XFileSharing Pro - How to configure Apache ?

[200299]

Hi
How best to set up apache to 500 users online?

You advise someone? I still have a message
*500 time out*

You can not upload and download

Code: Select all

    StartServers          3
    MinSpareServers       2
    MaxSpareServers      10
    ServerLimit         550
    MaxClients          550
    MaxRequestsPerChild   4000

try
Timeout 700
KeepAlive off
MaxKeepAliveRequests 150
KeepAliveTimeout 5
StartServers 20
MinSpareServers 5
MaxSpareServers 15
MaxClients 256
MaxRequestsPerChild 500

its not good

still connecting and download error

What is your server?

[200299]

I have one main server and two file servers

HP ProLiant DL120

Debian 6 32bit
16GB RAM
4 HDD x 1,5 TB SATA3, 7200rpm, 6Gb/s, 64MB cache
connection 2Gbit/s

one moment connection 600-800 users/one file server

traffic daily 5TB - 10 TB from one server

where did you buy you servers "?

where did you buy you servers "?

how this relates to setting?

not related. Just a question. maybe im interested to buy one from there

by the way do you have direct links enabled ?

[PowerChaos]

well
i can not 100% say how to configure your server but those settings will do fine for 12GB ram ( I7 920 )

Code: Select all

Timeout 30
TraceEnable Extended
ServerSignature Off
ServerTokens ProductOnly
FileETag All
StartServers 5
<IfModule prefork.c>
MinSpareServers 5
MaxSpareServers 10
</IfModule>
ServerLimit 512
MaxClients 512
MaxRequestsPerChild 10000
KeepAlive On
KeepAliveTimeout 5
MaxKeepAliveRequests 100

then you can add this code to in httpd.conf

Code: Select all

ExpiresActive On
ExpiresDefault A0
Header  set Cache-Control "private, no-cache, no-store, proxy-revalidate, no-transform"
Header  set Pragma "no-cache"

but code 500 is not a time out code ..
500 is server error

time out is 504 (no server response)

http://en.wikipedia.org/wiki/List_of_HTTP_status_codes

then a smalls sidenote to your server

are you realy using 32 BIT ??
because 32 bit is limited to 4GB MAX
so what a waste of ram ..

I guess you use the prefork module (apachectl -l shows what you use)
Try to see if there's any bottlenecks or akward usage via the top command
if with maxclients 550 there are no visible bottlenecks, try upgrading that limit
also just put the spareservers to 50 or so...
600 downloaders with apache could probably work, but I recommend getting NGINX since I know it works pretty well with many downloaders.

@pwrchaos, it's 4 gb per process... (though I don't know how well system i/o cache is). I agree with using a 64 bit OS for your next fileserver though.

keep alive on causes overload for me all the time,
also the serverlimit seems to small, i would raise it to 1024 or so.

hello,
i have new fileserver:

Intel Core i5-2400
4x3.1+ GHz

8 GB DDR3
8TB
100mb/s bandwidth

and my apache2 configuration:

Code: Select all

KeepAlive Off
MaxKeepAliveRequests 100
KeepAliveTimeout 5
Timeout 800
<IfModule mpm_prefork_module>
    ServerLimit		     1024
    StartServers               5
    MinSpareServers        15
    MaxSpareServers       50
    MaxClients                 1024
    MaxRequestsPerChild  0
</IfModule>
AcceptFilter http none 
EnableSendfile Off 
EnableMMAP off 
TraceEnable On 
ServerSignature Off 
ServerTokens ProductOnly 
FileETag None 

I have 200 uploads, 6000 downloads and 3TB traffic a day.
Sometimes my server is overloaded, what can I do for better performance?

thanks best regards

[PowerChaos]

you got 8TB traffic and you use 3TB per day ??
then you can just survive 2 days and your traffic is up

i can offer you a better server then with no traffic limit ( 100mbit dedicated port or 1GB port )

anyway

Code: Select all

KeepAlive Off 
MaxKeepAliveRequests 100 
KeepAliveTimeout 5 
Timeout 15
<IfModule mpm_prefork_module> 
    ServerLimit           512
    StartServers               5 
    MinSpareServers        5 
    MaxSpareServers       10 
    MaxClients                 350
    MaxRequestsPerChild  1000 
</IfModule> 
AcceptFilter http none 
EnableSendfile Off 
EnableMMAP off 
TraceEnable off 
ServerSignature Off 
ServerTokens ProductOnly 
FileETag None

use maxrequestperchild instead putting it on 0 (so childs get generated and terminated to prevent mem hog)
with keepalive off ( or on a low value) your server makes a lot more requests but that eliminate the use of a higher max clients (as connections only stay open for a second )

for the rest it is hard to configure on feeling , you need to try and tweak as needed to get the optimum value

hello,
no I mean 8TB disk

traffic is 100mb/s and unlimited



what do you mean with mem hog? and timeout only 15? I think for fileserver is better to put keepalive off.

[coolsalman_1]

hello power.

I am looking for dedicated server 100mb unlimited or 1Gb port with nice specs.
