手动安装部署Elasticsearch
开篇
开篇闲话，如果是新人在接触ELKstack什么都不懂的情况下，可以先看看各位前人写的关于ELKstack的博客，如何对ELKstack部署安装及使用，但是别人的东西只能作为借鉴，在自己搭建使用一定要以官方文档为准。
一定要注意软件版本，这里系统集合类软件，如果各软件版本不一致，会造成不可预估的后果！！！

部署
打开官网-->访问docs
我们以最新版本2.3来进行引导
下载方式安装
Installation
设置java环境
java -version
echo $JAVA_HOME
下载elasticsearch压缩包
curl -L -O https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.3/elasticsearch-2.3.3.tar.gz
解压压缩包，解压后可以直接使用
tar -xvf elasticsearch-2.3.3.tar.gz
cd elasticsearch-2.3.3/bin
启动elasticsearch
./elasticsearch
启动信息:
./elasticsearch

设置集群名和节点名
./elasticsearch --cluster.name my_cluster_name --node.name my_node_name
yum方式安装
安装GPG验证KEY
rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
把下面的源配置加入到 /etc/yum.repos.d/目录中的 a.repo文件里, 可以起名为：elasticsearch.repo
怎么配elasticsearch的repo源，我想中级以上的小伙伴都会
[elasticsearch-2.x]
name=Elasticsearch repository for 2.x packages
baseurl=https://packages.elastic.co/elasticsearch/2.x/centos
gpgcheck=1
gpgkey=https://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1
yum安装即可
yum install elasticsearch
基于salt自动化安装elasticsearch
此处只是分享下salt安装elasticsearch的模板，写的比较粗糙，也是刚开始写，很多自定义配置未加入到模板中，后面会逐步改进，内容里不会涉及新手的入门知识，此类入门知识会逐步在salt模块进行分享。
配置state目录
file_roots:
base_init:
- /etc/salt/states
配置top.sls
[root@sz-a-saltstack-xen states]# cat /etc/salt/states/top.sls
'*':
- init.yum_config
- init.selinux_shutdown
- init.limit
- init.sshd_config
- init.clock_config
- init.ntp_config
- init.user_config
- init.salt_minion_config
- init.tty_init
- init.zabbix_agent
'sz-a-qhfaxes0[1,3]-es-hw':
- jdk
- elkstack.es
配置elkstack 目录es.sls

上文sls模板存在问题：
1. 没有很好的使用到各类自定义和动态参数
2. 没有进行分层
我考虑应该使用一个应用的生命周期来进行分层，服务器始终保持无状态
