[users@httpd] How to distribute Web Access?

I have a web application, i.g. a WAR file. I will deploy this war on several
web-servers. They have the URL. How can I configure the web-server, assumed
I use Apache Tomcat, sothat the web access can be distribute to these web
servers? For example I have 10 web-servers, the daily access is 100000. I
want these accesses to be devided to 10 web servers.

How can I do that? Can I just make configuration or do I need hardware such
as dispatcheer?

[users@httpd] httpd(s) are consuming all cpu's

Posted by tjzsm1 <tj...@yahoo.com>.
Hi everybody,
&nbsp;
We are running apache 1.3.39, modssl-2.8.30 and openssl-0.97m on Red Hat linux AS 3 and weblogic 8.1.6 on Solaris. The problem I got is there are always a few httpd processes keep running and taking all cpus. I can kill them but they will come back after one or two hours. Restarting apache can not solve the problem too. When I do a lsof on any httpd child process it returned lots of 'CLOSE_WAIT' even on those cpu consuming and non-cpu-consuming processes. 
&nbsp;
I checked Internet and basically understand what was happening for those CLOSE_WAITs, but how could we solve the problem?
&nbsp;
Thanks,
Cary

If you are looking for an all Apache solution, 2.2 has mod_proxy_balancer.

http://httpd.apache.org/docs/2.2/mod/mod_proxy_balancer.html

Although in production my results are mediocre at best. Squid as a reverse
proxy is the better option. No idea if it is supported under Win2k3.

Not a good idea.

You could have one apache httpd serve as a loadbalancer for a farm of
tomcat backen servers. Consult the mod_jk documentation on how to do
this.

This sounds good.

But I use Windows 2003 Server.

Besides, can one use the Apache Http Server to do this?

http://www.linuxvirtualserver.org is probably worth a look. I have been

Look at mod_jk module from apache ? But in your case I think you need either
hardware load balancer or use existing web server with mod_jk

Is the so-called 3rd party device&nbsp;a hardware?

You need a load balancer or some other 3rd party device. There could be 
a way to do it in Apache, but I haven't seen it.
