安装使用 Elasticsearch 两种方法：

方法1 手动安装 Elasticsearch

安装到ubuntu

Elasticsearch与Logstash需要Java作为运行环境

安装Java 8

将甲骨文Java PPA添加至apt：

代码语言：javascript复制
sudo add-apt-repository -y ppa:webupd8team/java

更新apt软件包数据库：

代码语言：javascript复制
sudo apt-get update

安装甲骨文Java 8的最新稳定版本，命令如下（在弹出的许可协议中点击接受）：

代码语言：javascript复制
sudo apt-get -y install oracle-java8-installer

安装Elasticsearch

方法1 通过添加Elastic的软件包源列表利用软件包管理器安装Elasticsearch。

运行以下命令以将Elasticsearch公共GPG密钥导入apt：

代码语言：javascript复制
wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

接下来，创建Elasticsearch源列表：

代码语言：javascript复制
echo "deb http://packages.elastic.co/elasticsearch/${ELASTICSEARCH_VERSION}/debian stable main" | sudo tee -a /etc/apt/sources.list.d/elk.list

更新apt软件包数据库：

代码语言：javascript复制
sudo apt-get update

安装Elasticsearch

代码语言：javascript复制
sudo apt-get -y install elasticsearch

Elasticsearch已经安装完成。下面编辑其配置文件：

代码语言：javascript复制
sudo vi /etc/elasticsearch/elasticsearch.yml

限制来自外部的Elasticsearch实例访问活动（端口9200），找到指定network.host的一行，取消其注释并将其值替换为“localhost”：

代码语言：javascript复制
elasticsearch.yml excerpt (updated)network.host: localhost

启动elasticsearch

代码语言：javascript复制
sudo service elasticsearch restart

也可以使用 脚本 安装

代码语言：javascript复制
#!/bin/bash### USAGE
###
### ./ElasticSearch.sh 1.7 will install Elasticsearch 1.7
### ./ElasticSearch.sh will fail because no version was specified (exit code 1)
###
### CLI options Contributed by @janpieper
### Check http://www.elasticsearch.org/download/ for latest version of ElasticSearch### ElasticSearch version
if [ -z "$1" ]; then
 echo ""
 echo "  Please specify the Elasticsearch version you want to install!"
 echo ""
 echo "    $ $0 1.7"
 echo ""
 exit 1
fiELASTICSEARCH_VERSION=$1if [[ ! "${ELASTICSEARCH_VERSION}" =~ ^[0-9] .[0-9]  ]]; then
 echo ""
 echo "  The specified Elasticsearch version isn't valid!"
 echo ""
 echo "    $ $0 1.7"
 echo ""
 exit 2
fi### Install Java 8
cd ~
sudo apt-get install python-software-properties -y
sleep 1
sudo add-apt-repository ppa:webupd8team/java -y
sleep 1
sudo apt-get update
sleep 1
sudo apt-get install oracle-java8-installer -y### Download and install the Public Signing Key
wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -### Setup Repository
echo "deb http://packages.elastic.co/elasticsearch/${ELASTICSEARCH_VERSION}/debian stable main" | sudo tee -a /etc/apt/sources.list.d/elk.list### Install Elasticsearch
sudo apt-get update && sudo apt-get install elasticsearch -y### Start ElasticSearch
sudo service elasticsearch start### Lets wait a little while ElasticSearch starts
sleep 5### Make sure service is running
curl http://localhost:9200### Should return something like this:
# {
#  "status" : 200,
#  "name" : "Storm",
#  "version" : {
#    "number" : "1.3.1",
#    "build_hash" : "2de6dc5268c32fb49b205233c138d93aaf772015",
#    "build_timestamp" : "2014-07-28T14:45:15Z",
#    "build_snapshot" : false,
#    "lucene_version" : "4.9"
#  },
#  "tagline" : "You Know, for Search"
# }
安装到 Mac
  1. 到 https://www.elastic.co/downloads/elasticsearch 下载elasticsearch
  2. 解压 cd 到目录 执行
代码语言：javascript复制
sudo bin/elasticsearch

方法2 使用 docker

下载 elasticsearch 镜像

新建 docker-compose.yml 文件

代码语言：javascript复制
es:
  image: elasticsearch
  volumes:
    - /data:/usr/share/elasticsearch/data/
  ports:
    - "9200:9200"
  mem_limit: 2g
  environment:
   ES_JAVA_OPTS: "-Xmx1g -Xms1g"

运行命令

代码语言：javascript复制
docker-compose -f es-docker-compose.yml up -d

启动 elasticsearch

测试安装

浏览器中访问http://localhost:9200/，看到一个json结果集，表明安装成功：

代码语言：javascript复制
{
 "name" : "g1WVNJ8",
 "cluster_name" : "elasticsearch",
 "cluster_uuid" : "RjwyeM4kRRajDZzE3Tcq8g",
 "version" : {
   "number" : "5.4.0",
   "build_hash" : "780f8c4",
   "build_date" : "2017-04-28T17:43:27.229Z",
   "build_snapshot" : false,
   "lucene_version" : "6.5.0"
 },
 "tagline" : "You Know, for Search"
}
