Server load high - VPS

[GoPantheoN]

The VPS is with 1GB ram and 4cpu with Kloxo. The website on it uses vBulletin.

The problem is that the load is high around 10 - 20. I think the problem is with apache. It is taking a lot of CPU Usage. The site is too slow.



I checked the processes using top cmd and result is


I also checked the dd I/O and speed was around 31 Mb/s.

Also this is the list of apache modules installed using httpd -l, is there anyother way to check it ?


Using apachectl -t -D DUMP_MODULES

Can anyone tell me is apache the cause for the slow speed of webpage loading and high CPU. Also what are the mods should I install for apache ?

Should I install mod_deflate and any other suggestions ?

Thank you.

Too much httpd, ddosed ?
Try restart the httpd and Check any connection that comes to your vps by netstat

[GoPantheoN]

Ya tried restarting httpd stillno use.

What parameter should i use with netstat to check if any ddos occurs ?

[koullis]

from kloxo switch from apache to lighttpd

[GoPantheoN]

Is that the only fix ? Can't Apache be fixed ?

kloxo is a hell of bloat. It seems to be worse than cPanel
Get a new VPS, read some tuts in how to use ssh and install WebMin

protip: MySQL is shit too. MariaDB

[GoPantheoN]

Php is also now taking much CPU :/ Any change to check if its a ddos ?

Restarting VPS.

In order to protect against DoS attacks (those involving one computer -> one server) I recommend mod_antiloris.

I have modified it sometime ago.

I only have windows builds but the source should build in linux as well. (although I don't know how)
