无法在CentOS 7上重新启动apache

Question

我最近在重新启动Apache时遇到了麻烦。 我最近使用CentOS 7设置了Web服务器。我对php.ini文件进行了一些更改，并认为我需要重新启动apache才能生效。 当我尝试使用systemctl restart httpd.service或apachectl restart重新启动apache时，出现以下错误消息：

由于控制进程退出并显示错误代码，因此httpd.service的作业失败。 有关详细信息，请参见“ systemctl状态httpd.service”和“ journalctl -xe”。

我输入journalctl -xe并收到：

Answer 1

我重新启动服务器，现在apache似乎可以正常运行。

Answer 2

这很可能是您的httpd.conf文件中的配置错误

在conf.d中创建vhost.conf文件后，我遇到了同样的问题。 在删除了这个新创建的文件（包含虚拟主机配置）之后，我可以重新启动httpd而不会出现错误。
