Git-HuB-link of this practical
A load balancer is a device that acts as a reverse proxy and distributes network or application traffic across a number of servers. Load balancers are used to increase capacity (concurrent users) and reliability of applications. So load balancer is work as proxy so we can protect our server by Proxy .
In load balancer we use proxy ip and our request come from backend server ips so we can access web page from server without knowing actual ip.
In this blog you will you how to make load balancer .
Here i use three Machine one loadbalancer (127.0.0.1) two webserver
👉Now We Start make LoadBalancer by Ansible👈
👉 Create Inventory
In this practical Our control node will Loadbalncer so i use 127.0.0.1
Now make jinja code in haproxy.cfg file copy from /etc/haproxy/
Now Create the Ansible File for LoadBalncer and Webserver
Now run the playbook using the below command
Now See haproxy.cfg Config or not
So you can see in the above screenshot, the haproxy.cfg file is updated
Now Put ip of LoadBalncer (192.168.0.113) in chrome So you can access web page from server
So you can See our web page from .118 server ip .
