Why is my server keep on going down?!

[lpxxfaintxx]

Every single day, at around 4 PM EST, my server goes down. A few hours later, when I get back from class, I have to manually reboot the VPS from Virtuozzo. I think it may have something to do with the Apache, as I had a similar problem in my old Plesk server. Is there any way to find out why this is happening? Are there any way to prevent this? This is getting annoying... several hours of downtime in the middle of the day isn't very satisfying at all. =/

Also, for you SSH guru's, is there any way to reboot the server using SSH?

Server Down All Night

as vin quoted my previous post.. that will restart apache from SSH... the process outlined in that link is for CentOS/Fedora... if you are referring to rebooting the entire VPS VE itself using SSH, I am not sure.

Okay thanks, but is there any reason why it crashes? Can I take any precautions to prevent this?

[Daniel_DBS]

yes.. there are several reasons why this could be happening... could be a script issue, could be that you have way to much traffic for a VPS... could be a corrupt system file.. really could be several things... check your server error logs to see if there is anything that sticks out and if you cannot figure it out, submit a ticket to support

checkapache=`ps ax | grep -v grep | grep -c httpd`
if [ $checkapache -le 0 ]
then
/usr/local/apache/bin/apachectl startssl
fi

Name the file apachemonitor.sh and place it under the /etc directory

Set cron to run this:

*/1 * * * * sh /etc/monitor-apache.sh > /dev/null 2>&1

It will check apache every minute to ensure that it is running. I am using it on one of my boxes that has cPanel 11 and it keeps it going, but again, this is only a temporary fix.

Hrm, will this work with Plesk? Very clever, btw. Thanks a bunch.

[Daniel_DBS]

good question.. i believe with plesk the path to apache is different.. but i am FAR away from being plesk savvy as i really dislike it and havnt used it in several months

[ethix]

i dont use Plesk so i cant say, but if it dosnt work you would only have to change the path to Apache

that doesn't solve the problem!

if your apache is crashing, then something is wrong and instead of restarting apache you should find out whats wrong and fix that, then apache won't crash anymore and you won't need scripts like that.

btw, cPanel already does process monitoring and will restart apache and other services if they go down.
