centos 7下安装配置dubbo-admin

1、安装好tomcat之后，
下载并且编译最新的dubbo-admin 如图：




1、修改WEB-INF中的dubbo.properties
dubbo.registry.address=zookeeper://192.168.1.87:2181//zookeeper的地址
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest
2、删除原tomcat/webapps/ROOT目录下的所有文件，同时复制dubbo-admin解压后的内容到tomcat/webapps/ROOT中
3、启动tomcat
4、访问对应的ip地址
如果出现：

这些错误

原来是我用的jdk版本太高，jdk8, dubbo默认用的spring版本比较旧，冲突导致，作如下修改即可
1、webx的依赖改为3.1.6版；

<dependency>
<groupId>com.alibaba.citrus</groupId>
<artifactId>citrus-webx-all</artifactId>
<version>3.1.6</version>
</dependency>

2、添加velocity的依赖，我用了1.7；

<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity</artifactId>
<version>1.7</version>
</dependency>

3、对依赖项dubbo添加exclusion，避免引入旧spring

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>${project.parent.version}</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
</exclusion>
</exclusions>
</dependency>

4、webx已有spring 3以上的依赖，因此注释掉dubbo-admin里面的spring依赖

<!--<dependency>-->
<!--<groupId>org.springframework</groupId>-->
<!--<artifactId>spring</artifactId>-->
<!--</dependency>-->

重新编译dubbo放tomcat运行，成功启动！
