I have tryed many advises from stack, but nosing works for me.
my deploy.rb
deploy.rb:
require "bundler/capistrano"
server "xxx.xxx.xxx.xxx", :web, :app, :db, primary: true
set :application, "app"
set :user, "user"
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false
set :scm, "git"
set :repository, "git#github.com:git_user/#{application}.git"
set :branch, "master"
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
after "deploy", "deploy:cleanup" # keep only the last 5 releases
namespace :deploy do
%w[start stop restart].each do |command|
desc "#{command} unicorn server"
task command, roles: :app, except: {no_release: true} do
run "/etc/init.d/unicorn_#{application} #{command}"
end
end
task :setup_config, roles: :app do
sudo "ln -nfs #{current_path}/config/nginx.conf /etc/nginx/sites-enabled/#{application}"
sudo "ln -nfs #{current_path}/config/unicorn_init.sh /etc/init.d/unicorn_#{application}"
run "mkdir -p #{shared_path}/config"
put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml"
puts "Now edit the config files in #{shared_path}."
end
after "deploy:setup", "deploy:setup_config"
task :symlink_config, roles: :app do
run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end
after "deploy:finalize_update", "deploy:symlink_config"
desc "Make sure local git is in sync with remote."
task :check_revision, roles: :web do
unless `git rev-parse HEAD` == `git rev-parse origin/master`
puts "WARNING: HEAD is not the same as origin/master"
puts "Run `git push` to sync changes."
exit
end
end
before "deploy", "deploy:check_revision"
#rake seed task
desc "Seed the database on already deployed code"
task :seed, :only => {:primary => true}, :except => { :no_release => true } do
run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:seed"
end
desc "Seed the database on already deployed code"
task :drop, :only => {:primary => true}, :except => { :no_release => true } do
run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:drop:all"
run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:create:all"
run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:migrate"
end
end
in my production.rb I have
config.assets.compress = true
and my capfile
load 'deploy'
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'
Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) }
load 'config/deploy' # remove this line to skip loading any of the default tasks
local precompile with "bundle exec rake assets:precompile RAILS_ENV=production --trace" executes without any errors.
Where is my mistake? Hot to debug it? Or maybe somewhere is some log file for capistano in which a can look for more details?

Answer 1

I find an answer by my own
delete "load 'deploy/assets'" from capfile, and run
cap deploy:cold
this will work without an error, but only on initial deploy. Then as usual "sudo service nginx restart" on server, and add back deleted snippet.
And BAMM!! It works :)

Answer 2

You are out of RAM by the sounds of it, this question and answer helped me out - I increased the swap on digital ocean server and everything worked fine: deploy with capistrano failing

Answer 3

For anyone who face the same problem and Andrey answer don't work stop the server "sudo service nginx stop" then cap deploy and then start the server again "sudo service nginx start". It worked for me.
