Question

我是使用Zookeeper并尝试使用Zookeeper本书学习它的新手。现在，要以独立模式启动服务器，请在书中给出使用命令bin/zkServer.sh start。

我正在使用Windows，因此我将命令作为bin/zkServer.cmd start运行，现在我收到一个奇怪的错误：

D:\zoo\zookeeper-3.4.6>bin\zkServer.cmd start

D:\zoo\zookeeper-3.4.6>java "-Dzookeeper.log.dir=D:\zoo\zookeeper-3.4.6\bin\.." "-Dzookeeper.root.logger=INFO,CONSOLE" -cp "D:\zoo\zookeeper-3.4.6\bin\..\build\classes;D:\zoo\zookeeper-3.4.6\bin\..\b

D:\zoo\zookeeper-3.4.6>endlocal

有人可以帮助我理解为什么我会收到此错误吗？命令已经从这本Zookeeper书中提到的内容发生了变化？

在浏览了这篇SO zookeeper not starting之后，我可以通过省略命令的输入start来使动物园管理员工作。这是在独立模式下启动服务器的正确方法吗？

这是我对zookeeper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=/tmp/zookeeper
dataDir=D:\dataDir
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

Answer 1

Zookeeper 3.4.6可能会有一些变化。对于此版本，启动服务器如下所示：

仓\ zkServer.cmd

E.g。

D:\zoo\zookeeper-3.4.6>bin\zkServer.cmd

注意，您不需要传递命令行arg＆＃34; start＆＃34;

Answer 2

可能有两种可能

Zookeeper 3.4.6 中的变化。对于这个版本，启动服务器如下图所示：

bin\zkServer.cmd

hello world °

MyID 文件中可能有空格例如D:\zoo\zookeeper-3.4.6>bin\zkServer.cmd 改成
