 *  dubbo-admin简单使用

**1、node下载和安装**

dubbo-admin 是一个前后端分离的项目。前端使用vue，后端使用springboot，安装 dubbo-admin 其实就是部署该项目。我们将dubbo-admin安装到开发环境上。要保证开发环境有jdk，maven，nodejs

安装node

因为前端工程是用vue开发的，所以需要安装node.js，node.js中自带了npm，后面我们会通过npm启动

下载地址

https://nodejs.org/en/

一路点击下一步进行安装node (无需关心环境变量选择的那一步，默认第一个即可，会自动添加到环境变量)，使用如下命令查看是否安装成功

**3、把下载的zip包解压到指定文件夹(解压到那个文件夹随意)**

![\[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-mCPOfH3k-1610961439904)(images\\1578297477356.png)\]][img-mCPOfH3k-1610961439904_images_1578297477356.png]

**4、修改配置文件**

解压后我们进入如下目录，找到 **application.properties** 配置文件 进行配置修改

**5、打包项目**

在 dubbo-admin-develop 目录执行打包命令

按住shift点右键，使用powershell，执行如下指令，需要提前安装maven

此过程时间较长，需要20分钟左右，期间可能会报错误和警告，属于正常现象

mvn  clean package

执行结束后的效果如下图：

用户名密码都是root

# dubbo-admin简单使用 #

1.  查询

在上面的步骤中，我们已经进入了Dubbo-Admin的主界面

输入\*可查询所有的服务

图示为dubbo学习笔记中的服务 (需要先将此生产者服务启动)

点击详情后

![\[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-LLSZT2qG-1610961439925)(C:\\Users\\GAOqize\\Desktop\\Dubbo & Zookeeper\\课件\\4.Dubbo\\20-Dubbo\\资料\\dubbo-admin安装.assets\\image-20210118170830219.png)\]][img-LLSZT2qG-1610961439925_C_Users_GAOqize_Desktop_Dubbo _ Zookeeper_4.Dubbo_20-Dubbo_dubbo-admin_.assets_image-20210118170830219.png]

如果要显示成功元数据，需要在生产者的xml配置文件中添加如下代码

<dubbo:metadata-report address="zookeeper://192.168.149.135:2181" />

重新启动生产者，再次打开Dubbo-Admin

这样我们的元数据信息就出来了
