上面两个中文链接是Kafka的产生的背景和中文教程，后面两个英文连接对应的是官方kafka的框架介绍和入门教程，这些我们不再说，直接下载kafka，我们以最新版本0.11.0.1为准，来看认识一下kafka的目录结构：
下载kafka：
[donald@Donald_Draper ~]$ ls Desktop Documents Downloads kafka_2.11-0.11.0.1.tgz Music Pictures Public Templates Videos [donald@Donald_Draper ~]$
解压：
[donald@Donald_Draper ~]$ tar -zxvf kafka_2.11-0.11.0.1.tgz kafka_2.11-0.11.0.1/ kafka_2.11-0.11.0.1/LICENSE kafka_2.11-0.11.0.1/NOTICE kafka_2.11-0.11.0.1/bin/ ... kafka_2.11-0.11.0.1/libs/connect-json-0.11.0.1.jar kafka_2.11-0.11.0.1/libs/connect-file-0.11.0.1.jar kafka_2.11-0.11.0.1/libs/kafka-streams-0.11.0.1.jar kafka_2.11-0.11.0.1/libs/rocksdbjni-5.0.1.jar kafka_2.11-0.11.0.1/libs/kafka-streams-examples-0.11.0.1.jar [donald@Donald_Draper ~]$ ls Desktop Documents Downloads kafka_2.11-0.11.0.1 kafka_2.11-0.11.0.1.tgz Music Pictures Public Templates Videos [donald@Donald_Draper ~]$ [donald@Donald_Draper ~]$ cd kafka_2.11-0.11.0.1/ [donald@Donald_Draper kafka_2.11-0.11.0.1]$ ls bin config libs LICENSE NOTICE site-docs
从上面来看解压后的文件夹 kafka_2.11-0.11.0.1内有bin，config，libs主要文件夹，
下面分别来看这几个文件夹下的文件：
先来看bin目录下：
[donald@Donald_Draper kafka_2.11-0.11.0.1]$ cd bin/ [donald@Donald_Draper bin]$ ls connect-distributed.sh kafka-delete-records.sh kafka-simple-consumer-shell.sh connect-standalone.sh kafka-mirror-maker.sh kafka-streams-application-reset.sh kafka-acls.sh kafka-preferred-replica-election.sh kafka-topics.sh kafka-broker-api-versions.sh kafka-producer-perf-test.sh kafka-verifiable-consumer.sh kafka-configs.sh kafka-reassign-partitions.sh kafka-verifiable-producer.sh kafka-console-consumer.sh kafka-replay-log-producer.sh windows kafka-console-producer.sh kafka-replica-verification.sh zookeeper-security-migration.sh kafka-consumer-groups.sh kafka-run-class.sh zookeeper-server-start.sh kafka-consumer-offset-checker.sh kafka-server-start.sh zookeeper-server-stop.sh kafka-consumer-perf-test.sh kafka-server-stop.sh zookeeper-shell.sh
从上面来看bin主要是sh脚本，
再来看config文件夹：
[donald@Donald_Draper bin]$ cd .. [donald@Donald_Draper kafka_2.11-0.11.0.1]$ ls bin config libs LICENSE NOTICE site-docs [donald@Donald_Draper kafka_2.11-0.11.0.1]$ cd config/ [donald@Donald_Draper config]$ ls connect-console-sink.properties connect-file-source.properties log4j.properties zookeeper.properties connect-console-source.properties connect-log4j.properties producer.properties connect-distributed.properties connect-standalone.properties server.properties connect-file-sink.properties consumer.properties tools-log4j.properties
主要生产者消息者配置文件，日志配置文件，broker配置文件，connect和内置zookeeper配置文件；
再来看site-docs文件夹：
[donald@Donald_Draper config]$ cd .. [donald@Donald_Draper kafka_2.11-0.11.0.1]$ ls bin config libs LICENSE NOTICE site-docs [donald@Donald_Draper kafka_2.11-0.11.0.1]$ cd site-docs/ [donald@Donald_Draper site-docs]$ ls kafka_2.11-0.11.0.1-site-docs.tgz
这个应该是帮助文档；再来看lib文件夹
[donald@Donald_Draper site-docs]$ [donald@Donald_Draper kafka_2.11-0.11.0.1]$ ls bin config libs LICENSE NOTICE site-docs [donald@Donald_Draper kafka_2.11-0.11.0.1]$ cd libs/ [donald@Donald_Draper libs]$ ls aopalliance-repackaged-2.5.0-b05.jar jersey-common-2.24.jar kafka_2.11-0.11.0.1-test-sources.jar argparse4j-0.7.0.jar jersey-container-servlet-2.24.jar kafka_2.11-0.11.0.1-test-sources.jar.asc commons-lang3-3.5.jar jersey-container-servlet-core-2.24.jar kafka-clients-0.11.0.1.jar connect-api-0.11.0.1.jar jersey-guava-2.24.jar kafka-log4j-appender-0.11.0.1.jar connect-file-0.11.0.1.jar jersey-media-jaxb-2.24.jar kafka-streams-0.11.0.1.jar connect-json-0.11.0.1.jar jersey-server-2.24.jar kafka-streams-examples-0.11.0.1.jar connect-runtime-0.11.0.1.jar jetty-continuation-9.2.15.v20160210.jar kafka-tools-0.11.0.1.jar connect-transforms-0.11.0.1.jar jetty-http-9.2.15.v20160210.jar log4j-1.2.17.jar guava-20.0.jar jetty-io-9.2.15.v20160210.jar lz4-1.3.0.jar hk2-api-2.5.0-b05.jar jetty-security-9.2.15.v20160210.jar maven-artifact-3.5.0.jar hk2-locator-2.5.0-b05.jar jetty-server-9.2.15.v20160210.jar metrics-core-2.2.0.jar hk2-utils-2.5.0-b05.jar jetty-servlet-9.2.15.v20160210.jar osgi-resource-locator-1.0.1.jar jackson-annotations-2.8.5.jar jetty-servlets-9.2.15.v20160210.jar plexus-utils-3.0.24.jar jackson-core-2.8.5.jar jetty-util-9.2.15.v20160210.jar reflections-0.9.11.jar jackson-databind-2.8.5.jar jopt-simple-5.0.3.jar rocksdbjni-5.0.1.jar jackson-jaxrs-base-2.8.5.jar kafka_2.11-0.11.0.1.jar scala-library-2.11.11.jar jackson-jaxrs-json-provider-2.8.5.jar kafka_2.11-0.11.0.1.jar.asc scala-parser-combinators_2.11-1.0.4.jar jackson-module-jaxb-annotations-2.8.5.jar kafka_2.11-0.11.0.1-javadoc.jar slf4j-api-1.7.25.jar javassist-3.21.0-GA.jar kafka_2.11-0.11.0.1-javadoc.jar.asc slf4j-log4j12-1.7.25.jar javax.annotation-api-1.2.jar kafka_2.11-0.11.0.1-scaladoc.jar snappy-java-1.1.2.6.jar javax.inject-1.jar kafka_2.11-0.11.0.1-scaladoc.jar.asc validation-api-1.1.0.Final.jar javax.inject-2.5.0-b05.jar kafka_2.11-0.11.0.1-sources.jar zkclient-0.10.jar javax.servlet-api-3.1.0.jar kafka_2.11-0.11.0.1-sources.jar.asc zookeeper-3.4.10.jar javax.ws.rs-api-2.0.1.jar kafka_2.11-0.11.0.1-test.jar jersey-client-2.24.jar kafka_2.11-0.11.0.1-test.jar.asc [donald@Donald_Draper libs]$
从libs中的jar包来看，用到了aop，jackson，ws，snappy（压缩），zookeeper，slf4j-log4j，有kafka使用scala开发的，可以到scala相关的包。
