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
