Capistrano ssh user can't write files

Question

I am trying to have capistrano deploy my rails app to a vps.

I logged into the vps, added a new 'deployer' user and gave him sudo privileges by:

adduser deployer

and in visudo

deployer    ALL=(ALL:ALL) ALL

I installed rvm, ruby, postgres, postfix, and nginx. All using apt-get, latest version of ruby and rvm. In my gem file I'm using:

gem 'unicorn'

# Deploy with Capistrano
gem 'capistrano'
gem 'rvm-capistrano', '>= 1.3.0.rc11'

Trying to run cap deploy:setup, I came across a bunch of rvm errors, but fixed them by reinstalling rvm on cap deploy:setup using the following in my deploy.rb file, according to the capistrano github readme:

set :rvm_ruby_string, 'ruby-1.9.3-p392' # use the same ruby as used locally for deployment
set :rvm_install_ruby_params, '--1.9'      # for jruby/rbx default to 1.9 mode
set :rvm_install_pkgs, %w[libyaml openssl] # package list from https://rvm.io/packages
set :rvm_install_ruby_params, '--with-opt-dir=/usr/local/rvm/usr' # package support

before 'deploy:setup', 'rvm:install_rvm'   # install RVM
before 'deploy:setup', 'rvm:install_pkgs'  # install RVM packages before Ruby
before 'deploy:setup', 'rvm:install_ruby'  # install Ruby and create gemset, or:
before 'deploy:setup', 'rvm:create_gemset' # only create gemset
before 'deploy:setup', 'rvm:import_gemset' # import gemset from file

When I run cap deploy:cold, it goes through fine, until the end where it gives the error:

failed: "rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell 'ruby-1.9.3-p392' -c 'cd /home/deployer/apps/blog/releases/20130301223924 && bundle install --gemfile /home/deployer/apps/blog/releases/20130301223924/Gemfile --path /home/deployer/apps/blog/shared/bundle --deployment --quiet --without development test'" on 198.211.127.46

So I add my 'deployer' user into group 'rvm' using:

sudo usermod -G rvm deployer

And after running a cap deploy:cold, get the error:

 ** [out :: 198.211.127.46] cannot create directory `/home/deployer/apps/blog/releases/20130301223718'
 ** [out :: 198.211.127.46] : Permission denied

Any insight would be greatly appreciated. I'm almost there.

Here's my deploy.rb file:

require "bundler/capistrano"
require "rvm/capistrano"

server "198.211.127.46", :web, :app, :db, primary: true

set :port, 46000
set :application, "blog"
set :user, "deployer"
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, true
set :keep_releases, 5

set :scm, "git"
set :repository, "[e-mail]:myusername/#{application}.git"
set :branch, "master"

default_run_options[:pty] = true
ssh_options[:forward_agent] = true

Answer 1

Try with

chown -R deployer /home/deployer

Answer 2

Make sure all of the folders are owned by deployer. :)
