Logstash学习之路(一)Logstash的安装
一、Logstash简介
Logstash 是一个实时数据收集引擎,可收集各类型数据并对其进行分析,过滤和归纳。按照自己条件分析过滤出符合数据导入到可视化界面。它可以实现多样化的数据源数据全量或增量传输,数据标准格式处理,数据格式化输出等的功能,常用于日志处理。工作流程分为三个阶段:
(1)input数据输入阶段,可接收oracle、mysql、postgresql、file等多种数据源;
(2)filter数据标准格式化阶段,可过滤、格式化数据,如格式化时间、字符串等;
(3)output数据输出阶段,可输出到elasticsearch、mongodb、kfka等接收终端。
二、下载
说明:由于我安装的Elasticsearch版本为6.3.1,因此我下载logstash版本为6.31
https://artifacts.elastic.co/downloads/logstash/logstash-6.3.1.tar.gz
解压:
[root@master mnt]# tar -zxvf logstash-6.3.1.tar.gz
[root@master mnt]# mv logstash-6.3.1 logstash
简单输出到控制台,观察是否安装成功:
[root@master bin]# ./logstash -e 'input { stdin { } } output { stdout {} }'
日志:

输入:aaaaaaaa,发现安装成功
aaaaaaaaaa { "message" => "aaaaaaaaaa", "host" => "master", "@timestamp" => 2019-04-24T08:21:07.403Z, "@version" => "1" }

参数: 执行 -e bin /logstash -e '' 文件 --config 或 -f bin /logstash -f agent.conf 测试 --configtest 或 -t 用来测试 Logstash 读取到的配置文件语法是否能正常解析。 日志 --log 或 -l Logstash 默认输出日志到标准错误。生产环境下你可以通过 bin /logstash -l logs /logstash .log 命令来统一存储日志。 |
实例操作:
以输出到Elasticsearch为例:接收控制台输入,Logstash解析输出到ElasticSearch集群
[root@master bin]# cat test_es.conf input{ stdin{} } output{ elasticsearch{ hosts=>["192.168.200.100:9200"] index=>"testeslogstash" } stdout{codec=>rubydebug} }
运行:
[root@master bin]# ./logstash -f /mnt/logstash/bin/test_es.conf
结果:
所以搭建成功。
