Pascal's svn and Capistrano Cheat Sheet
Posted on Mon Apr 24 17:27:00 UTC 2006
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 domain.net 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://domain.net/home/psq/svn/domainsvn
mkdir domainsvn
cd domainsvn
svn co svn+ssh://domain.net/home/psq/svn/domainsvn/trunk .
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, “domain.net”
set :repository, “svn+ssh://domain.net/home/#{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”
end
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.
A word from nano RAILS sponsors
Internet marketing is as old as the internet, and someone with a strong internet marketing program will thrive. Some one having a deep experience of internet marketing online can successfully start home based business and run it very successfully. Online businesses are creating more and more work from home jobs and people are getting more domain hosting services for the launch of new home business sites. A work at home job not only saves time but also money and especially helps women.
