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
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
