My CentOS will reboot every several days. There's nothing in

there any log I can look at? Or any suggestions to monitor the server

Odds are that it is hardware related (power supply, RAM, etc.) and crashing
before it can log anything.
    

+1      unless it is happening at the same time when a cron job is
running, as Scott mentioned.  Inspect the fans on the PSU and CPU and
make sure they are running.   Be sure it has good ventilation and is
clean inside.

Can you sent the hardware specs?  I use a lot of HP servers and they have a 'feature' called ASR that will reboot non-responsive servers.
