I'm setting up a production server on Ubuntu 10.04 using this technology stack: Nodejs Nginx to serve static contents Mongo Redis Upstart for running applications as services Monit for monitoring node application and nginx server The server will host only 5 applications of this type. Nothing else. How would you setup Ubuntu Users? It's a good idea to create a User per Application? Would you install software (node, mongo...) as root or as user(s)? Thanks in advance
