Zookeeper - zookeeper安装与配置

1、什么时Zookeeper

ZooKeeper：分布式服务框架 Zookeeper -- 管理分布式环境中的数据。

2、安装

1》官网下载压缩包并解压zookeeper-3.4.14.zip

2》在zookeeper-3.4.14的Home目录新建data、log文件夹

3》进入conf目录，复制其中的zoo_sample.cfg文件到同级目录，重命名为zoo.cfg（Zookeeper 在启动时会找这个文件作为默认配置文件）。修改其中的dataDir、dataLogDir

...
# example sakes.
dataDir=F:\\ebook\\Dubbo\\zookeeper-3.4.14\\data
dataLogDir=F:\\ebook\\Dubbo\\zookeeper-3.4.14\\log
# the port at which the clients will connect
...

3、启动测试
