logstash 配置

下载 logstash
https://www.elastic.co/downloads/past-releases/logstash-6-3-2

需要配置好 java 的环境变量
验证 Logstash

[river@localhost bin]$ pwd
/soft/logstash-6.3.2/bin
[river@localhost bin]$ ./logstash -e 'input { stdin { } } output { stdout {} }'
Sending Logstash's logs to /soft/logstash-6.3.2/logs which is now configured via log4j2.properties

The stdin plugin is now waiting for input:
[2019-03-22T01:00:10,360][INFO ][logstash.pipeline        ] Pipeline started successfully {:pipeline_id=>"main", :thread=>"#<Thread:0x45e95705 sleep>"}

[2019-03-22T01:00:10,534][INFO ][logstash.agent           ] Successfully started Logstash API endpoint {:port=>9600}

看到已经成功start 了。
输入字符测试下

hello world
{
      "@version" => "1",
          "host" => "localhost.localdomain",
       "message" => "hello world",
    "@timestamp" => 2019-03-21T17:01:59.662Z
}

读取文件 并输出的文件
配置文件 simple.conf 如下

input {
  file {
    type => "messagelog"  
    path => "/home/river/Documents/messages"
    start_position => "beginning"       
    }
}

output {
  file {
    path => "/home/river/Documents/%{type}.%{+YYYY.MM.dd}"  
  }
}

执行命令
./bin/logstash -f config/simple.conf
结果

[river@localhost Documents]$ echo "hello world" >> /home/river/Documents/messages
[river@localhost Documents]$ cat /home/river/Documents/messagelog.2019.03.21 
{"type":"messagelog","@timestamp":"2019-03-21T18:56:11.725Z","host":"localhost.localdomain","message":"hello world","@version":"1","path":"/home/river/Documents/messages"}

保存到 elasticsearch 里面

output {
   elasticsearch { hosts => ["192.168.130.105:9200"] }
}

如果想同时输出到控制台 out put 里添加： stdout { codec => rubydebug }
即

output {
  elasticsearch { hosts => ["192.168.130.105:9200"] } 
  stdout { codec => rubydebug } 
}

启动并向文件里写入数据
