把以下内容追加到bashrc中。
以centos为例:
vi ~/.bashrc
追加内容如下:
KAFKA_HOME="/usr/lib/kafka" KAFKA_ADDRESS="192.168.108.136" KAFKA_BIND="${KAFKA_ADDRESS}:9092" ZK_BIND="${KAFKA_ADDRESS}:2181" alias listtopics="${KAFKA_HOME}/bin/kafka-topics.sh --list --zookeeper ${ZK_BIND} " alias createtopic="${KAFKA_HOME}/bin/kafka-topics.sh --create --zookeeper ${ZK_BIND} --replication-factor 1 --partitions 1 --topic " alias kafkaproduce="${KAFKA_HOME}/bin/kafka-console-producer.sh --broker-list ${KAFKA_BIND} --topic " alias kafkaconsume="${KAFKA_HOME}/bin/kafka-console-consumer.sh --zookeeper ${ZK_BIND} --from-beginning --topic " alias kafkaconsumekey="${KAFKA_HOME}/bin/kafka-console-consumer.sh --zookeeper ${ZK_BIND} --from-beginning --property print.key=true --property key.separator=' --- ' --topic " alias kafkaconsumeoffset="${KAFKA_HOME}/bin/kafka-console-consumer.sh --zookeeper ${ZK_BIND} --from-beginning --print-offsets --topic"
