引导类AdminApplication中加上注解@EnableDiscoveryClient可以让该服务注册到nacos注册中心上去

启动nacos，启动admin微服务,可以查看到admin服务已经在服务列表中了

把application.yml.bak中的部分内容复制到Nacos中

搭建admin前端工程

通过nginx的反向代理功能访问后台的网关资源
通过nginx的静态服务器功能访问前端静态页面

配置nginx

①：解压资料文件夹中的压缩包nginx-1.18.0.zip

②：解压资料文件夹中的前端项目admin-web.zip

③：配置nginx.conf文件

在nginx安装的conf目录下新建一个文件夹vhost,在当vhost文件夹中新建heima-leadnews-admin.conf文件

heima-leadnews-admin.conf配置如下：

listen 8803 -- 监听 8803端口，前端工程的端口
upstream 配置负载均衡
location ~/service_admin/(.*) 匹配路径中包含service_6001的请求
proxy_pass 反向代理到 http://heima-admin-gateway ，这是我们配置的负载均衡，前端先把请求发给nginx，由nginx把请求转发给网关 localhost:6001
upstream heima-admin-gateway{
server localhost:6001;
}

server {
   listen 8803;
   location / {
       root D:/workspace/admin-web/;
       index index.html;
   }

   location ~/service_admin/(.*) {
       proxy_pass http://heima-admin-gateway/$1;
       proxy_set_header HOST $host; # 不改变源请求头的值
       proxy_pass_request_body on; #开启获取请求体
       proxy_pass_request_headers on; #开启获取请求头
       proxy_set_header X-Real-IP $remote_addr; # 记录真实发出请求的客户端IP
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #记录代理信息
   }
}
打开nginx.conf 引入heima-leadnews-admin.conf文件加载
# 引入自定义配置文件
include vhost/*.conf;

启动nginx

在nginx安装包下中使用命令提示符打开，输入命令 start nginx.exe 。启动项目

重启nginx：nginx -s reload

关闭nginx nginx -s stop

打开前端项目进行测试 -- > http://localhost:8803
