Automatically Reboot Crashed Server?

[mthomas209]

Is there a way to automatically reboot a server if it crashes? I have a notification service that notifies me if things go down but then I have to manually reboot which is no good if it happens at 3am. Any suggestions on a script, program or service that will do a graceful reboot if my sites go down?

Nope, if the server has crashed then it isnt gonna manage to run a script.

Well in my case I can still access WHM so it has not totally gone down so I am guessing there is a way to do this. Are there not even any third party solutions for this?

If its only things like apache that have stoped working then cpsrvd should restart them

How do I enable this?

Try adding:

panic=15

To the kernel parameters in your boot loader. That will instruct the kernel to reboot 15 seconds after a kernel panic.

Dear abrender,

Would you be kind enough to let me know where I can modify the boot parameters of the kernel?

Warmest Regards!

PS: Do you mean modifying /etc/grub.conf ?

How to achieve this...

Here is a pretty good explanation on how to do this...

Short short version try:

echo 60 > /proc/sys/kernel/panic
echo "echo 60 > /proc/sys/kernel/panic" >> /etc/rc.d/rc.local

Enjoy!

Warmest Regards
