使用 OpenSUSE v15.2、Apache。
使用 zypper 安装 PHP-FPM。按照该网站上的说明进行操作： https://en.opensuse.org/SDB:Apache_FastCGI_and_PHP-FPM_configuration
我重新启动了 Apache 和 PHP-FPM。但是该网站未在浏览器中加载。
我收到 HTTP 错误 502。
lynx http://10.20.30.40/info.php结果Alert!: HTTP/1.0 502 cannotconnect
还得到这个错误：
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 配置中有错误？

我尝试在本地使用 lynx 浏览器调试问题并得到以下结果：

也尝试过
lynx http://127.0.0.1/info.php
Looking up 127.0.0.1 first
Looking up 127.0.0.1
Making HTTP connection to 127.0.0.1

HTTP/1.1 200 OK
它执行 phpinfo()。 php 没有执行，只是提供了 info.php 供下载。所以php不被解释。

显示它正在运行，并显示重新启动，仅此而已。

在 www.conf 中我启用了

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