Centos7下使用ELK（Elasticsearch + Logstash + Kibana）搭建日志集中分析平台

　　日志监控和分析在保障业务稳定运行时，起到了很重要的作用，不过一般情况下日志都分散在各个生产服务器，且开发人员无法登陆生产服务器，这时候就需要一个集中式的日志收集装置，对日志中的关键字进行监控，触发异常时进行报警，并且开发人员能够查看相关日志。logstash+elasticsearch+kibana3就是实现这样功能的一套系统，并且功能更强大。

　　Logstash：负责日志的收集，处理和储存
　　Elasticsearch：负责日志检索和分析
　　Kibana：负责日志的可视化

The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
) A unit may be started when needed via activation (socket, path, timer,

logstash-forwarder.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig logstash-forwarder on
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).

5、界面验证

　　首先在client中手动增加一条日志：

[root@localhost elk]# logger zhenyuLogtest

　　界面登录 http://192.168.7.27/ ，做如下操作

从图中可以看到，手动添加的日志已经在界面中被搜索到了。

本文主要参考了国外一个搭建ELK的视频，操作的很详细，附上视频的下载链接，仅供参考。
