Re: Re: Reg : Limiting http connections at Apache 2.4.25

[Luca Toscano <toscano.luca@xxxxxxxxx>]

Hi,

I think that you'd just need to install httpd without any reference to mod_qos (that is a third party module, so configure is not aware of it) and finally use apxs to compile/install the new module (more info in https://httpd.apache.org/docs/2.4/programs/apxs.html).

I'd also suggest to test it with httpd 2.4.25 rather than 2.2.27 :)

Hope that helps!

Hi Luca,

I am trying to use the mod_qos mod_qos-11.39. Is this applicable for Apache 2.4.25 reverse proxy in Red Hat Enterprise Linux 7.2. I followed the below command. however, mod_qos.so file is not getting created though I don't see any error with below commands. I am using non-root privileged account.

I tried compiling it using "apxs -i -c mod_qos.c -lcrypto -lpcre" , but could not succeed.

any help ?

tar xfz httpd-2.2.27.tar.gz
tar xfz mod_qos-11.39-src.tar.gz
ln -s httpd-2.2.27 httpd
cd httpd
mkdir modules/qos
cp ../mod_qos-11.39/apache2/* modules/qos
./buildconf
./configure --with-mpm=worker --enable-so --enable-qos=shared --enable-ssl --enable-unique-id
make

Not sure what is the status of mod_qos (third party module), but you might want to give it a try and see if it fits your needs!

Dear All,  

Any specific setup to cut and disallow the the further HTTP connections after specified limit (ex: 50 sessions?).

My requirement is to allow only 50 users and 51st user should get a custom error message to login after sometime. 

Regards, 

Vel

Thanks for response, 

Yes my requirement is to completely restrict/disalllow any further connections, example I want to allow only 50 sessions,  51st connection should get an error message to login later  after certain period of time. 

Regards, 

Vel

Indeed, but I don't think that's what the OP is looking for in an
apache proxy.  Rather the proxy reply with a "too busy" error page
than not take the connection at all, right?

The proxy balancer would be a place to look: that offers various
ways to determine how much traffic to send to a backend.  If that
doesn't meet your needs, there are several third-party traffic-
limiting modules.
