Zookeeper启动的问题

今天分享一个本地搭建Zookeeper的小问题

具体过程就是我打算在本地搭个Zookeeper玩玩，研究下ACL。去官网下载了Zookeeper-3.7.2,解压，复制配置文件修改为zoo.cfg,重新指定dataDir, dataLogDir, 然后，原神...咳咳，不好意思串戏了， 启动Zookeeper, 报错如下：

我看到 Unable to access,本能以为权限出问题了。但是我想想，我特么windows admin 啊，怎么会有权限问题？

这是我原本的配置文件：

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:\environment\tools\zookeeper-3.7.2\data
dataLogDir=D:\environment\tools\zookeeper-3.7.2\log
# the port at which the clients will connect
clientPort=2001
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#

看出问题在哪里了嘛？ 没错，就是路径中这个坑爹的 ""

我改成 "/" 就OK了

修改之后的配置文件如下：

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:/environment/tools/zookeeper-3.7.2/data
dataLogDir=D:/environment/tools/zookeeper-3.7.2/log
# the port at which the clients will connect
clientPort=2001
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60

启动成功！

出现这个问题的原因可能是，Zookeeper本身是通过java编写的，也是通过Java启动的，java读取配置文件反斜杠有特殊作用， 比如 \t是制表符等，所以才出现这个问题。

问题不大，但是说明还是要细心，路径中还是写"\"或者"/"更加合适。
