Nginx虚拟主机无法正常工作（错误的重定向）

我是nginx的新手，我的虚拟主机有问题 . 当我尝试访问vhost时，虚拟主机无法正常工作，它将被重定向到localhost“欢迎使用nginx” . 以下是我配置的内容：

/etc/hosts config：

127.0.0.1 localhost localhost.localdomain

::1 localhost localhost.localdomain

我想从新的根目录访问另一个站点，在www目录下 /usr/share/nginx/html/www 有一个 wordpress .

/etc/nginx/sites-available/testingweb config：

server {
        listen 80 default_server;
        # listen [::]:80 default_server ipv6only=on;

        root /usr/share/nginx/html/www;
        index index.php index.html index.htm;


        # Make site accessible from http://localhost/
        server_name testingweb.com;

#       rewrite ^ https://$http_host$request_uri? permanent;
        return 301 https://$host$request_uri;

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


   error_page 404 /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
            root /usr/share/nginx/html;
    }

        location ~ \.php$ {
                try_files $uri =404;

        #       # With php5-fpm:
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }

#       location = /favicon.ico {
#               alias /usr/share/nginx/html/favicon.ico;
#       }


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

根据配置，我的配置有什么问题？我无法通过域 testingweb.com 访问 /usr/share/nginx/html/www 目录上的wordpress文件？它总是重定向到 default 主机而不是 testingweb 主机？

对不起，我的英语不好..
