🌟 Configuration of Load balancer & webserver using Ansible Automation 🌟
Manual way or using Ad hoc command Configuration of Load balancer & webserver using Ansible Automation in given link: (https://github.com/Pratikshinde55/Load-Balancer.git)
❄️ By using Ansible Automation (playbook):
For this Configuration i take four instances, Amazon linux EC2 instances.
one for Ansible-Master node : 54.197.11.139
two instances for webserver (Backend): Public IP backend 1- 54.159.221.239,Backend 2- 44.202.88.227
one for Load Balancer (Frontend):lb: 18.206.228.124
In ansible master node i created 2 playbooks one for Loadbalancer and one for webserver & one jinja template file and one webpage.
⚡Step-1:
In master node 1st i created webpage (index.php): This webpage index.php is deploy to webserver which can client access from browser:
#cat > index.php
⚡Step-2:
Create Inventory , In inventory i made two groups "Web" group for webserver nodes & "lb" group for LoadBalancer node:
#vim /etc/ansible/hosts
we can check ansible list of hosts using following command:
⚡Step-3:
Now Create Webserver (Backend) playbook and here hosts for webserver playbook is "web" group, in web group two instances are kept:
In this playbook 1st Task install Httpd package , 2nd Task is Install php package which is because my webpage in the for of '.php' , 3rd is Deploy web page index.php to destination "/var/www/html/" & 4th Task for start httpd service:
#vim webserver.yml
⚡Step-4:
Run Webserver.yml playbook - this playbook do configuration in web group where Two nodes .
#ansible-playbook webserver.yml
⚡Step-5:
Now for Load Balancer need registration of backend nodes for this , i created jinja file "pratik.cfg.j2" which pass registration information to LoadBalancer playbook "lb":
#vim pratik.cfg.j2
Note:
here we use Round Robin Algorithm that work as client will connect to web server through Load balancer , 1st connect to web 1 then web 2 and next web 3 then again go to 1. here also bind the port no. as 8080 .
⚡Step-6:
Create Load balancer Playbook "lb.yml", add lb group where only one instance for lb IP:-18.206.228.124
In this playbook 1st task for install haproxy package It is loadBalancer that i used,
2nd task for rigistration of backend webservre to Load balncer for this pratik.cfg.j2 jinja template used , In haproxy Load balancer configuration file for load balancer is kept in "/etc/haproxy/haproxy.cfg"
3rd task for Start haproxy service
#vim lb.yml
Note:
HAproxy is one of the product of load balancer, HAproxy is a high-performance, open source load balancer & reverse proxy for HTTP and TCP .
⚡Step-7:
Run Load balancer "lb.yml" playbook , This do load balncer configuration on lb group:
#ansible-playbook lb.yml
💥Configuration of Load balancer & webserver done successfully:
Check on Google or Browser Publich IP load balancer : port no. that bind:
Note:
Load balancer node Inbound rules ->> All trafic , Anywhere ( remove Firewall )
