丝路通:Kafka数据缓存

步骤

1.创建Kafka主题

2.创建Kafka消费者

3.创建定时任务

4.通过Flume数据采集到Kafka

操作步骤

启动zookeeper和kafka

参考：丝路通:Kafka单机版安装

创建Kafka主题

[root@master kafka_2.11-2.3.1]cd kafka_2.11-2.3.1/

[root@master kafka_2.11-2.3.1]# bin/kafka-topics.sh -create --zookeeper 10.0.0.30:2181 -replication-factor 1 --partitions 1 --topic goods

Created topic goods.

[root@master kafka_2.11-2.3.1]# bin/kafka-topics.sh --list --zookeeper 10.0.0.30:2181

__consumer_offsets
goods

创建消费者

[root@slave1 kafka_2.11-2.3.1]# bin/kafka-console-consumer.sh --bootstrap-server 10.0.0.30:9092 --topic goods --from-beginning

复制文件到采集区

将清洗后的数据文件 0820_ali_xiaolong.csv 复制到采集区 /opt/flinkproject

开启Flume数据采集到Kafka

/usr/local/flume/bin/flume-ng agent -c /usr/local/flume/conf/ -f /usr/local/flume/conf/spool-memory-kafka.conf -n client -Dflume.root.logger=INFO,console

Info: Including HBASE libraries found via (/usr/local/hbase-1.3.6/bin/hbase) for HBASE access
Info: Including Hive libraries found via (/usr/local/apache-hive-1.2.1-bin) for Hive access
...

在Kafka消费者端查看

[root@slave1 kafka_2.11-2.3.1]# bin/kafka-console-consumer.sh --bootstrap-server 10.0.0.30:9092 --topic goods --from-beginning
