Squid load balancing configuration

maxy · 10-07-2011, 07:51 AM

Hi Friends,

I have RHEL5 server, and we want to configure SQUID proxy server as load balancer.

Ex.

[ RHEL5 server1 ] [ RHEL5 server2 ]
Squid squid

We want to configure round Robbin squid, like..
to load balance server , one request goes to server 1
other request goes to server 2, and again same.

Please suggest how this can be done..?or if there are open source tools for this.Please let me know how i should proceed.

The best open source tool you could use is Google...lots of how-tos can be found, by putting in "linux squid load balancer". Here's a few with examples, some can even be found by looking at the Squid documentation.

It's left to know if it's a forward or reverse proxy, but anyway I think this applies to both. IMO you can achieve this with an iptables-based "nth" loadbalancing scheme (greatly documented all over the web), and furthermore you can use some peer config in the squids to take advantage of already cached objects across them.
