Today I Learned

TIL, 2017-11-26, Setting up a Server.

  • git rev-parse --abbrev-ref HEAD if you want to see the current branch in Git.
  • Capistrano pty: telling the back-end that this is an interactive session. Non-login, non-interactive shell.
  • Nano exiting: Ctrl-X. Saving: Ctrl-O.
  • Setting up RDS: You can do free tier here.
  • source /home/deploy/.rvm/scripts/rvm to add rvm to rvm install on the server.
  • Even if you are going to use RDS, you still need to install PG on the EC2 instance.
  • Install node if no JS runtime (uglifier will tell you this).
  • You make the RDS allow public but set its security group to only allow stuff in the same VPC.
  • nc -zv 8299 to check if you can connect to the RDS.
  • Security group has the highest chance to like make the thing not work re connecting to the database. What I did was to set the security group to allow PostgreSQL for the VPC that the web server (and the database server) is residing in. So you allow HTTP and SSH access.
  • Creating the database: Go to a release then RAILS_ENV=production bundle exec rake db:create.
  • Starting up Puma: Put the puma in the Capfile. Then, the commands are: bundle exec cap puma:start puma:stop puma:restart.
require "capistrano/puma"
install_plugin Capistrano::Puma
  • If no CSS, maybe cause the nginx server isn’t set up to use Capistrano’s conventions.
  • Time Machine status: tmutil status.
