私はもう2日間頭を叩いています。問題は、index.php処理されずにダウンロードされることです。私が使用していますUbuntu 14.04、Nginx、php5。nginx/site-available/default下記の通りです。index.php多くの投稿で規定されているようにエントリを追加しました。
    server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;
    root /usr/share/nginx/html;
    index index.php index.html index.htm;
    # Make site accessible from http://localhost/
    server_name localhost;
    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
    }
    # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
    #location /RequestDenied {
    #   proxy_pass http://127.0.0.1:8080;    
    #}
    #error_page 404 /404.html;
    # redirect server error pages to the static page /50x.html
    #
    #error_page 500 502 503 504 /50x.html;
    #location = /50x.html {
    #   root /usr/share/nginx/html;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #   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;
    #}
}
    #server {
    #   listen 8000;
    #   listen somename:8080;

    #}

    #   location / {

    #}
nginx.conf以下のように..です

    }

解決策は今まで続いた。
- のエントリを追加しました index.php
- default_type application/octet-stream;nginx.conf の行を削除しました
- ファイル内のfastcgiエントリのコメントを外しましたdefault。
私も同じ問題でこれらの解決策を試しましたが、私にはうまくいきませんでした。
- /programming/16747980/nginx-and-php-fpm-is-downloading-index-php-instead-of-processing-it
- 他のWebサイトの多くと並んで、スタックオーバーフローのようなリンクがもう1つあります。
