ZooKeeper集群status报错，换行符惹的祸

配置好ZK集群后，发现启动成功，但是使用status查看状态时，报错：

sh zookeeper/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /data/test/zookeeper/bin/../conf/zoo.cfg
myid could not be determined, will not able to locate clientPort in the server configs.
. Client address: localhost. Client SSL: false.
Error contacting service. It is probably not running.

经排查，发现是zoo.cfg这个文件的换行符是\r\n，所以要把这个文件的换行符改为\n
