首先，你必须在浏览器中删除缓存

打开terminal，执行如下命令:

sudo apt-get install php-gettext
sudo nano /etc/nginx/sites-available/default

然后在默认文件中添加如下代码:

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

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

    server_name localhost;

    location / {
        try_files $uri $uri/ =404;
    }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

如果有任何不匹配，只需纠正并从终端通过以下命令重新启动Nginx

须藤系统缓冲nginx系统

然后进入浏览器，享受…

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

    root /var/www/html;
    index index.php index.html index.htm;

    location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    }
}

上面的代码片段在php7.2的情况下对我有用

上面的答案似乎超出了我的解决方案。这是我的文件:

/etc/nginx/sites-available/default

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;
}

希望这能帮助那些在周日下午感到沮丧的人(c:

我看到了上面的很多解决方案，其中许多对我来说是正确的，但我不明白他们在做什么，担心只是复制粘贴代码，特别是fastcgi。这是我的2美分，

nginx is a web server (and not an application server) and thus, it can only serve static pages. whenever, we try rendering/returning a .php file, for example index.php, nginx doesn't know what to do, since it just can't understand a .php file (or for that matter any extension apart from a select few like .html, .js etc. which are static files) Thus in order to run other kinds of files we need something that sits between nginx and the application (here the php application). This is where common gateway interface (CGI) comes in. It's a piece of software that manages this communication. CGIs can be implemented in any possible language Python (uWSGI), PHP (FPM) and even C. FastCGI is basically an upgraded version of CGI which is much much faster than CGI.

对于某些服务器，如Apache，有内置的支持来解释PHP，因此不需要CGI。

这个数字海洋链接，很好地解释了安装FPM的步骤，我没有写解决php文件下载而不是渲染问题所需的步骤，因为其他答案IMHO很好。

检查你的nginx配置文件扩展名为*.conf。 例如:/etc/nginx/conf.d/myfoo.conf

我也遇到了同样的情况。在我将我的配置文件从myfoo重命名为myfoo.conf后，它修复了。 不要忘记在重命名nginx后重新启动它。

我要去精神试图解决这个问题，对我来说，问题是Cloudflare已经缓存了php文件，并一直让我下载它。

对我来说，解决办法是清除Cloudflare上的缓存。
