dataLogDir：顾名思义就是 Zookeeper 保存日志文件的目录
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。

当这些配置项配置好后，你现在就可以启动 Zookeeper 了，启动后要检查 Zookeeper 是否已经在服务，可以通过 netstat – ano 命令查看是否有你配置的 clientPort 端口号在监听服务</pre><p></p><p>单机安装非常简单，只要获取到 Zookeeper 的压缩包并解压到某个目录如：D:\Java\Tool\zookeeper-3.4.6下，Zookeeper 的启动脚本在 bin 目录下，Windows 下的启动脚本是bin文件下的如，D:\Java\Tool\zookeeper-3.4.6\bin\ zkServer.cmd。</p><p>启动如下：</p><p align="center"><img src="http://img.blog.csdn.net/20150827140429526" alt=""><br></p><p align="center">输入JPS，出现如下，也说明启动成功</p><p style="text-align: center;"><img src="http://img.blog.csdn.net/20150823110117879" alt=""><br></p><p><br></p><p>上面的黑色框框不关，就表示注册中心一直开关的，一定要记得注册中心要在程序运行之前就打开，而且是一直开着的</p><h1><a name="t1"></a>二、Dubbo-admin管理平台的安装</h1><h2><a name="t2"></a>1.1、dubbo-admin 本地编译打包</h2><p>        因为zookeeper只是一个黑框，我们无法看到是否存在了什么提供者或消费者，这时就要借助Dubbo-Admin管理平台来实时的查看，也可以通过这个平台来管理提者和消费者。<br><span style="color:#ff0000;"><strong>        dubbo-admin.war可在网上百度去下载，但是我下载了好几个war包，发布上去服务启动都报错，这个时候大概是我们系统的JDK和编译dubbo-admin.war的JDK版本不同导致的了。所以我之后直接下载了dubbo-master的源代码，然后自己编译了一个war包，这样就不会存在启动报错的问题了。（这里强烈建议自己编译一个，网上找的基本都不行，试了很多个，最后还是自己来搞）其中自己电脑编译的过程如下，一定在安装maven和jdk!</strong></span></p><p>dubbo的所有源码可在https://github.com/alibaba/dubbo上下载。下好之后解压</p><p style="text-align: center;"><img src="http://img.blog.csdn.net/20150827140751652" alt=""><br></p><p>解压后的文件内容，这里你其它的都不用去管，只管dubbo-admin.</p><p style="text-align: center;"><img src="http://img.blog.csdn.net/20150827141527417" alt=""><br></p><p><span style="color:#ff0000;"><strong>因为这里只需要编译Dubbo-Admin，所以打开Cmd,然后进入解压路径 E:\下载\dubbo-master\dubbo-master\dubbo-admin,有人把整个工程都编译了，其实没有必要，只需要编译dubbo-admin即可，有什么依赖的，maven会自动帮你解决。整个过程如下：</strong></span></p><p><span style="color:#ff0000;"><strong>首先，通过cmd进入目录，输入命令</strong></span></p><p style="text-align: center;"><img src="http://img.blog.csdn.net/20150827141024607" alt=""><br></p><p>然后输入命令</p><p></p><div class="dp-highlighter bg_html"><div class="bar"><div class="tools"><b>[html]</b> <a href="#" class="ViewSource" title="view plain" onclick="dp.sh.Toolbar.Command('ViewSource',this);return false;">view plain</a><span data-mod="popu_168"> <a href="#" class="CopyToClipboard" title="copy" onclick="dp.sh.Toolbar.Command('CopyToClipboard',this);return false;">copy</a><div style="position: absolute;
