修改 kafka-server-start.sh

3个节点都需要修改 kafka 启动文件
vim kafka-server-start.sh

export JMX_PORT="9999"

---
if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    export KAFKA_HEAP_OPTS="-Xmx1G -Xms1G"
fi
export JMX_PORT="9999"

EXTRA_ARGS=${EXTRA_ARGS-'-name kafkaServer -loggc'}

修改 kafka-run-class.sh

kafka-run-class.sh 修改 JMX 相关内容【-Djava.rmi.server.hostname=kafka_3】（行前边数字为行号，只是为了标识修改位置）：

...
213  # JMX port to use
214  if [  $JMX_PORT ]; then
215    KAFKA_JMX_OPTS="$KAFKA_JMX_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT -Djava.rmi.server.hostname=kafka_3"
216    if ! echo "$KAFKA_JMX_OPTS" | grep -qF -- '-Dcom.sun.management.jmxremote.rmi.port=' ; then
217      # If unset, set the RMI port to address issues with monitoring Kafka running in containers
218      KAFKA_JMX_OPTS="$KAFKA_JMX_OPTS -Dcom.sun.management.jmxremote.rmi.port=$JMX_PORT"
219    fi
220  fi
...

-Djava.rmi.server.hostname=kafka_3 其中 kafka_3 三台机器根据实际域名修改；
给 kafka-eagle/bin/ke.sh 赋予执行权限 chmod u+x bin/ke.sh
启动： ./bin/ke.sh start
admin/ 123456 :
输出如下：
