安装 librdkafka
代码语言:javascript复制git clone https://github.com/edenhill/librdkafka.git ./librdkafka
cd ./librdkafka
./configure
# Or, to automatically install dependencies using the system's package manager:
# ./configure --install-deps
# Or, build dependencies from source:
# ./configure --install-deps --source-deps-only
make
sudo make install
使用 librdkafka
librdkafka 中自带 examples,cpp 目录下是 C 版本的包括两个 cpp 文件:consumer.cpp 和 producer.cpp,即生产者和消费者。修改其中 brokers
变量和 topic_str
变量的值。
consumer.cpp 文件的第58~63行修改如下(只修改了59行和61行,为看起来直观一些多粘了几行):
代码语言:javascript复制//broker 列表,可以用逗号隔开,只写其中一个也可以,这是线下测试环境
std::string brokers = "10.159.1.40:19092,10.159.1.41:19092,10.159.1.42:19092";
std::string errstr;
std::string topic_str="test_mq";
std::vector<std::string> topics;
topics.push_back(topic_str);
producer.cpp 文件的第31~34行修改如下(只修改了32行和34行,为看起来直观一些多粘了几行):
代码语言:javascript复制//broker 列表,可以用逗号隔开,只写其中一个也可以,这是线下测试环境
std::string brokers = "10.159.1.40:19092,10.159.1.41:19092,10.159.1.42:19092";
std::string errstr;
std::string topic_str="test_mq";
编译 consumer.cpp 和 producer.cpp
代码语言:javascript复制$ cd ~/librdkafka/examples/cpp
$ g -o consumer consumer.cpp -lrdkafka -lrdkafka -lstdc -lbaas_c_style_interface -I~/librdkafka/include -L~/librdkafka/lib
$ g -o producer producer.cpp -lrdkafka -lrdkafka -lstdc -lbaas_c_style_interface -I~/librdkafka/include -L~/librdkafka/lib
运行 producer 和 consumer (控制台交互式的程序,需要开两个窗口)
代码语言:javascript复制$ cd ~/librdkafka/examples/cpp
$ ./producer
% Created producer rdkafka#producer-1
hello world
% Produced message (11 bytes)
$ ./consumer
% Created consumer rdkafka#consumer-1
Read msg at offset 7
hello world
