AH00558：httpd：创建VirtualHost后无法可靠地确定服务器的标准服务器名称错误

Question

我已经在CentOS 8中安装了Apache服务器，并且可以正确地服务于http和https页面，也就是说，当从浏览器连接到服务器时，我可以查看Apache测试页面。>

我使用本教程启用https：https://www.techrepublic.com/article/how-to-enable-https-on-apache-centos/

非常有效。但是，当我尝试使服务器能够提供除默认测试页以外的其他网页时，尝试使用]重新启动apache服务器时，出现错误“ AH00558：httpd：创建VirtualHost后无法可靠地确定服务器的标准服务器名称错误” >

sudo systemctl restart httpd  
这是我的/etc/https/conf/http.conf的内容，其中删除了一些注释。

我感觉这与ServerName条目有关。如上所示，默认情况下已对其进行注释，但是我尝试取消注释并与VirtualHost文件中的coonfiguration匹配，但出现了相同的错误。 
这是/etc/httpd/sites-available/adorkable.conf的内容

（NOTE

：adorkable一词已被beem替换为我的用户名username1）

在发出systemctl重新启动httpd之后输出systemctl状态httpd：

如何在此处重新启动httpd服务？

我已经在CentOS 8中安装了Apache服务器，并且它可以正确地服务于http和https页面，也就是说，当从使用的浏览器连接到服务器时，我可以查看Apache测试页面。 [
