一、flume配置

flume要求1.6以上版本

flume-conf.properties文件配置内容，sinks的输出作为kafka的product

flume启动

bin/flume-ng agent --conf conf --conf-file conf/flume-conf.properties --name a1 -Dflume.root.logger=INFO,console

二 kafka的消费者java源代码

kafka启动命令

启动Zookeeper server：

bin/zookeeper-server-start.shconfig/zookeeper.properties&

启动Kafka server:

bin/kafka-server-start.shconfig/server.properties&

运行producer：

bin/kafka-console-producer.sh--broker-listlocalhost:9092--topictest

运行consumer：

bin/kafka-console-consumer.sh--zookeeperlocalhost:2181--topictest--from-beginning

二、示例

pom.xml代码

1. ZooKeeper

安装参考

2. Kafka

2.1 解压安装

# 确保scala已经安装好，本文安装的是2.11.7
tar -xf kafka_2.11-0.9.0.1.tgz
cd kafka_2.11-0.9.0.1
mkdir logs

vim ~/.bash_profile

export KAFKA_HOME=/home/zkpk/kafka_2.11-0.9.0.1
export PATH=$PATH:$KAFKA_HOME/bin

2.2 配置

2.2.1 server.properties

只设置了以下4项，其他使用默认值

# 当前机器在集群中的唯一标识，和zookeeper的myid性质一样
broker.id=0

host.name=hsm01

# 消息存放的目录，这个目录可以配置为“，”逗号分割的表达式，
# 上面的num.io.threads要大于这个目录的个数这个目录，如果配置多个目录，
# 新创建的topic他把消息持久化的地方是，当前以逗号分割的目录中，
# 那个分区数最少就放那一个
log.dirs=/home/zkpk/kafka_2.11-0.9.0.1/logs

# 配置自定义的ZooKeeper
zookeeper.connect=hsm01:2181,hss01:2181,hss02:2181/kafka
