centos安装Elasticsearch

一、yum安装：

　　1. 在/etc/yum.repos.d/目录创建文件elasticsearch.repo

　　2. 添加以下内容

[elasticsearch-6.x]
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

　　3. 执行yum命令：sudo yum install elasticsearch -y

　　4. 设置开机启动：sudo chkconfig --add elasticsearch

　　5. 启动：sudo -i service elasticsearch start

　　　　-- 关闭 sudo -i service elasticsearch stop

　　　　-- 重启 sudo -i service elasticsearch restart

二、测试项目是否运行

　　-- curl -X GET 'http://localhost:9200/?pretty'　　

　　返回结果类似如下显示：

{
  "name" : "Cp8oag6",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
  "version" : {
    "number" : "6.4.3",
    "build_flavor" : "default",
    "build_type" : "zip",
    "build_hash" : "f27399d",
    "build_date" : "2016-03-30T09:51:41.449Z",
    "build_snapshot" : false,
    "lucene_version" : "7.4.0",
    "minimum_wire_compatibility_version" : "1.2.3",
    "minimum_index_compatibility_version" : "1.2.3"
  },
  "tagline" : "You Know, for Search"
}　

三、更改配置，增加远程访问

　　-- 配置文件目录：/etc/elasticsearch/

　　-- elasticsearch.yml文件增加如下属性：

　　　　- network.host: 0.0.0.0
