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。

更新nginx config /etc/nginx/sites-available/default或你的配置文件

如果你正在使用php7，使用这个

    location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;      
    }

如果你正在使用php5，请使用这个

    location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/run/php/php5-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;
    }

详情请访问这里

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

然后进入浏览器，享受…

在我的情况下，我没有使用/etc/nginx/sites-available/default，我使用了一个不同的服务器块配置文件(例如example.com)，我能够解决这个问题的唯一方法是删除默认的服务器块配置文件符号链接:

$ rm /etc/nginx/sites-enabled/default

然后重新加载Nginx:

$ sudo systemctl reload nginx

我在这个问题上挣扎了很长时间，这些步骤对我很有效。

步骤1:所有PHP文件的位置块配置

location ~ \.php$ {
        try_files $uri /index.php =404;
        fastcgi_pass unix:/run/php/php7.3-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
}

步骤2:在配置文件中添加fastcgi_param 我们只需要打开/etc/nginx/fastcgi_params文件，并在文件末尾添加以下一行。

fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;

然后重新启动服务，

systemctl restart php7.3-fpm
systemctl restart nginx

试试这个:

Edit /etc/nginx/sites-available/default Uncomment both listen lines to make Nginx listen on port 80 IPv4 and IPv6. listen 80; ## listen for ipv4; this line is default and implied listen [::]:80 default_server ipv6only=on; ## listen for ipv6 Leave server_name alone # Make site accessible (...) server_name localhost; Add index.php to the index line root /usr/share/nginx/www; index index.php index.html index.htm; Uncomment location ~ \.php$ {} # pass the PHP scripts to FastCGI server listening on (...) # location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+?\.php)(/.+)?$; # 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; } Edit /etc/php5/fpm/php.ini and make sure cgi.fix_pathinfo is set to 0 Restart Nginx and php5-fpm sudo service nginx restart && sudo service php5-fpm restart

我一周前才开始使用Linux，所以我真的希望能帮助到你。我正在使用一个纳米文本编辑器来编辑文件。如果没有，运行apt-get install nano。谷歌想知道更多。
