kafka manger 报错java.rmi.ConnectException: Connection refused to host: 127.0.0.1

百度不到，bing上搜到这篇，参考这个解决就可以

https://github.com/yahoo/kafka-manager/issues/214

kafka-run-class.sh中

# JMX settings
if [ -z "$KAFKA_JMX_OPTS" ]; then
  KAFKA_JMX_OPTS="-Djava.rmi.server.hostname=192.168.6.11 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false  -Dcom.sun.management.jmxrem
ote.ssl=false "
fi

增加一项-Djava.rmi.server.hostname=192.168.6.11 就可以了
