windows下kafka的環境配置及rdkafka庫的應用

1、下載並安裝Win32OpenSSL-1_0_2s
2、從github上下載代碼：
https://github.com/edenhill/librdkafka/tree/v0.11.6-RC4，解壓並用vs2017打開win32/librdkafka.vcxproj工程文件
3、選中librdkafka工程，右鍵屬性-Platform Toolset，改爲Visual Stdio 2015（v140）
4、找到regexp.c文件，在開始部分添加代碼：

#if _MSC_VER>=1900
#include "stdio.h" 
_ACRTIMP_ALT FILE* __cdecl __acrt_iob_func(unsigned);
#ifdef __cplusplus 
extern "C"
#endif 
FILE* __cdecl __iob_func(unsigned i) {
	return __acrt_iob_func(i);
}
#endif /* _MSC_VER>=1900 */

5、編譯代碼
6、選中librdkafkacpp工程後，照步驟4修改平臺工具集爲Visual Stdio 2015(v140)
7、編譯librdkafkacpp代碼，此時rdfkafka已經算編譯成功了。
8、將rdkafka.h和rdkafkacpp.h移動到新建的inc目錄，將librdkafka.lib，librdkafkacpp.lib移動到lib文件夾下，爲下面的c++ kafka應用作準備。
9、新建rdkafka的producer工程，寫producer相關代碼：

#include <iostream>
#include <string>
#include <cstdlib>
#include <cstdio>
#include <csignal>
#include <cstring>

#include <getopt.h>

#include "rdkafkacpp.h"

static bool run = true;

static void sigterm(int sig) {
	run = false;
}

class ExampleDeliveryReportCb : public RdKafka::DeliveryReportCb {
public:
	void dr_cb(RdKafka::Message &message) {
		std::cout << "Message delivery for (" << message.len() << " bytes): " <<
			message.errstr() << std::endl;
		if (message.key())
			std::cout << "Key: " << *(message.key()) << ";" << std::endl;
	}
};

class ExampleEventCb : public RdKafka::EventCb {
public:
	void event_cb(RdKafka::Event &event) {
		switch (event.type())
		{
		case RdKafka::Event::EVENT_ERROR:
			std::cerr << "ERROR (" << RdKafka::err2str(event.err()) << "): " <<
				event.str() << std::endl;
			if (event.err() == RdKafka::ERR__ALL_BROKERS_DOWN)
				run = false;
			break;

		case RdKafka::Event::EVENT_STATS:
			std::cerr << "\"STATS\": " << event.str() << std::endl;
			break;

		case RdKafka::Event::EVENT_LOG:
			fprintf(stderr, "LOG-%i-%s: %s\n",
				event.severity(), event.fac().c_str(), event.str().c_str());
			break;

		default:
			std::cerr << "EVENT " << event.type() <<
				" (" << RdKafka::err2str(event.err()) << "): " <<
				event.str() << std::endl;
			break;
		}
	}
};

int main()
{
	std::string brokers = "localhost";
	std::string errstr;
	std::string topic_str = "test";
	int32_t partition = RdKafka::Topic::PARTITION_UA;

	RdKafka::Conf *conf = RdKafka::Conf::create(RdKafka::Conf::CONF_GLOBAL);
	RdKafka::Conf *tconf = RdKafka::Conf::create(RdKafka::Conf::CONF_TOPIC);

	conf->set("bootstrap.servers", brokers, errstr);

	ExampleEventCb ex_event_cb;
	conf->set("event_cb", &ex_event_cb, errstr);

	signal(SIGINT, sigterm);
	signal(SIGTERM, sigterm);

	ExampleDeliveryReportCb ex_dr_cb;
	conf->set("dr_cb", &ex_dr_cb, errstr);

	RdKafka::Producer *producer = RdKafka::Producer::create(conf, errstr);
	if (!producer) {
		std::cerr << "Failed to create producer: " << errstr << std::endl;
		exit(1);
	}
	std::cout << "% Created producer " << producer->name() << std::endl;

	RdKafka::Topic *topic = RdKafka::Topic::create(producer, topic_str,
		tconf, errstr);
	if (!topic) {
		std::cerr << "Failed to create topic: " << errstr << std::endl;
		exit(1);
	}

	for (std::string line; run && std::getline(std::cin, line);) {
		if (line.empty()) {
			producer->poll(0);
			continue;
		}

		RdKafka::ErrorCode resp =
			producer->produce(topic, partition,
				RdKafka::Producer::RK_MSG_COPY /* Copy payload */,
				const_cast<char *>(line.c_str()), line.size(),
				NULL, NULL);
		if (resp != RdKafka::ERR_NO_ERROR)
			std::cerr << "% Produce failed: " <<
			RdKafka::err2str(resp) << std::endl;
		else
			std::cerr << "% Produced message (" << line.size() << " bytes)" <<
			std::endl;

		producer->poll(0);
	}

	run = true;
	// 退出前處理完輸出隊列中的消息
	while (run && producer->outq_len() > 0) {
		std::cerr << "Waiting for " << producer->outq_len() << std::endl;
		producer->poll(1000);
	}

	delete conf;
	delete tconf;
	delete topic;
	delete producer;

	RdKafka::wait_destroyed(5000);

	return 0;
}

完成後將步驟6的inc和lib目錄添加進工程配置裏面，然後編譯代碼。（如果報找不到librdkafka.dll或者librdkafkacpp.dll，就將對應的dll拷貝到Debug\Release的生成文件目錄中。）
8、下載jdk，配置java環境變量JAVA_HOME及PATH
9、下載zookeeper-3.4.14.tar，解壓後複製zoo_sample.cfg重命名成zoo.cfg，修改編輯zoo.cfg，修改dataDir爲【dataDir=/data】
10、添加環境變量

   ZOOKEEPER_HOME          D:\Program Files\zookeeper-3.5.2-alpha
   Path 在現有的值後面添加     ;%ZOOKEEPER_HOME%\bin;

11、運行zookeeper：zkserver
12、下載kafka_2.12-2.3.0，解壓後打開目錄D:\kafka_2.12-0.11.0.0\config下server.properties文件，把log.dirs修改爲【log.dirs=D:\kafka-logs】
12、運行kafka集羣環境：.\bin\windows\kafka-server-start.bat .\config\server.properties
13、運行kafka的producer：.\bin\windows\kafka-console-producer.bat --broker-list localhost:9092 --topic test
14、運行kafka的customer：.\bin\windows\kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic test --from-beginning
15、在producer的cmd裏面寫消息內容，可以看到customer的cmd接收到了消息。
16、啓動步驟9的rdkafka的producer程序（程序中端口設置爲9092，ip設置爲licalhost，topic設置爲test），在啓動窗口發送消息，可以看到customer的cmd裏面接收到了消息。
