nginx 位置不响应路径名

Question

我已经设置了站点文件，但不知何故别名不起作用。该站点是一个内部站点，所有媒体文件都保存在服务器外的 NAS 上。我尝试使用 /video/ 和 /pictures/ 而不是完整路径来访问它们。但是无论我怎么尝试，它们都无法加载。有人能帮忙吗？

server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

    #root /usr/share/nginx/www;
    root /var/www/Misc/public_html;
    index index.php index.html index.htm;

    # Make site accessible from http://localhost/
    server_name Misc;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ /index.php;
            # Uncomment to enable naxsi on this location
            # include /etc/nginx/naxsi.rules
    }

    location /video/ {
            alias /media/Misc/Misc/All\ Videos/;
    }
    location /pictures/ {
            alias /media/Misc/iVideo/Library\ Caches/Misc/All\ Videos/;
    }

    # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests

    #location = /50x.html {
    #       root /usr/share/nginx/www;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
    #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
    #       # With php5-cgi alone:
    #       fastcgi_pass 127.0.0.1:9000;
    #       # With php5-fpm:
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #       deny all;
    #}
}
