如何使用Capistrano进行部署，在没有sudo和root SSH连接的情况下重新启动unicorn服务

require 'capistrano/setup'
require 'capistrano/deploy'

# 设置部署服务器的IP地址和登录用户
server 'your_server_ip', user: 'your_username', roles: %w{app}

# 设置部署路径
set :deploy_to, '/path/to/your/app'

# 设置Git仓库地址和分支
set :repo_url, 'git@github.com:your_username/your_repo.git'
set :branch, 'master'

gem install capistrano

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

bundle exec unicorn -c /path/to/your/app/config/unicorn.rb -D
kill -QUIT `cat /path/to/your/app/tmp/pids/unicorn.pid`

# 设置部署任务名称
set :application, 'your_application_name'

# 设置unicorn服务的启动和停止命令
set :unicorn_start_cmd, "bundle exec unicorn -c #{current_path}/config/unicorn.rb -D"
set :unicorn_stop_cmd, "kill -QUIT `cat #{current_path}/tmp/pids/unicorn.pid`"

# 定义部署任务
namespace :deploy do
  desc 'Restart unicorn service'
  task :restart_unicorn do
    on roles(:app) do
      within current_path do
        execute fetch(:unicorn_stop_cmd)
        execute fetch(:unicorn_start_cmd)
      end
    end
  end
end

# 在部署完成后自动重启unicorn服务
after 'deploy:published', 'deploy:restart_unicorn'

cap production deploy
