Answer 1

这个问题实际上并不是因为磁盘上缺少空间，而是因为缺少信号量。

有关详细信息，请参阅http://major.io/2007/08/24/apache-no-space-left-on-device-couldnt-create-accept-lock/。

非常感谢你的帮助

Answer 2

确保您没有在httpd.conf文件中输入任何错误条目

之后，重新启动服务。

服务httpd重新启动

Answer 3

当我从使用手动Apache2.4Start并重新启动到由systemctl启用时，我就遇到了这个问题。我从来没有空间问题，但结果是信号量。

键在行中：

Main PID: 18796 (code=killed, signal=KILL)

当我用

httpd -k start

一切都很好。但是，当我在systemctl中启用服务时，信号量就锁定了。

我按照下面的说明修正了这个问题：什么是信号量以及如何为Apache清除它们

另外，这里还有一个用于清除信号量的cron脚本：自动清除信号量的脚本
