centos7安装ELK6.5.3

简介

Elastic Stack也就是ELK,ELK是三款软件的检查，分别是Elasticsearch,logstas,Kibana组成，在发展过程中，有有了新的成员Beats加入,所以就形成了Elastic Starck.也是就是说ELK是旧的称呼，Elastic Stack是新的名字。

先通过Beats采集一切的数据如日志文件，网络流量，Win事件日志，服务指标，健康检查等，然后把数据发送elasticsearch保存起来，也可以发送给logstas处理然后再发送个elasticsearch,最后通过kibana的组件将数据可视化的展示出来

Elasticsearch

Elasticsearch基于java,是个开源分布式手术引擎，它的特点有：分布式，零配置，自动发现，索引自动分片，索引副本机制，restful风格接口，多数据源，自动搜索负载等。

Logstash

也是基于java,是一个开源的用于收集，分析和存储日志的工具。

Kibana

Kibana基于nodejs，也是开源和免费的工具，Kibana开源为logsash和Elasticsearch提供日志分析友好的web界面，可以汇总，分析和搜索重要的数据日志。

Beats

Bests是elastic公司开源的一款采集系统监控数据的代理agent，是在被监控服务器上以客户端形式运行的数据收集器的统称，可以直接把数据发送给Elasticsearch或者通过Logstash发送给Elasticsearch,然后进行后续的数据分析活动

创建elasticsearch用户，注意elasticsearch不能在root中启动。

[root@localhost ~]# useradd  elasticsearch
[root@localhost ~]# chown -R elasticsearch.elasticsearch  /usr/local/ELK/elasticsearch-6.5.3

#启动elasticsearch
[root@localhost ~]# su elasticsearch

配置和启动Logstash

在logstash目录创建文件default.conf，内容如下：

[elasticsearch@localhost ELK]$ exit
exit
#监听5044端口的数据打印至9200端口
[root@localhost ~]# vim /usr/local/ELK/logstash-6.5.3/default.conf# 监听5044端口作为输入
input {
    beats {
        port => "5044"
    }
}
# 数据过滤
filter {
    grok {
        match => { "message" => "%{COMBINEDAPACHELOG}" }
    }
    geoip {
        source => "clientip"
    }
}
# 输出配置为本机的9200端口，这是ElasticSerach服务的监听端口
output {
    elasticsearch {
        hosts => ["127.0.0.1:9200"]
    }
}

#后台启动logstash

配置和启动Kibana

#1.编辑Kibana的配置文件
[root@localhost logstash-6.5.3]# vim /usr/local/ELK/kibana-6.5.3-linux-x86_64/config/kibana.yml
......

server.host: "0.0.0.0"

pid.file: /var/run/kibana.pid
......

#2.启动服务
[root@localhost logstash-6.5.3]# nohup  /usr/local/ELK/kibana-6.5.3-linux-x86_64/bin/kibana &

#3.查看端口和日志确认是否正常启动
[root@localhost logstash-6.5.3]# netstat -tunlp|grep 5601

在浏览器访问http://ip:5601，看到如下页面：

ELK服务启动成功,在另一台上面收集nginx日志

配置kibana

安装supervisor

yum -y install epel-release
yum install -y supervisor

vim /etc/supervisord.conf
[inet_http_server]         ; inet (TCP) server disabled by default
port=192.168.248.135:9001        ; (ip_address:port specifier, *:port for all iface)
username=user              ; (default is no username (open server))
password=123               ; (default is no password (open server))

systemctl start supervisord

systemctl enable supervisord

使用网页的形式也能开启关闭服务

输入地址：http://ip:9001/ 输入账号密码

部署守护进程supervisor启动ELK
