1.0.0
- Released November 1, 2017
- Source download: kafka-1.0.0-src.tgz (asc, sha512)

- Scala 2.12 - kafka_2.12-1.0.0.tgz (asc, sha512)
We build for multiple versions of Scala. This only matters if you are using Scala and you want a version built for the same Scala version you use. Otherwise any version should work (2.11 is recommended).
1.解压：tar zxvf kafka_2.11-1.0.0.tgz
2.部署目录：mv kafka_2.12-1.0.0 /usr/local/kafka2.12
3.启动zookeeper ....
4.启动kafka：
#nohup bin/kafka-server-start.sh config/server.properties &
5.创建topic：
#bin/kafka-topics.sh --create --zookeeper localhost:2181 --partitions 1 --replication-factor 1 --topic test
Created topic "test".
6.查看topic：
# bin/kafka-topics.sh --list --zookeeper localhost:2181
__consumer_offsets
test
7.测试发送数据
#bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
输入：my test
8.测试消费消息：
#bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning

1.下载：wget apache-flume-1.8.0-bin.tar.gz
2.解压：tar zxvf apache-flume-1.8.0-bin.tar.gz
3.设置目录：mv apache-flume-1.8.0-bin /usr/local/flume1.8
4.准备工作：
安装java并设置java环境变量,flume环境变量，在`/etc/profile`中加入
export JAVA_HOME=/usr/java/jdk1.8.0_65
export FLUME_HOME=/usr/local/flume1.8
export PATH=$PATH:$JAVA_HOME/bin:$FLUME_HOME
执行：source /etc/profile 生效变量
5.建立log采集目录：
/tmp/logs/kafka.log
6.配置
拷贝配置模板：
# cp conf/flume-conf.properties.template conf/flume-conf.properties
# cp conf/flume-env.properties.template conf/flume-env.properties
编辑配置如下：
agent.sources = s1
agent.channels = c1
agent.sinks = k1
agent.sources.s1.type=exec
#日志采集位置
agent.sources.s1.command=tail -F /tmp/logs/kafka.log
agent.sources.s1.channels=c1
agent.channels.c1.type=memory
agent.channels.c1.capacity=10000
agent.channels.c1.transactionCapacity=100
agent.sinks.k1.type= org.apache.flume.sink.kafka.KafkaSink
#kafka 地址
agent.sinks.k1.brokerList=localhost:9092
#kafka topic
agent.sinks.k1.topic=test
agent.sinks.k1.serializer.class=kafka.serializer.StringEncoder
agent.sinks.k1.channel=c1
功能验证
7.启动服务
# bin/flume-ng agent --conf ./conf/ -f conf/kafka.properties -Dflume.root.logger=DEBUG,console -n agent
运行日志位于logs目录，或者启动时添加-Dflume.root.logger=INFO,console 选项前台启动，输出打印日志，查看具体运行日志，服务异常时查原因。
8.创建测试日志生成：log_producer_test.sh
for((i=0;i<=1000;i++));
do echo "kafka_flume_test-"+$i>>/tmp/logs/kafka.log;
do
9.生成日志：
./log_producer_test.sh
观察kafka日志消费情况。。。
