使用 Elastic Stack 构建日志分析系统

wget https://artifacts.elastic.co/downloads/logstash/logstash-6.4.3.tar.gz
tar xvf logstash-6.4.3.tar.gz

input {
 file {
     path => "/var/log/nginx/access.log" # nginx 访问日志的路径
     start_position => "beginning" # 从文件起始位置读取日志，如果不设置则在文件有写入时才读取，类似于 tail -f
 }
}
filter {
}
output {
 elasticsearch {
     hosts => ["http://172.16.0.145:9200"] # ES 集群的内网 VIP 地址和端口
     index => "nginx_access-%{+YYYY.MM.dd}" # 索引名称, 按天自动创建索引
     user => "elastic" # 用户名
     password => "yinan_test" # 密码
  }
}
