CakePhp&；Nginx子页面未显示

我最近在8085端口的nginx上托管了cakefp应用程序。

我重新启动nginx，索引页面加载正常。但每当我点击同一个网站（另一个页面）的某个链接时，网页上什么都没有打印出来。

请告诉我我的nginx设置有什么问题。

这是我的nginx配置文件。

server { 
    server_name  example.com;
    root   /var/www/html/cakephp/app/webroot;
    access_log  /var/log/nginx/cakeapp.access.log;
    error_log   /var/log/nginx/cakeapp.error.log;
    listen       8085;
    rewrite_log on;
    # rewrite rules for cakephp
    location / {
        index  index.php index.html;
        # If the file exists as a static file serve it 
        # directly without running all
        # the other rewite tests on it
        if (-f $request_filename) { 
            break; 
        }
        if (!-f $request_filename) {
            rewrite ^/(.+)$ /index.php?url=$1 last;
            break;
        }
    }
