当我想让我的 apache2 使用 https 时，我使用这个命令：
sudo a2enmod ssl
并且我想重新启动 apache2 我使用：
sudo 服务 apache2 重启
但是我得到了这个错误：
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl
-xe" for details.
我用
systemctl 状态 apache2.service
我有：
apache2.service - The Apache HTTP Server

而/etc/apache2/apache2.conf第146行是：
IncludeOptional mods-enabled/*.load
/etc/apache2/mods-enabled/ssl.load第2行内容为：
LoadModule ssl_module /usr/lib/apache2/modules/mod_ssl.so
我不明白发生了什么，有人可以帮助我吗？
