Apache MaxClients

[yoachan]

Dear all,

I wanted to increase my Apache's MaxClient.
In Service Configuration >> Apache Configuration >> Global Configuration said that "This interface allows up to the default of 256.". From what I read, I need to increase Apache's ServerLimit.
Because I can't find it at Global Configuration, I opened my httpd.conf using ssh, and added

ServerLimit 512

and change

MaxClients 512

than restart my Apache service.

My question is:
1. Will this works?
2. When I look at WHM Apache Global Configuration, I still see 256 as my MaxClients instead of 512 as I expected. Why is that so?
3. We have a quad core processor and 8GB RAM, and currently the machine is just sitting there with no heavy processes. Any idea how much MaxClients that my machine can afford? Because all this time the one that peak out is our MaxClients.

Any ideas appreciated.

Regards,

YoChan

Thanks for your reply

ServerLimit works if you set it from WHM.
But not works if you set it from config files.

You can set it from Apache Configuration -> Include Editor

Write your configuration to Pre Main Include field.
This works

I've add

ServerLimit 512

in Pre Main Include section for Apache 2.2.16 which I use. But still when I want to edit Apache Global Configuration, I still see this note:

This interface allows up to the default of 256.

and when I change the MaxClients to 512, I get this red warning:

Value (512) is over the limit (256), using previously saved value (if any) or default (150)

and my maxclients was reset back to 256...

Did I missed anything?

In your WHM > Service Configuration > Apache Configuration > Global Configuration you'll find some settings you may be interested in.
(That thread linked above here is out of date)

Yes, there are some settings, but still no answer for my question.......

Yes, there are some settings, but still no answer for my question.......

For Apache 2:

Modify /usr/local/apache/conf/includes/pre_virtualhost_global.conf
and add these lines:

ServerLimit 2048
MaxClients 2048

and then restart Apache.

This is to set it to 2048, ofcourse you can modify it to whatever you want.
For Apache 1.3 just modify httpd.conf's MaxClients setting.

[whr]

Try the below syntax in httpd.conf file:

<IfModule prefork.c>
ServerLimit 512
MaxClients 512
</IfModule>

Save and quit httpd.conf

Then run the Apache distiller

/usr/local/cpanel/bin/apache_conf_distiller --update
