卡皮斯特拉诺:无法启动独角兽

我很难(重新)启动Unicorn,因为我正在使用Capistrano以及手动部署。

这是deploy.rb

# config valid only for current version of Capistrano
lock "3.8.1"

set :application, "project"
set :repo_url, "git@bitbucket.org:username/project.git"
set :branch, "master"
set :tmp_dir, '/home/deployer/tmp'

set :deploy_to, "/home/deployer/apps/project"
set :keep_releases, 5


set(:executable_config_files, %w(
  unicorn_init.sh
))

# files which need to be symlinked to other parts of the
# filesystem. For example nginx virtualhosts, log rotation
# init scripts etc.
set(:symlinks, [
  {
    source: "nginx.conf",
    link: "/etc/nginx/sites-enabled/default"
  },
  {
    source: "unicorn_init.sh",
    link: "/etc/init.d/unicorn_#{fetch(:application)}"
  },
  {
    source: "log_rotation",
   link: "/etc/logrotate.d/#{fetch(:application)}"
  },
  {
    source: "monit",
    link: "/etc/monit/conf.d/#{fetch(:application)}.conf"
  }
])


namespace :deploy do    
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      invoke 'unicorn:restart'

    end
  end
  after :publishing, :restart

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end  

  desc "Make sure local git is in sync with remote."
  task :check_revision do
    on 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
  end
  before "deploy", "deploy:check_revision"
end

在这个部署过程中,这是Capistrano给我的错误:

SSHKit::Runner::ExecuteError: Exception while executing as deployer@IP: Exception while executing as deployer@IP: bundle exit status: 1
bundle stdout: Nothing written
bundle stderr: master failed to start, check stderr log for details

这是独角兽日志:

      /home/deployer/apps/project/shared/bundle/ruby/2.4.0/gems/unicorn-5.2.0/lib/unicorn/socket_helper.rb:122:in `initialize'

It says **    Errno::EADDRINUSE: Address already in use - connect(2) for /tmp/unicorn.project.sock** -- however, what does it mean exactly? How to fix it?

I tried to run Unicorn also manually from the server - `bundle exec unicorn -D -c config/unicorn/production.rb -E production`, but only got

> master failed to start, check stderr log for details

that's pointing out on the error message from the log above.
