我知道存在类似的问题：httpd.service 作业失败
但它与我的不一样。我尝试使用以下方法重新启动 Apache
sudo apachectl restart
我收到以下错误：
httpd.service 作业失败。请参阅“systemctl status httpd.service”和“journalctl -xn”了解详情。
以下是来自的日志systemctl status httpd.service：

答案1
您提供的信息systemctl status httpd.service看上去很有趣也很有用，但是我们无法读懂，因为它已被省略了。
9 月 27 日 18:57:57 localhost.localdomain httpd[5357]: AH00526: l 上的语法错误... 9 月 27 日 18:57:57 localhost.localdomain httpd[5357]: 此处不允许
幸运的是，输出还告诉你该怎么做
提示：有些线条被省略了，使用 -l 可以完整显示。
所以这里要做的事情是运行
systemctl status -l httpd
这将用缺失的信息填补空白。
你应该读这些信息，考虑它告诉你什么并采取适当的行动。

谢谢大家的帮助。我刚刚解决了这个问题。当我尝试编辑配置文件时，出现了问题/etc/httpd/conf.d/phpMyAdmin.conf
我在第 18 行添加了一行，因此我必须删除该行才能使 httpd 再次工作。:)
干杯！！
