1.logstash的配置

[root@VM_0_4_centos config]# cat wxqyh.yml|egrep -v '^$|^#'
input {
     file {
          type => "4personal20001"
          path => "/mnt/data/logs/personal_20001/log4j.log"
          start_position => "beginning"
          sincedb_path => "/dev/null"
          codec => multiline {
          pattern => "^%{TIMESTAMP_ISO8601}"
          negate => true
          what => "previous"
    }
}
     file {
          type => "4personal20002"
          path => "/mnt/data/logs/personal_20002/log4j.log"
          start_position => "beginning"
          sincedb_path => "/dev/null"
          codec => multiline {
          pattern => "^%{TIMESTAMP_ISO8601}"
          negate => true
          what => "previous"
    }
}
}
filter { 
 
grok   { 
     match => { 
               "message" => "^%{TIMESTAMP_ISO8601}\[%{WORD:level} %{GREEDYDATA:ajpcon}\| %{GREEDYDATA:data}" 
              } 
              match => { 
               "message" => "^%{TIMESTAMP_ISO8601}\[ %{WORD:level} %{GREEDYDATA:ajpcon}\| %{GREEDYDATA:data}" 
              } 
              remove_field  => "message" 
       } 
       }
output {    
    if [type] == "4personal20001" {
    kafka {
           max_request_size => 10485761
           bootstrap_servers => "10.0.0.134:9092"
           topic_id => "topic4personal1"
           compression_type => "snappy"
          }   
}
    if [type] == "4personal20002" {
    kafka {
           max_request_size => 10485761
           bootstrap_servers => "10.0.0.134:9092"
           topic_id => "topic4personal2"
           compression_type => "snappy"
          }   
}
}

2.kafka的配置

[root@VM_0_134_centos config]# cat server.properties|egrep -v '^$|^#'
broker.id=0
listeners=PLAINTEXT://10.0.0.134:9092
advertised.listeners=PLAINTEXT://10.0.0.134:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
message.max.bytes=20000000
replica.fetch.max.bytes=20485760
log.dirs=/mnt/data/monitor01/kafka_2.11-1.1.0/data
num.partitions=1
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0

3.logstash2的配置

[root@VM_0_134_centos config]# cat haode.yml|egrep -v '^$|^#'
input {
  kafka {
     type => "topic12wxqyh8"
     codec => "plain"
     topics => ["topic12wxqyh8"]
     client_id => "es1"
     group_id => "es1"
     bootstrap_servers => "10.0.0.134:9092"
  }
 
  kafka {
     type => "topic12wxqyh9"
     codec => "plain"
     topics => ["topic12wxqyh9"]
     client_id => "es2"
     group_id => "es2"
     bootstrap_servers => "10.0.0.134:9092"
  }
  kafka {
     type => "topic24wxqyh6"
     codec => "plain"
     topics => ["topic24wxqyh6"]
     client_id => "es3"
     group_id => "es3"
     bootstrap_servers => "10.0.0.134:9092"
  }
 
  kafka {
     type => "topic24wxqyh7"
     codec => "plain"
     topics => ["topic24wxqyh7"]
     client_id => "es4"
     group_id => "es4"
     bootstrap_servers => "10.0.0.134:9092"
  }
 
  kafka {
     type => "topic4personal1"
     codec => "plain"
     topics => ["topic4personal1"]
     client_id => "es5"
     group_id => "es5"
     bootstrap_servers => "10.0.0.134:9092"
  }
  kafka {
     type => "topic4personal2"
     codec => "plain"
     topics => ["topic4personal2"]
     client_id => "es6"
     group_id => "es6"
     bootstrap_servers => "10.0.0.134:9092"
  }
 
}
 
output {
  if [type] == "topic12wxqyh8" {
     elasticsearch {
       index => "topic12wxqyh8"
       hosts => ["10.0.0.7:9200"]
     }
  }
   
  if [type] == "topic12wxqyh9" {
     elasticsearch {
        index => "topic12wxqyh9"
        hosts => ["10.0.0.7:9200"]
     }
  }
  if [type] == "topic24wxqyh6" {
     elasticsearch {
       index => "topic24wxqyh6"
       hosts => ["10.0.0.7:9200"]
     }
  }
  if [type] == "topic24wxqyh7" {
     elasticsearch {
       index => "topic24wxqyh7"
       hosts => ["10.0.0.7:9200"]
     }
  }
  if [type] == "topic4personal1" {
     elasticsearch {
       index => "topic4personal1"
       hosts => ["10.0.0.7:9200"]
     }
  }

     }
  }
}

4.kafka的问题：

4.1zookeeper--选主，提供访问入口

4.2 Kafka的原理

生产者将数据发送到Broker代理，Broker代理有多个话题topic，消费者从Broker获取数据。
