Answer 1

如果您在安装 PHP 8.0后卸载了 PHP 7.x ，那么可能存在一些重叠，从而导致 PHP 8.0 安装失效。可能需要稍微重新安装。

尝试这个：

sudo apt install --reinstall php8.0 libapache2-mod-php8.0
sudo a2enconf php8.0-fpm
sudo service apache2 restart

这将重新加载 PHP 8.0，确保模块就位且完好无损，启用 FastCGI 进程管理器，然后重新启动 Apache。一般来说，当 PHP7.x 发生类似问题时，人们需要遵循这个过程。

后续...

有时，这AH01079: failed to make connection to backend: httpd-UDS是由需要重新启动的错误服务引起的。我不使用 PHP8.0，所以无法猜测服务的名称，但您可以列出系统上运行的所有服务，如下所示：

sudo service --status-all

这将为您提供一个服务列表，其中[-]表示其处于非活动状态，并[+]表示其正在运行。您将需要查找类似的服务php80-php-fpm并重新启动它：

sudo service php80-php-fpm restart

这可能会解决该问题。

如果与代理问题发生冲突...

有时，如果使用proxy_fcgi且发送缓冲区未填充一帧数据，可能会出现问题。可以通过编辑受影响站点的 Apache 配置来解决此问题：

<IfModule proxy_module>
    ProxyPassMatch ^(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1
</IfModule>

<IfModule mod_deflate.c>
    SetOutputFilter DEFLATE

    # Don't compress images
    SetEnvIfNoCase Request_URI \.(?:gif|jpeg|jpg|png)$ no-gzip dont-vary

    # Make sure proxies don't deliver the wrong content
    Header append Vary User-Agent env=!dont-vary
</IfModule>

希望这能解决最后的问题。
