我最近在重启Apache时遇到了麻烦。我最近使用CentOS 7建立了一个Web服务器。我对我的php.ini文件进行了一些更改，并且相信我需要重新启动apache才能生效。当我尝试使用systemctl restart httpd.service或apachectl restart重启apache时，收到以下错误消息：
httpd.service的作业失败，因为控制进程退出并显示错误代码。有关详细信息，请参阅“systemctl status httpd.service”和“journalctl -xe”。
我输入journalctl -xe并收到：

我重新启动了我的服务器，现在apache似乎正常运行。

这很可能是httpd.conf文件中的配置错误
我在conf.d中创建了一个vhost.conf文件后遇到了同样的问题。删除这个新创建的文件（包含虚拟主机配置）后，我可以无错误地重启httpd。
