RE: Without fastcgi - Daff - 05-25-2007 10:01 PM
ok, me again
I think its an Apache Problem but I don't know what to change.Here the difference.
Snippet of ps -aux from the VPS I'm struggling with:
root 27846 0.0 0.3 64400 3168 ? Ss 11:53 0:00 /usr/sbin/apache2 -k start
www-data 27848 0.0 0.2 64132 2360 ? S 11:53 0:00 /usr/sbin/apache2 -k start
www-data 27849 0.0 0.2 64132 2132 ? S 11:53 0:00 /usr/sbin/fcgi-pm -k start

www-data 27852 0.0 0.2 286768 3116 ? Sl 11:53 0:00 /usr/sbin/apache2 -k start
www-data 27854 0.0 0.2 286768 3120 ? Sl 11:53 0:00 /usr/sbin/apache2 -k start
vu2000 27890 0.0 0.1 53740 1900 ? S 11:53 0:00 /usr/bin/php4-cgi
vu2000 27891 0.0 0.1 53740 1900 ? S 11:53 0:00 /usr/bin/php4-cgi
That are 260 Megabyte RAM for an APACHE process (a simple script gives an Average of 149.0 MB per Apache process / thread)?!
Here the usage before starting the HTTPD (which still can be lowered by stopping Bind etc.):
188.496 MB
After starting:
634.727 MB
Thats a lot I'd say
On my current system:
www-data 32607 0.0 0.1 22868 10628 ? S 13:39 0:00 /usr/sbin/apache2 -k start -DSSL
www-data 32612 0.0 0.1 23148 10960 ? S 13:39 0:00 /usr/sbin/apache2 -k start -DSSL
www-data 32614 0.3 0.1 23032 11000 ? S 13:39 0:03 /usr/sbin/apache2 -k start -DSSL
www-data 32725 0.3 0.1 23180 10848 ? S 13:39 0:03 /usr/sbin/apache2 -k start -DSSL
Seems to be about 20 Megs. (the script displays an average of 7 MB per Apache Process / Thread). Very strange. 10 times as much RAM usage?
RE: Without fastcgi - BeNe - 05-25-2007 10:05 PM
Yeah - my Apache2 need 500MB RAM...
I will take a look at the config, this is too much.
Here is my current config:
Code:
# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_worker_module>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0

Jeay this is the same as my problem. I got also 512 burstable ram.
RE: Without fastcgi - Daff - 05-26-2007 12:52 AM
Hmpf... I'm searching for the problem hope somebody can help me. I'm a big fan of virtualization technology (actually I can build a multi server environment on a single hardware node... and if the resources don't suffice just move a VPS to another node and assign more). Its becoming more and more important and I think ISPCP has to run on such low resource machines (I don't want to assign a 1 Gig RAM machine just to host 5 or 10 small static web pages with ISPCP).
RE: Without fastcgi - Z4P - 05-26-2007 12:56 AM
I don't think it is ment that is uses so much ram. but it is really akward. 500 Mb is too much i got it too on a fresh install on my vps now.
RE: Without fastcgi - ephigenie - 05-26-2007 04:23 AM
perhaps you can try lowering the threads and forked processes for the mpm-worker ?
RE: Without fastcgi - Daff - 05-27-2007 04:54 AM
Please look here:
http://www.isp-control.net/forum/running-ispcp-on-a-low-resources-system-t-683.html
I've collected some memory decreasing stuff for VPS or other low resource systems.
RE: Without fastcgi - NetVista - 06-07-2007 04:01 AM
Had any one managed to run ispcp without fastcgi ? I have plenty of ram but i preffer not to use fastcgi at all. I will go ahead and suggest a release candidate without fastcgi
EDIT: BTW this is a fresh install with only 1 domain:

this is mine with 8 domain running without fastcgi and virtualization

RE: Without fastcgi - Z4P - 06-07-2007 04:05 PM
I suggest you follow that tutorial from Daff, it really lower your ram usage.
