    name=Elasticsearch repository for 6.x packages
    baseurl=https://artifacts.elastic.co/packages/6.x/yum
    gpgcheck=1
    gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
    enabled=1
    autorefresh=1
    type=rpm-md
    # 安装
    yum install elasticsearch
    yum install --enablerepo=elasticsearch elasticsearch
    
    [elasticsearch]

  2. 开机自启动

    /bin/systemctl daemon-reload
    /bin/systemctl enable elasticsearch.service
    
  3. 修改配置
    vim /etc/elasticsearch/elasticsearch.yml
    # 修改配置
    network.host: 0.0.0.0
    http.port: 9200
    # 保存退出,重启
    service elasticsearch restart
    # 或
    systemctl restart elasticsearch.service
    
  4. 安装ik分词插件
