Elasticsearch6.0安裝

ELKStack簡介
        對於日志來說，最常見的需求就是收集、存儲、查詢、展示，開源社區正好有相對應的開源項目：logstash（收集）、elasticsearch（存儲+搜索）、kibana（展示），我們將這三個組合起來的技術稱之為ELKStack，所以說ELKStack指的是Elasticsearch、Logstash、Kibana技術棧的結合，一個通用的架構如下圖所示：

 

系統環境：Centos 7.4  JDK 1.8

Elasticsearch6.0安裝:

1、安裝JDK

[root@es-jypay-1 elasticsearch]# yum install -y java
[root@es-jypay-1 elasticsearch]# java -version
openjdk version "1.8.0_65"
OpenJDK Runtime Environment (build 1.8.0_65-b17)
OpenJDK 64-Bit Server VM (build 25.65-b01, mixed mode)

2、安裝Elasticsearch6.0

[root@es-jypay-1 elasticsearch]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.0.0.rpm

3、修改配置文件

[root@es-jypay-1 elasticsearch]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: jypay-es
node.name: es-jypay-1
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
bootstrap.memory_lock: true
network.host: 192.168.6.222
http.port: 9200

4、啟動並測試

啟動：
[root@es-jypay-1 elasticsearch]# systemctl start  elasticsearch.service

測試，看到如下打印信息表示服務正常啟動：
[root@es-jypay-1 elasticsearch]# curl http://192.168.6.222:9200
