刚从kafka官网上下载的kafka_2.11-2.1.0，按官网上的教程，解压然后启动zookeeper在启动Zookeeper时，停止在INFO binding to port 0.0.0.0/0.0.0.0:21(org.apache.zookeeper.server.NIOServerCnxnFactory)不动了。

恭喜你，成功了，这个是会话前端保持的，你加&可以后台运行。
在哪里加&？启动命令？bin/zookeeper-server-start.sh config/zookeeper.properties
我刚接触，对这块不太懂
nohup bin/zookeeper-server-start.sh config/zookeeper.properties &
nohup: 忽略输入并把输出追加到"nohup.out"
[2]+ 退出 1 nohup bin/zookeeper-server-start.sh config/zookeeper.properties
运行结果，好像没成功啊，telnet端口没通
看下nohup.out里面打印的什么

这是通了吗？
嗯。zk启动成功了
好的，非常感谢。困扰了我一天，原来是启动成功了的。新手上路。。。
客气了，结贴吧。
