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：
1
|
sudo add-apt-repository -y ppa:webupd8team/java
|
更新apt软件包数据库：
HUGOMORE42
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）：
1
|
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：
1
|
wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
|
接下来，创建Elasticsearch源列表：
1
|
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：
安装Elasticsearch
1
|
sudo apt-get -y install elasticsearch
|
Elasticsearch已经安装完成。下面编辑其配置文件：
1
|
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”：
1

3
|
elasticsearch.yml excerpt (updated)
network.host: localhost
|
启动elasticsearch
1
|
sudo service elasticsearch restart
|
也可以使用 脚本 安装
