dubbo入门(一):ubuntu14.04 jdk8下 dubbo-admin编译安装

本文环境：ubuntu14.04 jdk1.8.0_91 intellij idea

第一步编译dubbo-admin

我刚试了http://dubbo.io/的安装方法 发现一些源已经无法访问了 所以就用编译安装的方法
这是阿里dubbo的github https://github.com/alibaba/dubbo
把源码下载下来后 用mvn编译会有各种问题 所以用intellij打开后在mavenproject里将dubbo-admin的pom.xml导入

去掉test的勾选
y由于我用的是jdk8 原先下载下来的pom.xml会有点问题 需要进一步修改

改完之后 点击package打包一个dubbo-admin的war出来

第二步是安装zookeeper

dubbo本身应该是一个rpc也就是远程调度框架 如果我们分布式服务单纯只是做成一些各个服务的接口 供另一些服务器curl 获得json等等
那么当服务接口越来越多，甚至需要对每个服务的服务器进行负载均衡时，我们这些服务的接口将变得非常难以维护
所以我们需要zookeeper来作为服务注册中心 帮我们管理各个服务的服务器集群 我们只需要跟zookeeper拿服务接口即可～

http://apache.fayea.com/zookeeper/
下载完后写一个zoo.cfg 然后用bin/zkServer.sh start启动即可

第三步是部署刚才的war到tomcat中

这个简单啦
在war解压后的文件目录的WEB-INF里可以看到一个dubbo.properties
里面有dubbo-admin的管理员账号密码
登陆后看到如下 搞定
