目标
- 建config-server
- 修改pom.xml
- 安装rabbitmq(先装windows版，后续部署改为linux版)
- mysql下建properties表
- 配置文件修改
配置中心默认支持的配置文件类型：git/svn jdbc filesystem redis等
我们选用的是数据库
建config-server
拷贝eureka-service 更名为config-server
修改后pom.xml如下

安装rabbitmq(先装windows版，后续部署改为linux版)
安装文件位置：
E:\工作文件\springcloud-new\rabbitmq
先安装：otp_win64_22.2.exe再安装rabbitmq-server-3.8.2.exe
1）otp_win64_22.2.exe只安装development即可，其余选项默认

2）安装rabbitmq-server 一路默认即可
双击C:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.2\sbin\rabbitmq-service.bat启动
进入C:\Program Files\RabbitMQ Server\rabbitmq_server-3.6.5\sbin下输入以下命令安装插件
rabbitmq-plugins.bat enable rabbitmq_management
服务启动命令：
rabbitmq-service.bat start
服务关闭命令：
rabbitmq-service.bat stop
访问http://localhost:15672/,默认用户名:guest,密码:guest进入控制台！
建用户和赋权限为可选，参考以下网址-略

输入正确的用户名密码，即可进入管理界面

mysql下建properties表

fetchRegistry: true
#此处为eureka-server服务地址，即指定向谁注册
serviceUrl:

启动类
一定注意@EnableConfigServer注解，之前因为没加这个注解，启动后其他服务无法找到他，调试了好长时间，踩过的坑啊
@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigServerApplication.class, args);
}
}
启动服务
注意一定先启动eureka-server再启动配置中心
目前可以只启动eureka-server和 config-server
简单看一下效果

bus服务算是搭建成功了，接下来需要连接BUS的那些服务需要做更改
哪些服务需要连接，取决于你的架构设计。
我来个简单的，先只有service1-n 连接
