**相关配置参数**

**cluster.name：**设置集群的名称，默认为elasticsearch

**node.name：**设置节点的名称，同一集群中节点的名称不能重复

**node.master：**设置节点为候选主节点，主节点只能在候选主节点中选举，**默认为true**

**node.data：**为true是表示节点能存储数据，false节点不能存储数据，**默认为true**

**cluster.initial\_master\_nodes：**设置集群的初始主节点名称，**形式：\["node-1","node-2","node-3"\]**

**discovery.type：**设置发现类型，单机使用single-node，集群zen、legacy-zen

**index.number\_of\_shards：**设置主分片的个数，默认为5

**index.number\_of\_replicas：**设置副本分片的个数，默认为1

**path.conf：**设置配置文件的路径

**path.data：**设置索引数据的存储路径

**path.logs：**设置日志数据路径

**path.plugins：**设置插件的存放路径

**bootstrap.mlockall：**设置为true可锁定内存，避免与磁盘发生内存交换

**network****.bind\_host：**节点绑定的ip地址，默认为0.0.0.0

**network.publish\_host：**节点与其他节点交互地址，如果不设置会自动判断

**network.host：**同时设置network.bind\_host、network.publish\_host

**http.port：**http访问端口，默认为9200

**transport.tcp.port：**节点交互端口

**transport.tcp.compress：**节点传输的数据是否压缩

**discovery.zen.minimum\_master\_nodes：**设置选主时最少需要参与的候选主节点数，默认为1

**discovery.zen.ping.timeout：**设置节点通信的超时时间，默认为3s，网络环境较差时，可适当调大该值，避免误判

**discovery.seed\_hosts：**设置master节点初始列表，**形式为：\["host1","host2","host3"\]**

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**单机搭建：常用于测试，生产环境中应用集群**

**配置文件elasticsearch.yml**

http.host: 0.0.0.0
    
    discovery.type: single-node
    discovery.seed_hosts: [172.18.0.2]

**创建elasticsearch容器**

docker run -it -d --net fixed --ip 172.18.0.2 -p 9200:9200 -p 9300:9300 \
    -v /usr/elasticsearch/single/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
    --name es-single elasticsearch:7.5.1

**集群搭建**

**配置文件elasticsearch.yml**

http.host: 0.0.0.0
    network.host: 0.0.0.0
    
    node.name: node-1     //不同的节点node.name需设置为不同
    
    http.cors.enabled: true
    http.cors.alllow-origin: "*"
    
    cluster.initial_master_nodes: ["node-1","node-2","node-3"]
    
    discovery.seed_hosts: [172.18.0.10,172.18.0.11,172.18.0.12]
    discovery.zen.minimum_master_nodes: 2

**创建集群**

docker run -it -d --net fixed --ip 172.18.0.10 -p 9201:9200 -p 9301:9300 -v /usr/elasticsearch/cluster/node-1/data:/usr/share/elasticsearch/data -v /usr/elasticsearch/cluster/node-1/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml --name es-node-1 elasticsearch:7.5.1
    docker run -it -d --net fixed --ip 172.18.0.11 -p 9202:9200 -p 9302:9300 -v /usr/elasticsearch/cluster/node-2/data:/usr/share/elasticsearch/data -v /usr/elasticsearch/cluster/node-2/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml --name es-node-2 elasticsearch:7.5.1
    docker run -it -d --net fixed --ip 172.18.0.12 -p 9203:9200 -p 9303:9300 -v /usr/elasticsearch/cluster/node-3/data:/usr/share/elasticsearch/data -v /usr/elasticsearch/cluster/node-3/conf/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml --name es-node-3 elasticsearch:7.5.1
