**elasticsearch 安装配置**

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.4.3.rpm 
       rpm --install elasticsearch-5.4.3.rpm

**配置文件**  
配置文件修改的部分

vim /etc/elasticsearch/elasticsearch.yml 
             cluster.name: paasdev-es
             node.name: es-node2
             path.data: /elasticsearch/data
             network.host: ip
             http.port: 9200
             discovery.zen.ping.unicast.hosts: ["node01Ip:9300", "node02Ip:9300"]
             discovery.zen.minimum_master_nodes: 2

**安装基础环境**

#添加yum源
    cat >> /etc/yum.repos.d/CentOS-es.repo << END
    [elasticsearch-5.x]
    name=Elasticsearch repository for 5.x packages
    baseurl=https://artifacts.elastic.co/packages/5.x/yum
    gpgcheck=1
    gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
    enabled=1
    autorefresh=1
    type=rpm-md
    END
    #加载yum源
    yum makecache
    #安装elasticsearch与JDK(JDK使用oracle版本，需要到官网自行下载到本地)
    yum install jdk-8u144-linux-x64 elasticsearch\*5.4\* -y
    #配置java环境
    echo "JAVA_HOME=/usr/bin/java" > /etc/profile.d/java.sh
    . /etc/profile.d/java.sh
    echo $JAVA_HOME

**配置elasticsearch**

vi /etc/elasticsearch/elasticsearch.yml
        #集群名称，所有节点的集群名称需要一致
        cluster.name: enpass-es
        #节点2名为node-2,节点3名为node3
        node.name: node-1
        #数据存放目录
        path.data: /elasticsearch/data
        #日志存放目录
        path.logs: /var/log/elasticsearch/logs
        #节点IP(节点2IP地址192.168.1.43，节点IP地址192.168.1.42)
        network.host: 192.168.1.44
        #使用9200端口对外提供服务
        http.port: 9200
        #其他节点IP地址，(9300是节点内选举所用的端口)
        discovery.zen.ping.unicast.hosts: ["node01:9300", "node02:9300","node03:9300"]
        #参加选举的几点数量(节点数/2+1，向下取整)
        discovery.zen.minimum_master_nodes: 2
    
    #创建es对应的目录并授权
    mkdir -p  /elasticsearch/data
    mkdir -p /var/log/elasticsearch/logs
    chown elasticsearch:elasticsearch -R /elasticsearch
    chown elasticsearch:elasticsearch -R /var/log/elasticsearch
    
    #启动服务
    systemctl daemon-reload
    systemctl enable elasticsearch.service 
    systemctl start elasticsearch.service
