ELK概述部署和Filebeat 分布式日志管理平台部署

ELK是Elasticsearch、Logstash、Kibana的缩写，这三者是开源日志管理平台Elasticsearch的一部分。Filebeat是一个轻量级日志收集器，设计用于转发日志数据从你的主机到Logstash或Elasticsearch。

以下是部署ELK和Filebeat的基本步骤：

1. 部署Elasticsearch
2. 部署Kibana
3. 部署Logstash
4. 部署Filebeat

部署Elasticsearch

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install elasticsearch
sudo systemctl start elasticsearch
sudo systemctl enable elasticsearch

部署Kibana

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install kibana

在/etc/kibana/kibana.yml中配置Elasticsearch的URL。

sudo systemctl start kibana
sudo systemctl enable kibana

部署Logstash

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install logstash

创建Logstash配置文件，例如/etc/logstash/conf.d/myapp.conf，然后启动Logstash。

sudo systemctl start logstash
sudo systemctl enable logstash

部署Filebeat

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/7.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.x.list
sudo apt-get update && sudo apt-get install filebeat

在/etc/filebeat/filebeat.yml中配置输出到Logstash或Elasticsearch，并设置日志输入源。

sudo systemctl start filebeat
sudo systemctl enable filebeat

以上步骤是在基于Debian/Ubuntu的系统上的部署示例。对于Red Hat/CentOS等系统，需要使用yum替换apt-get。

注意：在生产环境中，你可能需要对Elasticsearch进行性能调优，配置集群，以及设置索引生命周期管理等。同时，确保Filebeat部署在所有需要监控的服务器上。
