ElasticSearch 系列 (1) 单机安装部署

ElasticSearch 是分布式的全文检索系统，官方文档 地址： https://www.elastic.co/guide/index.html
笔者在centos 上部署ES 5.0 的集群，总结了一些经验教训。

1、部署单机的ES环境

详细的部署过程，在官方文档中已经很详细的说明。简要描述如下：

== 安装 GPG-KEY

sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

== 创建  /etc/yum.repos.d/elasticsearch.repo 文件，内容如下：

[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

== 安装 elasticsearch

sudo yum install elasticsearch

== 修改配置文件

vi /etc/elasticsearch/elasticsearch.yml

== 配置自启动

sudo systemctl daemon-reload
sudo systemctl enable elasticsearch

== 运行和停止

systemctl start elasticsearch
systemctl stop elasticsearch

== ES 安装完成后，默认的文件位置

type	description	location
home	Home of elasticsearch installation	/usr/share/elasticsearch
bin	Binary scripts including elasticsearch to start a node	/usr/share/elasticsearch/bin
conf	Configuration files elasticsearch.yml and logging.yml	/etc/elasticsearch
conf	Environment variables including heap size,file descriptors	/etc/sysconfig/elasticsearch
data	The location of the data files	/var/lib/elasticsearch/
logs	Log files location	/var/log/elasticsearch
plugins	Plugin files location	/usr/share/elasticsearch/plugins

2、安装kibana

== 创建 /etc/yum.repos.d/kibana.repo ，内容如下

[kibana-5.x]
name=Kibana repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

== 安装

sudo yum install kibana

== 配置自启动

sudo systemctl daemon-reload
sudo systemctl enable kibana

== 启动和停止

sudo systemctl start kibana
sudo systemctl stop kibana

kibana的文件位置：

配置文件 在 /etc/kibana/kibana.yml

安装目录  /usr/share/kibana

3、安装x-pack 

分别在elasticesearch的安装目录(/usr/share/elasticsearch）及kibana的安装目录（/usr/share/kibana）执行

bin/elasticsearch-plugininstall x-pack
bin/kibana-plugin install x-pack

4、检查是否工作正常

== 检查服务端口：elasticsearch 的9200，kibana的5601是否正常

sudo netstat -nltp

==使用浏览器访问：elasticsearch
http://192.168.0.21:9200
== 使用浏览器访问：kibana
http://192.168.0.21:5601
