ELK日志环境入门-02之Logstash官方源码部署

一、ELK 简介

ELK 是一个开源的实时日志分析平台,它主要由 Elasticsearch、Logstash 和 Kiabana 三部分组成。

二、Logstash概述

Logstash 主要用于收集服务器日志,它是一个开源数据收集引擎,具有实时管道功能。Logstash 可以动态地将来自不同数据源的数据统一起来,并将数据标准化到您所选择的目的地。

Logstash 收集数据的过程主要分为以下三个部分:

  • 输入:数据(包含但不限于日志)往往都是以不同的形式、格式存储在不同的系统中,而 Logstash 支持从多种数据源中收集数据(File、Syslog、MySQL、消息中间件等等)。
  • 过滤器:实时解析和转换数据,识别已命名的字段以构建结构,并将它们转换成通用格式。
  • 输出:Elasticsearch 并非存储的唯一选择,Logstash 提供很多输出选择。

三、ELK 平台搭建基于Logstash官方源码部署

本节主要介绍搭建 ELK 日志平台,包括安装 Indexer 角色的 Logstash,Elasticsearch 以及 Kibana 三个组件。完成本小节,您需要做如下准备:

  1. 一台 Linux/CentOS 机器或虚拟机,作为入门教程,此处省略了 Elasticsearch 集群的搭建,将 Logstash(Indexer)、Elasticsearch 以及 Kibana 安装在不同机器上,即ELK分布式部署。
  2. 在 Linux/CentOS 上安装 JDK,注意 Logstash 要求 JDK 在 1.8 版本或以上。
  3. ELK官方组件下载,您可以在 ELK源码下载
  4. 本文详细演示Logstash官方源码部署

四、Logstash官方源码部署

1、安装依赖环境

[root@node opt]# wget https://download.oracle.com/otn/java/jdk/8u301-b09/d3c52aa6bfa54d3ca74e617f18309292/jdk-8u301-linux-x64.rpm?AuthParam=1630374823_29c8a62eebc8754fe26188019ff8acfc

[root@node opt]# rpm -ivh jdk-8u301-linux-x64.rpm

正在升级/安装...
   1:jdk1.8-2000:1.8.0_301-fcs        ################################# [100%]

2、下载elastic官网最新版本Logstash-7.14.0

[root@node ~]# ll /opt/
总用量 426068
-rw-r--r--  1 root root 321737210 8月  31 09:49 kibana-7.14.0-linux-x86_64.tar.gz

3、创建并解压至自定义目录

[root@node ~]# tar xf /opt/logstash-7.14.0-linux-x86_64.tar.gz -C /usr/local/elk/

4、 修改 logstash .yml 文件配置

http.host: 10.100.202.102     //局域网ip或者公网ip

5、举例创建常见TCP日志收集管道

[root@node ~]# vim /usr/local/elk/logstash-7.14.0/config/tcp.conf
## 添加如下内容
input{
  tcp{
   type => "tcp"
   mode => "server"
   port => "9601"
   host => "10.100.202.102"     //logstash主机IP
   codec => json_lines
  }
}

output{
     elasticsearch{
     hosts =>["10.100.202.100:9200"]     //elasticserach主机IP
     index=>"tcp_log-%{+YYYY.MM.dd}.log"
     #user => "elastic"
     #password => "BH@yihubai!"
    }
}

6、启动验证服务是否正常

[root@node ~]# /usr/local/elk/logstash-7.14.0/bin/logstash -f /usr/local/elk/logstash-7.14.0/config/tcp.conf &
[root@node ~]# ss -lnt

7、创建Logstash开机自启动脚本

[root@node ~]# vim /etc/systemd/system/logstash.service
## 粘贴如下内容

[Unit]
Description=logstash

[Service]
Type=simple
User=root
Group=root
ExecStart=/usr/local/elk/logstash-7.14.0/bin/logstash -f /usr/local/elk/logstash-7.14.0/config/tcp.conf
Restart=always
LimitNOFILE=16384

[Install]
WantedBy=multi-user.target

授权脚本777权限

[root@node ~]# chmod 777 /etc/systemd/system/logstash.service

常用命令

systemctl enable logstash
systemctl start logstash
systemctl status logstash # 查看状态
