【问题描述】：

正在按照此处的 youtube 教程安装 Wordpress 和 LEMP 堆栈：https://www.youtube.com/watch?v=4beEybPzYqQ。

除了运行systemctl restart php7.2-fpm nginx返回错误外，每一步都没有错误：

Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

所以，我做了systemctl status nginx.service，它返回

还有journalctl -xe:

在我看来一切都很好？我检查了系统日志，但在运行 systemctl status php7.2-fpm.service 时它没有显示任何内容。

/var/log/nginx/error.log 由于某种原因也完全为空。

我应该从哪里开始寻找造成这种情况的原因？非常感谢任何帮助。

嗯。我只是删除了所有 mysql-server、php、nginx 相关文件，包括依赖项，重新启动...不知何故它现在可以正常工作了。
