【Dubbo03】消息队列与微服务之dubbo-admin 二进制与编译安装

实战案例：二进制安装 dubbo-admin

新版用Golang重构，提供了二进制包，可以直接摆设

1. #下载二进制包
2. [root@ubuntu2204 ~]#wget https://github.com/apache/dubbo-admin/releases/download/0.5.0/apache-dubbo-admin-0.5.0-bin-release.tar.gz
3. [root@ubuntu2204 ~]#tar xf apache-dubbo-admin-0.5.0-bin-release.tar.gz -C /usr/local/
4. [root@ubuntu2204 ~]#ln -s /usr/local/apache-dubbo-admin-0.5.0-bin-release/ /usr/local/apache-dubbo-admin
5. [root@ubuntu2204 ~]#vim /usr/local/apache-dubbo-admin/bin/config/application.properties
7. admin.registry.address=zookeeper://zk1.wang.org:2181,zk2.wang.org:2181,zk3.wang.org:2181
8. admin.config-center=zookeeper://zk1.wang.org:2181,zk2.wang.org:2181,zk3.wang.org:2181
9. admin.metadata-report.address=zookeeper://zk1.wang.org:2181,zk2.wang.org:2181,zk3.wang.org:2181
11. [root@nacos ~]#/usr/local/apache-dubbo-admin/bin/startup.sh
12. dubbo-admin is starting，you can check the /usr/local/apache-dubbo-admin/logs/catlog.out
13. #观察日志
14. [root@nacos ~]#tail -f /usr/local/apache-dubbo-admin/logs/catlog.out

实战案例：编译安装 Dubbo的 Web 管理 Dubbo Admin

官方阐明
https://github.com/apache/dubbo-admin

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

留意:  内存发起4G以上,且编译时间大概会花10分钟以上的时间
留意: 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，须要下载指定branch为develop,再用downlaod zip 情势下载JAVA的源代码

假如报错：

1. [ERROR] Killed
2. [ERROR] npm ERR! code ELIFECYCLE
3. [ERROR] npm ERR! errno 137
4. [ERROR] npm ERR! [[email protected]](mailto:[email protected]) build:`node build/build.js`
5. [ERROR] npm ERR! Exit status 137
6. [ERROR] npm ERR!
7. [ERROR] npm ERR! Failed at the [[email protected]](mailto:[email protected]) build script.

办理办法：
   服务器增长内存(保举 4G 或以上)，制止被内核OOM 
  启动服务

1. #确保zookeeper已启动
2. [root@node1 ~]#zkServer.sh status
3. /usr/bin/java
4. ZooKeeper JMX enabled by default
5. Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
6. Client port found: 2181. Client address: localhost. Client SSL: false.
7. Mode: follower
9. #启动dubbo admin方法1
10. [root@ubuntu1804 ~]#cd /usr/local/src/dubbo-admin-develop;mvn --projects dubbo-admin-server spring-boot:run
11. #启动dubbo admin方法2
12. #指定用8888端口,默认8080
13. [root@ubuntu1804 ~]#java -jar /usr/local/src/dubbo-admin-develop/dubbo-admin-distribution/target/dubbo-admin-0.3.0-SNAPSHOT.jar--server.port=8888
