linux - (apache2.service 的作业失败，因为控制进程退出并出现错误代码)在尝试激活 webdav 模块后发生

Question

我试图启动我的 apache 网络服务器，但我不能。每次我输入:sservice apache2 start我得到错误:Job for apache2.service failed because the control process exited with error code.我在尝试为 apache2 激活 WebDAV 模块后第一次遇到错误。但我已经停用了它。我也重新启动了服务器，但没有效果。
我在我的第二台电脑上运行 apache 并通过 SSH 访问它。
这是我的日志文件:

您可以使用它来检查是否有东西正在使用该端口。

netstat -plant | grep 80
