把logstash输出内容到elasticsearch     参考:https://blog.csdn.net/napoay/article/details/53276758

建立配置文件：

vim logstash.conf
内容如下：

input{
    stdin{}
}
output{
    elasticsearch{
        hosts => "192.168.1.119"
     }
   stdout{codec => rubydebug}
}
然后执行：

[elk@linux-node1 elk]$ ./logstash-6.2.4/bin/logstash -f logstash-6.2.4/conf/logstash.conf

再打开http://192.168.1.119:9100进行查看

=======================================================================

收集系统日志:

[root@linux-node1 elk]# cat logstash-6.2.4/conf/file.conf
input {
file{
path => "/var/log/messages"
type => "system"
start_position => "beginning"
}

}
output {

elasticsearch {
hosts => ["192.168.1.119:9200"]
index => "system-%{type}-%{+YYYY.MM.dd}"

}

}

然后:    [elk@linux-node1 elk]$ ./logstash-6.2.4/bin/logstash -f logstash-6.2.4/conf/file.conf
