Logstash接收Kafka数据写入至ES_logstash kafka es

1 Kafka数据写入至ES方式

• Kafka->logstash->elasticsearch->kibana(简单，只需启动一个代理程序)
  根据以上情况，项目决定采用方案一将Kafka中的数据存入到elasticsearch中去。
  项目拓扑图如下所示：

此时消息的整体流向为：日志/消息整体流向Flume => kafka => logstash => elasticsearch => kibana

2 环境搭建

Logstash同步MySql数据到Elasticsearch

input {
kafka {
bootstrap_servers => "192.168.1.252:9092" #kafka服务器地址
topics => "252nginx-accesslog"
batch_size => 5
codec => "json" #写入的时候使用json编码，因为logstash收集后会转换成json格式
group_id => "252nginx-access-log"
consumer_threads => 1
decorate_events => true
}
kafka {
bootstrap_servers => "192.168.1.252:9092"
topics => "system-log-252"
consumer_threads => 1
decorate_events => true
codec => "json"
}
}
output {
if [type] == "252nginx-accesslo" {
elasticsearch {
hosts => ["192.168.1.252:9200"]
index => "252nginx-accesslog-%{+YYYY.MM.dd}"}}
if [type] == "system-log-252" {
elasticsearch {
hosts => ["192.168.1.252:9200"]
index => "system-log-1512-%{+YYYY.MM.dd}"
}
}
