Task Requirements :
There is a static website running in the Datacenter. They have already configured the app servers and the code is already deployed there. To make it work properly, they need to configure the LBR server. There are several options for that, but the team has decided to go with HAproxy. FYI, apache is running on port 8083 on all app servers. Complete this task as per the below details.
Install and configure HAproxy on the LBR server using yum only and make sure all app servers are added to the HAproxy load balancer. HAproxy must serve on the default HTTP port (Note: Please do not remove stats socket /var/lib/haproxy/stats entry from haproxy default config.).
Once done, you can access the website using the StaticApp button on the top bar
Execution :
Navigate into the LBR server using the ssh command.
ssh username@server-ip-addr
Step 1 - Install HAproxy
sudo yum install haproxy -y
Step 2 - Configure HAproxy
sudo vi /etc/haproxy/haproxy.cfg
Add the following configuration. Make sure to replace app_server_ip1, app_server_ip2, etc., with the actual IP addresses of your application servers.

Step 3 - Check HAProxy Configuration
haproxy -c -f /etc/haproxy/haproxy.cfgStep 4 - Restart, Check Status and enable HAProxy to start on boot
sudo systemctl restart haproxysudo systemctl status haproxysudo systemctl enable haproxy
