连不上zk，很明显吧？

嗯嗯

启动ZooKeeper的时候会闪一个黑窗口出来，很快又不见了，是不是ZooKeeper启动失败啊？

没配zoo.conf吧，zk下载之后不配是跑不了的

# The number of milliseconds of each tick

# the directory where the snapshot is stored.

dataDir=/D:/zookeeper
# the port at which the clients will connect

# the maximum number of client connections.
# increase this if you need to handle more clients

#
# Be sure to read the maintenance section of the

#
# The number of snapshots to retain in dataDir

配置了，文件名字也修改了

是不是 dataDir 配置 存在问题啊
