一、下载及安装配置 JDK (Kafka依赖于Zookeeper服务,而Zookeeper的运营依赖JDK)
1.地址:https://www.oracle.com/java/technologies/javase-jdk14-downloads.html
下载windows可执行文件,直接点击安装,默认下一步,直到完成安装。
2.配置JDK
我的电脑 --> 右键 ---> 属性 --> 高级系统设置 -- > 环境变量
添加 JAVA_HOME变量:C:\Program Files\Java\jdk-14.0.2
添加 CLASSPATH变量:%JAVA_HOME%\lib
在PATH变量中加入:%JAVA_HOME%\bin
打开CMD,验证JDK是否安装成功
二、下载安装配置 Zookeeper服务
1.地址:https://mirror-hk.koddos.net/apache/zookeeper/stable/
2.修改配置文件:conf 文件夹,在里面复制一份zoo_sample.cfg并重命名为zoo.cfg文件。
(这里我主要修改了日志存储地址:dataDir)
# 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:\\AmandaSoft\\apache-zookeeper-3.5.8-bin\\data # 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
配置文件简单解析
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.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。
3.进入..\apache-zookeeper-3.5.8-bin\bin目录
会出现以下很长一段:可以看到QuorumPeerMain的进程
可通过双击 zkCli.cmd启动客户端
