spacenear-nosql

Quick hack to make the spacenear.us tracker run without SQL DB using a flat JSON file. Easy to deploy to Amazon EC2 and also allows load balancing using multiple instances by synching positions.json between them unidirectionally.

Deploying to Amazon EC2

1. Start an Ubuntu 12.x instance
2. Login by doing ssh ubuntu@instance-ip -i instance.pem
3. Set hostname in /etc/hostname and add it to /etc/hosts
4. sudo apt-get update && sudo apt-get upgrade
5. Restart instance
6. sudo apt-get install nginx php5 php5-fpm
7. Put tracker into /srv/tracker
8. Create folder /var/data for the JSON files
9. Put nginx-site.conf to /etc/nginx/sites-available/default
10. Set "cgi.fix_pathinfo = 0;" in /etc/php5/fpm/php.ini
11. sudo service php5-fpm restart
12. sudo service nginx start

Adding another instance

1. Follow the steps above to setup a new EC2 server
2. Add server pem to main instance and add it to ~/.ssh/config
3. Modify and run /srv/tracker/utils/mirror.sh on the main instance
4. Make sure that habitat is uploading only to the main instance
5. Add both instances to Amazon Elastic Load Ballancer
