Hi I am deploying my rails application in VPS and I have followed https://coderwall.com/p/yz8cha this blog and the problem is nginx show only 500 error page , I doubt of that my unicorn is not starts by capistrano (because if I start manually unicorn then nginx works), so how to start unicorn by cap:deploy
This is my cap file
require "bundler/capistrano"
require "rvm/capistrano"
server "104.131.206.110", :web, :app, :db, primary: true
set :application, "testvpsdo"
set :user, "navin"
set :port, 3008
set :deploy_to, "/home/#{user}/apps/#{application}"
set :deploy_via, :remote_cache
set :use_sudo, false
set :scm, "git"
set :repository, "git@github.com:navinspm/testvpsdo.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"
end
and this is the result while ps aux | grep unicorn
navin 15055 0.0 4.9 161736 24688 ? Sl Aug04 0:01 unicorn master -D -c /home/navin/apps/testvpsdo/current/config/unicorn.rb -E production

so whether the problem with my unicorn?If so how to start unicorn by capistrano?
I had the same error and the reason was:
while stoping capistrano3-unicorn tries to tmp/pids/unicorn.pid by default but "unicorn.pid" was at /shared/pids/unicorn.pid.
By changing the path for unicorn.pid in unicorn.rb resolved my error.
