1.kafka安装

本地装了一套kafka的环境：

序号	名称	备注	下载链接
1	JDK1.8	Java开发环境	https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
2	Zookeeper3.7	分布式应用程序协调服务	http://mirror.bit.edu.cn/apache/zookeeper/
3	Kafka2.13	Kafka开发环境	http://kafka.apache.org/downloads.html

下载如下：

window下kafka安装及其使用

1.1安装JDK1.8

步骤1：双击安装包，直到安装完成，

步骤2：需要添加以下的环境变量（右键点击“我的电脑” -> "高级系统设置" -> "环境变量" ），如下：

JAVA_HOME: C:\Program Files\Java\jdk1.8.0_171 (jdk的安装路径)

Path: 在现有的值后面添加"; %JAVA_HOME%\bin"

步骤3：1.3 打开cmd运行 "java -version" 查看当前系统Java的版本：

1.2安装Zookeeper3.7

步骤1：解压安装包apache-zookeeper-3.7.0-bin.tar.gz，

步骤2：打开zookeeper-3.4.13\conf，把zoo_sample.cfg重命名成zoo.cfg，从文本编辑器里打开zoo.cfg，把dataDir的值改成“./zookeeper-3.4.13/data”

步骤3：添加如下系统变量：

ZOOKEEPER_HOME: D:\kafkaPrestduy\apache-zookeeper-3.7.0-bin (zookeeper目录)

Path: 在现有的值后面添加 ";%ZOOKEEPER_HOME%\bin;"

1.3 Kafka2.13安装

步骤1：kafka_2.13-3.1.0.tgz解压

步骤2：打开kafka_2.11-2.0.0\config，从文本编辑器里打开 server.properties。把 log.dirs的值改成 “./logs”

2.命令行测试

步骤1：启动zookeeper，进入目录：D:\kafkaPrestduy\apache-zookeeper-3.7.0-bin\bin

执行如下：./zkserver

步骤2：启动kafka，进入目录：D:\kafkaPrestduy\kafka_2.13-3.1.0\bin\windows

启动服务： ./kafka-server-start.bat ..\..\config\server.properties

window下kafka安装及其使用

创建话题：

.\kafka-topics.bat --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic test

创建生产者：

kafka-console-producer.bat --broker-list localhost:9092 --topic test

创建消费者：

kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning

window下kafka安装及其使用

查看话题：

./kafka-topics.bat --list --bootstrap-server localhost:9092

3.客户端程序开发

librdkafka依赖openssl，zlib与zstd库，所以先编译依赖，然后编译librdkafka

各个库使用版本：

库名	下载地址
openssl-1.0.2a	/index.html
librdkafka-1.4.x	https://github.com/edenhill/librdkafka
zlib	NuGet获取（解决方案右键->获取NuGet）
zstd	NuGet获取（解决方案右键->获取NuGet）

备注：zlib与zstd：D:\kafkaPrestduy\librdkafka-1.4.x\librdkafka-1.4.x\win32\packages

3.1 openssl编译

OpenSSL编译在vs2019，首先下载/index.html下，找并下载：openssl-1.0.2a

步骤1：下载编译环境Perl和NASM，双击安装即可

Download & Install Perl - ActiveState

https://www.nasm.us/pub/nasm/releasebuilds/2.14rc15/win64/nasm-2.14rc15-installer-x64.exe

步骤2：编译方式选择：在此x64的release版本：perl Configure VC-WIN64A

编译类别	平台	编译指令
debug	x86	perl Configure debug-VC-WIN32 --prefix=xxx
debug	x64	perl Configure debug-VC-WIN64A --prefix=xxx
release	x86	perl Configure VC-WIN32 --prefix=xxx
release	x64	perl Configure VC-WIN64A --prefix=

注意：没有安装nasm，加上no-asm

--prefix参数：库生成目录

步骤3：创建 makefile 文件

创建32位makefile文件：ms\do_ms.bat

创建64位makefile文件 ms\do_win64a.ba

步骤4：编译动态库和静态库

编译动态库：

nmake -f ms\ntdll.mak

nmake -f ms\ntdll.mak test

nmake -f ms\ntdll.mak install

编译静态库：

lib nmake -f ms\nt.mak

nmake -f ms\nt.mak test

nmake -f ms\nt.mak install

备注:重新编译需要：

nmake -f ms\nt.mak clean

nmake -f ms\ntdll.mak clean

步骤5:在指定的目录下获取到库文件

3.2 librdkafka编译

步骤1：https://github.com/edenhill/librdkafka，下载并解压

步骤2：\librdkafka-1.4.x\win32\librdkafka.sln下使用vs2019打开

步骤3：编译librdkafka项目,点击编译，报错如下：

Error This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them. For more information, see 必应

解决方法：

找到项目文件librdkafka.csproj，打开后，移除下面：

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
  <PropertyGroup>
    <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
  </PropertyGroup>
  <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
</Target>

2.zlib和zstd连接失败

在\librdkafka-1.4.x\win32\packages目录下，有zlib和libzstd编译好的库，只添加包含头文件和附加库目录，以及链接lib文件。

Zlib头文件：

\librdkafka-1.4.x\win32\packages\zlib.v140.windesktop.msvcstl.dyn.rt-dyn.1.2.8.8\build\native\include

zlib库文件：

librdkafka-1.4.x\win32\packages\zlib.v140.windesktop.msvcstl.dyn.rt-dyn.1.2.8.8\lib\native\v140\windesktop\msvcstl\dyn\rt-dyn\x64\Release

libzstd头文件：

\librdkafka-1.4.x\win32\packages\confluent.libzstd.redist.1.3.8-g9f9630f4-test1\build\native\include

Libzstd库文件：

\librdkafka-1.4.x\win32\packages\confluent.libzstd.redist.1.3.8-g9f9630f4-test1\build\native\lib\win\x64

3.确实openssl缺失

找到opensssl编译生成目录，添加包含头文件和附加库目录，以及链接lib文件

步骤4：编译libkafka，文件生产在\librdkafka-1.4.x\win32\outdir\v142\x64\Release
