nginx下TP3.2访问页面总是404

这是我测试onethink用的配置 可以参考一下

server {
    listen ;
    server_name onethink.dev www.onethink.dev;

    root /vagrant/www/onethink;
    index index.php;

    location / {
        if ( -f $request_filename) {
            break;
        }

        if ( !-e $request_filename) {
            rewrite ^/(.*)$ /index.php/$ last;
            break;
        }
    }    

    location ~ \.php {
        set $script $uri;
        set $path_info "";
        if ($uri ~ "^(.+\.php)(/.+)") {
            set $script $;
            set $path_info $;
        }    

        include fastcgi_params;
        fastcgi_index index.php;
        fastcgi_pass 127.0.0.1:;
        fastcgi_param PATH_INFO $path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$script;
        fastcgi_param SCRIPT_NAME $script;
        try_files $uri =;
    }
}
