Pound Reverse Proxy
Pound is http reverse proxy services which passes all client browser requests to one or more back-end http server. Pound also can be use as load balancer to distribute the load of multiple client requests among several servers.
Below is the mini HOWTO Pound with noguix linux and already been tested with my current environment without problem.

Note: You can have pound running together with apache on the same server but pound must be running on port 80 while apache on another port let say port 8080
My EnvironmentNo comments
Yesterday me & my colleague (KC) been assigned by my Boss another ad-hoc task for Toyota Malaysia production server which is currently running file server using SLES9 + OES2. My job is very simple, do full back-up for the server and he suggested we using Acronis as a back-up tool and to be honest, I never use it before. Since it’s ad-hoc task & I have to finished it within a short period before Novell NTS coming & do OES2 patching on the server, I decided to go with noguix live-cd to be as a destination back-up server.
As per our early plan we should start the the first back-up at 8:00PM unfortunately, everything went wrong from the beginning. SATA Bios, authentication failure, bad media problem delayed us from the first back-up until 11:30PM. At one time I was thinking “could be this another disaster to us”. FYI, two weeks before my junior mistakenly deleted customer /opt (oracle directory) during disaster recovery which cost our company name & reputation. But as professional, I calmed myself, I told KC I went for a dinner (A&W) alone while KC try to solve the problem. He try with Knoppix, SLES10, Netfilter to setup the dhcp, samba, nfs & ftp server as it’s needed by Acronis but failed. While I’m having dinner, my brain still working for the solution. After half an hour, I’m back calmly with my grateful magic hand to safe our name’s.No comments
After long delay and difficulty I had, I finally managed to consolidate all servers & services within VMware ESX 3.5 running on top of my AMD Athlon64 X2 machine plus noguix linux acting as VMFS Datastore via NFS to keep all virtual machine images inside Celeron 1.7Ghz machine (old server).
Previously, within one physical server & one virtual machine it’s really hit the performance of my server. Everything must to be running inside this two which is too much for the server. But with ESX now, I manage to have total 7x virtual machines which running different services on different servers and different OS. I can separate Squid from Apache machine, Sendmail running on his standalone primary server while scalix waiting to get into this environment too. Same goes to DNS & DHCP services.
So, everything now running happily on my new virtual environment.No comments
