不知楼主是采用kafka中的zookeeper还是重新安装了zookeeper服务。不过不影响，都可以使用。
1.看日志打印，zookeeper服务已经启动，处于CONNECTING状态，
2.看下kafka的config/server.properties 配置文件中ip和端口是否填写正确。
特别是监听的zookeeper端口配置处，这个需要和zookeeper提供的监听端口对应。
3，如果楼主（2）步中确定了没有问题，那么再看看你的数据（kafka俗称日志）文件目录是否已经建立。
LZ如果看了，kafka还是起不来，可以发出来我帮你看看。若有帮助，还望采纳！！！！谢谢
请问这个怎么解决的，我也是遇到这个问题了
