Pascal’s svn and Capistrano Cheat Sheet

Here’s my recipe to get a source tree commited into subversion, then setup Capistrano and then deploy the application on a production server.
I’ve done this many times, and everytime I stumble of one or more steps to find find what comes next, what path to use, etc. So here’s a note to hopefully settle this once and for all.

Assumes that the subversion database is created on under /home/psq/svn/domainsvn. Assumes that the initial “domain” directory contains trunk, tags and branches and that you are deploying the trunk.

cd domain
svn import . svn+ssh://

mkdir domainsvn
cd domainsvn
svn co svn+ssh:// .

cap -A .

svn add config/deploy.rb
svn add lib/tasks/capistrano.rake

edit deploy.rb
And initialize user, application, repository…

set :use_sudo, false
set :user, ‘psq’
set :application, “”
set :repository, “svn+ssh://{user}/svn/domainsvn/trunk”
set :deploy_to, “/home/#{user}/#{application}”

Replace defaulf roles

role :web, application
role :app, application
role :db,  application, :primary => true

Add at the end of deploy.rb. See A better alternative to killall for details.

desc “Restart the FCGI processes on the app server as a regular user.”
task :restart, :roles => :app do
  run “pkill -9 -u #{user} ruby”

Now you are ready for the first deployment.

rake remote:exec ACTION=setup

And finally, to deploy:

cap deploy [or]
cap -q deploy (for quiet output)

If you you use “migration”, as you should, to create the tables on the remote host, and every time you update the tables:

rake remote:migrate

This assumed that your app was fully configured to work in your hosting environment. And if you haven’t done that yet, now if the time to do it.
