Load Balancer Solution with Apache

This project was continuation of project 7, implementing a distributed solution to the architecture by introducing a load balancer as seen in the diagram below.

1. An EC2 machine was launched with linux ubuntu running in AWS console

2. Apache2 installed on the machine

   • sudo apt update
   • sudo apt install apache2 -y
   • sudo apt-get install libxml2-dev

   #Enabling modules:

   • sudo a2enmod rewrite
   • sudo a2enmod proxy
   • sudo a2enmod proxy_balancer
   • sudo a2enmod proxy_http
   • sudo a2enmod headers
   • sudo a2enmod lbmethod_bytraffic

   #Restarting apache2 service

   • sudo systemctl restart apache2 #Ensuring Apache2 is running
   • sudo systemctl status apache2

3. Configuring Load Balancer and Registering Webservers to its configuration files

   • sudo vi /etc/apache2/sites-available/000-default.conf

   • #Adding the info to the configuration file

<Proxy "balancer://mycluster"> BalancerMember http://:80 loadfactor=5 timeout=1 BalancerMember http://:80 loadfactor=5 timeout=1 ProxySet lbmethod=bytraffic # ProxySet lbmethod=byrequests

    ProxyPreserveHost On
    ProxyPass / balancer://mycluster/
    ProxyPassReverse / balancer://mycluster/

#Restart apache server

- sudo systemctl restart apache2

4. Getting the public DNS address of Load-balancer

5. Site successfully loading from load balancer with registered webservers
