前后端分离项目，前后端共用一个域名。通过域名后的 url 前缀来区别前后端项目。

# demo.conf
server
    {
    listen 80;
    server_name demo.com; # 配置项目域名
    index index.html index.htm index.php;

    # 默认访问前端项目
    location / {
        # 前端打包后的静态目录
        alias /path/dist/;
        #解决页面刷新404问题
        try_files $uri $uri/ /index.html;
    }

    # 后端项目
    location ~* ^/(api|admin) {
    	try_files $uri $uri/ /index.php?$query_string;
    }

	# PHP-INFO-START  PHP引用配置，可以注释或修改，写法 1 和写法 2 任意一种都可以
    # 1.宝塔写法 include enable-php-80.conf;
    location ~ \.php(.*)$ 
    {
		root  /path/public/;
		try_files $uri =404;
		fastcgi_pass  unix:/tmp/php-cgi-80.sock;
		fastcgi_index index.php;
		include fastcgi.conf;
		include pathinfo.conf;
    }
	# 2.一般写法,使用 nginx 默认提供的配置，加上 `root` 相关配置即可
	location ~ \.php(.*)$ {
		root  /path/public/;
		fastcgi_pass   127.0.0.1:9000;
		fastcgi_index  index.php;
		fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
		fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
		fastcgi_param  PATH_INFO  $fastcgi_path_info;
		fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
		include        fastcgi_params;
	}
    #PHP-INFO-END

    # 前端静态资源处理

	# 后端静态资源处理
	location  ^~ /vendor/ {
