Install Pound as Web Load Balancer

VPS Hosting

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 .


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:

1. Install RPMforge repository for yum. Go to and choose which CentOS operating system you used. In this case, I will use CentOS 5 64bit packages:

$ cd /usr/local/src
$ wget
$ rpm --import 
$ 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

        Port    80

        HeadRequire "Host: .**"

                Port    80
		TimeOut 300

                Port 80
		TimeOut 300

                Type Cookie
                ID   "JSESSIONID"
                TTL  300

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     *       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:     A

After DNS propagation is completed, you should notice that Pound has started to work and balancing your website
