实战案例：二进制安装 dubbo-admin

新版用Golang重构，提供了二进制包，可以直接部署

#下载二进制包

[root@ubuntu2204 ~]#tar xf apache-dubbo-admin-0.5.0-bin-release.tar.gz -C /usr/local/
[root@ubuntu2204 ~]#ln -s /usr/local/apache-dubbo-admin-0.5.0-bin-release/ /usr/local/apache-dubbo-admin
[root@ubuntu2204 ~]#vim /usr/local/apache-dubbo-admin/bin/config/application.properties

admin.registry.address=zookeeper://zk1.wang.org:2181,zk2.wang.org:2181,zk3.wang.org:2181
admin.config-center=zookeeper://zk1.wang.org:2181,zk2.wang.org:2181,zk3.wang.org:2181
admin.metadata-report.address=zookeeper://zk1.wang.org:2181,zk2.wang.org:2181,zk3.wang.org:2181

实战案例：编译安装 Dubbo的 Web 管理 Dubbo Admin

官方说明

https://github.com/apache/dubbo-adminhttps://github.com/apache/dubbo-admin

注意:  内存建议4G以上,且编译时间可能会花10分钟以上的时间
注意: 本项目支持Ubuntu22.04和JDK8和JDK11以下版本
当前项目已经用golang重构，需要下载指定branch为develop,再用downlaod zip 形式下载JAVA的源代码

编译 dubbo admin

 #编译方法1:执行java编译
[root@ubuntu1804 dubbo-admin-develop]#mvn clean package 
 mvnw     NOTICE    README.md
 #编译方法2:执行java源码编译并跳过测试单元,推荐此方式

如果报错：

[ERROR] Killed
[ERROR] npm ERR! code ELIFECYCLE
[ERROR] npm ERR! errno 137
[ERROR] npm ERR! [dubbo-admin-ui@1.0.0](mailto:dubbo-admin-ui@1.0.0) build:`node build/build.js`

[ERROR] npm ERR!
[ERROR] npm ERR! Failed at the [dubbo-admin-ui@1.0.0](mailto:dubbo-admin-ui@1.0.0) build script.

解决办法：

服务器增加内存(推荐 4G 或以上)，避免被内核OOM
