PHP 代码无法在 Web 浏览器上正确呈现

我刚刚根据以下教程安装了带有 PHP-FPM 的 Apache

如何在 Ubuntu 20.04 上使用 PHP-FPM 设置 Apache

wolf@linux:~$ dpkg -l apache2 libapache2-mod-fcgid software-properties-common php7.4 php7.4-fpm

wolf@linux:~$

phpinfo()使用函数测试 PHP

wolf@linux:/var/www/html$ cat info.php 
<?php phpinfo(); ?>
wolf@linux:/var/www/html$

目前唯一的问题是 PHP 文件似乎在 CLI 中可以正确处理，但不能通过 Web 浏览器正确处理。

wolf@linux:/var/www/html$ php info.php | head
phpinfo()
PHP Version => 7.4.12

System => Linux 4.15.0-122-generic #124-Ubuntu SMP Thu Oct 15 13:03:05 UTC 2020 x86_64
Build Date => Oct 31 2020 17:04:09

Loaded Configuration File => /etc/php/7.4/cli/php.ini
Scan this dir for additional .ini files => /etc/php/7.4/cli/conf.d
wolf@linux:/var/www/html$

不幸的是，它无法在网络浏览器上运行

在此处输入图片描述

php7.4-fpm 服务已启动

wolf@linux:~$ systemctl status php7.4-fpm

这是 access.log 上唯一出现的内容

wolf@linux:~$ tail -F /var/log/apache2/access.log

127.0.0.1 - - [02/Nov/2020:07:23:50 ] "GET /info.php HTTP/1.1" 304 180 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36"

没有新的日志在/var/log/apache2/error.log和/var/log/apache2/other_vhosts_access.log

在这种情况下出现了什么问题以及我应该怎么做才能解决它？

Apache 还需要配置支持 PHP-FPM（apache2 + php-fpm）

/etc/apache2/conf-available/php7.4-fpm.conf安装 PHP-FPM 后会自动创建Apache 配置文件。

如果不存在，您也可以手动创建此文件。

/etc/apache2/conf-available/php7.4-fpm.conf

# Redirect to local php-fpm if mod_php is not available
<IfModule !mod_php7.c>
<IfModule proxy_fcgi_module>
    # Enable http authorization headers
    <IfModule setenvif_module>
    SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=$1
    </IfModule>

    <FilesMatch ".+\.ph(ar|p|tml)$">
        SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost" # PHP version (php -v command)
    </FilesMatch>
    <FilesMatch ".+\.phps$">
        # Deny access to raw php sources by default
        # To re-enable it's recommended to enable access to the files
        # only in specific virtual host or directory
        Require all denied
    </FilesMatch>
    # Deny access to files without filename (e.g. '.php')
    <FilesMatch "^\.ph(ar|p|ps|tml)$">
        Require all denied
    </FilesMatch>
</IfModule>
</IfModule>

然后，激活该proxy_fcgi模块：

sudo a2enmod proxy_fcgi

另外，激活配置文件：

sudo a2enconf php7.4-fpm

就您显示的内容而言，处理程序尚未执行。因此，它将 PHP 文件显示为文本文件。

您是否创建了虚拟主机条目？

我检查了您链接的文档，发现缺少了一些内容。

他们在下面创建了网站的配置： /etc/apache2/sites-available/000-default.conf

但应在以下位置创建此文件的符号链接：/etc/apache2/sites-enabled/

请执行以下操作：

ls -al /etc/apache2/sites-available/
ls -al /etc/apache2/sites-enabled/
cat /etc/apache2/sites-available/000-default.conf
