hi,

I'm fairly new to dedicated server,

i want to know what its the better way to test the stability of a server/ putting very high load on it to make sure all is ok ?

There is some software i can use or a good way step by step on redhat ?

Step for testing a server will be realy appreciated, it seem there is no info on the forum about that ...

Thanks very mutch for your help !

After an experience with bad ram, we started stress-testing out all our boxes after setup but before use... one thing we liked doing was repeated kernel compiles... a script like

#!/bin/sh
#set -x
t=1
while [ -f log.$t ]
do
t=`expr $t + 1`
done

while true
do
make clean
make -k bzImage > log.$t
t=`expr $t + 1`
done
We'll start it and let it run for a few hours (or two days in one case, we forgot about it)... come back, cancel the script, and check the results of the log.* files.. they should all be identicle (except the last one, because you aborted the script mid compile)

It's worked well for us.. but if someone's got a better way to stress out a system, I'm all for hearing it. ;)

put a cron job to compile all the sources over and over and see if the hardware stays put after 48 hours..

this genius of an idea is hosticle's.. i am just a fool

Thanks for this info great help, i'm realy new whit that
and want to make sure i'm not doing wrong !

btw another thing...

I see in form (when you check to buy a server)
they need a domaine name for setup,

those i need a domaine for each server or there
is another way, can i use a sub-domaine from
a current domain hosted at another place, if yes how this can be setuped ?

if you have like 5 server can you use like

server1 # server1.domaine.com
server1 # server2.domaine.com
server1 # server3.domaine.com
server1 # server4.domaine.com

is this possible or i realy need a new domain for each server ?

thanks a lot for your help !

There is a script called memtest.sh on freshmeat.net that seems to be good. I just set the settings real high (40-50), and run it for a day or so.

As for domain name, most hosts don't really take note of that. The most they will do is to pre-setup your dedicated server with it as the hostname, so its really not a problem.

Then about domain name there is a way to point a sub domain from a current domain hosted somewhere other than the server ?
like if i want to put a blank page on the server or a stat page then want to put it whit http://server1.mydomaine.com but mydomaine.com is hosted on another server ?

Thanks very mutch this help me a lot !

yes, each name can be on a different server/IP. All you have to do is to create the A record for it, you may have domain.com hosted on one server by creating an A record and pointing it to one IP, and then create another A record for sub.domain.com to point to another IP.

You just need to figure out how to do this with your name server.

[admin@wofut lucifer-1.0]$ uptime
12:12pm up 7 days, 20:21, 1 user, load average: 1.23, 0.80, 0.39
[admin@wofut lucifer-1.0]$


i'll leave this running for a few days ;)

btw... seti@home would be a good test too as it keeps your load @ 1.00 or just over

just curious, who's fault would it be if your stress testing breaks the server? :D

Who pays for replacement?

It would be your host, because servers aren't supposed to break under high load.

Another good program is cpuburn - Try it!
