nginx配置重点看server中的内容：

worker_processes  8;
pid /usr/local/nginx/logs/nginx.pid;events {# 此为 Linux 系统特为处理大批量文件描述符而作改进的 poll 事件模型use epoll;worker_connections  512; # 工作进程的最大连接数量# 允许同时接受多个网络连接multi_accept on;

vue前端项目配置

vue第一个项目配置：

# 发布路径
VITE_PUBLIC_PATH = /
#后台接口父地址(必填)
VITE_GLOB_API_URL=/back
#后台接口全路径地址(必填)
VITE_GLOB_DOMAIN_URL=/back

vue第二个项目配置

# 发布路径
VITE_PUBLIC_PATH = /second
#后台接口父地址(必填)
VITE_GLOB_API_URL=/back/second
#后台接口全路径地址(必填)
VITE_GLOB_DOMAIN_URL=/back/second

访问地址

第一个项目：http://domain:80/
第二个项目：http://domain:80/second
