/*启动kafka服务*/

依次执行：

启动zookeeper

常规模式启动

bin/zookeeper-server-start.sh config/zookeeper.properties

进程守护模式启动

nohup bin/zookeeper-server-start.sh config/zookeeper.properties >/dev/null 2>&1 &

启动kafka

常规模式启动

bin/kafka-server-start.sh config/server.properties

进程守护模式启动

nohup bin/kafka-server-start.sh config/server.properties >/dev/null 2>&1 &

/*关闭kafka服务*/

关闭kafka

bin/kafka-server-stop.sh

关闭zookeeper

bin/zookeeper-server-stop.sh

./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic ****

/*创建生产者*/

./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic ****
