前言
提示:windows环境安装失败,Linux环境安装成功(以下并没有windows安装示例)
一、安装java(Kafka必须安装java,因为kafka依赖java核心)
下载地址:链接: https://www.oracle.com/java/technologies/downloads/
将文件放在Linux目录中后进行解压:
假设我把[jdk-20_linux-x64_bin.tar.gz]包放在了/root/src/uap/web/third 目录下1、tar -zxvf jdk-20_linux-x64_bin.tar.gz2、mv jdk.0.20 ./jdk3、vim /etc/profile JAVA_HOME=/root/src/uap/web/third/jdk PATH=/root/src/uap/web/third/jdk/bin:$PATH export JAVA_HOME4、source /ect/profile5、java -version (出现下图极为成功)
二、安装以及配置Kafka、zookeeper
1.下载Kafka(无需下载zookeeper,使用kafka自带的即可)
下载地址:https://kafka.apache.org/downloads
提示:不要下载带src的那个,具体我也不知道,因为我也是个小白
假设我把[kafka_2.12-3.5.1.tgz]包放在了/root/src/uap/web/third 目录下1、tar -zxvf kafka_2.12-3.5.1.tgz2、mv kafka.2.12 ./kafka3、创建kafka日志文件 mkdir -p ./kafka_data/log/kafka mkdir -p ./kafka_data/log/zookeeper mkdir -p ./kafka_data/zookeeper4、cd ./kafka/configvim server.properties listeners=PLAINTEXT://localhost:9092 (34行左右,添加对应的host、port) broker.id=0 port=9092 host.name=192.168.1.241 log.dirs=/root/src/uap/web/third/kafka_data/log/kafka zookeeper.connect=localhost:2181wdvim zookeeper.properties dataDir=/root/src/uap/web/third/kafka_data/zookeeper dataLogDir=/root/src/uap/web/third/kafka_data/log/zookeeper clientPort=2181 maxClientCnxns=100 tickTimes=2000 initLimit=10 syncLimit=5wd5、cd ../ 进入kafka目录下#启动zookeeper./bin/zookeeper-server-start.sh ./config/zookeeper.properties &//如果其中报错,大部分应该是报JAVA_HOME 这个说明你没有配置 /etc/profile 上面有./bin/kafka-server-start.sh -daemon ./config/server.properties &
2.配置topid
代码如下(示例):
kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic myt返回值:Created topic myt. 创建成功/否则失败
3.安装PHP的rdkafka,这个网上教程很多,基本上都是正确的
例如:阿里云开发者社区,php安装rdkafka教程
剩下逻辑就直接贴代码了
生产者:public function producer(){ $conf = new RdKafka\Conf(); $conf->set('metadata.broker.list', 'localhost:9092'); $producer = new RdKafka\Producer($conf); $topic = $producer->newTopic("mytest"); //获取数据库数据,存入kafka中 $wanchk = $this->db->query("SELECT * FROM hf_alarm_wanchk"); foreach ($wanchk as $k => $v){ $topic->produce(RD_KAFKA_PARTITION_UA, 0, array2json($v)); $producer->poll(0); } $result = $producer->flush(10000); if (RD_KAFKA_RESP_ERR_NO_ERROR !== $result) { throw new \RuntimeException('Was unable to flush, messages might be lost!'); } $producer->purge(RD_KAFKA_PURGE_F_QUEUE); $producer->flush(10000); }消费者://这个代码需要使用终端运行:// /bin/php -c /etc/php.ini -f /入口文件目录/index.php (类)consumer (方法)consumer public function consumer() { $conf = new \RdKafka\Conf(); $conf->set('group.id', 'mytest'); $rk = new \RdKafka\Consumer($conf); $rk->addBrokers("127.0.0.1"); $topicConf = new \RdKafka\TopicConf(); $topicConf->set('auto.commit.interval.ms', 100); $topicConf->set('offset.store.method', 'broker'); $topicConf->set('auto.offset.reset', 'smallest'); $topic = $rk->newTopic('mytest', $topicConf); $topic->consumeStart(0, RD_KAFKA_OFFSET_STORED); while (true) { $message = $topic->consume(0, 120 * 10000); switch ($message->err) { case RD_KAFKA_RESP_ERR_NO_ERROR: var_dump($message); break; case RD_KAFKA_RESP_ERR__PARTITION_EOF: echo "No more messages; will wait for more\n"; break; case RD_KAFKA_RESP_ERR__TIMED_OUT: echo "Timed out\n"; break; default: throw new \Exception($message->errstr(), $message->err); break; } } }
