    --data1/data2/data3 分别创建es.yml [network.publish_host:填写服务器ip]
    vim /home/software/elasticsearch/config/es1.yml
    ->>
        cluster.name: elasticsearch-cluster 
        cluster.initial_master_nodes : es-node1
        node.name: es-node1 
        network.bind_host: 0.0.0.0 
        network.publish_host: 192.168.100.200 
        http.port: 9201 
        transport.tcp.port: 9301
        http.cors.enabled: true

        discovery.zen.ping.unicast.hosts:  ["192.168.100.200:9301","192.168.100.200:9302","192.168.100.200:9303"] 
       
    vim /home/software/elasticsearch/config/es2.yml
    ->>
        cluster.name: elasticsearch-cluster 
        node.name: es-node2
        network.bind_host: 0.0.0.0 
        network.publish_host: 192.168.100.200 
        http.port: 9202
        transport.tcp.port: 9302 
        http.cors.enabled: true 
        http.cors.allow-origin: "*" 
        node.master: true 
        node.data: true  
        discovery.zen.ping.unicast.hosts:  ["192.168.100.200:9301","192.168.100.200:9302","192.168.100.200:9303"] 

    vim /home/software/elasticsearch/config/es3.yml
    ->>
        cluster.name: elasticsearch-cluster 
        node.name: es-node3
        network.bind_host: 0.0.0.0 
        network.publish_host: 192.168.100.200

调高JVM线程数限制数量

vim /etc/sysctl.conf
->>
	vm.max_map_count=262144 
	
# 刷新配置
sysctl -p

2.服务部署

es集群部署


	
	# 服务1
     docker run -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \
        -d -p 9201:9201 -p 9301:9301 \
        -e ES_MIN_MEM=128m \
        -e ES_MAX_MEM=4096m \
        -v /home/software/elasticsearch/config/es1.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
        -v /home/software/elasticsearch/config/data1/:/usr/share/elasticsearch/data/ \
        -v /home/software/elasticsearch/config/plugins1/:/usr/share/elasticsearch/plugins  \
        --restart=always \
        --name es01 \
        elasticsearch:7.2.0
    # 服务2
     docker run -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \
        -d -p 9202:9202 -p 9302:9302 \
        -e ES_MIN_MEM=128m \
        -e ES_MAX_MEM=4096m \
        -v /home/software/elasticsearch/config/es2.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
        -v /home/software/elasticsearch/config/data2/:/usr/share/elasticsearch/data/ \
        -v /home/software/elasticsearch/config/plugins2/:/usr/share/elasticsearch/plugins  \
        --restart=always \
        --name es02 \
        elasticsearch:7.2.0
     # 服务3
     docker run -e ES_JAVA_OPTS="-Xms2048m -Xmx2048m" \
        -d -p 9203:9203 -p 9303:9303 \
        -e ES_MIN_MEM=128m \
        -e ES_MAX_MEM=4096m \
        -v /home/software/elasticsearch/config/es3.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
        -v /home/software/elasticsearch/config/data3/:/usr/share/elasticsearch/data/ \
        -v /home/software/elasticsearch/config/plugins3/:/usr/share/elasticsearch/plugins  \
        --restart=always \
        --name es03 \
        elasticsearch:7.2.0
        
	# 防火墙设置	
    firewall-cmd --add-port=9301/tcp
    firewall-cmd --add-port=9302/tcp 
    firewall-cmd --add-port=9303/tcp
    firewall-cmd --add-port=9200/tcp
    firewall-cmd --add-port=9201/tcp 
    firewall-cmd --add-port=9202/tcp 
    firewall-cmd --add-port=9203/tcp
    firewall-cmd --complete-reload

确认集群配置

curl http://127.0.0.1:9201/_cat/nodes?pretty

3.IK分词器安装

https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.2.0/elasticsearch-analysis-ik-7.2.0.zip下载下来放到/home/software/elasticsearch/config/plugins1/中然后复制到 plugins2 、plugins3

重启三个es节点

5.ES负载均衡

nginx配置es负载均衡

修改nginx配置文件文章来源地址https://www.toymoban.com/news/detail-522923.html

#修改nginx配置文件
vim /home/software/nginx/conf.d/default.conf

->>
# 配置上游服务器集群信息
upstream es-cluster {
        server 192.168.100.200:9201;
        server 192.168.100.200:9202;
        server 192.168.100.200:9203;
  keepalive 1000;
}

# 配置代理服务器信息
server {
  listen 9200;
  server_name localhost;

  location / {
    proxy_http_version  1.1;
    proxy_set_header    Connection "";
    proxy_pass http://es-cluster;
  }

  location /nginx-status {
      stub_status on;
  }
}
