所以我正在尝试设置虚拟主机。

我已经制作了灯泡服务器，并尝试安装多个wordpress网页。 当我创建虚拟主机文件时，问题就开始了。启用它后，Apache不想重新加载。

它给出了这个错误。

Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.

命令systemctl status apache2.service显示

journalctl -xe命令显示了

这是我的虚拟主机文件

<VirtualHost *:80>
    ServerAdmin admin@example1.com
    ServerName example1.com
    ServerAlias www.example1.com
    DocumentRoot /var/www/html/example1.com/public_html
    ErrorLog $var/log/apache2/error.log
    CustomLog $var/log/apache2/access.log combined
</VirtualHost>

如何解决这个问题？
