Linux kernel Panic后自动重启机器的设置

http://blog.csdn.net/blaider/article/details/8562045

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
设置kernel系统参数:
vi /etc/sysctl.conf
#增加此行,以保证此设置持续有效;
#含义是当系统遇到kernel panic时,系统在30秒后reboot;
kernel.panic = 30

#修改此参数,,以保证下一次当系统遇到kernel panic后有效;
#以后无需再修改,默认从上面的设置中加载;
vi /proc/sys/kernel/panic
echo 30 > panic


另外Redhat提供的可导致kernel panic的方式;
执行这几行代码,你的linux系统就crash了；
cd /proc/sys/kernel
echo 1 > sysrq   (记录log等级为1)
cd /proc
echo c > sysrq-trigger
