Nginx 将我的请求传递给默认或本地地址

Question

NGINX 配置有两个问题。
我尝试设置prestashop在CentOS 7和Nginx根据本仪器我在 Prestashop 论坛上发现类似的东西。nginx.config 文件如下：

    user nginx;
    worker_processes auto;
    error_log /var/log/nginx/error.log;
    pid /run/nginx.pid;
    events {
        worker_connections 1024;
}
http {
  client_header_timeout 300;
  client_body_timeout 300;
  fastcgi_read_timeout 300;
  client_max_body_size 32m;
  fastcgi_buffers 8 128k;
  fastcgi_buffer_size 128k;
  map $http_upgrade $connection_upgrade {
      default upgrade;
      ''      close;
    }
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   6500;
    types_hash_max_size 3048;
    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    include /etc/nginx/conf.d/*.conf;
    include nginx-prestashop.conf;
}

并且 nginx-prestashop.conf 文件是：

upstream php-fpm {
    server 127.0.0.1:9000; #unix:/run/php-fpm/www.sock;
}
server {
    listen 0.0.0.0:80;

    server_name_in_redirect off;
    error_log /var/log/nginx/error.log;

当我尝试的时候http://www.example.com它将我重定向到本地主机/index.php？当我尝试https://www.example.com/它带我进入 NGINX 默认页面，该页面位于/usr/共享/nginx/html/当我尝试洞察服务器时，我遇到了连接被拒绝消息。
我删除了默认配置。
我找不到原因。
