zookeeper安装( windows环境)

1.下载

Apache官方最新版本为:3.4.8
下载地址:http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz
下载后并解压到你指定的磁盘位置

2.将conf下的zoo_sample.cfg改名为zoo.cfg

之所以要这么做,是因为zookeeper默认的配置文件名就叫zoo.cfg

3.自定义zoo.cfg里的配置

# 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:\\zookeeper\\data  
dataLogDir=D:\\zookeeper\\log  
# 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 

1、tickTime:这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔,也就是每个 tickTime 时间就会发送一个心跳。
2、dataDir:顾名思义就是 Zookeeper 保存数据的目录,默认情况下,Zookeeper 将写数据的日志文件也保存在这个目录里。
3、dataLogDir:顾名思义就是 Zookeeper 保存日志文件的目录
4、clientPort:这个端口就是客户端连接 Zookeeper 服务器的端口,Zookeeper 会监听这个端口,接受客户端的访问请求。

4.查看bin目录下的zkEvn.cmd里的JAVA_HOME名字对不对

set JAVA="%JAVA_HOME%"\bin\java

如果这个名字与你之前安装JDK配置的环境变量的名字不对,那么就会因为找到JDK而报错

5.启动

需要注意的是,windows环境下需要启动的是windows命令脚 本,而不是shell命令脚本
这里写图片描述
双击zkServer.cmd,会启动一个java进程,即服务端
双击zkCli.cmd,会启动一个客户端
