使用Debian 10安装Apache + php7测试的最简单方法:

apt-get update -y
apt-get install apache2 php7.0 libapache2-mod-php  -y
sudo service apache2 restart

如果我们在同一页做下面

Sudo apt-get install PHP Sudo apt-get install php-{bcmath,bz2,intl,gd,mbstring,mysql,zip,fpm} -y

要在Apache2中启用PHP 7.2 FPM，请执行以下操作:

A2enmod proxy_fcgi SetenVIF

a2enconf php7.2-fpm

更新2:Apache下载。php文件而不是渲染

在那之后，我遇到了上面的问题。还有类似的问题。

我不知道为什么，但它只发生在我的。php文件在/var/www/html/根文件夹。对于子目录来说一切正常。(例如wordpress和phpmyadmin工作得很好)

这就是我的解。我决定启用php模块。所以我运行了这个命令:

a2enmod php7.2

但我得到了这个错误:

考虑php7.2依赖mpm_prefork: 考虑mpm_prefork的冲突mpm_event: 错误:mpm_event模块已启用-由于冲突无法继续。它首先需要被禁用! 考虑mpm_prefork的冲突mpm_worker: 无法为php7.2启用依赖mpm_prefork，终止

所以我决定通过运行以下命令禁用mpm:

sudo a2dismod mpm_prefork
sudo a2dismod mpm_worker
sudo a2dismod mpm_event

然后重启apache:

Systemctl restart apache2

然后启用php7.2(我安装的版本):

Sudo a2enmod php7.2

现在一切都很好。

我有一个案例，我不小心开始解压我的文件目录在根。它从我的文件文件夹中添加了。htaccess文件，这将阻止所有php

# If we know how to do it safely, disable the PHP engine entirely.
<IfModule mod_php5.c>
  php_flag engine off
</IfModule>

底线检查根目录下的.htaccess文件。

听起来你的配置好像有问题，下面是一些你可以检查的东西:

Make sure that PHP is installed and running correctly. This may sound silly, but you never know. An easy way to check is to run php -v from a command line and see if returns version information or any errors. Make sure that the PHP module is listed and uncommented inside of your Apache's httpd.conf This should be something like LoadModule php5_module "c:/php/php5apache2_2.dll" in the file. Search for LoadModule php, and make sure that there is no comment (;) in front of it. Make sure that Apache's httpd.conf file has the PHP MIME type in it. This should be something like AddType application/x-httpd-php .php. This tells Apache to run .php files as PHP. Search for AddType, and then make sure there is an entry for PHP, and that it is uncommented. Make sure your file has the .php extension on it, or whichever extension specified in the MIME definition in point #3, otherwise it will not be executed as PHP. Make sure you are not using short tags in the PHP file (<?), these are not enabled on all servers by default and their use is discouraged. Use <?php instead (or enable short tags in your php.ini with short_open_tag=On if you have code that relies on them). Make sure you are accessing your file over your webserver using an URL like http://localhost/file.php not via local file access file://localhost/www/file.php

最后，查看PHP手册以获得更多的设置技巧。

此问题的另一个可能原因可能是您试图在UserDir模块的“用户目录”中运行脚本。在用户目录下运行PHP脚本默认是禁用的。如果脚本位于主文件夹的public_html目录中，并且您试图从http://localhost/~your_username访问它，那么就会遇到这个问题。

要解决这个问题，打开/etc/apache2/mods-enabled/php7.2.conf。必须注释或删除底部的标记块

<IfModule mod_userdir.c>
    <Directory /home/*/public_html>
        php_admin_flag engine Off
    </Directory>
</IfModule>

确保脚本包含

<?php

在应该执行的代码之前。<?之间不能有空格这里是PHP。
