8.2 Zookeeper下载与安装

---

ZooKeeper服务器是用Java创建的，它在JVM上运行。需要使用JDK 6或更高版本。这里我们使用JDK8，前文已经安装。

8.2.1 Zookeeper下载

Zookeeper官网：http://zookeeper.apache.org 
在首页“Getting Started”区域找到”download”链接 

在新页面中再次单击”download”链接，将跳转到下载页面http://www.apache.org/dyn/closer.cgi/zookeeper/

请单击国内的链接地址进行下载。 
此处下载了截至2017年6月27日止最新稳定版zookeeper-3.4.10.tar.gz。

8.2.2 Zookeeper安装

将刚才下载的zookeeper-3.4.10.tar.gz软件包上传到node1节点 

解压缩到/opt目录

[root@node1 app]# tar -zxvf zookeeper-3.4.10.tar.gz /opt

修改zookeeper解压缩目录的所有者

[root@node1 opt]# ll
