Question

一般来说，我对apache和ssh都是陌生的，因此，即使这是我所缺少的愚蠢事物，我也将不胜感激。

我正在将网站迁移到新服务器，并正在设置httpd。我不得不将旧的httpd.conf更新为现在的2.4标准，但是现在当我运行systemctl start httpd时，它挂了3分钟以上，然后返回：

Job for httpd.service failed because a fatal signal was delivered to the control process. See "systemctl status httpd.service" and "journalctl -xe" for details.

status httpd.service返回

我不一定知道如何解析所有内容，也不知道有什么特别突出的地方。我还能做什么进一步调试？

Answer 1

我在Apache第三方模块上遇到了这个问题，这是很常见的，因为它们的配置不正确并导致服务失败。我会为您的模块创建一个备份，并单独测试每个模块的服务。

Answer 2

我在ProxMox 5.4上安装的Centos 7 VM上遇到了相同的问题，其中基础服务器断电了。相同的症状，没有明显的错误，只是非描述性超时。在停电之前，它工作正常。

我结束了对#LoadModule systemd_module modules/mod_systemd.so的注释，并启动了httpd。不知道为什么它起作用，但是它到底是什么。

这是现在的conf文件，以及有关谁的其他信息：

[root@zabbix httpd]# cat /etc/httpd/conf.modules.d/00-systemd.conf
# This file configures systemd module:
LoadModule systemd_module modules/mod_systemd.so

[root@zabbix httpd]# uname -a

无法在centos服务器上启动apache，未给出错误，只是超时
