All Kafka configuration files are stored in the $KAFKA_HOME/config directory.

1. Go to the Kafka configuration directory.

2. Modify the server.properties file.

      broker.id=0 port=6667 host.name=agent1 log.dirs=/data/data1/kafka,/data/data2/kafka,/data/data3/kafka,/data/data4/kafka,/data/data5/kafka,/data/data6/kafka,/data/data7/kafka,/data/data8/kafka,/data/data9/kafka,/data/data10/kafka,/data/data11/kafka,/data/data12/kafka zookeeper.connect=agent1:2181,agent2:2181,agent3:2181

      

      In the preceding command, set host.name to the IP address of agent1 and log.dirs to the actual data storage path.
