编写logstash文件

[root@elk-node1 conf.d]# cat tcp.conf
input{
    tcp{
    host => "192.168.247.135"
    port => "8888"
    }    
}
output{
    stdout{
    codec => "rubydebug"
        }
}
#运行
[root@elk-node1 conf.d]# /opt/logstash/bin/logstash -f /etc/logstash/conf.d/tcp.conf
#另开一个窗口用nc的发请求
[root@elk-node1 ~]# yum install -y nc
[root@elk-node1 ~]# nc 192.168.247.135 8888 < /etc/passwd
[root@elk-node1 ~]# echo "hehehe" > /dev/tcp/192.168.247.135/8888
#在看第一个窗口就有数据了
[root@elk-node1 conf.d]# /opt/logstash/bin/logstash -f /etc/logstash/conf.d/tcp.conf
