前期博客
Filebeat的下载（图文讲解）
前提
Elasticsearch-2.4.3的下载（图文详解）
Elasticsearch-2.4.3的单节点安装（多种方式图文详解）
Elasticsearch-2.4.3的3节点安装（多种方式图文详解）
Logstash安装（图文详解）（多节点的ELK集群安装在一个节点就好）
Kibana安装（图文详解）（多节点的ELK集群安装在一个节点就好）
在此基础上，我们安装好ELK（Elasticsearch、Logstasg和kibana）之后，我们继续来安装，Filebeat。
Filebeat是轻量级的日志收集工具，使用go语言开发。
我这里的机器集群情况分别是：
HadoopMaster（192.168.80.10）、HadoopSlave1（192.168.80.11）和HadoopSlave2（192.168.80.12）。

[hadoop@HadoopMaster app]$
4、解读认识Filebeat的目录结构
这里，仅仅是在HadoopMaster安装，为例。
[hadoop@HadoopMaster app]$ cd filebeat-1.3.1-x86_64/
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ pwd
/home/hadoop/app/filebeat-1.3.1-x86_64
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ ll
total 11116
-rwxr-xr-x. 1 hadoop hadoop 11354200 Sep 15 2016 filebeat
-rw-r--r--. 1 hadoop hadoop 814 Sep 15 2016 filebeat.template.json
-rw-r--r--. 1 hadoop hadoop 17212 Sep 15 2016 filebeat.yml
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$
5、修改filebeat.yml文件配置文件
filebeat.yml（中文配置详解）
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ pwd
/home/hadoop/app/filebeat-1.3.1-x86_64
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ vim filebeat.yml
默认，/var/log/*.log。即监控/var/log下这个目录里所有以.log结尾的文件。
同时，比如配置的如果是：
则只会去/var/log目录的所有子目录中寻找以”.log”结尾的文件，而不会寻找/var/log目录下以”.log”结尾的文件。
注意：
如果说，你收集的日志，不需做任何解析，则可以用Filebeat收集到es里。
因为，我这里是，请移步,
ELK之日志查询、收集与分析系统
采用的是，如下这么一个架构。
架构设计3：filebeat(1.3)（3台）-->redis-->logstash(parse)-->es集群-->kibana--ngix（可选） （我这里，目前为了学习，走这条线路）
所以，我这里就把默认的（filebeat收集后放到es里)，给注销掉。以后自己可以改回来。
启动 filebeat
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ pwd
/home/hadoop/app/filebeat-1.3.1-x86_64
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ ll
total 11116
-rwxr-xr-x. 1 hadoop hadoop 11354200 Sep 15 2016 filebeat
-rw-r--r--. 1 hadoop hadoop 814 Sep 15 2016 filebeat.template.json
-rw-r--r--. 1 hadoop hadoop 17212 Sep 15 2016 filebeat.yml
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ ./filebeat -c filebeat.yml
初步修改好配置文件之后，我这里打开HadoopMaster（因为Filebeat安装在这台）的另一个窗口。
[hadoop@HadoopMaster ~]$ pwd
/home/hadoop
[hadoop@HadoopMaster ~]$ ll

drwxrwxr-x. 11 hadoop hadoop 4096 Mar 26 18:49 app

[hadoop@HadoopMaster ~]$ echo My name is zhouls >> app.log
[hadoop@HadoopMaster ~]$ more app.log
My name is zhouls

立马，对应这边，是
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ ll

-rwxr-xr-x. 1 hadoop hadoop 11354200 Sep 15 2016 filebeat

-rw-r--r--. 1 hadoop hadoop 17218 Mar 26 19:58 filebeat.yml
[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ ./filebeat -c filebeat.yml

同时，继续等待下一个的数据收集，其实啊，功能类似与hadoop里的flume。这个很简单

为了后期调试和排除问题方便。建议开启日志(可选)

[hadoop@HadoopMaster filebeat-1.3.1-x86_64]$ vim filebeat.yml

然后，我们再次启动filebeat，来查看它的日志
