dubbo-admin 2.5.4 编译和部署

转自: http://blog.51cto.com/morrowind/1933538


前言:

    公司比较奇葩,应用服务器用的还是老版本的resin、jboss这些。由于原有dubbo-admin无法访问,就想用tomcat重新部署套。官网dubbo.io提供的下载地址已经无法下载,那就用源码编译吧。

环境:

    系统:linux

    maven:3.5.0

    java:1.7.0_80

问题:

    git clone https://github.com/alibaba/dubbo.git

    git完源码后,以为按照github上的说明一步一步来就可以编译成功,其实不然。官方文档没有说明java版本,而说明的maven版本是2.2,mvn install 一直报错,加了-X参数后看到一些详细信息,但搜索到的都是说java版本问题。


解决:

    于是将java版本从1.6-1.8都试了,但还是一样的错误……无果,于是找了位开发,让其帮build下,结果……居然成功了,但启tomcat时又是各种错,就问了下开发的编译环境:

    maven:3.5+

    java:1.8+


    这次查tomcat日志信息确实是java版本的问题了,但不是tomcat使用的java版本,而是build dubbo时使用的java版本问题,build dubbo时不能使用java1.8+的版本。于是使用java1.7 自己重新build了下,在放到tomcat中运行,可以正常访问了


插曲:

    看到网上有人说直接到duboo-admin目录下mvn package -Dmaven.skip.test=true 就可以打包成功,但我这报错,错误信息如下:

想着应该是没有编译dubbo的问题导致缺少依赖jar,于是到dubbo主目录,将dubbo全编译了下,看到成功后,在dubbo-admin/target 下就生成了需要的dubbo-admin-2.5.4-SNAPSHOT.war文件。这时可将dubbo-admin-2.5.4-SNAPSHOT目录内的文件直接放到tomcat的ROOT目录下,修改dubbo.properties文件内的zookeeper

集群方式为

1
2
3
dubbo.registry.address=zookeeper://ip_1:2181?backup=ip_2:2181,ip_3:2181
dubbo.admin.root.password=root
dubbo.admin.guest.password=guest


验证:

    浏览器访问tomcat地址,用root或guest登录,页面如下
