13. monit example confiiguration: check process app-mongrel-5200 with pidfile /home/railsuser/demo/shared/tmp/mongrel.3000.pid start program = "/usr/bin/mongrel_rails cluster::start -C /home/railsuser/demo/current/config/mongrel/production.yml --clean --only 3000" as uid railsuser and gid railsuser stop program = "/usr/bin/mongrel_rails cluster::stop -C /home/railsuser/demo/current/config/mongrel/production.yml --clean --only 3000" as uid railsuser and gid railsuser if totalmem is greater than 100.0 MB for 2 cycles then restart if failed port 5200 protocol http # check for response with timeout 10 seconds then restart if cpu is greater than 80% for 3 cycles then restart if cpu is greater than 50% for 2 cycles then alert group app-mongrel

15. Execute this on the server(s) your deploying from: sudo gem install capistrano Other gem dependencies include: sudo gem install net-scp sudo gem install net-ssh sudo gem install net-ssh-gateway sudo gem install net-sftp Execute this at the root of your Rails stack: capify

16. Default commands are usually enough for the simplest Rails Applications Need a new script called script/spin Custom tasks need to be created for: monit, various deployment environments (test, staging, etc) cap deploy:setup cap deploy:check cap deploy:update cap deploy:start, stop, restart cap deploy
