下载logstash
目录如下，默认配置即可 [root@localhost logstash]# pwd /home/elk/logstash [root@localhost logstash]#
手动启动命令 ./logstash -f ../dev.conf nohup ./logstash -f ../dev.conf &
下载kibana
配置文件如下 [root@localhost config]# pwd /home/elk/kibana/config [root@localhost config]# grep -v "^#" kibana.yml server.host: "192.168.1.70" elasticsearch.hosts: ["http://192.168.1.70:9200"] kibana.index: ".kibana" i18n.locale: "zh-CN"

安装Elasticsearch -head yum install git npm git clone https://github.com/mobz/elasticsearch-head.git [root@localhost elasticsearch-head]# pwd /home/elk/elasticsearch-head [root@localhost elasticsearch-head]#
启动 npm install npm run start nohup npm run start &
curl -XPUT '192.168.2.67:9100/book'
访问192.168.2.67：9100 即可访问
下载kafka
修改配置文件如下 [root@localhost config]# pwd /home/elk/kafka/config [root@localhost config]# grep -v "^#" server.properties broker.id=0 listeners=PLAINTEXT://192.168.1.70:9092 num.network.threads=3 num.io.threads=8 socket.send.buffer.bytes=102400 socket.receive.buffer.bytes=102400 socket.request.max.bytes=104857600 log.dirs=/var/log/kafka-logs 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 delete.topic.enable=true [root@localhost config]#

测试kafka
新建一个名字为test的topic /kafka-topics.sh --create --zookeeper 192.168.1.70:2181 --replication-factor 1 --partitions 1 --topic test
查看kafka中的topic ./kafka-topics.sh --list --zookeeper 192.168.1.70:2181
往kafka topic为test中 生产消息 ./kafka-console-producer.sh --broker-list 192.168.1.70:9092 --topic test
在kafka topic为test中 消费消息 bin/kafka-console-consumer.sh --bootstrap-server 192.168.1.70:9092 --topic test --from-beginning
生产的消息，消费那边接受到即是ok的
目标机器安装filebeat
安装6.5版本的 [root@localhost filebeat]# pwd /usr/local/filebeat [root@localhost filebeat]# cat filebeat.yml filebeat.prospectors: - type: log paths: - /opt/logs/workphone-tcp/catalina.out fields: tag: 54_tcp_catalina_out - type: log paths: - /opt/logs/workphone-webservice/catalina.out fields: tag: 54_web_catalina_out name: 192.168.1.54 filebeat.config.modules: path: ${path.config}/modules.d/*.yml reload.enabled: false setup.template.settings: index.number_of_shards: 3 output.kafka: hosts: ["192.168.1.70:9092"] topic: "filebeat-log" partition.hash: reachable_only: true compression: gzip max_message_bytes: 1000000 required_acks: 1
