php – 如何在nginx中正确配置alias指令？

我一直在尝试在我的nginx网络服务器上配置多个webapp但我无法使用一个需要将$document_root设置为laravel公共文件夹的Laravel应用程序.
我目前正在尝试使用别名指令配置它,但由于一个不明确的原因,这不起作用.这是我想要做的.

# Default server configuration
#
server {
    listen 80;

    # SSL configuration
    #
    listen 443 ssl;

    error_log /var/log/nginx/error.log warn;

    ssl_certificate /etc/nginx/ssl/server.crt;
    ssl_certificate_key /etc/nginx/ssl/server.key;


    set $root_path '/var/www/html';
    root $root_path;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html index.php;

    server_name localhost;

    location /paperwork {
        alias /var/www/html/paperwork/frontend/public;
        try_files $uri $uri/;
        #location ~ .php {
        #   fastcgi_split_path_info ^(.+.php)(.*)$;
        #   fastcgi_pass unix:/var/run/php5-fpm.sock;
        #   include /etc/nginx/fastcgi_params;
        #   #fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
        #   #fastcgi_intercept_errors on;
        #}
    }

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

    location / {

    }


    location /wallabag {
        try_files $uri $uri/ /index.php;
    }

    location /laverna {
        try_files $uri/ /index.php;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ .php${
        # With php5-cgi alone:
        #fastcgi_pass 127.0.0.1:9000;
        # With php5-fpm:
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        #try_files $uri $uri/ =404;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }



    # deny access to .htaccess files,if Apache's document root
    # concurs with nginx's one

    location ~ /.ht {
        deny all;
    }
}

为了测试我的“别名”配置,我在/var/www/html/paperwork/frontend/public/test.php中放了一个’test.php’文件,并试图通过https://IP/paperwork/test.php访问它.我得到一个404错误,nginx没有任何内容错误日志.
如果我在浏览器中尝试https://IP/paperwork/frontend/public/test.php,它会显示test.php文件而不会出现错误.
如果我在php位置取消注释try_files行,则没有任何改变.

如果我将test.php复制到/var/www/html/paperwork/test2.php并访问https://IP/paperwork/test2.php,则文件显示没有错误,所以我在这里看到别名不起作用,因为文书工作中没有test2.php目录.

如果我在文书工作位置取消注释php位置,我可以有不同的行为.有了这个,像https://IP/paperwork/test.php这样的请求不会显示404而是显示空白屏幕.

我已经经历了很多与此相关的论坛/问题,但我无法获得一个简单的任务,如显示test.php …

谢谢 ！
