使用 OpenSUSE v15.2、Apache。
使用 zypper 安装 PHP-FPM。按照此网站上的说明进行操作： https://en.opensuse.org/SDB:Apache_FastCGI_and_PHP-FPM_configuration
我重启了 Apache 和 PHP-FPM。但是网站却无法在浏览器中加载。
我收到 HTTP 错误 502。
lynx http://10.20.30.40/info.php结果Alert!: HTTP/1.0 502 cannotconnect
还会出现这个错误：
McAfee Web Gateway - Notification
Cannot Connect
The proxy could not connect to the destination in time.

可能只是防火墙问题？
或者我的 Apache/PHP-FPM 配置有错误？

我尝试在本地使用 lynx 浏览器调试该问题，得到了以下结果：

也尝试过

执行 phpinfo()。php 并未执行，只是提供了 info.php 供下载。因此 php 未被解释。

php_admin_flag[log_errors] = on
但没有创建 /var/log/fpm-php.www.log。
