Simple Load Balancer

This is a very simple load balancer with Vagrant + NGINX + Tornado + MySQL + REDIS

How to use

1. Clone this repository into some folder
2. Open console, go to this folder and type vagrant up

What will vagrant up do?

After you write vagrant up you will have 5 virtual machines: #####- Name: vm_master | IP: 192.168.50.5 The Master VM, who is going to do the load balance This vm will do:

• Update apt cache
• Install and Configure NGINX

#####- Name: vm_1 | IP: 192.168.50.10 This vms will do:

• Update apt cache
• Install and Configure NGINX
• Install PIP and the project dependences
• Install VirtualEnv and create a new VirtualEnv called venv into /vagrant
• Install and Configure Supervisor

#####- Name: vm_2 | IP: 192.168.50.20 This vms will do:

• Update apt cache
• Install and Configure NGINX
• Install PIP and the project dependences
• Install VirtualEnv and create a new VirtualEnv called venv into /vagrant
  • Install and Configure Supervisor

#####- Name: vm_3 | IP: 192.168.50.30 This vms will do:

• Update apt cache
• Install and Configure NGINX
• Install PIP and the project dependences
• Install VirtualEnv and create a new VirtualEnv called venv into /vagrant
• Install and Configure Supervisor

#####- Name: vm_mysql | IP: 192.168.50.100 This vm will do:

• Update apt cache
• Install PIP
• Install MySQL
  • Create the database: app_db
  • Create the user: remoto with password: 123
  • Grant all permissions to user remoto to the database app_db

#####- Name: vm_redis | IP: 192.168.50.200 This vm will do:

• Update apt cache
• Install REDIS

Load Balancer

The machine responsible for the load balancer is serving on ip 192.168.50.5. After the vagrant up you can access to http://192.168.50.5 and see the magic ;)

MySQL

The MySQL machine is serving on ip 192.168.50.100 with one database called app_db, user remoto and password 123.

REDIS

The REDIS machine is serving on ip 192.168.50.200 in default port: 6379

To-do's

1. Create another vm for REDIS
2. Install supervisor in vms
3. Configure supervisor in all vms
4. Develop the API
5. Develop the application
