Simulate a Distributed System with Tornado, Supervisor, Nginx, Docker

Soothe

Tools

• Tornado as server
• Supervisor as process manager
• Nginx as reverse proxy and load balancer
• Docker as container platform

Instruction

• install tornado

pip install tornado

• install supervisor

pip install supervisor

• run supervisord

supervisord -c supervisor/init.conf

• run supervisorctl or open http://localhost:9001 in your browser to manage processes.

Best practice: don't use inet_http_server in production unless you provide security for it.

• set nginx settings for load balancing

vi /etc/nginx/conf.d/default.conf

upstream backend {
    server localhost:8000 weight=2;
    server localhost:8001 weight=1;
    server localhost:8002 weight=1;
    server localhost:8003 backup;
}
server {
    listen           127.0.0.1:80;
    location / {
        proxy_pass http://backend;
    }
}

• test nginx configs

nginx -t

• reload nginx configs

nginx -s reload

• open browser and go to localhost
