每一台服务器都需要操作。

在/opt下创建es  把下载好后把安装包放入
    
    cd /opt
    #创建es目录
    mkdir es
    cd es 
    #下载安装包
    wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.12.0-linux-x86_64.tar.gz
    #解压
    tar -vxf elasticsearch-7.12.0-linux-x86_64.tar.gz
    
    #修改解压后的文件名为 elasticsearch-a,(为了方便区分根据节点名)
    
    
    
    mv elasticsearch-7.4.0 elasticsearch-1
    
    # 创建数据存储目录
    mkdir -p /opt/es/elasticsearch-a/data
    # 创建日志存储目录
    mkdir  -p /opt/es/elasticsearch-a/logs
    
    #注：这里为了区分是es的多个节点，
    #第1台的目录文件夹为 elasticsearch-1
    #第2台的目录文件夹为 elasticsearch-2
    #第3台的目录文件夹为 elasticsearch-3

## 节点node-1配置 ##

进入到es安装目录下的config文件夹中，修改elasticsearch.yml 文件

# ======================== Elasticsearch Configuration =========================
    #
    # NOTE: Elasticsearch comes with reasonable defaults for most settings.
    #       Before you set out to tweak and tune the configuration, make sure you
    #       understand what are you trying to accomplish and the consequences.
    #
    # The primary way of configuring a node is via this file. This template lists
    # the most important settings you may want to configure for a production cluster.
    #
    # Please consult the documentation for further information on configuration options:
    # https://www.elastic.co/guide/en/elasticsearch/reference/index.html
    #
    # ---------------------------------- Cluster -----------------------------------
    #
    # Use a descriptive name for your cluster:
    #
    #配置es的集群名称，同一个集群中的多个节点使用相同的标识
    #如果在同一网段下有多个集群，就可以用这个属性来区分不同的集群。
    cluster.name: my-cluster
    #
    # ------------------------------------ Node ------------------------------------
    #
    # Use a descriptive name for the node:
    #
    #节点名称
    node.name: node-1
    #是不是有资格竞选主节点
    node.master: true
    #
    # Add custom attributes to the node:
    #
    #node.attr.rack: r1
    #
    # ----------------------------------- Paths ------------------------------------
    #
    # Path to directory where to store the data (separate multiple locations by comma):
    #
    #数据存储路径
    path.data: /opt/es/data
    #
    # Path to log files:
    #
    #日志存储路径
    path.logs: /opt/es/logs
    #
    # ----------------------------------- Memory -----------------------------------
    #
    # Lock the memory on startup:
    #
    
    #ES默认开启了内存地址锁定，为了避免内存交换提高性能。但是Centos6不支持SecComp功能，启动会报错，所以需要将其设置为false
    #bootstrap.memory_lock: true
    #
    # Make sure that the heap size is set to about half the memory available
    # on the system and that the owner of the process is allowed to use this
    # limit.
    #
    # Elasticsearch performs poorly when the system is swapping the memory.
    #
    # ---------------------------------- Network -----------------------------------
    #
    # By default Elasticsearch is only accessible on localhost. Set a different
    # address here to expose this node on the network:
    #
    #节点所绑定的IP地址，并且该节点会被通知到集群中的其他节点
    #通过指定相同网段的其他节点会加入该集群中 0.0.0.0任意IP都可以访问elasticsearch
    network.host: 10.10.164.1
    bootstrap.system_call_filter: false 
    #
    # By default Elasticsearch listens for HTTP traffic on the first free port it
    # finds starting at 9200. Set a specific HTTP port here:
    #
    #作为数据节点
    node.data: true
    #对外提供服务的http端口，默认为9200
    http.port: 9200
    
    # 是否支持跨域
    http.cors.enabled: true
    
    # *表示支持所有域名
    http.cors.allow-origin: "*"
    
    #内部节点之间沟通端口
    transport.tcp.port: 9300
    #设置是否压缩TCP传输时的数据，默认为false
    transport.tcp.compress: true
    
    #network.publish_host:10.10.164.1
    cluster.routing.allocation.disk.threshold_enabled: false
    #
    # For more information, consult the network module documentation.
    #
    # --------------------------------- Discovery ----------------------------------
    #
    # Pass an initial list of hosts to perform discovery when this node is started:
    # The default list of hosts is ["127.0.0.1", "[::1]"]
    #
    
    #es7.x 之后新增的配置，写入候选主节点的设备地址，在开启服务后可以被选为主节点
    discovery.seed_hosts: ["10.10.164.1:9300", "10.10.164.2:9300","10.10.164.3:9300"]
    
    #
    # Bootstrap the cluster using an initial set of master-eligible nodes:
    #
    
    #es7.x 之后新增的配置，初始化一个新的集群时需要此配置来选举master
    cluster.initial_master_nodes: ["node-1", "node-2","node-3"]
    
    #
    # For more information, consult the discovery and cluster formation module documentation.
    #
    # ---------------------------------- Various -----------------------------------
    #
    # Require explicit names when deleting indices:
    #
    #action.destructive_requires_name: true

groupadd elsearch
    useradd elsearch -g elsearch -p elasticsearch            #useradd [user name] -g [group name] -p [password]
    chown -R elsearch:elsearch  elasticsearch               #chown -R [user name:group name] 该用户所分配有权限的目录
    su elsearch #切换账户
    cd elasticsearch/bin #进入你的elasticsearch目录下的bin目录
    ./elasticsearch 
    
    ElasticSearch后台启动命令
    ./elasticsearch -d
    
    查看后台命令是否启动成功
    ps aux|grep elasticsearch

同启动1节点一致，分别再次启动 2节点、3节点
