Pound, which is a reverse proxy, load balancer, auto HTTP fail-over and HTTPS front-end for Web server.
The installation and implementation is very simple with help of RPMforge. Pound is open-source software which you can find out more information about it at http://www.apsis.ch/pound/ .
we already have the website hosted in both servers, which already copied using cPanel copy account tools.
Variable as below:
OS: CentOS 5.6 64bit
Website URL: http://download.myinstaller.org/
1. Install RPMforge repository for yum. Go to http://wiki.centos.org/AdditionalResources/Repositories/RPMForge and choose which CentOS operating system you used. In this case, I will use CentOS 5 64bit packages:
$ cd /usr/local/src $ wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm $ rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt $ rpm -Uhv rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm |
2. Install Pound via yum:
$ yum install pound -y |
3. Rename original config file because we will use our configuration file:
$ mv /etc/pound.cfg /etc/pound.cfg.ori $ touch /etc/pound.cfg |
4. Copy and paste following configuration into /etc/pound.cfg using text editor:
User "nobody"
Group "nobody"
LogLevel 1
Alive 2
ListenHTTP
Address 109.169.80.202
Port 80
End

BackEnd

TimeOut 300
End

End

5. Make sure Pound is working at startup service and started:
$ chkconfig pound on $ service pound start |
6. Check whether Pound is listening to the correct value:
$ netstat -tulpn | grep pound tcp 0 0 109.169.80.202:80 0.0.0.0:* LISTEN 29358/pound |
7. To check the log files, you can monitor /var/log/messages using following command:
$ tail -f /var/log/messages |
8. Last step is to point the subdomain to the load balancer IP. In this case, I need to login to my domain name server and change the A record for this subdomain. Example as below:
download.myinstaller.org A 109.169.80.202 |
After DNS propagation is completed, you should notice that Pound has started to work and balancing your website
