Kafka Standy模式、创建主题，生产消费消息

Kafka配置文件：http://donald-draper.iteye.com/blog/2397000
Quickstart:http://kafka.apache.org/quickstart
上面我们简单看了一下kafka的相关配置，今天我们启动standy模式的kafka，即单机版，并使用相关命令创建topic，
生产消息和消费消息。
1.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/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；
2.启动服务器

由于kafka需要使用Zookeeper，所以你需要先启动Zookeeper，如果没有Zookeeper，可以使用kafka内部自带的Zookeeper。

[donald@Donald_Draper bin]$ ./zookeeper-server-start.sh ../config/zookeeper.properties &

[donald@Donald_Draper bin]$ 

我们可以通过kafka-topics命令查看topic信息,具体如下:

[donald@Donald_Draper bin]$ ./kafka-topics.sh --list --zookeeper localhost:2181
[2017-10-21 17:23:13,183] INFO Accepted socket connection from /127.0.0.1:53312 (org.apache.zookeeper.server.NIOServerCnxnFactory)

[2017-10-21 17:23:13,255] INFO Closed socket connection for client /127.0.0.1:53312 which had sessionid 0x15f3e3b9f1b0002 (org.apache.zookeeper.server.NIOServerCnxn)
[donald@Donald_Draper bin]$ 

从上面来看，有一个test主题。

另外，除了手工创建topic外，你也可以配置你的broker，当发布一个不存在的topic时自动创建topic。

4.生产消息

Kafka提供了一个命令行的工具，可以从输入文件或者命令行中读取消息并发送给Kafka集群。每一行是一条消息。
运行producer（生产者）,然后在控制台输入几条消息到服务器。

[donald@Donald_Draper bin]$ ./kafka-console-producer.sh --broker-list localhost:9092 --topic test
>my name is donald.
>hello!

5.消费消息

Kafka也提供了一个消费消息的命令行工具，将存储的信息输出出来。
重新启动一个终端，用于消费者消费消息：

[donald@Donald_Draper bin]$ ./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
my name is donald.
hello!

如果你有2台不同的终端上运行上述命令，那么当你在运行生产者时，消费者就能消费到生产者发送的消息。
我们在生产者终端生产消息，在消息者终端消费消息。

在生产者终端继续生产如下消息：

[donald@Donald_Draper bin]$ ./kafka-console-producer.sh --broker-list localhost:9092 --topic test
>my name is donald.
>hello!
>what's your name?
>

消息者终端显示如下：

[donald@Donald_Draper bin]$ ./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning
my name is donald.
hello!
what's your name?

所有的命令行工具有很多的选项，可以运行无参数命令，查看命令文档来了解更多的功能。

比如kafka-topics命令:

[donald@Donald_Draper bin]$ ./kafka-topics.sh
Create, delete, describe, or change a topic.

删除topic命令：

[donald@Donald_Draper bin]$ ./kafka-topics.sh --delete --zookeeper localhost:2181 --topic test
Topic test is marked for deletion.4.生产发送消息
Note: This will have no impact if delete.topic.enable is not set to true.
[donald@Donald_Draper bin]$ 

再次浏览topic：

[donald@Donald_Draper bin]$ ./kafka-topics.sh --list --zookeeper localhost:2181
__consumer_offsets
test
[donald@Donald_Draper bin]$ 

从上面的输出来看，我们并没有删除test topic主要是因为我们没有开启broker的如下配置：

# Switch to enable topic deletion or not, default value is false
是否可以删除topic，如果为true，我们可以在命令行删除topic，否则，不能。
#delete.topic.enable=true

上面的操作我们启动的使standy模式，下面我们来，搭建一个kafka集群。
在搭建集群之前，先关闭原先的standy kafka：

[donald@Donald_Draper bin]$ ./kafka-server-stop.sh ../config/server.properties 
[donald@Donald_Draper bin]$ ./zookeeper-server-stop.sh  ../config/zookeeper.properties 

kafka集群，我们放在下一篇来讲。
