我正在 ubuntu 上编辑 apache 模块，当我尝试使用重新启动服务器时，service apache2 restart我收到以下消息：
Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.
运行命令systemctl status apache2.service

我的 apache2.conf 不是 140 行，因为它是基于我的所有模块的 conf 文件生成的。
请问我该如何进一步调查？
