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！
