一开始一切似乎都运行正常；运行sudo lampp start打印
Starting XAMPP for Linux 1.8.3-4...
XAMPP: Starting Apache...ok.
XAMPP: Starting MySQL...ok.
XAMPP: Starting ProFTPD...ok.
然而 apache 似乎立即停止了，因为在打印lampp status后立即运行：lampp start
Version: XAMPP for Linux 1.8.3-4
Apache is not running.
cat: /opt/lampp/var/mysql/hostname.pid: Permission denied
MySQL is running.
ProFTPD is running.
正在观看的/opt/lampp/logs/error_log节目：

据我所知，有很多可用磁盘空间，并且我有足够的可用内存。
是什么导致了此错误？
我读过一些关于 apache 不清除信号量数组的内容，但这似乎不是我的问题；ipcs -s返回：
