好吧，我找到了一个解决方案，可以非常容易地在nginx服务器的子目录中配置和安装Laravel，在/etc/nginx/sites-available/yourSite配置文件中，添加以下内容：

location ^~ /laravel {
    alias /var/www/laravel/public;
    try_files $uri $uri/ @laravel;

    location ~ \.php {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        include /etc/nginx/fastcgi_params;
    }
}

location @laravel {
    rewrite /laravel/(.*)$ /laravel/index.php?/$1 last;
}

瞧，你的路线将正常工作，他们应该如何。

在我花了几个小时在这个问题上之后，最后我用一个子域地址解决了我的问题，如下所示：
如果你想把你的laravel项目放到一个ngnix-ubuntu 16-php.7.2服务器上的subfolder中，那么下面是ngnix配置：
1.你的嵌套（子文件夹）不在你的主文件夹内
/var/网址/主目录：/var/www/嵌套：
则您的配置应为：

location /nested {

        alias /var/www/nested/public;

        try_files $uri $uri/ @nested;

               location ~ \.php$ {
                        include fastcgi_params;
                        fastcgi_param SCRIPT_FILENAME $request_filename;
                        fastcgi_pass   unix:/run/php/php7.2-fpm.sock;

                                }
   }

location @nested {
        rewrite /nested/(.*)$ /nested/index.php?/$1 last;
}

1.主文件夹中的laravel-test文件夹（子文件夹）：
/var/网址/主目录：/var/www/主目录/嵌套目录：
则您的配置应为：

location /laravel-test {

    alias /var/www/main/laravel-test/public;

    try_files $uri $uri/ @laravelTest;

           location ~ \.php$ {
                    include fastcgi_params;
                    fastcgi_param SCRIPT_FILENAME $request_filename;
                    fastcgi_pass   unix:/run/php/php7.2-fpm.sock;

                            }

  }

location @laravelTest {
        rewrite /laravel-test/(.*)$ /laravel-test/index.php?/$1 last;
}

这是解决我的别名问题的变通方法，Nginx不像使用root指令那样查找/var/www/portal/public/portal/foo中的文件

location /portal {
 alias /var/www/html/portal/public; #preferred over root

 # @portal is a named location
 try_files $uri $uri/ @portal;

 location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $request_filename;
 }
}

location @portal {
rewrite /portal/(.*)$ /portal/index.php last; # Remove ?/$1 since fastcgi_params adds query string
}

出于某种原因，别名导致了这个问题，并且不起作用。因此，也许这会帮助其他人，所以下面是我为使这个问题起作用所做的工作。正如你所看到的，我去掉了“别名”，并将laravel/public添加到等式中。

location ^~ /laravel/public {
            index home.php home.html home.htm index.html index.htm index.php;
            try_files $uri $uri/ @laravel;

            add_header X-Frame-Options "SAMEORIGIN";
            add_header X-XSS-Protection "1; mode=block";
            add_header X-Content-Type-Options "nosniff";
            charset utf-8;

            location ~ \.php {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/run/php/php7.2-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
                fastcgi_buffers 16 16k;
                fastcgi_buffer_size 32k;
                include fastcgi_params;
            }
        }
        location = /favicon.ico { access_log off; log_not_found off; }
        location = /robots.txt  { access_log off; log_not_found off; }

    location @laravel {
       rewrite /laravel/public/(.*)$ /laravel/public/index.php?/$1 last;
    }

它对我不起作用，所以我得到了另一个解决方案。
1.我创建了一个“普通”的laravel域，指向http://generic.laravel根目录/my/laravel/path/public
1.之后，我在真实的域上创建了一个位置来代理我的通用Laravel：

location /laravel {
    rewrite /laravel/?(.*)$ /$1 break;
    proxy_pass http://generic.laravel;

}
1.不幸的是，Laravel将使用url http://generic.laravel来创建链接。您可以按照以下步骤Laravel: Change base URL?来解决它

我遇到过几个类似错误403或404的情况，我认为这个方法是有效的.不要忘记根据你在服务器上的php版本（php8.1-fpm.sock）来修改php版本.注意your_domain www.your_domain是基于你的网站.

server {
    listen 80;
    listen [::]:80;
    root /var/www/html;
    index index.html index.htm index.php;
    server_name your_domain www.your_domain;
    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location /yourlaravelproject {
        alias /var/www/html/yourlaravelproject/public;
        try_files $uri $uri/ /index.php$args;

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_pass unix:/run/php/php8.1-fpm.sock;
        }
    }
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php8.1-fpm.sock;
    }
    location ~ /\.ht {
        deny all;
    }
}

配置后，不要忘记添加这个到你的符号链接，然后systemctl restart nginx。我敢肯定，为Laravel 8和9仍然工作，因为我最近刚刚测试的子文件夹中的Laravel 9项目和工程罚款。

在server指令的root参数中指定公共文件夹
在文件/etc/nginx/sites-available/am2.aminversiones.com中

server {
    ...
    root /home/forge/am2.aminversiones.com/public;
    ...
}

重新启动nginx服务：sudo systemctl restart nginx

地点/文具{别名/var/www/html/文具/公共场所;尝试文件$uri $uri/@信纸;位置~. php ${包含代码段/fastcgi-php. conf;文件名：/run/php/php7.2-fpm. sock;快速cgi参数脚本文件名$请求文件名;}}
位置@信纸{重写/信纸/（. *）$/信纸/index.php？/最后;}
